Deschampsia. | GRAMINES. 877 
broad, pale, membranous, grooved; ligules long, scarious, acute, 
broader than the blade at the base. Panicle slender, erect, 1-3 in. 
long, usually lax but sometimes contracted ; branches few, capil- 
lary, smooth or minutely scaberulous, sparingly divided. Spikelets 
few, small, ;4—41in. long, pale-green, shining, 2-flowered. Two 
outer glumes unequal, the lower about $ the length of the spikelet, 
oblong-lanceolate, acute, l-nerved, the upper about 2 the length of 
the spikelet, broader and more obtuse, 3-nerved; 3rd and 4th or 
flowering glumes broadly oblong, hyaline, membranous, faintly 
3-5-nerved, quite glabrous at the base, broadly truncate at the 
apex and irregularly minutely denticulate, awn wanting. Palea 
bifid, 2-nerved, nerves faintly ciliate. Rhachilla elongated between 
the flowering glumes and produced beyond the upper flower into a 
slender bristle, quite glabrous.—D. Hookeri, Kirk in Journ. Bot. 
xxiv. (1891) 237 (in part).

Although yery closely allied to D. Chapmani and D. tenella this appears to 
be sufficiently distinct from both in the irregularly denticulate apex of the 
flowering glume and the total absence of the dorsal awn. Mr. Kirk united ali 
three under the name of D. Hookevi.

Culms tufted, branched at the base, quite smooth, leafy, 6-18 in. 
high. Leaves longer or shorter than the culms, very narrow, flat or 
involute, often almost filiforin, flaccid ; sheaths long, narrow, deeply 
grooved ; ligules elongated, acute, broader than the blade at the base. 
Panicle very slender, 3-6in. long or more, effuse or contracted, laxly 
and sparingly branched ; branches capillary, minutely scaberulous, 
usually trichotomously divided. Spikelets few, small, about din. 
long, pale-green, glistening, 2-flowered. Two outer glumes unequal, 
uuch shorter than the spikelet, oblong-lanceolate, membranous, 
the lower short, 1-nerved, the upper 4 longer, equalling the lower 
flower or slightly exceeding it, 3-nerved; 3rd and 4th or flowering 
glumes broadly oblong, membranous, faintly 3—-5-nerved, glabrous at 
the base or rarely with few very short hairs, truncate at the apex and 
more or less irregularly 3—5-toothed; awn usually present on both 
glumes, from the back a little distance below the tip. Palea bifid, 
2-nerved, nerves ciliate. Rhachilla elongated between the flowering 
glumes and produced beyond the upper flower into a slender bristle, 
quite glabrous.—D. Hookeri, Kirk in Journ. Bot. xxiv. (1891) 237
