(Phyllanthaceae) were studied on the basis of foliar morphometric characters. The characters studied include leaf attachment, petiole features, laminar shape, apex and base shape including angles, margin type, blade class vein category etc. Estimation of vein islet number and minor venation details like the areole size, absolute vein islet and vein termination number were recorded and distinct description based on the leaf architectural traits for each species have been done. The quantitative data revealed some distinct variation among the species with some expressing close relatedness. A dichotomous key for the species have been constructed and relationships among the taxa have been represented through a dendrogram. Copyright@ International Science Community Association
