Abstract

The results of comparative analysis of localization and orientation of conductive bundles in the leaf blade of representatives of Dracaena Vand. ex L. genus are reported. On the bases of investigated anatomical peculiarities of leaf blade of species studied was suggested that equifaciality of the leaf is ancestral feature of Dracaena genus.
