Morpho-anatomical aspects of the epiderm in two species of Lathyrus
AbstractThe paper deals with the microscopic study of the leaves epiderm in Lathyrus latifolius L. and Lathyrus odoratus L. The transversal section through the foliar limb shows slight differences between the two faces of the limb and a weak development and differentiation of the mesophyll. The epidermic cells have rectangular or polygonal shapes, with undulated walls with great and medium amplitudes in Lathyrus latifolius and medium and small ones in Lathyrus odoratus. Stomata apparatus consists of two reniform cells, with two, three, seldom four epidermic cells. Lathyrus odoratus has the ranunculaceous anomocytic type of stomata and Lathirus latifolius presents both this type and the ranunculaceous hemiparacytic type.
