As indicated in the key to species, the differences separating S. klugei and S. rubescens are well marked. The flowers of S. rubescens are larger and 5-6-merous, with larger fruits and longer leaf blades with more numerous lateral nerves. However, such collections as Aristeguieta, Blanco & Carrillo 6794 show leaf blades somewhat intermediate in size and nervation with those of S. rubescens, and are difficult to separate on leaf shape and size from such small-sized leaves as found in Steyermark 86224 pertaining to S. rubescens.
