The specimens belonging to this one, gathered by me in South Siberia, constitute, in many respects, an intermediate form between the typical spe- cies Hierochloe odorata (L.) Wahlenb. and Hierochloe da- hiirica Trin. The culms are rather short, from 20 to 30 cm. high, slender, and glabrous. The leaves of the fertile shoots are from 1 to 2 cm. long, the sheaths rifled and very hairy (f. piibes- cens). The barren shoots have leaves, generally rising above the panicle. The leaves are smooth, the margins only being somewhat scabrous. The panic- le is short, lax, open, and broad, nearly ovate, the spikelets rather numerous, and the bran- ches of the panicle straightly spreading. The spikelets are small, oblong, or nearly circu- lar, from 2,5 to 4 mm. long. The glumes are broad, of unequal length, one of them generally only half enclosing the florets, the other one generally only slightly shorter than the florets, never projecting beyond them, membranous, with a green base, and generally furnished with one dorsal nerve only, lateral nerves wan- ting. At the summit more or less obtuse, never drawn out or pointed. The pales are of a shining brown, glabrous, or rarely sparingly pubescent but much fringed with long hairs. All the florets of the spikelet attain the same height. In point of the structure of the spikelets these specimens agree best with Hierochloe dahurica Trin, but, according to their considerable height their numerous spikelets, and
