Discussion:

This species is easily distinguished by the combination of puberulent to subhirtellous flowering branches, the puberulous lower surface of the leaf-blades, and corolla-lobes nearly as long as the corolla-tube in the staminate flowers. It ascends to a higher altitude than any of the other known species of the genus.

From K. sericantha Standi., with which it was mistaken by Standley, it is at once separated by the corolla-lobes of the staminate flower nearly equaling the corolla-tube, the more sparsely pubescent outer surface of the shorter corolla-tube, the glabrous outer surface of the calyx-tube, the smaller leaf-blades lacking a reticulate tertiary venation, the conspicuous indument on the lower surface of the leaf-blades, and apparent lack of resinous exudate on the branches or foliage.
