17. A. lepida Hitehc. n. sp. Culms tufted, 1 to l 1 /^ feet high, erect, produc- 

 ing numerous short rhizomes ; ligule long, especially on the innovations, these 

 as much as 2 lines long, narrow, pointed ; blades mostly basal, firm, erect, flat 

 or folded, the upper culm leaf below the middle of the culm, the blade short, 

 an inch long or less ; panicle purple, erect, 4 to 6 inches long, the branches in 

 verticils, stiff and straight, becoming divaricately spreading, the lowermost 1 

 to 2 inches long, spikelet-bearing from about the middle, some short branches 

 intermixed; glumes l 1 /^ lines long* smooth or nearly so; lemma 1 line long, 

 awnless; palea wanting or a minute nerveless scale. (Caespitosa, 1-1% ped. 

 alta, recta, rhizomatibus numerosis brevibus ; folia firma, recta, omnia deorsum 

 infra culmi mediam aggregata, ligula producta, laminis 1 poll, vel brevioribus ; 

 panicula purpurascens, 4-6 pol. longa, ramis verticillatis, rigidis, patentibus; 

 glumae 1% lin. longae, glabrae vel subglabrae; lemma 1 lin. longum, muticum;

Type specimen collected in open gravelly woods, Siberian Pass, Sequoia 

 National Park, California, by A. S. Hitchcock, Sept. 6, 1908 (no. 3455 in the 

 National Herbarium). Other specimens referred to this species, all from Sequoia 

 National Park, are : dry rocky soil, south of Farewell Gap, Hitchcock 3401 ; in 

 mossy place, rim of Kern Canon, near Bench Mark 9839, specimens in somewhat 

 isolated bunches, Hitchcock 3434 ; dense masses in meadow, around lake, east of 

 Kern Canon, Hitchcock 3435. Differs from A. idahoensis in the larger spikelets, 

 from A. hiemalis var. geminata in the firm blades, and from all of this group, in 

 having rhizomes. 



18. A. longiligula Hitehc. Culms erect, about 2 feet high ; ligule 2y 2 to 3 

 lines long; panicle narrow, but loosely flowered, bronze-purple, 4 to 6 inches

 bearing at the middle a bent exserted awn ; palea minute.

25. GASTRIDIUM Beauv. 



Spikelets 1-flowered, in spike-like panicles. Glumes 2, enlarged or saccate at 

 base, much longer than the floret. Rachilla prolonged behind the palea. 

 Lemma pubescent, truncate, hyaline, awnless or bearing an awn just below the 

 apex. Palea narrow, about as long as the lemma. Cespitose annuals with flat 

 blades and pale shining panicles. Species 2, Mediterranean region. (Greek 

 gaster, belly, referring to the saccate glumes.) 



1. G. lendigerum Gaud. Culms about a foot high, smooth; panicle 2 to 3 

 inches long, dense and spike-like; glumes 1% lines long, gradually narrowed 

 into an awn-point ; lemma much shorter than the glumes, globular, pubescent 

 at apex, the awn 2% lines long, geniculate. 



Open ground and waste places, mostly in the Coast Ranges, at moderate alti- 

 tudes. Also in Oregon and Texas. Introduced from Europe.
