Abstract

Western Cameroon has one of the richest floras in Tropical Africa. This paper examines the subject of the phytogeographic delimitation of the area. The Cross River-Sanaga River interval is known to be of importance in primate geography. Is it also important for plants? The characteristics of the area may be more a product of the Cameroon Highlands than of the flora of lowland Guinea: more work is needed to decide this.

Abstract

The genus Allexis is known only from West and Central Africa (Jenik & Enti 1968). So far, only three species have been described (Melchior 1924). Revision of the Central African Violaceae (Achoundong 1997), and production of an account for Flore du Cameroun has revealed a fourth species, described here as Allexis zygomorpha. Further exploration of the littoral forest in Cameroon may yield yet more species in this genus.
