Notes
This rare species is very similar to C. johnstonii but can easily be distinguished by its shorter and, in comparison, wider leaf (which is much more like that of C. cordifolium Oliv.), the presence of small persistent bracts and its smaller fewer flowers which are usually produced two to a node.
