EPIDERMAL STRUCTURE AND DEVELOPMENT OF STOMATA IN <i>EPHEDRA FOLIATA</i> BOISS.

Abstract

S ummary The epidermal structure of the leaf and stem of Ephedra foliata Boiss. is described. The epidermis of internodes and leaves shows longitudinal rows of cells and stomata. In the nodes and the leaf bases the stomata are irregularly orientated. The subsidiary cells are perigene and the development of stomata is typically haplocheilic.
