Derris involuta (FABACEAE) Native Derris, Fish Poison Vine

A large woody vine growing into the canopy of rainforest, north from Wingham, NSW. Compound, alternate leaves with 9-13 ovate-elliptical leaflets up to 5 cm long and 2 cm wide. Pink mauve 1 cm pea flowers on arched racemes from September to October. Flattened, hairy pods to 8 cm long. Ripe March to May. Propagation from fresh seed which has been scarified. Not commonly propagated so is hard to find in nurseries.

In this image, note the absence of upward pointing sharp stipels from the leaf axils which are a characteristic of the similar looking Blood Vine Austrosteenisia blackii but not Native Derris.
