The leaf architecture of Malvaceae sensu APG was examined and characterized to determine if it can be used in classification of the family and the identification of its species. Forty species were observed, measured and described. A dichotomous key was constructed based solely on leaf architecture characters. Phenetic investigation using cluster analysis with the aid of PC-ORD ver. 4.14 program was later done. Results indicated that leaf architecture characters can be used in distinguishing some species of Malvaceae sensu APG. Cluster analysis showed heterogeneity of the clusters formed, thus, it supported the APG classification of Malvaceae as a family consisting of the four traditional families in the core Malvales namely Malvaceae, Tiliaceae, Bombacaceae and Sterculiaceae. It is recommended that specimens are collected personally instead on relying on available specimens in the herbarium. Preparation of leaf skeletons through clearing method can also be done in future studies. Increase of sample size is also recommended.
