"Stylidium tenerum" is a dicotyledonous plant that belongs to the genus "Stylidium" (family Stylidiaceae) that was described by Curt Polycarp Jaochim Sprengel in 1826. Robert Brown had described this species in 1810 under the name "S. tenellum", a name which had already been used for another species in 1805 by Olof Swartz. To add to the confusion, Rica Erickson had described and illustrated this taxon in 1958 under the name "S. uliginosum", another currently accepted name for a related species.Bean, A.R. (2000).

"S. tenerum" is an erect annual plant that grows from 3 to 20 cm tall. Obovate or orbicular leaves, about 4-10 per plant, form basal rosettes. The leaves are generally 4-17.5 mm long and 3-8 mm wide. This species generally has one to seven scapes and cymose inflorescences that are 3-20 cm long. Flowers are white. "S. tenerum" has a wide distribution ranging from eastern Queensland and extreme northeastern New South Wales up to the Wessel Islands of the Northern Territory in Australia and has even been located in Papua New Guinea. Its typical habitats include the sandy soils of creekbanks, seepage areas, and coastal lowlands in open "Melaleuca" communities. It flowers in the southern hemisphere from April to October.
