Scattered in dry meadows and in thickets on the islets in the rivers Yenisei and 

 Abakan, in dry brush-wood at Kushabar, near Ust Algiac, at Ust Sisti-kem and Ust 

 Tara-kem. The specimens gathered are distinguished by completely glabrous sheaths. 

 The lower panicle-branches are comparatively long and spreading, thus giving the 

 panicle a pyramidical appearance. The glumes are generally furnished with rather long, 

 stiff hairs along the keel and the margin, whereby the specimens somewhat approach

Rather common in the regions explored, along road-sides, in court-yards, etc., in 

 settlements, and camps of gold-diggers in the Amyl taiga, where occurring in a multitude 

 of different forms. A form with spikelets of a deep green occurring near Kushabar (f. 

 viridis Leijeune ct Courtois, Comp. Fl. Belg. I (1828) p. 80), and another one with 

 broad, to 5 or 6 mm. broad leaves, in the Amyl taiga (f. latifolia).
