A small Australian genus, of about six species, the majority of them natives of Swan River. E. autumnalis is
a slender, glandular, pubescent plant, 4-10 inches high, with a round, tuberous root, a small, ovate, sessile leaf,
produced at a different season from the flower, and one or two terminal, pale rose-coloured flowers, inch long.
—Bract short, blunt. Ovary slender. Perianth two-lipped ; the upper lip of a linear, erect dorsal sepal, and two
similar petals; the lower of two petioled, elliptic-lanceolate, acuminate, prominent sepals. Lahellum short, recurved,
pubescent, entii-e, without glands or appendages. Column straight, its margins hardly dilated. (Name

A large extratropical Australian genus, of which about 40 species are known, and there arc several others
natives of New Zealand.—Glandular, sometimes villous, pubescent herbs, ivith few root-fibres terminating iu globose
tubers, and one sessile, sheathing, radical leaf. Flowex-s glandular, solitaiy or few, of all colours, large or small, sometimes
with very long, slender sepals and petals, and commonly called Buttcrfly-plants in Tasmania. Dorsal sepal
generally concave, pointing forwards; lateral placed beneath the labellum. Petals erect or spreading. Labellum
clawed, cucullate, with incuiTcd, membranous, often fimbriate margins, entire or three-lobed, generally much contracted
beyond tlie middle, its disc with two or more rows of pedicelled glands. Coluxnn with membranous margins.
(Name from «aXos, beautiful, and aSijv, a gland; in allusion to the glandular labellum.)

Archer’s specimens of this fine species are the only Tasmanian ones I have seen; they are about a span long,
aud covered with long, patent, soft hams. Flowers of a dark reddish-brown colour, 1^-2 inches broad; the sepals
and petals long-linear, but not thickened at the apex. Lip with a rather long, slender, revolute apex, slightly crenulate,

A very elegant species, more villous than C. filamentosa, and with paler flowers, easily recognized by the sepals
being lineav-oblong for half their length, and then filiform, much louger than the petals, and being often somewhat
dilated towards the tips; further also by the labellum being vciy broad at the middle, its margins there pectinate,
and suddenly contracting to a narrow, creniflatc, reeui-ved apex; also by the four 'ows of long, purple glands on
the deep-puiqfle lip, and by the winged, hut not auriculate, upper one-third of tl.e colmnn.—P la t e CXXII. B.
