From Wikipedia, the free encyclopedia
Stylidium inaequipetalum, the Ayer's Rock triggerplant, is a dicotyledonous plant that belongs to the genus Stylidium (family Stylidiaceae). It is an herbaceous perennial plant that grows from 7 to 40 cm tall. Oblanceolate leaves, about 20-100 per plant, form a basal rosette with stems absent. The leaves are generally 15-81 mm long and 2-8 mm wide. This species produces 1-11 scapes per plant. Inflorescences are 7-40 cm long and produce pink flowers with petals all free and blooms almost year-round in their native range. S. inaequipetalum is endemic to the southwestern area of the Northern Territory. Its typical habitat has been reported as sandy soils on sheltered creekbanks or in between rocks. S. inaequipetalum is most closely related to S. floribundum, though it is also closely allied with S. debile.[1]
