Description
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.
