Commonwealth status: Vulnerable
Profile last updated: 14 Jun 2020


Slender Marsdenia is a slender climber of the milk vine group, with pairs of very finely pointed leaves and 5-6 tiny glands at the base of the leaves. The stems of Slender Marsdenia exude clear, watery sap when cut, unlike most of the milk vines which have milky sap. Clusters of small white star-shaped flowers are produced and are followed by long, narrow seed-capsules that split to release many seeds with tufts of long silky hair.


Scattered sites on the north coast of NSW north from Barrington Tops. Also occurs in south-east Queensland.
