Description of the leaf epiderm: On abaxial and axial sides of innovational leaves cells large. Cell walls comparatively thin, minutely sinuous, straightly decurrent. Costal zone of senile leaves 3-4-seriate. Costal zone with oblong parenchymatous cells alternating with twin-cells or merely with silica-bodies. Upper silica-body cubicoid, cork-cell oblong, hardly suberous, therefore staining yellowish green and not green with double vesuvine-malachite green staining. Intercostal zone 5-6seriate, but 10-seriate when one vein absent. Medial row with sporadic stomata. Parenchymatous cells large, elongate and medially slightly widening, alternating with minute macro-hairs, middle of zone with sporadic and long pili (as on the senile leaves of Koeleria mollis MANN). Costal zone on abaxial side of juvenile blades 3-6-seriate. Parenchymatous cells alternating partly with single cork-cells partly with twin-cells. Twin-cells longitudinally flattened, therefore silica-bodies transversely elongate, while cork-cells crescentic. Intercostal zone 3-5-seriate. Parenchymatous cells regularly oblong, cell walls strongly sinuous, sporadically alternating with stomata and regularly with minute macro-hairs ; pili of median row comparatively short, hence leaf glabrescent. Stomata developing mostly on axial side, 60 /< (Pl. IV, Figs. 1-2). Specimina examinata: Altera exemplaria Herbarium Florae Rossicae a Museo Botanico Academ. Imper. Sc. Petropolitanae editum. 2000.
