Arabidella trisecta

Arabidella trisecta (common name - shrubby cress)[2] is a species of flowering plant belonging to the family Brassicaceae.[1] It was first described in 1853 by Ferdinand von Mueller as Erysimum trisecta,[3][4] but was transferred to the genus, Arabidella in 1924 when by Otto Eugen Schulz elevated Mueller's subgenus Arabidella to genus status.[3][5] No type specimen was indicated by Mueller in 1853, and in 1965 Elizabeth A. Shaw specified the lectotype as MEL 758 and a paralectotype MEL 0000778A, both collected by Mueller from Spencers Gulf in South Australia.[6]

Its native range is Australia,[1] where it is found throughout the mainland[7] in semi-arid regions.[8][2]

It is a woody shrub, growing to 30 cm in height.[2] Its stems are terete, quadrangular or fluted, usually having papillae (little nipple shaped bumps) on the ribs.[2] The leaves are 2 to 3 lobed and do not form a basal rosette. The fruit is typically erect and linear (10–40 mm long, 1 mm wide). It flowers from winter to spring.[2]
