V 26. A. pseudapricus, Stapf. Annual, rarely perennial, with a few 
intravaginal innovations, usually 2-4 ft. high, occasionally much 
higher. Culms slender, erect, simple except for the inflorescence 
or with a long branch resembling the primary culm from one of the 
upper nodes, up to over 6-noded below the panicle, terete, glabrous, 
smooth. Leaf-sheaths terete, tight, striate, often flushed with 
purple below, glabrous, rarely loosely hairy, smooth, produced at 
the mouth into short auricles ; ligules scarious, truncate, adnate 
to the auricles of the sheath, up to 1 lin. (rarely more) long ; blades 
linear from a narrow base, long-tapering to a setaceous point, up to 
over \ (sometimes ,1) ft. long, 1-1J (rarely 2J) lin. wide, rather firm, 
but flexuous, glabrous or sparingly hairy, pale green, turning reddish, 
scaberulous, particularly upwards, midrib slender, whitish, primary 
lateral nerves 2-3 on each side, very fine. Inflorescence an elongate 
or fastigiate obpyramidal and often ample spatheate panicle, J-1J ft. 
long, of 5-7 frequently mixed tiers, approximate upwards and up to 5- 
(rarely 7-) rayed ; lowest spathes like the preceding leaves, but with 
shorter, almost setaceous blades, the following rapidly approaching 
the spatheoles in shape and size ; rays slender, filiform, those of 
mixed tiers usually very unequal, the compound ones often over- 
topping the next or 2 next tiers, the simple f to over 1J in. long. 
Spatheoles more or less scarious, linear-lanceolate, long-tapering 
upwards, acute to setaceously acuminate, glabrous or nearly ap- 
pressedly hairy, 2-2 J (rarely 3) in. long and at length tightly in- 
rolled ; peduncles finely filiform, at length slightly (rarely much) 
exceeding the spatheole or permanently shorter than it, puberulous or 
scaberulous towards the subcupular tips. Racemes 2-nate, one 
subsessile, the other with a short base, from less than 1 to 2J 
in. long, flexuous, villous, mostly laterally exserted from the spathe, 
at least before maturity ; joints and pedicels clavate-cuneate, 
attenuated to a very slender base, tips very obliquely truncate, 
obscurely hollowed out, the pedicels often unequally 2-toothed, 
margins silky-ciliate, upper cilia up to 1-|- (rarely 2) lin. long. Ses- 
sile spikelets of all pairs heterogamous (or those of the subsessile 
more or less imperfect), laterally much compressed, loosely wedged 
in between joint and pedicel, narrowly linear in front view, 2-|-2f 
lin. long, pale yellowish-green ; callus slender, subacute, i lin. long, 
shortly and densely bearded. Glumes equal, lower chartaceous 
along the keels, otherwise membranous, deeply and narrowly grooved 
between the narrow keels which are smooth below and scaberulous 
near the tips, minutely truncate, glabrous or very sparingly and
