Abstract
The present paper embodies a detailed account of the morphological features of Glandulataenia pantii, a new species of the leaf genus Glandulataenia Pant. It differs from the two earlier described species of Glandulataenia, G. glandulata and G. triassicus in a number of features. Glandulataenia pantii leaf is comparatively smaller in size and narrower in width and has a higher concentration of lateral veins per centimetre. The midrib is distinct and narrower than those of the earlier described species and is persistent up to apex. Between the lateral veins, are dark coloured circular glands, whose frequency varies in basal, middle and apical regions of the leaf. Leaves are amphistomatic, stomata usually restricted to areas in between lateral veins and on the midrib as well as lateral veins. Stomata haplocheilic, irregular to transverse in orientation. Guard cells sunken, each with 4 to 6 undifferentiated subsidiary cells. Cells over midrib elongated, rectangular, narrow usually thin, straight walled. Cells of lamina thin, sinuous walled.
