Abstract

Leaf architectural characters of 10 species of Terminalia (Combretaceae) were examined. The leaf architectural characters observed in the ten Philippine species of Terminalia were leaf attachment, petiole features, laminar shape, base and apex shape, margin type, blade class of the leaf, 2° and 3° vein category, spacing and angle. A dichotomous key to the 10 species of Terminalia was constructed and distinct description based on the leaf architectural characters for each species was done. Based on the result of this study the leaf architectural characters are of great help in plant taxonomy and systematics, most especially in dealing with sterile plant specimens.
