LEAF VENATION ARCHITECTURE IN SOME AMARANTHACEAE

摘要

In the present investigation, we have studied the leaf venation architecture (foliar venation characteristics) of eighteen taxa belonging to Amaranthaceae. The study suggests that that the following characters: major venation pattern, marginal venation, number of vein-lets per sq. mm, thickness of primary vein, number of 2° veins, nature of areole formation, highest vein order and terminal tracheids are quite helpful in the identification of the taxa belonging to plant family Amaranthaceae. Further, based on our detailed observations we hereby propose a key for the identification of taxa investigated.
