Arabidella trisecta (common name - shrubby cress) is a species of flowering plant belonging to the family Brassicaceae. It was first described in 1853 by Ferdinand von Mueller as Erysimum trisecta, but was transferred to the genus, Arabidella in 1924 when by Otto Eugen Schulz elevated Mueller's subgenus Arabidella to genus status. 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.
Its native range is Australia, where it is found throughout the mainland in semi-arid regions.
