 248. 

 Culm stout, three to four feet high, triquetrous, scabrous : leaves 

 rigid, carinate, equalling the culm : bracts purple at the base, the 

 lowest two or three feet long and short-sheathed, the upper ones 

 becoming scale-like: peduncles three to six inches long, scabrous: 

 spikes dark purple, lax, the uppermost subsessile and single and often 

 crowded, the middle ones fasciculate with two or three from a sheath, 

 the lowest compound, long-exserted, and nutant: spikelets half an 

 inch to three inches long and one to four lines broad: perigynium 

 lanceolate (two and a half lines or less long and nearly a half-line 

 broad) or lance-oval, glabrous, nerved, dark purple, produced into a 

 cylindrical bidentate and ciliate-mouthed beak, about equal to the 

 lanceolate and raucronate purple white-margined scale. Variable. — 

 Peak of Orizaba, South Mexico, at 12,500 feet, Galeotti, Linden. 

 Colombia and Ecuador. 



B. Indices, Tuckerman, 1. c. Peduncles all branched (simple in C. Schiedeana), 

 the spikelets short and surrounded at the base by a spathella or modified 

 perigynium; perigynium small, mostly excurved. — Curious species with 

 the aspect of grasses, very poorly represented in the New World.

 C. polysfac/iya, var. minor, Boott, 111. 157. 

 Boeckeler, in Linna^a, xl. 362, cites under 0. cladostachya the text 

 and figures of Boott made as G. polystachya (111. 152, tt. 490-492), 

 but I find no reason for so doing. Boott admits that he does not 

 know the distinctions between G. cladostachya and G. polystachya, and 

 I am not able from either his description or figures to tell which 

 species he had. — Culm very slender, one to two feet high, equalled 

 by the very flaccid and rough-margined leaves : spikelets green, 

 scattered and loosely spreading, a fourth inch or less in length : 

 perigynium elliptic, triquetrous, small (one and three fourths lines 

 long, one half-line broad), conspicuously nerved, smooth, produced into 

 a very slender bidentate beak, twice longer than the ovate mucro- 

 nate scale. — South Mexico: Valley of Cordova and near Orizaba, 

 Bourgeau, Orizaba, Botteri, Mirador, Liehnann, Jalapa, Schiede, 

 Vera Cruz, Linden ; Guatemala, near city of Guatemala, Hartweg, 

 Bafios de los Padres, Bernoulli ; Costa Rica, Hoffman ; Jamaica, 

 Swartz. Colombia.
