Specimens collected by Schiede on the Cuesta grande de 
Chiconquiaco (Herb. Hook., mixed with C. bupleurifolia) differ 
in the appressed indumentum of the stem, but are otherwise 
similar.

This is a variety or form with narrow leaves and appressed 
indumentum. A plant collected by Heyde and Lux in Guatemala 
(Donnell Smith 3731), named C. bupleurifolia by Micheli. appa- 
rently represents the same form. Specimens from Jamaica 
(Harris 11855 and 11965), differ only in the stipules being decurrent.
