The specimens collected are characteristic in having the stems vigorous, to '- m. 

 high, glabrous, moreover in ha\ing the leaves rather broad. 4 — 6 mm., completely 

 glabrous, even the orifices of the sheats being destitute of tufts of hairs. The flower 

 cluster is made up of numerous, small, globular, and few-flowered spikes, 10 to 15 in 

 number, on stiff, erect peduncles, to 5 cm. long. The lowest iiract foliose, equalling or 

 even exceeding the inflorescence. The capsule is of the same length as the perianth.

 I have also observed the species near Ust Sisli-kem and at Ust Kamsara.
