Closely allied to D. yilosa, and equally hairy, but a more slender Grass, with longer leaves.— Panicle very
uaraow. Glumee longer than the florets, of which there are only four or five. Lowe,- 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. B. Eig. 1, spikelet; 2, floret; 3,

A very common and variable Grass, growing in dry, rocky places and poor soil; common in Australia and
Tasmama, whence (as from New Zealand) I have examined numerous specimens, under many different-looking
iorma.-Culms and leaves quite glabrous. 8-24 inches high, slender. Mouths o f the sheaths with long, spreading,
silky hairs. PamcU very variable in size, 1-5 inches long, contracted, rarely effuse, sometimes of only four spikelets
Glumes l - i meh long, much longer thau 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 mnch shorter than the glume ; sometimes as long as. at others shorter than, the palea. Middle a ln twisted
below-, as long as or longer than the glumes; never so stout and long as in B . p ilo s a .- ln small starved specimens
the glumes are only four-flowered, and tbe panicle is reduced to a few spikelets.

Culms l i - 3 feet high, strict, stout, leafy throughout, perfectly glabrous everywhere. Sheaths of leaves long,
striate, rather swollen; Vigula 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, \ inch long. Florets six or seven to fourteen, closely imbricated. Glumes
unequal, sharp ; upper three-nerved. quite glabrous, coriaceous ; lower sharp, with obscure nerves. SguarnuU
ovate.—Ml-. 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
Em-opean and American species is found in Tasmania and New Zealand, and in many other parts of the world.—
Culms tufted. Leaves flat or involute, Spikelets pedicelled, clustered into a dense cylindrical spike, small, 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. Eoler, an author on French and German Grasses.)

A handsome Grass, 1-3 feet high, conspicuous for its white, shining, spiked panicle of compressed spikelets,
with inconspicuous awns.—Whole plant more or less downy or glabrous. Leaves flat, a span long, narrow. Panicle
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.

A veiy large geims, found in all parts of tlie -n-orld, but most frequent beyond the Tropics and in cold climates,
where the species often form extensive pastures.—Xearas generally soft and flat, sometimes setaceous. Spikelets twol
or many-flowered. Flowers sometimes unisexual, smooth or webbed with wool at the base. Glumes awnless, nearlv
equal. Lmcer palea bluut, awnless. Stamens one to three. Seed free or adhering to the upper palea.—The'species
of this genus are extremely variable, especially those of Australia and New Zealaud, which ofteu assume widely
diffei-cnt 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 specfes
in their prevalent forms arc distinct and pccidiar in habit. The confusion amongst the Northern species, complexiti
