Galea orbiculata, confined to Serrania Yutaje, is most closely related to C. 

 phelpsiae which was collected on the nearby Cerro Yavi. The first has orbicular 

 minutely denticulate sessile leaves which are totally glabrous. C. phelpsiae has 

 ovate or elliptic, crenate-serrate leaves which are sparingly but obviously 

 strigulose beneath, and are distinctly petiolate.
