Abstract: A new Annonaceae species, Dasymaschalon leilamericanum is described from Mount Lantoy Key Biodiversity Area (KBA) in the Municipality of Argao, Cebu, Philippines. D. leilamericanum is distinguished from closely related species by morphological characters including laminar size, leaf areolation, and seed/fruit shape and size. Significant differences observed in a multivariate analysis of morphological data for D. leilamericanum, D. clusiflorum, D. filipes, D. ellipticum, and D. blumei indicate D. leilamericanum is a distinct species. A phylogenetic tree analysis performed using maturase K (matK) and ribulose 1,5-biphosphate carboxylase (rbcL) as molecular markers failed to match D. leilamericanum with other Dasymaschalon species. Taken together, the results of morphological and molecular analysis indicate a unique evolutionary pathway for D. leilamericanum with its genus.
