Stylidium paniculatum is a dicotyledonous plant that belongs to the genus Stylidium (family Stylidiaceae). It is an herbaceous annual that grows from 10 to 35 cm tall. Oblanceolate or obovate leaves, about 6-30 per plant, form either a basal rosette with stems absent or in terminal rosettes when plant stems are present. The leaves are generally 10-31 mm long and 3-9 mm wide. This species produces one scape per plant. Inflorescences are 10-25 cm long and produce pink flowers that bloom from November to April in their native range. S. paniculatum is endemic to eastern Australia from Dalveen, Queensland to Tenterfield, New South Wales at elevations of 800 to 1000 metres. Its typical habitat has been reported as moist sandy soils on granite substrates along creeks, drains, or low-lying flats.
