'''''Thomasia''''' is a genus of thirty-one species of flowering plants in the family Malvaceae. Plants in this genus are small shrubs that are endemic to the south-west of Western Australia, apart from ''T. petalocalyx'' that is native to Victoria and South Australia. The leaves are simple with leaf-like stipules at the base of the petiole, the flowers bisexual with five papery, petal-like sepals, usually five petals and five stamens opposite the petals. The fruit is a capsule covered with star-like hairs.<ref name="RBGV">{{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}}</ref><ref name=FloraBase>{{FloraBase | name = ''Thomasia'' | id = 21785}}</ref><ref name="efloraSA">{{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}}</ref>
