Plants in this genus are small shrubs that are [endemic](/source/Endemism) to the south-west of Western Australia, apart from ''[T. petalocalyx](/source/Thomasia_petalocalyx)'' that is native to Victoria and South Australia. The leaves are [simple](/source/Leaf) with leaf-like [stipule](/source/stipule)s at the base of the [petiole](/source/Petiole_(botany)), the flowers [bisexual](/source/Plant_reproductive_morphology) with five papery, petal-like [sepal](/source/sepal)s, usually five petals and five [stamen](/source/stamen)s opposite the petals. The fruit is a [capsule](/source/Capsule_(botany)) covered with star-like hairs.{{cite web |last1=Short |first1=Philip Sydney |title=''Thomasia'' |url=https://vicflora.rbg.vic.gov.au/flora/taxon/3bbf921f-f404-41dd-bce9-dac73d2769b6 |publisher=Royal Botanic Gardens Victoria |access-date=11 December 2020}}{{FloraBase | name = ''Thomasia'' | id = 21785}}{{cite web |title=''Thomasia'' |url=http://www.flora.sa.gov.au/cgi-bin/speciesfacts_display.cgi?form=speciesfacts&name=Thomasia |publisher=State Herbarium of South Australia |access-date=11 December 2020}} ==Taxonomy== The genus ''Thomasia'' was first formally described in 1821 by [Jaques Étienne Gay](/source/Jaques_%C3%89tienne_Gay) in ''[Mémoires du Muséum d'Histoire Naturelle](/source/M%C3%A9moires_du_Mus%C3%A9um_d'Histoire_Naturelle)''.{{cite web|title=''Thomasia''|url= https://id.biodiversity.org.au/instance/apni/469612 |publisher=APNI|accessdate=11 December 2020}}{{cite journal |last1=Gay |first1=Jaques E. |title=Monographie des Cinq Genres de Plantes, Lasiopétalées |journal=Mémoires du Muséum d'Histoire Naturelle |date=1821 |volume=7 |pages=450–452 |url=https://www.biodiversitylibrary.org/item/85088#page/492/mode/1up |access-date=11 December 2020}} The name ''Thomasia'' honours Pierre Thomas, his son Abraham, and Abraham's sons Philippe, Louis and Emmanuel, a family of Swiss plant collectors.{{cite book |last1=Sharr |first1=Francis Aubi |last2=George |first2=Alex |title=Western Australian Plant Names and Their Meanings |date=2019 |publisher=Four Gables Press |location=Kardinya, WA |isbn=9780958034180 |page=118 |edition=3rd}} ==Species list== The following is a listed of ''Thomasia'' species recognised by the [Australian Plant Census](/source/Australian_Plant_Census) as at December 2020:{{cite web |title=''Thomasia'' |url=https://biodiversity.org.au/nsl/services/search?product=APC&tree.id=51209179&name=Thomasia&inc._scientific=&inc.scientific=on&inc._cultivar=&max=1000&display=apc&search=true |publisher=Australian Plant Census |access-date=11 December 2020}} *''[Thomasia angustifolia](/source/Thomasia_angustifolia)'' [Steud.](/source/Steud.) - narrow-leaved thomasia *''[Thomasia brachystachys](/source/Thomasia_brachystachys)'' [Turcz.](/source/Turcz.) *''[Thomasia cognata](/source/Thomasia_cognata)'' [Steud.](/source/Steud.) *''[Thomasia dielsii](/source/Thomasia_dielsii)'' [E.Pritz.](/source/E.Pritz.) *''[Thomasia discolor](/source/Thomasia_discolor)'' [Steud.](/source/Steud.) *''[Thomasia foliosa](/source/Thomasia_foliosa)'' [J.Gay](/source/J.Gay) *''[Thomasia × formosa](/source/Thomasia_%C3%97_formosa)'' [Paust](/source/Paust) *''[Thomasia gardneri](/source/Thomasia_gardneri)'' [Paust](/source/Paust) - Mount Holland thomasia *''[Thomasia glabripetala](/source/Thomasia_glabripetala)'' [S.J.Patrick](/source/S.J.Patrick) *''[Thomasia grandiflora](/source/Thomasia_grandiflora)'' [Lindl.](/source/Lindl.) - large-flowered thomasia *''[Thomasia macrocalyx](/source/Thomasia_macrocalyx)'' [Steud.](/source/Steud.) *''[Thomasia macrocarpa](/source/Thomasia_macrocarpa)'' [Endl.](/source/Endl.) - large-fruited thomasia *''[Thomasia microphylla](/source/Thomasia_microphylla)'' [Paust](/source/Paust) *''[Thomasia montana](/source/Thomasia_montana)'' [Steud.](/source/Steud.) - hill thomasia *''[Thomasia multiflora](/source/Thomasia_multiflora)'' [E.Pritz.](/source/E.Pritz.) *''[Thomasia paniculata](/source/Thomasia_paniculata)'' [Lindl.](/source/Lindl.) *''[Thomasia pauciflora](/source/Thomasia_pauciflora)'' [Lindl.](/source/Lindl.) - few-flowered thomasia *''[Thomasia petalocalyx](/source/Thomasia_petalocalyx)'' [F.Muell.](/source/F.Muell.) - paper flower *''[Thomasia purpurea](/source/Thomasia_purpurea)'' ([Dryand.](/source/Dryand.))
