Abstract

A morphometric study was performed on six Berlinia species of the Nigerian flora. Individual specimens deposited at Forest Herbarium Ibadan and University of Ibadan Herbarium formed the units of study.  Twenty morphological characters were assessed and analyzed following conventional taxonomic practice. Results showed a close resemblance between B. craibiana and B. grandiflora, which share affinity with B. bracteosa and B. confusa, while B. coriacea appears to be distantly related.  Species distribution studies revealed that B. grandiflora exists in savanna and forest regions while other members of the genus are found only in forest zones. While suggesting practical measures for conserving endangered Nigerian flora, we also recommend that further taxonomic studies be carried out on the genus Berlinia and its related allies to ascertain their placement within the Caesalpiniodeae.
