- Title
A reassessment of Hemizygia and Syncolostemon (Ocimeae-Lamiaceae).

- Abstract
The relationships between Hemizygia and Syncolostemon are investigated. Parsimony analyses of morphological data and sequences of the trnL intron, trnL-trnF intergenic spacer and the rps16 intron were carried out separately and in combination. All analyses largely show strong support for the two genera as a monophyletic group; neither genus as currently circumscribed is monophyletic. They are herein merged under the earliest name Syncolostemon. The dade can be diagnosed by the presence of fused anterior stamens. Bremer's ancestral area analysis method suggests that the Afroalpine and Afromontane archipelago-like Regional Centre of Endemism may be the ancestral area for Syncolostemon s.l.
