villous nodes, the upper shorter than the internodes ; ligules reduced 
to a dense fringe of short hairs ; blades linear-lanceolate from a 
rounded base, acute, 1-2J in. by 1-2J lin., flat or involute, rather 
rigid, pale green, hairy or quite glabrous, margins very scabrid, 
nerves numerous, fine and close, midrib and primary laterals hardly 
differentiated. Inflorescence secund or subsecund, very narrow, 
1-3 in. long, of 2-10 secund spike-like racemes, usually appressed 
to the filiform scabrid common axis, which is terete below and 
flattened upwards and scaberulous along the angles. Racemes 
simple, dense, J-l in. long ; rhachis filiform, triquetrous, J-y lin. 
wide, straight or slightly wavy, scabrid or ciliate ; pedicels solitary, 
very short, tightly appressed to the rhachis, relatively stout, scabrid 
or finely setulose, with thickened marginate tips. Spikelets 2- 
seriate, distant \ lin. or slightly more and therefore imbricate, oblong, 
subacute or obtuse, flat on the back, 1-1J lin. long, pallid with 
purplish tips, softly pubescent. Glumes very unequal, the lower 
usually reduced to a nerveless hyaline truncate scale, J lin. long, 
rarely \ lin. long and 1-nerved ; upper membranous, corresponding 
in outline and size to the spikelet, 5-nerved, minutely hairy. Lower 
floret neuter or more rarely £ : valve very similar to the upper 
glume, very faintly 5-nerved ; valvule very obtuse, subequal to 
the valve in shorter in neuter florets. Upper floret elliptic- 
oblong, obtuse, |-f lin. long : valve and valvule thinly crust aceous, 
shining, whitish or at length brownish, finely granulate. Anthers 
J lin. long. Grain oblong-elliptic or obovate-oblong, J-| lin. long, 
more or less flattened on both sides, but mainly on the back, olive- 
green ; scutellum more than half the length of the grain. — B. eruci-
