Dialium guineense and Detarium microcarpum are tropical trees with medicinal features and economic value in Nigeria. Both are traditionally used in Nigeria for the treatment of malarial fever, typhoid, and many other ailments. Despite the economic value of D. guineense and D. microcarpum no taxonomical information available. The study aimed at establishing taxonomic biomarkers through morphological, anatomical, and unsupervised multivariate analysis. The morphological study was determined macroscopically, anatomy using fast green/ safranin and unsupervised Multivariate analysis using SIMCA. Leaf of D. guineense range between 4-11 cm length and width 3-5 cm while that of D. microcarpum range between 13-21 cm and width 4-8 cm, respectively. The numerical study showed variation between the species. Clear discrimination was established from the vascular bundle at midrib and the presence of trichome in D. microcarpum at both the midrib and lamina transverse sections. Multivariate analysis show despite their differences in morphological and anatomical established a strong relationship. Therefore, the study concluded the vascular bundle at the midrib are taxonomic biomarker for identification of the D. guineense and D. microcarpum. The obtained results will serve as scientific bases for drug exploration from the species in Nigeria.
