Generally slender Grasses, witb broad or narrow, flat or involute leaves, and very effuse panicles, that have long
thread-like branches, and long pedicels fo the spikelets. The genus differs from Agrostis chiefly in the presence of
a feathery pedicel (of a second flower, which is sometimes though rarely produced) at the back of the upper palea.—
Glumes two, very narrow and sharp, not awned, longer thau the flower. PaUas two : the lower with a dorsal,
often twisted awn, often truncate, and the nerves produced into short awns; upper two-nerved. W free.— The
species of this genus frequent the temperate and colder regions of both hemispheres; the New Zealand and
-iustralian ones are very beautiful, and remarkable for their slender pedicels and spreading branches of the effuse
panicle. (Name in honour of M. Beyeux, an eminent French chemist.)

A very common Tasmanian species,— Cafm tufted, l i foot high. Leaves 6 inches long, i - i inch broad,
flat, smooth or rough to the touch. Panicle very lax, scabrid ; branches very slender, whorled, trichotomous ;
pedicels long, slender. Spikelets larger than in the allied species, i - i inch long, often purple. Glumes narrow!
smooth or scabrid. always so at the keel. Lmcer palea silky at the base, three-fourths as long as the glume, witli
four nerves tbat project at the truncate top, the lateral of which are produced into short awns. Awn inserted at the
middle of the palea, bent, one-half or twice as long as the glumes. Upper palea as long as the lower, with two
short points, longer than the silky pedicel at its back.

Generally a taller plant than D. BiUardieri, with many more, much smaller pale-green spikelets. Oulms 1-3
feet high. Leaves fiat, broad or narrow, quite smooth or scabrous. Panicle 4 -8 inches long, of very numerous,
whorled, slender branches, that do not generally divide so soon as in the former species. Pedicels very slender.
Spikelets i inch long. Glumes smooth, except along the keel, twice as long as the flower, and half as long as the
awn. Lower palea very silky all over, truncate, the ¿^eth produced -into short points, awn inserted at the middle.
Upper palea shorter, blunt or two-toothed. Setula generally very small.—This plant is the Avena fdiformis ol
Forster in Herb. Hook., and also of Labillardiere in Herb. Hook. Mr. Brown however refers Labillardière’s
plant to his D. BiUardieri, with which the figure in Lab. Plant. Nov. Holl. agrees. This appears as common and
variable a plant in Australia, Tasmania, and New Zealand, as Agrostis canina is in Europe ; its synonymy is much
involved.
