1. _Intermedium_ A. A. Eaton. Stems 1 to 4 feet high, 1 to 4 lines in diameter, simple or ultimately branched, 20 to 30 angled, rough with transverse bands of silex or becoming smoother by a later deposit covering them; sheaths longer than broad, ampliated, green excepting narrow black and white incurved limb, or exceptionally with other black and white markings; leaves keeled below the middle, flat and often centrally grooved above; teeth thin, brown, hyaline-bordered, deciduous or persistent; anatomy of _hiemale_ as previously described. New York, Michigan and westward. Common west of the Mississippi, being an important forage crop in some States. The anomalous _laevigatum_ collected by Rydberg at Thedford, Neb., No. 1283 (Cont. Nat. Herb. III, 194), is this variety, as is the plant referred to under the name of _variegatum_ by V. K. Chestnut (Cont. Nat. Herb. VII, 304), as used for various unimportant purposes by the Indians of Mendocino County, California. He also mentions the fact that horses eat it even when grass is abundant. 2. _Texanum_ Milde. Stems erect, very slender, somewhat rough, 10 to 12 angled, hardly 1 foot high, dirty green; sheaths elongated, slightly widened, 2 to 2 1-3 lines long and 1 1-3 wide, concolorous, leaves flat, centrally grooved and 4 angled above and centrally ridged below; teeth persistent, flexuous, white with red-brown center, lance subulate, smooth, only the lowermost three sheaths red-brown; ridges convex; carinal bast 7, vallecular 4, cells high, vallecular holes transverse oval; stomata rows separated by 7 to 8 cells, grooves naked, lumen of epidermal cells very wide, angles with broad, short bands, never with two rows of tubercles. Texas, _Chas. Wright_. This is Milde’s description. I have never seen this plant. Milde states that it is a very peculiar plant that equals the weakest specimens of var. _Moorei_, but differs greatly from it, and he asks if it may not be the young stage of a larger species.
