26. P. hystrix, Steud. Syn. PI. Glum. i. 95. Annual (? ■ — base 
unknown), up to over 1 ft. high. Culms erect or slightly geniculate, 
sparingly branched, all the branches flowering, slender, terete, up 
to 5-noded, nodes exserted. Leaf-sheaths tight or the lower loose,, 
rather thin, glabrous or ciliolate towards the mouth ; ligules up to 
| lin. long, hyaline, truncate, ciliolate ; blades linear from an equally 
wide base, long-tapering to an acute point, 1-3 by 1-1 J lin., flat,, 
flaccid, green, loosely hairy, more or less rough above and along the 
margins, midrib very slender, primary lateral nerves 2-3 on each side,, 
differentiated below. Panicle erect, more or less ovoid, open and loose, 
up to 4 in. by 3 in., divided to the third or fourth degree ; common 
axis filiform, terete, smooth, lowest internodes up to 5-9 lin. long ; 
lower primary branches divided from the base, but not forming false 
whorls, finely filiform, obliquely erect, flexuous, smooth, the longest 
two-thirds to three-quarters the length of the panicle ; ultimate 
divisions capillary, spreading, flexuous or wavy ; pedicels unequal, 
from 1 lin. (lower lateral) to 4 lin. long, tips minutely discoid. Spike- 
lets ovoid-elliptic to broad-elliptic in outline, obtuse to subacute, 
§ lin. long, pale green or greyish-green, copiously pubescent with 
spreading hairs, J lin. long. Glumes very thin, similar and subequal 
(or the lower slightly shorter), almost as long as the upper floret,, 
subobtuse, the lower 3-, the upper 5-nerved, the latter more hairy 
with the hairs tubercle-based. Lower floret : valve very similar 
to the upper glume, but glabrous ; valvule slightly shorter, sub- 
obtuse with smooth or obscurely scaberulous keels ; anthers over 
J lin. long. Upper floret ovate-elliptic in outline, subacute, 
almost J lin. long ; valve and valvule thinly papery, whitish, more or 
less glossy and smooth or with a few very minute wartlets. — Jardin,

27. P. viciniflorum, Stapf. Annual (?), up to 3 ft. high, base 
unknown. Culms geniculately ascending, slender, weak, terete, 
simple, the upper part as far as seen 4-noded, nodes exserted. Leaf- 
sheaths terete, moderately tight, quite glabrous and smooth ; ligules 
delicately hyaline, truncate, up to over J lin. long ; blades linear 
from a suddenly and slightly constricted base, tapering to a fine point, .
