Scientific name: Tylophora woollsii
Conservation status in NSW: Endangered
Commonwealth status: Endangered
Profile last updated: 14 Jun 2020


A slender woody climber that grows to 3 m long. The paired leaves are on stalks 7 - 20 mm long, and are an elongated heart-shape with a firm texture. There are two to four tiny glands at the base of each leaf-blade and the stems exude a clear, watery sap if cut. The purple to red flowers are 5 - 6 mm in size, and are produced in late summer to autumn on zigzagging branched stalks growing from the leaf junctions. They are followed by narrow seed-capsules 5 - 8 cm long, which split to release many seeds, each of which has a tuft of silky hair.


The Cryptic Forest Twiner is found from the NSW north coast and New England Tablelands to southern Queensland, but is very rare within that range. Known on the Tablelands from the Bald Rock and Boonoo Boonoo areas north of Tenterfield.

  • Flowering occurs in summer and autumn, usually between January and March but sometimes as late as November.
  • Thought to be wind-dispersed.
  • Plants appear to persist as a network of stems under leaf litter when aerial stems are absent.
