"Stylidium uliginosum" is a dicotyledonous plant that belongs to the genus "Stylidium" (family Stylidiaceae) and is one of the few species in the genus that is not native to Australia. It is an erect annual plant that grows from 4 to 15 cm tall. Obovate or elliptical leaves, about 7-16 per plant, form basal rosettes around compressed stems. The leaves are generally 4.5-11 mm long and 2-4.5 mm wide. This species generally has one to seven scapes and cymose inflorescences that are 4-15 cm long. Flowers are white. "S. uliginosum" is endemic to Southeast Asia and has a wide distribution, ranging from Thailand to the Guangdong province of southern China. The type location is in Sri Lanka, but it may be extinct there now.Wadhwa, B.M. (1997). Stylidiaceae. In M.D. Dassanayake (ed.), "A Revised Handbook to the Flora of Ceylon", Volume XI. A.A. Rotterdam: Balkema.] Earlier reports list this species as also occurring in Queensland and other parts of Australia,Good, R. (1925). On the Geographical Distribution of the Stylidiaceae. "New Phytologist", 24(4): 225-240.] but this was before subsequent revisions revealed those occurrences in Australia were really a different species, "S. tenerum", that resembled "S. uliginosum".Bean, A.R. (2000). A revision of "Stylidium" subg. "Andersonia" (R.Br. ex G.Don) Mildbr. (Stylidiaceae). "Austrobaileya" 5(4): 589-649.] Its typical habitats include sandy, moist soils in open savannah and sandy earth banks at an altitude of less than 200 metres. It flowers from October to March. "S. uliginosum" is most closely related to "S. kunthii" and "S. tenerum".
