very short ; seeds 4™™ long, brown, lanceolate, grooved on one 
side. 
In habit this plant resembles /. microstachya Nutt. from which it is 
separated by its dense evenly ciliate lower palet, and from F. microstachya 
ciliata Gray by its glabrous glumes. This species (number 2196) was col- 
lected by Professor LZ. F. Henderson at Nort akima, Yakima county, 
Washington, May, 1892. Type specimen is in my herbarium. 
Festuca idahoensis, n. sp. Apparently a perennial, from 
creeping rootstocks. Culms striate, shining, 7-9 high, 
2—3-jointed. Cauline leaves few, filiform, those of the sterile 
shoots equaling or exceeding the culms, striate, glabrous beneath, 
involute, less than 0.5 ™™ in diameter, canescent inside ; sheaths 
loose, striate, smooth, the throat abruptly constricted at the leaf 
base ; ligule a brown narrow fimbriate band. Panicle ovate, 
7-12 long; rays 2, spikelet-bearing from below the middle ; 
spikelets few, loosely 3—4-flowered, 10™™ or less long; glumes 
glabrous, broad, 3-nerved, upper 4™™ long and obtuse, lower 
acute, 3™" long; lower palet broadly lanceolate, obscurely 
5-nerved, 6™™ long, bearing a scabrous awn 3™™ long; upper 
palet equal in length, quite broad, 2-nerved, slightly bidentate 
at the apex ; each of the 3 anthers 3™™" long; styles 2, distinct, 
upon the obovoid ovary. 
This fescue grass is distinguished from F. rubra L., which it resembles, 
by its extremely long filiform leaves. It was collected by Mr. L. R. Abrams, 
in Smith’s Valley, Shoshone county, Idaho, July, 1900. Type specimen 
(number 688) is in Mr. Abrams’ herbarium. 
Bromus magnificus, n. sp.——A _ scattering perennial, with 
creeping rootstocks, bearing few slender woolly fibrous roots. 
Culms 1-3™ tall, shining, erect, with 6-9 densely pubescent 
joints. Blades flat, scabrous on the edges, 7™™" wide, the larger 
ones 3" long, upper surface puberulent with few bristle-like hairs, 
lower surface glabrous, apex acuminate ; sheaths soft, equaling 
the internodes, conspicuously striate, entirely covered with long 
soft retrorse hairs ; ligule brownish, 2™™ long. Panicle not 
drooping, pyramidal in outline, 25 ™ long, nearly the same 
in diameter at the base ; rays 2-3, long and slender, subtended 
by a circle of fine hairs, pendulously flexuose, 1I—2-branched 
from the middle, scabrous near the distal ends; spikelets soft,
