An erect evergreen tree or shrub with a height of 1.5 metres (5 ft) to 7 metres (23 ft).[2] The plant has conspicuous and attractive inflorescence composed of racemes with yellow flowers. The plant flowers through the spring time between the months of September to January.[3] The leaves of the plant are leathery and are arranged in whorls, most typically with three leaves per whorl. The leaves are generally regular in shape between 40 millimetres (2 in) to 170 millimetres (7 in) in length and 4 millimetres (0 in) to 30 millimetres (1 in) in width and have pointed tips. [4]
C. lanceolota occurs in the South West corner and South Coast of Western Australia. It grows well in sandy soils in areas that are damp, particularly along watercourses, swamps and culverts.[2]
Seeds can be collected from the plant but the pods the seeds are found in should be left to dry on the plant before they are broken open. The seeds should be scarified before sowing.[5]
