H ab . Middle Island : Aglionby Plains and Motucka Talley, neai' Nelson, Monro.
Closely allied to D. pilosa, and equally hairy, but a more slender Grass, with longer leaves.—Paiiirfe very
nan-ow. 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.—P l a t e LXIX. B. Fig. 1 , spikelet; 3 , floret; 3

places, Colenso; Gordon’s Nob, near Nelson, Monro.
A very conunou and variable Grass, growing in dry. rocky places aud poor sob; common in Australia and
Tasmama, whence (as from New Zealand) I have examined numerous specimens, under many different-looking
forms.-OGM» and Uaves quite glabrous. 8-24 inches high, slender. MoutU of the sheaths with long, spreading,
sffky hairs. PanwU very vanable in size. 1-3 mches long, contracted, rarely effuse, sometimes of only four spikelets,
Bbmes mch long, much longer than the four to six florets. Lower palea very viUous at the base and above the
midGe; hairs of the upper series sometimes as long as the lateral awns; the hatter 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. p ilo sa .-U small starved specimens
the glumes are only four-flowered, aud the panicle is reduced to a few spikelets.

A small genus of aquatic Grasses, whose seeds have been used as bread-corn in time of famine, and called
Manna . - - f e r a flat Culms creeping below. PanicU long, simple and racemose, or more branehed, with
whorled branches Glumes concave, blunt, many-flowered. Plowers numerous, imbricated on a flexuous rachis, all
hermaphrodite. L ^ e r paUa elliptical, ovate, blunt, or with three blunt teeth and seven nerves ; upper rather shorter
t a » two or three f e i free.-The species are few in number; one of these. G. fluitans, though very widely
Gstributed, has not hitherto been found in New Zealand. (Name from yAu^pos, »»»»»(. in allusion to the eatabie
grams.)

Culms l i -2 feet high, strict, stout, leafy throughout, perfectly glabrous everywhere. SheatU of leaves long,
striate, rather swollen j lìgula short, broad, membranous. Lamina short, 2-4 inches, subulate, strict, erect, involute.
Panicle 4-6 inches long, very slender, strict, with short, stout, erect, appressed branches. Spikelets terete, rather
crowded, pale-yellow, almost shining, a inch long. Florets six or seven to foiu-teen, closely imbricated. Glumes
unequal, sharp ; upper tbree-nerved. Faleæ quite glabrous, coriaceous ; lower sharp, with obscure nerves. Squamule
ovate.—Mr. Gunn has also sent me specimens of this plant from Tasmania ; they are much larger than the New
Zealand ones, but not otherwise different.

A small genus of Grasses, scattered over the temperate regions of the Northern hemisphere, of which one
European and American species is found in Tasmania and New Zealand, and in many other parts of the world.__
Culms tufted. Leaves fiat or involute. Spikelets pediceUed, clustered into a dense cylindrical spike, smaU, two- or
many-flowered. Glumes keeled, unequal, awnless. Lower palea sharp, awnless, or awned at the tip or back; upper
bifid at the point. Seed free. (Name in honour of G. L. Koler, an author on French and German Grasses.)

H a b . Middle Island : Aglionby Plains, near Nelson, Monro. (Native of England.)
A handsome Grass, 1-3 feet high, conspicuous for its white, shining, spiked pamcle of compressed spikelets,
with inconspicuous awns.—Whole plant more or less downy or glabrous. Leaves flat, a span long, narrow. PanicU
spiked, erect, 3-5 inches long, interrupted at the lower parts. Spikelets very variable iu size, imbricate, erect, two-
to five-flowered. Glumes shorter than the florets, unequal, acute. Lower palea with a short awn at the back below
the point.—This is also a Tasmanian Grass, and is very common in Britain.

Spicnlæ 2-8-floræ ; floribus distichis, hermaphroditis, nunc basi lanatis, interdum abortu dioicis.

sessilibus et spicatis.

where the species often form extensive pastures.—fe re» generally soft and flat, sometimes setaceous. SpiheteU two!
01- many-flowered. Flowers sometimes unisexual, smooth or wehhed with wool at the base. Glumes awnless. nearly
equal. Lower patea blunt. awGess. Stamens one to three. Seed free or adhering to the upper palea.—The’species
of this genus arc extremely variable, espeoiolly those of Australia and New ZeGand, which often assume widely
diflcrcnt forms. I have not united any of the New Zealand species with South American or European ones, though
some are so very closely allied to these, that I can hardly discriminate between them ; still the New Zealand species
in thcii- prevalent forms arc distinct and pecidiar in habit. The confusion amongst the Northern species, com^Iexity
