Xanthosia peduncularis is a spreading perennial herb in the family Apiaceae and is endemic to the south of Western Australia. It has trifoliate leaves at the base of the plant and cream-coloured flowers in a compound umbel with 3 or 4 rays.
Xanthosia peduncularis is a spreading perennial herb that typically grows to a height of about 15 cm (5.9 in). Its leaves are trifoliate, arranged at the base of the plant, the leaflets linear or wedge-shaped. The flowers are arranged in a compound umbel with the flowers arranged in 3 or 4 rays and a few central flowers. There are narrow involucral bracts that are longer than the flowers and the sepals are heart-shaped. Flowering occurs from September to November. [2] [3]
Xanthosia peduncularis was first formally described in 1867 by George Bentham in his Flora Australiensis from specimens collected by James Drummond. [4] The specific epithet (peduncularis) means "pedunculate". [5]
This species of xanthosia grows in gravelly sand in the Esperance Plains bioregion of southern Western Australia. [3]
Xanthosia peduncularis is listed as "Priority Three" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions, [3] meaning that it is poorly known and known from only a few locations but is not under imminent threat. [6]
