Trachymene ornata, or spongefruit, is a slender annual herb in the family Araliaceae. [4] It is native to Australia and found in Western Australia, South Australia and New South Wales. [5] [4] [6]

Description

Trachymene ornata is an annual herb growing up to 15 centimetres (6 in) high, [5] [4] which has sparsely hairy stems. [5] The sparsely hairy leaves are deeply three-lobed almost to dissected. [5] The inflorescence is an umbel of 3-6 flowers [6] which are bisexual, white or blue, and observed (in NSW) from July to October. [5] The two-carpelled fruits split into two densely woolly mericarps with white (sometimes purplish) hairs. [6]

Habitat

It grows in rocky places, and in shallow soils [5] [4]

Taxonomy

Trachymene ornata was first described by Stephan Endlicher in 1839, [7] [8] and redescribed by Druce in 1917 as belonging to the genus, Trachymene Rudge. [1]
