Abstract
This document describes the schema available from the APD namespace. The APD offers detailed descriptions for more than 500 plant trait concepts. It includes trait focused on plant morphology, plant nutrient concentrations, plant physiology, plant life history, and plant fire response. The definitions will be useful to researchers from diverse disciplines, including plant functional ecology, plant taxonomy, and conservation biology. All trait concepts are supported by comprehensive metadata including trait descriptions, allowable trait values, allowable ranges, preferred units, keywords, references, and links to matches in a selection of trait databases. The traits describe here also fully support the AusTraits plant trait database, <doi.org/10.5281/zenodo.3568417>.

1. Introduction
The APD is a compilation of the traits concepts used by AusTraits, a database of Australian plant traits. APD includes definitions for nearly 500 traits pertaining to plant functional ecology and plant morphology. The metadata for each trait concept has been reviewed by multiple people. Metadata includes a trait definition, accepted units and ranges (for numeric traits), allowable values (for categorical traits), keywords and trait groupings to enhance trait findability, references, and links to identical/similar traits in other trait databases. APD will be published in a machine-readable format (rdf representation), allowing the traits to be readily re-used by other databases. This is a human-friendly output, with embedded links to the references, other trait databases and keywords/concepts borrowed from other ontologies.
The APD is a community resource and we welcome any suggestions for edits, including additional key references for each trait or other trait databases for which we should add links.
2. Trait groups
The APD Trait groups express broad trait groupings, with each trait concept mapped into one or more trait groups as narrower
concepts.

A whole plant morphology trait [TO:0000398] which is the maximum [NCIT:C25564] vertical [PATO:0001854] height [PATO:0000119] of the vegetative shoot system [PO:0025607] for a taxon [NCIT:C40098] in a given population [PCO:0000001] or location [NCIT:C25341]. Maximum vertical height of the vegetative shoot system for a taxon in a given location. |
comments | This trait is not meant to document the height of all individuals sampled, but instead the maximum height for a typical mature individual within a population or across a taxon. The trait should only be scored for self-supporting plants, not climbers whose height is dependent on the surrounding vegetation. The documented height should be the maximum height achieved by vegetative shoots, not the height reached by reproductive shoots, as it represents the plant’s access to light. |

alternative label | plant_diameter_breast_height |
description |
A stem morphology trait [TO:0000361] which is the maximum [NCIT:C25564] diameter at breast height [ECSO:00000549] for a taxon [NCIT:C40098] in a given population [PCO:0000001] or location [NCIT:C25341]. Maximum diameter at breast height (DBH) for a taxon in a given location. It is commonly referred to as ‘DBH’. |
comments | This trait is always meant to be measured at ‘breast height’, 1.4 m above the ground surface. However, for short plants this will not always be the case, so it is advised to read the methods to confirm at what height plant diameters have been recorded. This trait is not meant to document the DBH of all individuals sampled, but instead the maximum DBH for a typical mature individual within a population or across a taxon. |

Maximum vertical height of the vegetative shoot system of a non-self-supporting taxon (i.e. a vine, liana, or other climbing plant) in a given location. |
comments | While this trait is intended to indicate the height of climbing plants, the height of an epiphyte relative to the soil surface could also be documented here. All heights reported for this trait will be dependent on the height of the surrounding vegetation. |

description |
A leaf area trait [TO:0000540] which is the 2-D [PATO:0001709] area [PATO:0001323] of the leaf lamina [PO:0020039] and petiole [PO:0020038]. For some species the area of a leaf analogue is reported, possibly a leaflet [PO:0020049], cladode [PO:0025354], or phyllode [PO:0025335]. The 2-dimensional projected (scanned) area of the surface of a leaf or a leaf analogue (leaflet, cladode, phyllode). |
comments |
This trait includes measurements of leaves and leaf analogues, including leaflets, cladodes, and phyllodes. When a measurement is made on a leaf analogue, the tissue measured should be documented as part of the methods or noted as a context or under measurement_remarks . Leaflet area can alternatively be mapped to the trait leaflet_area . It is most common for leaf area measurements to include the petiole; the measurement methods should indicate if the petiole is included in or excluded from the leaf area measurements. For terete leaves, leaf area should still be recorded as the 2-dimensional projected area.

description |
The maximum [NCIT:C25564] width [PATO:0000921] axis of a leaf [PO:0025034] measured perpendicular to [PATO:0002434] the leaf length [PATO:0000122]. Maximum width axis of a leaf or a leaf analogue (a leaflet, cladode, or phyllode), measured perpendicular to the leaf length. |
comments |
This trait refers to the single line marking the maximum width of the leaf lamina. For a compound leaf the correct measure is the maximum width of the total leaf blade. It is the width measure that will be reported in taxonomic treatments. It is not the effective_leaf_width , a trait that records the diameter of the largest circle that can be drawn within the leaf lamina. If a leaf analogue (leaflet, cladode, or phyllode) is measured instead of a true leaf, this should be noted as a context or under measurement_remarks .

description |
The thickness [PATO:0000915] of the leaf lamina [PO:0020039], measured away from the midrib [PO:0020139]. Thickness of the leaf lamina, generally measured away from the midrib. |
comments |
Leaf thickness measurements submitted from the ecological literature will generally avoid the midrib, but not avoid lower order leaf veins. In contrast, leaf thickness measurements from the taxonomic literature will usually include any veins or midribs, because in this literature leaf thickness is generally measured on succulent plants. The methods field should document whether the midrib was explicitly included, excluded, or ignored.

This trait includes measurements of leaves and leaf analogues, including leaflets, cladodes, and phyllodes. When a measurement is made on a leaf analogue, the tissue measured should be documented as part of the methods or noted as a context or under measurement_remarks . Leaflet dry mass can alternatively be mapped to the trait leaflet_dry_mass . It is most common for leaf dry mass measurements to include the petiole; the measurement methods should indicate if the petiole is included in or excluded from the leaf dry mass measurements.

It is most common for leaf fresh mass measurements to include the petiole; the measurement methods should indicate if the petiole is included in or excluded from the leaf fresh mass measurements. A source of variation for this trait will be how leaves are stored and if they are partially rehydrated before weighing; these details should be documented in the methods.

description |
A leaf morphology trait [TO:0000748] which is the ratio [PATO:0001470] of the leaf dry [PATO:0001824] mass [PATO:0000125] to the leaf [PO:0025034] area [PATO:0001323], measured on an entire leaf, including the entire leaf lamina [PO:0020039] and the petiole [PO:0020038]. The ratio of leaf dry mass to leaf area, measured on an entire leaf including the petiole; LMA. (The inverse of specific leaf area, SLA.) |
comments |
Leaf mass per area includes measurements submitted as specific_leaf_area (SLA); they are simply inverted. Leaf mass per area is explicitly measured on an entire leaf, including the petiole. Measurements made on a piece of the leaf lamina, excluding petiole and midrib, are a separate trait leaf_lamina_mass_per_area . If measurements are made on the entire leaf lamina, but the petiole is excluded, this should be noted in the methods or under measurement_remarks .

description |
A leaf shape trait [TO:0000492] which is the shape [PATO:0000052] and form of a leaf [PO:0025034], considering the ratio [PATO:0001470] of leaf length [PATO:0000122] to leaf width [PATO:0000921], the position [PATO:0000140] of the maximum [NCIT:C25564] width dimension relative to the length axis [NCIT:C25154], and the curvature [PATO:0001591] of the leaf margin [PO:0020128]. Shapes of a leaf or leaflet. |
comments |
This trait includes terms to describe the shape of leaves, regardless of if they are broad leaves, scale-like leaves, or needle-like leaves. For compound leaves, it is generally the shape of the leaflet that is recorded. See the trait leaf_type for broad terms referencing leaf form (broadleaf, needle, scale) and plant_photosynthetic_organ for terms indicating which plant organ or tissue functions as the plant’s primary photosynthetic organ (e.g. phyllode, cladode, article).

A leaf shape trait [TO:0000492] which indicates types [NCIT:C25284] of lobed leaves [PO:0025517] and compound leaves [PO:0020043], including the arrangement [NCIT:C61532] of the lobes or leaflets [PO:0020049] with respect to the midrib [PO:0020139] or other primary leaf veins [PO:0025413] and the number of orders of axes [NCIT:C25154] across which there are incisions or divisions. A trait that captures the types of lobed leaves and compound leaves, including the arrangement of the lobes or leaflets relative to the midrib or other primary veins and the number of orders of axes across which there are incisions or divisions. |
comments |
This trait provides detailed description of leaf divisions, beyond what is captured in leaf_compoundness (simple versus compound) and leaf_lobation (entire versus lobed). The term ‘divided’ is meant to indicate lobing, such as ‘trichotomously divided’, but as ‘divided’ is also used in some context to indicate the divisions of leaves into leaflets, it is avoided as a trait value for this trait.

description |
A leaf morphology trait [TO:0000748] which is the presence or absence of epicuticular wax [PO:0025388] on the leaf lamina [PO:0020039] of a fully expanded adult phase leaf [PO:0006340], giving the leaf lamina surface a white-coloured [PATO:0000014] or blue-coloured waxy [PATO:0002384] appearance, termed glaucous. Variable describing whether mature adult phase leaves have a glaucous appearance, the colour due to being covered with a smooth, usually whitish to bluish epicuticular wax that can easily be rubbed off. |
comments | The accompanying methods should specify if the trait was scored on the upper (adaxial) or lower (abaxial) surface of the leaf; in the absence of any notes, it is assumed the trait was scored on the upper (adaxial) leaf surface. |

A leaf pubescence trait [TO:0002722] which is the presence or absence of trichomes [PO:0006504] (hairs) on the leaf lamina [PO:0020039] of a fully expanded adult phase leaf [PO:0006340]. Variable describing whether mature (fully expanded) adult phase leaves on adult plants have hairs (trichomes). |
comments | This trait captures the presence or absence of hairs on mature (fully expanded), adult phase leaves on adult plants. Best practice is to sample leaves that are recently fully expanded, since older leaves have often shed many of their hairs. The accompanying methods should specify if the trait was scored on the upper (adaxial) or lower (abaxial) surface of the leaf; in the absence of any notes, it is assumed the trait was scored on the upper (adaxial) leaf surface. |

description |
A leaf [PO:0025034] spatial pattern [PATO:0000060] trait which is the position [TO:0000541] and arrangement [NCIT:C61532] of leaves between stem nodes [PO:0020141], indicating how leaves align and cluster along the vegetative shoot system [PO:0025607]. Leaf arrangement across stem nodes, indicating the 3-dimensional arrangement of leaves along the length of the stem. |
comments |
Leaf arrangement, as defined for this trait, indicates patterns of leaf arrangement across nodes, including both formal terms (decussate, distichous, spiral) as well as indications of leaf clustering due to variation in internode length. See the trait leaf phyllotaxis for terms describing leaf arrangement at a single node. See the trait stem_growth_habit for whole-plant leaf pattern terms, such as rosette .

Cross-sectional area of a stem without bark. |
comments | This is not a trait itself, since it is dependent on the location sampled. However, values might be reported that are effectively contexts for another trait, such as bark thickness or Huber value. Although it is defined as the diameter of the entire stem without bark, it is generally measured on narrow branches that have not yet developed heartwood and therefore is the cross-section of sapwood. |

description |
A root system morphology trait [TO:0000985] which are categorical [STATO:0000252] trait values that capture the branchiness [PATO:0002009] and texture [PATO:0000150] of the root system [PO:0025025] and the root system depth [TO:0001058]. Categorical root system descriptions that indicate the branchiness and texture of the root system and the depth of the root system. |
comments | The trait values listed are those specified in the root system classification scheme proposed by Cannon in 1949. |
value type | categorical variable |
has narrower |
root_system_classification_type_i The primary root is fibrous or fleshy and is relatively long; mesophytic. root_system_classification_type_ii The primary root is relatively short and is fibrous. Roots are well branched in a dry habitat but branch little in one that is wet. root_system_classification_type_iii The primary root is usually long and fibrous. The first order lateral roots are well branched and are usually short; they are rather evenly distributed along the primary root; xerophytic. root_system_classification_type_iv The primary root is usually long and slender like that of Type II. The first order lateral roots are well branched. Those closest to the surface of the ground, or not far below, are relatively long; xerophytic and mesophytic. root_system_classification_type_v The primary root is divided-forked or branched-and fibrous, and with few first order lateral roots, or, in age, apparently with none; xerophytic. root_system_classification_type_vi The primary root is usually as in Type V. The first order lateral roots are mostly on the upper portion of the primary root and are thus relatively superficial; xerophytic or in well aerated sandy soil where the rainfall is not light. root_system_classification_type_vii Adventitious roots that are in one group and arise on a short horizontal, or vertical, axis of the shoot. They are fibrous or fleshly; mesophytic and hydrophytic. root_system_classification_type_viii Adventitious roots that are in one group and are fibrous and fleshy, or fibrous and thick. The fibrous adventitious roots are absorbing-anchoring roots and are usually with laterals to the second order; meophytic. root_system_classification_type_ix Adventitious roots that arise on the aerial stem and branches of some herbaceous taxa, shrubs, and trees; on creepers, vines, and runners; and on subterranean rhizomes and stolons. |

description |
A root system morphology trait [TO:0000985] which is a model parameter [STATO:0000034] indicating the distribution [PATO:0000060] of a plant’s roots [PO:0009005] with depth [PATO:0001595]. To calculate the model parameter, the required input is a plot of the cumulative root distribution from the surface, where [Y] is the cumulative fraction of roots from the surface to a depth [d]. An asymptotic nonlinear model is used to describe the vertical root distribution: Y = 1 - b^d where Y is the cumulative root fraction from the surface to soil depth d in centimeters and b the estimated parameter. Root biomass depth distribution coefficient (‘B’ from Gale & Grigal 1987), where high values indicate that root biomass is allocated deeper in the soil. To calculate the model parameter, the required input is a plot of the cumulative root distribution from the surface, where [Y] is the cumulative fraction of roots from the surface to a depth [d].

description |
An androecium morphology trait [TO:0000994] which is the length [PATO:0000122] and shape [PATO:0000052] of the stomia [PO:0020101] that form the anther dehiscence zone [PO:0005011]; stomia are the usually slit-like [PATO:0002482] openings in the anther [PO:0009066] through which pollen [PO:0025281] is released. Anther dehiscence refers to the type of opening of the anther when releasing its pollen through the stomia. |

description |
An androecium morphology trait [TO:0000994] which is the position [PATO:0000140] and orientation [PATO:0000133] of the stomia [PO:0020101] that form the anther dehiscence zone [PO:0005011]; stomia are the slit-like [PATO:0002482] openings in the anther [PO:0009066] through which pollen [PO:0025281] is released. Orientation of anther at anthesis. |
comments | Anthers of angiosperms are rather uniform in their basic structure. They normally have four microsporangia (pollen sacs) that are arranged pair-wise in two thecae. The two microsporangia of a theca usually release their pollen grains through a common opening (stomium). Often, it is difficult to establish anther orientation clearly in a flower as this is a gradual feature with many intermediate stages. Definition and trait values derived from Schoenenberger et al. (2020) for their character ‘311. Anther orientation (D1)’ |

description |
A floral organ morphology trait [TO:0000862] which is whether a filament [PO:0009067] is present [PATO:0000467] or absent [PATO:0000462], and if present, the shape [PATO:0000052] and the relative length [PATO:0000122], width [PATO:0000921], and thickness [PATO:0000915] of the filament. Trait that considers the absence or presence of the filament, and in the latter case, the shape of the filament. Shape is considered in terms of length and width and is defined in relation to anther length/width. |
comments | The width of the filament may thus either be broad as in laminar (e.g., Eupomatiaceae) or bulky stamens (e.g., Chloranthaceae), or narrow (filamentous) as found in many core eudicots groups (e.g., Rosaceae). This trait is considered inapplicable when filaments are entirely fused with each other or to the perianth. Definition and trait values derived from Schoenenberger et al.

description |
A floral organ morphology trait [TO:0000862] which is the proportion [PATO:0001470] of the length [PATO:0000122] of the stamen [PO:0009029] (or staminode [PO:0009077]) filaments [PO:0009067] that are fused [NCIT:C124537] to the innermost perianth [PO:0009058] organ [PO:0009008] at anthesis [PO:0009068]. The fusion of filaments with the innermost perianth organs at anthesis on a continuous scale, from 0 (filaments completely free from perianth) to 1 (filaments fused along their entire length with the perianth; the ‘entire length’ of the filament is defined as the distance between the floral base and the joint between filament and anther). |
comments | Partial fusion is recorded using an approximate number between these two extremes (e.g., 0.1 corresponds to basal fusion, 0.5 to fusion along half of the length of perianth parts). If two (or more) stamen whorls (including staminodial whorls) differ in their extent of filament fusion with the perianth, this trait is recorded as a range of values. For example, if the filaments of an outermost stamen whorl are fused, up to 90% of their length, but an inner whorl only up to 50%, the trait is assigned a range of 0.5 to 0.9. The rationale for this is to provide a general trait that allows comparison of fusion among all angiosperms. Definition derived from Schoenenberger et al. (2020) for their character ‘308.

description |
A floral organ morphology trait [TO:0000862] which is the position [PATO:0000140] of the ovules [PO:0020003] within the ovary [PO:0009072], known as placentation [APD:glossary/40074]. The different types of placentation in apocarpous/unicarpellate and in syncarpous gynoecia. |
comments | In apocarpous and unicarpellate gynoecia, placentation is often described as marginal as the ovules are usually attached along the ventral slit (i.e., the zone where the carpel margins become postgenitally closed during carpel development). In syncarpous gynoecia there are three main types of placentation, 1) axile placentation refers to ovaries where the ovules are placed in the angle between carpel flanks in the center of the ovary; 2) in ovaries with parietal placentation the ovules attach to the ovary wall where two carpels meet; 3) in ovaries with free-central placentation the ovules are attached to a central column that emerges from the base of the ovary and protrudes into the non-septate ovary. It is not unusual that syncarpous gynoecia show a transition from proximally axile to a distally parietal placentation (e.g., Polemoniaceae). Basal and apical placentation may occur both in apocarpous/unicarpellate and in syncarpous gynoecia. Usually there is one longitudinal series of ovules attached to each carpel margin. However, both in apocarpous/unicarpellate and in syncarpous gynoecia there may be more than one series of ovules at the flanks of a carpel. These latter cases are referred to as laminar (or laminar-diffuse) placentation (e.g., in some Nymphaeaceae). A placenta that is protruding from its surroundings and has more than two series of ovules (either axile or parietal) is called protruding-diffuse.

description |
A floral organ morphology trait [TO:0000862] which is the position [PATO:0000140] of the plant ovary [PO:0009072] relative to the other flower [PO:0009046] organs [PO:0009008], in particular whether the ovary is attached above or below the perianth [PO:0009058] organs (the petals [PO:0009032] and sepals [PO:0009031]). The position of the flower ovary relative to the insertion level of the remaining floral organs. |
comments | The ovary is the part of the gynoecium where the ovules are produced. The ovary may be located on the receptacle and thus be positioned above the insertion level of the remaining floral organs (i.e., the ovary is superior and the flower is hypogynous). Alternatively, the ovary may be embedded in the receptacle and therefore be located below the insertion level of the remaining floral organs (i.e., the ovary is inferior and the flower is epigynous). Flowers with a hypanthium may either have a superior ovary (perigyny; e.g., many Rosaceae) or an inferior ovary (epiperigyny). It is also possible that the ovary is inferior to a certain degree only, such as half-inferior, if the receptacle is surrounding the ovary to its mid-level.

Perianth differentiation

alternative label | flower_perianth_differentiation |
description |
A floral organ morphology trait [TO:0000862] which indicates whether petals [PO:0009032] and sepals [PO:0009031] are differentiated or identical and the various ways they can be identical or different. The ways in which perianth organs may look different from each other in a given flower. |
comments | Typically, outer perianth parts are sepaloid and protect the other floral organs during floral development, while inner organs are often petaloid and play a role in pollinator attraction (Endress, 1994). However, it is also possible that all parts are either sepaloid or petaloid but remain differentiated in shape, size, and/or texture. In case of spiral perianths, differentiation may be continuous (i.e., gradual), whereby two successively initiated organs are very similar or only slightly different, while the outermost and innermost organs at both ends of the spiral are very different from each other (e.g., Chimonanthus). In the special case of perianths consisting of a single whorl, they are scored as undifferentiated. This perianth differentiation trait may be seen as both functional (the parting vs. sharing of functions among perianth parts) and developmental (the expression of a genetic program for different forms of perianth parts vs. a single program for a single type of perianth part morphology). Within-whorl differentiation, whereby organs of the same whorl take different forms, is common in zygomorphic flowers (e.g., Balsaminaceae, Fabaceae, Orchidaceae) but is not taken into account with this trait. This trait is not applicable when the perianth is absent. Definition and trait values derived from Schoenenberger et al. (2020) for their character ‘234. Perianth differentiation (D1)’ |

description |
A floral organ morphology trait [TO:0000862] which is the proportion [PATO:0001470] of the length [PATO:0000122] of perianth [PO:0009058] parts (sepals [PO:0009031], petals [PO:0009032], and tepals [PO:0009033]) that are fused [NCIT:C124537] together at anthesis [PO:0009068]. Fusion of perianth organs (congenital or postgenital) at anthesis, recorded on a continuous scale, from 0 (free parts) to 1 (parts fused along their entire length). |
comments | Partial fusion was recorded using an approximate number between these two extremes (e.g., 0.1 corresponds to basal fusion, 0.5 to fusion along half of the length of perianth parts). In case of multiple whorls, this trait records within-whorl fusion. For example, if organs within each whorl are fused along their entire length, a trait value of 1 is recorded. In cases where organs of two whorls are fused into a common tubular structure, such as frequently observed in monocots (e.g., Polygonatum), the perianth is considered to be fused. If the two (or more) whorls differed in their extent of fusion, a range of trait values may be recorded. For example, if the calyx is only basally fused, up to 10% of its length, but the corolla is entirely fused, a range of 0.1 to 1 is recorded as the trait value for the species.

comments | A value of zero was scored when the perianth is absent. In flowers with perianth whorls fused along their complete length (e.g., Convolvulus), perianth parts are counted based on merism (e.g., if a calyx has 5 distinct sepals and the corolla is entirely fused, then the corolla is often interpreted to consist of five fused petals), anatomy (e.g., number of vascular traces), development (e.g., number of primordia), or comparison with closely related taxa.

description |
A floral organ morphology trait [TO:0000862] which is the count [NCIT:C25463] of pollen apertures [GO:0062074] per pollen [PO:0025281] grain. The number of apertures per pollen grain as a continuous character. |
comments | A pollen aperture is a structurally delimited region of the pollen grain wall through which the pollen tube emerges during pollen germination and which plays a role in harmomegathy. A value of zero is scored when pollen is inaperturate (i.e. when there is no distinct aperture). Aperturate pollen is scored with integer values of 1 and above. Definition derived from Schoenenberger et al. (2020) for their character ‘5000. Number of apertures (C1)’ |

A floral organ morphology trait [TO:0000862] which is the count [NCIT:C25463] of both fertile [PATO:0000955] and female sterile [PATO:0000892] carpels [PO:0009030] in a hermaphrodite [PATO:0001340] flower [PO:0009046] or female [PATO:0000383] flower. Number of fertile or sterile carpels in bisexual or female flowers, recorded as a continuous character (with integer values of 1 and above). |
comments | Includes the number of co-occurring carpellodes (sterile carpels) because this number is often more easily obtained from the literature than the actual number of fertile carpels. However, the number of carpellodes in male flowers is ignored for this character. In multicarpellate, unilocular gynoecia with complete carpel fusion up to the stigma (e.g., Primula), it may be difficult to assess the number of carpels unequivocally. In such cases, the number of carpels is scored only if it is well established based on atomical or developmental investigations. Similarly, in gynoecia where one or more carpels are reduced (e.g., in the pseudomonomerous gynoecia of some Arecaceae, Stauffer et al., 2002), the total number of structural carpels is only scored when unequivocally determined in the literature. Definition derived from Schoenenberger et al. (2020) for their character ‘401. Number of structural carpels (C1)’ |

A fruit morphology trait [TO:0002629] which indicates whether a mature [PATO:0001701] fresh [EnvThes:21976] fruit [PO:0009001] is fleshy [PATO:0002351]. Binary variable, dividing entire, true fruits into ‘dry’ versus ‘fleshy’ based on whether their botanical fruit type is fleshy when mature and fresh. |
comments | This trait explicitly refers to fruit fleshiness, not diaspore or seed fleshiness; diaspore fleshiness is a separate trait. |

Seed dry mass

alternative label | seed_dry_mass |
description |
A seed morphology trait [TO:0000184] which is the dry [PATO:0001824] mass [PATO:0000125] of a mature [PATO:0001701] seed [PO:0009010]. Dry mass of a mature seed, including both oven dried and air-dried samples. |
comments | Standard methods people will have used to dry seeds include, ‘fresh’ (at dispersal, mature); ‘air dried’ (at local ambient conditions); ‘seed bank air dried’ (to 15% relative humidity); and ‘oven dried’ (>100 deg C for a set number of hours; e.g. seed bank standard is 103 deg C for 17 hours). It is expected that some observations in AusTraits mapped onto ‘seed_dry_mass’ will actually include both the seed and some dispersal tissue, if the two cannot easily be separated; these should be mapped to ‘diaspore_dry_mass’. |

alternative label | diaspore_dry_mass |
description |
A seed morphology trait [TO:0000184] which is the dry [PATO:0001824] mass [PATO:0000125] of a seed [PO:0009010] and the seed dispersal [EnvThes:21042] structures [PATO:0000141]. Dry mass of a plant’s dispersal unit, including the seed and any dispersal appendages; synonymous with the term dispersule and often synonymous with the term disseminule. |
comments | Data mapped onto this trait have been very explicitly defined as a ‘diaspore’. There will be additional values mapped as either ‘seed_dry_mass’ or ‘fruit_dry_mass’ that are also diaspores, but have identified only as being a ‘seed’ or ‘fruit’. In addition, it is expected that some observations in AusTraits mapped onto ‘seed_dry_mass’ will actually include both the seed and some dispersal tissue, if the two cannot easily be separated. |

description |
A seed morphology trait [TO:0000184] which is the dry [PATO:0001824] mass [PATO:0000125] of the components of a seed [PO:0009010] that provide energy [PATO:0001021] to a seedling [EnvThes:20698], generally the embryo [PO:0009009] and, if present, the endosperm [PO:0009089]. Dry mass of a seed’s embryo and endosperm (if present), the components of a seed that provide energy to a seedling. These tissues are distinct from a seed’s dispersal structures or protective tissues. |

alternative label | seed_length |
description |
A seed morphology trait [TO:0000184] which is the greatest linear dimension [PATO:0001708] (axis) of a seed [PO:0009010] and is perpendicular to [PATO:0002434] the seed width [PATO:0000921] and seed height [PATO:0000119] axes [NCIT:C25154]. Longest linear seed dimension. |
comments | Observations of this trait in AusTraits are almost certainly an undocumented mix of dimensions of true seeds and diaspores. When all or part of the fruit is not easily separated from the true seed, many researchers will have recorded and submitted a diaspore length, but labeled the data ‘seed length’. The intent of this measurement is that it excludes appendages, although it is likely some submitted measurements include small appendages that are not easily separated from the seed. |
