Scientific name: Senna acclinis
Conservation status in NSW: Endangered
Commonwealth status: Not listed
Profile last updated: 13 Sep 2021


Rainforest Cassia is a shrub to 3 m tall with compound leaves to 15 cm long, each with up to 6 pairs of oval-shaped leaflets at about 15 mm intervals along the central spine. There is a gland between the lower one to four pairs of leaflets. The flowers are in groups of two to five on a short stalk, hanging on the underside of the branchlets. They are bright golden yellow and cup-shaped. The seed pod is long and narrow, 12 - 15 cm long, 6 - 8 mm wide and more or less flat. Senna acclinis can easily be mistaken for introduced Senna (formerly Cassia) species which are environmental weeds.


Occurs in coastal districts and adjacent tablelands of NSW from the Illawarra in NSW to Queensland.
