Description of the leaf epiderm: On the abaxial and axial sides of the innovational leaves the cells are comparatively small. Senile blades with weakly developed 2—4-seriate costal zone; parenchymatous cells elongate, parallel and thinwalled, finely sinuous, regularly alternating with definitely cubic silica-bodies, also their walls thin and weakly sinuous. Intercostal zone 4—5-seriate, the rows wider than in costal zone ; in rows without macrohairs or stomatal cells the parenchymatous cells are strongly elongate, regularly alternating with primordia of minute macrohairs, rarely with elongate macrohairs. Lowest blades also with long pili in middle row (as on the senile leaves of Koeleria albescens DC.) ; costal zone of juvenile blades more developed, 3—5-seriate, elongate or shorter parenchymatous cells regularly alternating with silica-bodies; both kinds of cells narrow, their walls straight and thin, very finely sinuous. Some silica-bodies occasionally absent, then silica-bodies rarer at meeting of two parenchymatous cells. Intercostal zone generally 5-seriate. Along margin of zone greatly elongated parenchymatous cells appearing singly, not alternating with primodia of minute macrohairs, in all other rows parenchymatous cells alternating with small primordia of macrohairs and very sparsely with stomatal cells ; zone medially without macrohairs (Plate V Fig. 2—3). Stomal cells 36 p. A gracile and loosely cespitose plant with many culms and slightly stoloniferous, caused mainly by the extravaginal innovation. Rhizome also recumbent, slightly elongated, nearly repent, about 3 cm long and 4 mm thick. (This is based naturally on the herbarial sheet, because the specimen —• though carefully collected —- can only be a part of the tuft. What is without doubt is that the rhizome is slightly elongated, indeed somewhat creeping). Paniculate shoots growing one after the other from the recumbent rhizome. Vetust vaginae pallid, partly lacerated. (However, the mycelial tufts, evincing their decaying activity, can be discerned also in this plant). Vetust vaginae 3,5 cm long Stature 35—36 cm. Senile blades 10—15
