Leaves morphology in Madhuca Buch. - Ham. ex J. F. Gmelin (Sapotaceae) and its taxonomic significance

N. OMAR, A. LATIFF

Abstract


Leaf morphology of Madhuca Buch. was examined to assess its taxonomic significance. A total of about 900 specimens collected in Peninsular Malaysia lodged in the herbaria were studied and 30 taxa were recognized. Two major groups of species were recognized on the basis of the secondary veins of the leaves. The first group is characterized by the secondary veins that joined at the tips either archingly or inarchingly forming the intramarginal vein and the second group is characterized by those species that show their secondary veins diminish until they become inconspicuous at the margins. The leaves morphology observed also include shape, size, apex, base, midrib, texture, colour, secondary and tertiary nervation and petioles characters.
