almost suppressed (hence lowest branches subopposite), the following 
about 4-3 lin. long ; branches solitary, loosely divided from some 
distance (up to 8 lin.) above the base, the longest two-thirds to three- 
quarters the length of the panicle ; lowest secondary branchlets 
rarely over 6 lin. long, often much shorter, like the others bearing 
few scattered or more or less approximate spikelets ; pedicels J-2 lin. 
long, tips minutely subdiscoid. Spikelets ovate-oblong to oblong 
in outline, acute, slightly over 1 lin. long, variegated or deep purple, 
glabrous. Glumes similar, lanceolate in profile, acute, thinly mem- 
branous, finely but very prominently nerved ; lower narrower, 
four-fifths the length of the spikelet, finely 3-nerved ; upper as long 
as the spikelet, boldly 7-nerved. Lower floret : valve very 
similar to the upper glume but somewhat shorter and often less acute ; 
valvule slightly shorter, oblong, acute ; anthers f lin. long. Upper 
floret oblong, acute or subacute, almost as long as the lower, 
yellowish or whitish, polished ; valve and valvule thinly coriaceous.—

Annual, growing in loosely tufted clumps, 3-6 in. high. Culms 
geniculately ascending, filiform, very weak, branched from most 
nodes with the lower branches interlacing and the upper short, but 
all ultimately flowering, terete or subangular, prominently striate, 
smooth and glabrous, nodes mostly exserted. Leaf-sheaths some- 
what loose, subherbaceous, finely striate, softly hairy ; ligule 
reduced to a fine ciliate membranous rim ; blades lanceolate to 
lanceolate-linear from a gradually rounded and constricted base, 
acute, J to over 1 in. by less than 1 to 3J lin., flat, thin and soft, 
spreading more or less horizontally, loosely and softly hairy all over, 
midrib and primary lateral nerves (2 or 1 on each side) very fine or 
hardly differentiated, cross-veins none. Panicles exserted, or at 
least the lateral enclosed with their base in the supporting sheath, 
erect, broad-ovate in outline, from less than \ to over 1 in. long and 
wide, rigidly open and loose, divided up to the third or fourth degree ;
