Studies in the Justicia and Siphonoglossa (Acanthaceae) species of southern Africa: final conclusions

Abstract

On the basis of seed surface micromorphology, pollen and inflorescence type, as well as characters of the capsule, seven sections can be distinguished in the southern African species of Justicia. The relationship of these to the sections recognised by Graham is discussed. A key to the sections and a synopsis of their main distinguishing characters are presented. One new section, sect. Minima lmmelman, is described. A short note on the generic position of the Siphonoglossa species of the region, following on from a previous paper, is also given.
