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]

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]
