Motivation

Aspects of the leaf shapes are important identifying feature(s) of many plant species. Leaf shapes reflect essential evolutionary adaptations of the plant to its environment.

There is no good way to encode such essential plant data on Wikidata so far. Using has characteristic (P1552) seems to be the best we can do so far (e.g. Silene nutans (Q157950)has characteristic (P1552)lanceolate leaf (Q25501730)). Without dedicated properties, it would have to hold a lengthy list of pretty varied characteristics such as root shape, tuber formation, leaf vein patterns, leaf margin shape, growth habit, drought tolerance, fruit surface structure, ... Alternatively, with explicit reference to shape, we'd have to do more unwieldy statements like Silene nutans (Q157950)has part(s) (P527)leaf (Q33971)shape (P1419)lanceolate leaf (Q25501730), which need the useless, often redundant statement that a plant has leaves.

 Question Many databases have separate properties for e.g. leaf margin (entire, serrate, lobed, wavy, ...), leaf shape (lanceolate, elliptical, ovate, orbicular, needle-shaped, ...), leaf type (simple, compound, pinnate, sheath, frond, ...), leaflet count, leaflet shape, ... What would be the advantages for having several separate properties?--Cartoffel (talk) 23:58, 18 February 2024 (UTC)

 Support Properties describing the morphology of taxa in perspective can be used to create a species identifier. For example, how this is implemented on the website https://www.plantarium.ru/lang/en/page/find.html Wikidata already has properties has fruit type (P4000), foliage type (P10906), flower color (P2827), inflorescence (P3739). And the 'leaf morphology' is similar to them. --Afanasovich (talk) 08:25, 31 March 2024 (UTC)
