cilia) from tubercled bases, lateral nerves 3-5 on each side, like the 
midrib very fine. Racemes 4-5, fascicled, l|-2 in. long, slender, 
flexuous, villous, pale green, silvery, the fascicles borne on a common 
peduncle, usually exserted from the supporting sheath. Rhachis 
fragile ; joints very slender, about 1J lin. long, densely hairy, hairs 
up to lin. long ; pedicels similar to the joints. Sessile spikelet 
linear-lanceolate, acuminate, 2J-3J lin. long, including the short 
bearded callus. Glumes equal ; lower membranous-chartaceous, 
gradually passing into a short and very fine hyaline point, very 
convex on the back, muriculate along the 9 green slender nerves ; 
upper glume narrowly linear-lanceolate in profile, setaceously 
acuminate, membranous, 3-nerved, minutely and spinulously ciliate 
on the outer nerves. Lower floret reduced to a linear-oblong 
hyaline nerveless valve, 1J-2 lin. long. Upper floret obliquely linear 
in profile, acute, hyaline, 2 lin. long, very faintly 2-nerved, awned 
from near the base, awn 8 lin. long, very fine, kneed and twisted 
below the middle, blackish. Stamens 2 ; anthers J lin. long. Pedi- 
celled spikelet reduced to a linear-lanceolate 3-nerved glume, 1-1 J 
lin. long.— Hack, in DC. Monogr. Phan. vi. 353, excl. var. micans ;

very slender, ascending from a more or less prostrate, much-branched 
and rooting base, 2-8 in. high, smooth, glabrous, with 2-4-nate 
flowering branches above, internodes mostly exserted. Leaf-sheaths 
I lax, the uppermost slightly inflated and bladeless, glabrous except 
the bearded nodes and the sometimes hairy upper margins ; ligules 
membranous, short, ciliate ; blades oblong-lanceolate, from a cordate 
and amplexicaul base, finely acuminate, \ to slightly over 1 in. long, 
3-4 lin. wide, flaccid, more or less softly hairy on both sides, ciliate 
towards the base ; primary lateral nerves 2-3 on each side, very fine, 
Racemes few or up to 9, in fascicles, borne on filiform ultimately long 
exserted peduncles, J-| in. long, very slender, flexuous. Rhachis 
fragile ; joints J lin. long, filiform, ciliate, the uppermost cilia up to 
1 lin. long, or the lower joints glabrous or nearly so ; pedicels (if 
present) like the joints, but shorter. Spikelets usually solitary, 
without a trace of a pedicel, or sometimes paired (1 sessile, the other 
pedicelled) in the upper part of the raceme. Sessile spikelet linear- 
lanceolate, laterally compressed, including the very minute puberu- 
lous callus, 1-1 J lin. long. Glumes subequal ; lower membranous, 
acute or very minutely 2-toothed, scaberulous along the faint 5-7 
nerves or almost smooth in the lower part ; upper glume linear in 
profile, produced into a fine short bristle, slightly exceeding the 
lower glume, faintly 3-nerved. Lower floret reduced to an oblong or 
lanceolate nerveless hyaline valve, about \ lin. long. Upper floret § ;
