1. P. conjugatum, Berg, in Act. Helv. vii. 129, t. 8. Perennial, up 
to over 2 ft. high, growing in small tufts with often very long rooting 
runners, throwing up secondary culms from the nodes. Culms erect 
or geniculately ascending, 5-7-noded, glabrous, internodes more or 
less exserted, the internodes of the runners usually much compressed 
and often arching. Leaf-sheaths compressed and keeled, particu- 
larly the lower which are more or less flabellately arranged, loose or 
(the upper) tight, striate, smooth and glabrous except on the upwards 
ciliate margins and a transverse line of short hairs at the junction 
with the blade and in the runners, the frequently long and softly 
bearded nodes ; ligules short, membranous, truncate, often with a 
line of hairs behind them ; blades linear-lanceolate to linear, slightly 
narrowed or rounded at the base, long- tapering to an acute point, 
up to 7 in. by 3-6 lin., green, soft to almost flaccid, rigidly ciliate and 
scaberulous along the margins, otherwise glabrous and more or less 
(rarely very) hairy, midrib fine, whitish, primary lateral nerves 
about 5 on each side, faint. Spike-like racemes paired (rarely 3-nate) , 
sessile or subsessile or one of them shortly peduncled, divergent, 
2-6 in. long ; rhachis herbaceous, subtriquetrous, about J-| lin. 
wide, grooved on the back with smooth cartilaginous lateral angles 
and a much projecting or sublamelliform facial angle, glabrous except 
at the pubescent base, internodes J lin. long ; pedicels solitary, with 
thickened tips, curved, J lin. long. Spikelets 2-seriate, not or 
slightly imbricate, but usually closely packed, broad-elliptic, sub- 
obtuse or apiculate to shortly acute, plano-convex, |-| lin. long, 
greenish-yellow, at length brownish. Lower glume 0 ; upper corre- 
sponding in size and outline to the spikelet, convex, thinly mem- 
branous with a stout green marginal nerve on each side, ciliate, the 
cilia fine, up to over 1 lin. long, white. Lower floret : valve ve^ 
similar to the upper glume and equalling it, but flat and glabrous 
with more delicate marginal nerves ; valvule 0. Upper floret ^ : 
valve like that of the lower, if not more distinctly apiculate or acute 
and 3-nerved, thinly crustaceous, straw-coloured ; valvule with 
narrow flaps. Anthers yellow and orange, J lin. long. Stigmas 
orange. Grain elliptic-rotundate, rather flat, J-f lin. long ; 
scutellum of similar shape, equalling almost one- third of the grain. —
