This Queensland endemic is a curious member of the Fan Flower (Goodeniaceae) family firstly because it is a climber and secondly because it inhabits rain forest. It has therefore been named descriptively the Climbing Fan Flower. Many of the other members of the Fan Flower family are either shrubs or herbs and usually inhabiting heath or drier forest, with the exception of Sea Lettuce (Scaevola taccada), of course, which is an archetypal shore plant.
Being a member of a botanical family one would rarely expect to see as a vine, this plant can be notoriously difficult to identify when not in flower. However there are a few features, and their combination that set it apart from other climbers. The leaves have a somewhat fleshy feel and they are toothed (sometimes only mildly) at the margins. The leaves are also arranged in an opposite manner and there is a curious ridge at the node where the leaf stalks meet.
The habitat can be quite instructive as well because it seems to be partial to wetter environments. So far I have seen it on rainforest margins and most often in tall open eucalypt forest.
