Discussion:
Supplement: The specimens cited or described in this supplement were received after the publication of Parts I and II. Aphelandra atecmarta in the key would follow A. crenata, but it differs in having entire instead of crenate leaves. The spikes of A. crenata , too, are shorter and more compact.
