The closely related cremnophyte, Caputia medley-woodii was common and obvious on the cliff edges with its bright yellow flowers. The important characters that distinguish this species from C. oribiensis are the teeth on the upper portion of the leaves, the felted upper and lower surfaces of the leaves, and the flower buds which are held upright.
While we saw several other interesting plants along these edges there was no sign of Caputia oribiensis. There was a Gymnosporia nemorosa covered in flowers, and clambering through a nearby shrub, Sarcostemma viminale, also in flower. Not far away we found a plant which looks very similar to Sarcostemma viminale when not in flower, Cynanchum gerrardii.

A little further growing just below the cliff edges we found the Near Threatened endemic Rhynchocalyx lawsonioides in fruit and the fairly unusual Seemannaralia gerrardii with clusters of yellow-green flowers.
Update: 5 May 2016
The plant suspected to be our target species, Caputia oribiensis, unfortunately turned out to be an atypical Kleinia fulgens - so the search goes on!
