3- or indistinctly 5-nerved, somewhat exceeding the 3-nerved upper one; floral glume 
3 to 34 lines long, brownish when ripe, pubescent with appressed hairs, especially 
below ; callus short, acute, the apex with a short, distinct crown of hairs; awn 14 
inches long, twice bent and plumose to the upper geniculation, with rather coarse 
hairs, less than a line long below and shorter above; palet one-fourth shorter than 
floral glume; anthers naked, 
The above is essentially Prof. Thurber’s description, and answers well to a portion 
of the specimens in the Nat. Herb., under that name; others so named have short 
inconspicuous ligules, and belong to the next species. 
5. S. stricta Vasey. Bull. Torr, Club, x. p. 42. Culms tufted, 1 to 14 feet high, 
erect; lower leaves 6 inches long, narrow, with leng setaceous points, the upper 
shorter, the uppermost sheathing the base of the panicle: ligule very short and indis. 
tinct; panicle 4 to 8 inches long, strict, erect, the lower branches in twos or threes, 
1 to 2 inches long, appressed, flowering to the base; outer glumes narrowly lance- 
olate, acuminate, 3-nerved, thin, 5 lines long; flowering glume about 3 lines long, 
including ths acute stipe, sparsely pubescent all over; awn 1 to 1} inches long,

Var. SPARSIFLORA. Leaves involute-filiform, shorter than in the type, the panicle 
thinner and fewer-flowered, the awn less pubescent.—California (Bolander, No. 5038 
and 5020), Oregon (Cusick) and Washington (Suksdorf). 
B. Panicle more open; branches erect. 
6. S. Stillmani Bolander. (Bot, Cal, 1. p. 287,) Culms tufted, stout, 3 to 5 feet 
high, genicu.ate below, smooth, except the pubescent nodes: radical leaves 12 to 
18 inches loag, those of the culm (4 or 5) much shorter, all glaucous, involute, at 
least at the long-attenuated apex, the lower 3 to 4 lines wide at the base, mostly 
smooth below, scabrous above and on the margins; ligule minute; sheaths loose, 
shorter than the internodes, striate, smooth, slightly bearded at the throat; pani- 
cle 5 to 10 inches long, narrow and spike-like, interrupted below, nearly white and 
lustrous, the axis puberulent with an incomplete pilose ring at the nodes; rays crowded 
and fasciculate, more or less united below, 1- to few-flowered; glumes nearly equal, 
about 9 lines long, acuminately bristle-pointed, membranaceous-hyaline, the lower 
3, the upper more or less 5-nerved at base; floret 5 lines long, with a short, one- 
sided, white, hairy callus; lower palet herbaceo-chartaceous, distinctly 3-nerved, 
sparsely pubescent throughout, the divisions of the two-cleft tip nearly a line long; 
upper palet similar; awn inserted below the tip of the palet, 12 to 15 lines long, 
tortuous, slightly bent above the middle, scabrous; stamens 3; anthers long, mu- 
cronulate.—Southern California. 
7. S. coronata Thurb. Bot. Cal. 11. p. 287. Culm 4 to 6 feet high, 3 or 4 lines 
thick at base, where it is clothed with the reinains of old sheaths; lower culm leaves 
about 38 feet long, 4 to 6 lines wide at base, gradually attenuated to a long involute 
point, the uppermost about 6 inches long, almost filiform and rigid, all slightly 
scabrous on both surfaces and margins; ligule very short, lacerate-fringed ; sheaths 
somewhat loose, the uppermost much dilated, striate, smooth, except the margins, 
these mostly ciliate, especially at the throat; panicle 12 to 16 inches long, at first 
spike-like and included for one-third or one-half its length, at length exserted and 
loose, but narrow, with erect branches; lower rays in pairs or threes, long and tlower- 
bearing above, the upper in fascicled clusters and tlower-bearing to the base; spike- 
lets short-pecdiceled, pale-greenish becoming purplish; glumes unequal, the 3-nerved 
lower about 8 lines, and the 5-nerved upper, 6 lines long, both acuminate and some- 
what bristle pointed, slightly scabrous on the nerves; floret, including the brief 
curved callus and long hairy crown, 5 lines long; lower palet scarcely chartaceous, 
bifid, with delicate hyaline teeth less than a line long, clothed with silky, shining 
hairs, those below about a line long, the upper more numerous, forming a dense tufted
