equal and numerous, the shorter floriferous to the base, the lower 
ones (about ¥% inch) nearly so;. spikelets about 1% lines long, 
empty glumes lanceolate, acute, membraneous on the margins; 
flowering glumes one-third shorter, oblong, obtuse, obscurely 
five-nerved; palet wanting; stamens three. 
Found by Mr. T. J. Howell on the sandy seashore in’ 
Oregon. It differs much from the ordinary form of A. exarata, 
and perhaps should be considered a distinct species. 
AGROSTIS FOLIOSA, V.—Culms 1% feet high, erect, J 
smooth; culm leaves four or five, erect, somewhat rigid, 4 to 6 
inches long, 1 % to 2 lines wide, long pointed ; ligule about 2 lines 
long, lacerate at apex; panicle 4 to 5 inches long, open and 
loose, the lower branches mostly in fives, unequal, the lower 
I inch long or more, somewhat spreading, capillary, rather few 
flowered, mostly naked below; spikelets little more than 1 line 
long, lanceolate, abruptly acute; flowering glume nearly as long 
as the outer ones, five-nerved, obtuse and shortly four or five- 
toothed at apex; palet wanting. Collected in Oregon by T. J. 
Howell. The panicle much like a short branched A. adba. 
AGROSTIS DIEGOENSIS, V.—Culms erect, stout, 2 to 3 
feet or more high, smooth; leaves 4 to 7 inches long, 1 to 2 
lines wide, erect, those of the culm with long sheaths (the upper 
ones 8 or g inches long); ligule about 2 lines long, acute; pan- 
icle 6 to 8 inches long, lanceolate, the joints rather distant (the 
‘lower 1% to 2 inches); branches numerous, unequal, erect, the 
longer ones about two inches long, and floriferous above the 
middle, the shorter floriferous to the base, the flowers numerous ; 
spikelets light green, 1% to 2 lines long, outer- glumes acute, 
scabrous on the keel; flowering glume one-third shorter, oblong, 
obtuse, the mid-nerve terminating about the middle, with or 
without a minute awn; palet none. Collected at San Diego, 
California, by C. R. Orcutt. The panicle resembles that of a: 
alba, but is narrower, stouter and more closely flowered. 
AGROSTIS OREGONENSIS, V.—Root fibrous (annual ?); 
culms about 2 feet high, somewhat slender, radical leaves fili- — 
form ; culm leaves distant, narrow, soon tapering to a long, slen- 
der point, 3 to 4 inches long; ligule short; panicle 4 to 5 inches 
long, nodding and flexuous, open but not spreading; branches
