It has no near relative among the North American species.

3. CALAMAG-ROSTIS LEMMONI Kearney, sp. n.- 



Plants with .slender, creeping rootstocks, numerous, short, erect, or ascendiLg innova- 

 tions, many slender erect culms 2.5 to 4.5 dm. high, anil dark purple panicles. 

 Culms often .slightly geniculate, with a few short, loose, thin, marcescent sheaths 

 at base ; internodes 2, finally much exceeding their sheaths, the uppermost nearly 

 twice as long as both sheath and blade. Sheaths loosely embracing the culm, 

 thin, glabrous. Ligule 2 to 4 mm. long, thin, whitish, nearly glabrous, lower 

 ones broadly truncate, upper ones narrowed from the base to the acute ajiex. 

 Blades 2 to 20 cm. long, 1 mm. or less wide, strongly involute, especially toward 

 the setaceous tip, somewhat spreading, flaccid, scabrous on the margins and 

 upper surface. Panicle 4 to 8 cm. long, 1 to 2 cm. wide, oblong-lanceolate, acu- 

 minate, contracted, loosely few-flowered, erect, often somewhat flesuous; raeliis 

 slender, somewhat flexuous, glabrous or very nearly so, dark purple, its lowest 

 internode 1.5 to 2 cm. long; branches spreading at a small angle (45 degrees or 

 less) to nearly erect, slender, somewhat flexuous, dark purple, glabrous or the 

 upper slightly hispidulous, secondary branches (usually) and shorter primary 

 branches (often) 1-flowered, lower primary branches in 3's to 5's, the longest 2 to 

 3 cm. long. Spikelets 4 to 5 mm. long. Empty glumes lanceolate to ovate- 

 lanceolate, acute or acntish, not strongly keeled, thin-membi-anous, dark red- 

 purple, sparsely and minutely scabrous on the keel toward apex or entirely 

 glabrous, equal or the flrst .slightly longer. Flowering glume considerably (often 

 nearly 1 mm.) shorter than the second empty glume (rarely nearly equaling it), 

 oblong-ovate, broadly truncate, thin-membranous, with hyaline edges and tips, 

 somewhat scabrous on the back, the nerves conspicuous, the lateral ones extended 

 into slender, unequal terminal awns 0.3 mm. long or less ; awn attached one-sixth

'In the descriptions of the species the following points are to be noted : Length of 

 innovation refers to length of branch and sheathes, excluding the blades. Number 

 of internodes of the culm refers to those of conspicuous length above the base and 

 below the inllorescense. Width of leaf-blade and of the panicle denotes the greatest 

 width. Shape of panicle refers to the outline in the dried plant, fresh material of 

 none of the species having been available. Length of spikelets means length of the 

 longest empty glume, and excludes the awn. The awn is described from dried mate- 

 rial, and does not, of course, exhibit exactly the same characters as in the fresh or 

 living state. 



In giving the geograi>hical range of the S])ecie8 the typical form alone is included, 

 that of the several varieties being separately stated. Data as to localities, altitude, 

 and latitude are taken for the most part from the collectors' labels, without attempt 

 at verifiejitiou.
