304 FLORA OF NEW ZEALAND. [ Graminee. 
medioque villosa, fasciculis superioribus pilorum elongatis paleam occultantibus, aristis lateralibus pales 
sequilongis gluma brevioribus, intermedia gracili breviter exserta. (Tas. LXIX. B.) 
Has. Middle Island: Aglionby Plains and Motucka Valley, near Nelson, Monro. 
Closely allied to D. pilosa, and equally hairy, but a more slender Grass, with longer leaves.— Panicle very 
narrow.  Glumes longer than the florets, of which there are only four or five. Lower palea with a dense tuft of long 
hairs above the middle, and three awns, of which the middle is as long as the palea, and half as long as the slender 
intermediate awn, which is scarcely longer than the glumes.—PLATE LXIX. 2. Fig. 1, spikelet; 2, floret; 8, 
scale; 4, stamen ; 5, ovary :—all magnified.

longioribus, palea inferiore basi medioque barbata, fasciculis superioribus pilorum aristis lateralibus (palece 
zquilongis brevioribusve) sequilongis v. 4 brevioribus, arista intermedia torta glumis sequilonga v. paulo 
longiore.— Br. Prodr. A. Cunn. Herb. N. Zeald. Lab. Fl. Nov. Holl. v. 1. p. 26. €. 33. Trin. Sp.

Has. Northern and Middle Islands: vars. a and 8, abundant, Cunningham, etc.; var. y, in moun- 
tainous places, Colenso ; Gordon's Nob, near Nelson, Monro. 
A very common and variable Grass, growing in dry, rocky places and poor soil; common in Australia and 
Tasmania, whence (as from New Zealand) I have examined numerous specimens, under many different-looking 
forms.—Culms and leaves quite glabrous, 8-24 inches high, slender. Mouths of the sheaths with long, spreading, 
silky hairs. Panicle very variable in size, 1-5 inches long, contracted, rarely effuse, sometimes of only four spikelets. 
Glumes 1—1 inch long, much longer than the four to six florets. Lower palea very villous at the base and above the 
middle; hairs of the upper series sometimes as long as the lateral awns; the latter vary much in length, being 
always much shorter than the glume; sometimes as long as, at others shorter than, the palea. Middle awn twisted 
below, as long as or longer than the glumes; never so stout and long as in D. pilosa.—In small starved specimens 
the glumes are only four-flowered, and the panicle is reduced to a few spikelets. 
Gen. XXI. GLYCERIA, Br. 
Spicula multiflore; floribus distichis imbricatis hermaphroditis. Glume 2, concave, obtuse; infe- 
rior brevior. Palee 2, subsequilonge ; inferior ovato-elliptica, obtusa v. obtuse 3-loba, 7-nervis. Squamule 
2, plus minusve inter se connate. Stamina 2-3. Curyopsis oblonga, libera.—Gramina aquatica, repentia ; 
foliis plants ; panicule simplices v. ramosa ; ramis fasciculatis, subverticillatis. 
A small genus of aquatic Grasses, whose seeds have been used as bread-corn in time of famine, and called 
Manna.—L£eaves flat. Culms creeping below. Panicle long, simple and racemose, or more branched, with 
whorled branches. Glumes concave, blunt, many-flowered. Flowers numerous, imbricated on a flexuous rachis, all 
hermaphrodite. Lower palea elliptical, ovate, blunt, or with three blunt teeth and seven nerves ; upper rather shorter. 
Stamens two or three. Seed free.— The species are few in number; one of these, G. fluitans, though very widely 
distributed, has not hitherto been found in New Zealand. (Name from yAvxepos, sweet, in allusion to the eatable 
grains.)
