Plant 1-4 cm. high, the stems erect or spreading; radical leaf 
with blade 5-20 mm. long, its sheath 2-5 mm. long; lowest leaf 
of the inflorescence 10 mm. or less in length; spike 1, rarely 2, 
broadly ovate in outline, 3-4 mm. long, squarrose or even hystri- 
cine; scales about 2 mm. long, narrowly lanceolate, the narrow, 
hyaline margins barely brownish, tapering gradually into the long, 
spreading awn; achenium brown, its form and surface as in the 
type form of Hemicarpha micrantha. 
This species exhibits no tendency toward intergradation with 
#1. micrantha, and is readily distinguishable from that plant by its 
broad, bristly spikes, and narrow, long-awned scales. Specimens 
have been examined by the writer from the type locality, and from 
Falcon Valley, in the State of Washington.

PANICULARIA LAXA sp. nov. 
A coarse leafy grass, 2-4 ft. high, with a diffuse ample panicle 
and oblong, somewhat turgid spikelets. Sheaths scabrous, the 
lower exceeding the internodes. Ligule about 1 line long, thin, 
lacerate. Leaves 8-15 in. long, 3-4 lines wide, very rough-sca- 
brous both sides tapering to a sharp point or the lower ones 
abruptly sharp-pointed. Panicle 7-9 in. long, the main axis and 
branches strongly scabrous, lower branches in 2s or 3s the upper 
Solitary, the longer and usually widely spreading lower ones 3-5 
in. long. Spikelets oblong or broadly ovate, 3—-5-flowered, about 
2 lines long, much exceeding the pedicels, and from 1-1 % lines 
wide. Empty glumes unequal, scarious-margined, the larger 
Second glume about 1% the length of the first floret. Flowering _ 
glumes rounded on the back, 1-1 l{ lines long, broadly obovate, 
obtuse, with a narrow scarious margin above, 7-nerved, nerves not 
Prominent. Palea nearly equalling the glume, the keels smooth, 
strongly curved above. 
Closely allied to P. Canadensis, but the smaller spikelets are 
gteen or purple-tinged, and the more obtuse floral glume scarcely 
exceeds the narrower palea. a
