Kalanchoe klopperae (Crassulaceae subfam. Kalanchooideae), a Southern African Species Newly Distinguished from K. rotundifolia
The recent reinstatement of Kalanchoe decumbens Compton as well as the description of K. waterbergensis van Jaarsv. (Crassulaceae subfam. Kalanchooideae) necessitate a reassessment of the circumscription of K. rotundifolia (Haw.) Haw., thus far the morphologically most diverse kalanchoe indigenous to southern Africa. Material with bright green, generally orbicular to slightly obovate leaves that hitherto has been included in K. rotundifolia is here split off from the latter. The name K. klopperae Gideon F. Sm. & Figueiredo is published for this material.
