This is a small vine with a highly branched, twining stem rarely exceeding a meter in length with which it physically supports itself on other shrubs and trees. It has small narrow leaves a few centimeters long. Its flowers are bright yellow to orange and grow in umbels. The fruit is a grooved follicle several centimeters long.
