Description

The species climbs to 10 or more metres in height and has a watery sap.[2][3] The glossy leaves are lanceolate, up to 20 centimetres long and 4 centimetres wide, and taper towards the tip.[3] Juvenile leaves are narrower and new growth is down-covered. Small, sweetly scented yellow and brown flowers are produced in loose terminal panicles between August and December.[3] These are followed by long, slender pods which are 5 to 10 centimetres in length.[2]

Taxonomy

The species was first formally described as Lyonsia brownii by botanist James Britten in Journal of Botany, British and Foreign in 1907.[1] The species was placed in the genus Parsonsia by French botanist Marcel Pichon in 1950 in Notulae Systematicae.[1] The names Lysonia straminea and Parsonsia straminea have been misapplied to this species in the past.[1]

Cultivation

The species is not commonly cultivated and is considered too vigorous for most gardens.[3] It requires cool, moist conditions.[3] Plants are commercially available from local indigenous plant nurseries.[3]
