Abstract
Clerodendrum L. s.l. (formerly Verbenaceae) is a large pan tropical-genus, comprising ca. 400 morphologically diverse species. Delimitation and subdivision of the genus based on morphological studies have been problematic. Parsimony analysis of cpDNA restriciton site data shows that Clerodendrum s.l. is polyphyletic. This polyphyly is confirmed by separate analyses of (1) chloroplast ndhF sequences and (2) nuclear ITS sequences. Subgenus Cyclonema and section Konocalyx (subgenus Clerodendrum pro parte) are monophyletic and emerge as a lineage distinct from the rest of Clerodendrum. Cyclonema (Hochst.) should be reinstated as a genus, the delimitation of which should include section Konocalyx. Clerodendrum s.s. comprises three discrete clades, two of which correspond to biogeography: African species and Asian species. The third clade contains coastal species from Africa, Asia and central America. These results have important implications for the subdivision of Clerodendrum s.s. and indicate the need for a thorough morphological revision of the genus
