single, coming from ribs on the sulcate raehis, t!w Bpikelet* being 

 on flexuous but not colored and rather stout and short pedicels. 

 The floral scales are scabrous. The species of Crypsinna are: 



Crypsinna stricta (Presl) Fourn. 



Crypsinna macroura (1IHK.) Fourn. which is Crvpaig of 

 HBK. and Cinna Kunth. This differ* from rigena in thu long l»g- 

 ule. The oblong-lanceolate glume- are about •'» rum. long or morn 

 and longer than the lemma normally, though sometimes a little 

 shorter. The glumes are sometimes short— awned. 



Crypsinna rigens (Benth.). Epicampes rigens Benth. Journ. 

 Linn. Soc. 19 £8. This differs from the species described below in 

 the short and setaceous leaves, the pa?iicle i-i dm. long and rare- 

 ly over 5 mm. wide. The glumes are lanceolate to narrow!} ellip- 

 tical, acutish, f— | the lemma. 



Crypsinna setigulmis n. sp. 



Stems round, smooth, 4-8 mm. thick below, strict, 3-4 ft. h gh, 

 simple. Sheaths rather loose, coarse, rounded, the U|>per partly 

 inclosing the panicle, rather many. Ligule rigid, about 2-3 nun. 

 long, much wider than long, split. Leaves closely involute from 

 the first and about i mm. wide, rigid and thick, long-acuminate 

 and scabrous, about 2 ft. long, with age flattening out and becom- 

 ing 4-6 mm. wide Panicle 1-2 ft. long, acuminate, very compact, 

 about 1 cm. wide nearly white, the rays ami ped eels very short 

 and closely appres§ed. Glumes white and very thin, scabrous, sul 

 ulate as if awned, about equal, 7-8 mm. long Lemma linear- sub- 

 ulate, lead-colored, scabrous, the tip with 2 short and oblong, 

 white ears, rarely mucronate by a slight production of the midrib, 

 about .i mm. long, much shorter than the glumes and eloaely in- 

 vested by them, rigid. Palet about asRung as lemma and like it. 

 This seems to differ sufficiently from C. stricta. Marsh Lake Si- 

 erra Madre Mts. Chihuahua Mexico near Garcia in dry pine woods, 

 Middle Temperate Life Zone, Sept. 1 90-*. 



Crypsinna breviglumis n. sp. 



Much like the above in habit ana character except that the leave* 

 are about 3 ft. long, flat from the first and very coarse and thiek on 

 the lower third, the rest tardily involuh ami 1-2 mm. wide, in- 

 juring to a fine point. The panic e as in the l**t, but the glum 

 oval to ovate, about 2 mm. long and k-% the lemma, white, roun- 

 ded and very obtuse, a little erose, rarely ovate and with midrib 

 produced as a short macro or awn, the upper acute mtd :i Bit-tie 

 longer and slightly narrowed Lemma linear-lanceolate, firm, rath- 

 er dark above, acute, the lobes almo t non-, midrib prod lire : as 

 long mucro or short and straight awn. Glumes and lemma very » ca-
