A very singular genus, consisting of about six Australian and one Javan plant ; all are smaD herbs, growing
iu very shaded, damp woods, and have slender roots, with one or two smaU, pedicelled tubers, very short stems, a
rounded, very membranous leaf, and large, solitary, dingy rufous-coloured, sessile flower, quite unlike that of any
other Orchidcous plant; that of the Tasmanian species resembles a sniai.— Sepals unequal, the upper large and
hooded, the lateral very small and nairow, and, as well as the small petals, hidden under the large upper sepal.
Lip large, tubular or saccate, sometimes spurred ; that of the Tasmanian species is spurless, liooded, with toothed
or fimbriated margins. (Name from wpvs, a helmet, aud avíos, a flower.)

Lindley distinguished this doubtfully as a different species from C. fimbriata, from its having larger flowers
and less fimbriated margins to the labellmn ; but I find both the flowers and leaves to be extremely variable in absolute
and relative size. The flowers are sometimes nearly wliite, and vary from f - f iuch long.—P la t e CVII, B.

There are about six kuown species of this genus, of which four are Austndian, and of the others, one inhabits
New Caledonia, and the other Lord Auckland’s Group, south of New Zealand. L. nigricans, the only Tasmanian
species, is rather common in Australia, extending from Sydney to Swan River, but is very rare in Tasmania ; it
is a stout, herbaceous plant, 4-7 inches high, with dark, red-purple flowers. Root of very stout, often woolly
fibres, springing from the base of the stem, of which one, stouter and longer than the rest, tenninates in an oval,
undivided tuber. Leaves very thick aud fleshy, the lowest largest, ovate or circular, the upper graduaDy passing
into sheathing bracts, which loosely clothe the scapes. Flowei-s three to five, racemose, about 1 inch long, almost
concealed in the large, elliptical, concave bracts. Upper sepals galeate, lanceolate, acute ; lateral sepals about equal
in length, linear, curving downwards. Petals ascending. Lip blunt, with a revolute apex, glandular disc, aud
crisped margins. (Name from Xv7n;pos, mournful, and avíos, a flower ; in allusion to the aspect of the flowers.)

A very singular and rare plant, the only one of its genus hitherto discovered. Lindley, who first described it,
has placed it in Neottieoe, but the relative positions of the anther and stigma on the column appear to me the same
as in Lyperanthus and its allies, with which it further agi-ees in the structure of the lip and its appendages.—A very
small, herbaceous, gi-eenish plant, about 3-4 inches high, with two to three distant, leafy bracts on the stem, and
two to three large, erect flowers, nearly i inch long. Ovary clavate, longer than the acuminate flower-bracts, as
long as the perianth. Sepals nearly equal, oblong-laiiceolate, subacute; dorsal concave; lateral with involute margins.
Petals as long as, hut narrower than, the sepals, with involute margins. Lahellum, short, ascending, broadly
euneate, with a truncate, erose apex, its margins rolled in ; disc with two thickened ridges, terminating in a conical
callus near the base, and in some scattered, small, clavate glands towards the apex ; a few papillæ are also scattered
over the sm-face of the labellum, whose under surface is grauular towards the apex. Column with broad,
membrauous margins. Anther terminal, two-ccUed, acuminate. Stigma a rather prominent, hollow, ovate, depressed
body, below and in front of the veiy base of the anther. (Named in honour of the late G. T. Burnett,
a Professor of Botany in London.)

Perianthium subbilabiatum. Sepala petala subroqualia, linearia. Labellum posticum, unguiculatum,

The species of this genus, of which only tliree are known, are remarkable for the irritability of the lip; this
is posticous, has a long, narrow pedicel, and stands erect, as it were, over the flower, but when the plant is shaken,
or rain comes on, it suddenly shuts down, like a lid, on the flower, and its lamina becomes closely appUed to the
large petaloid column. A Swan River species is said thus to catch iusects, whose struggles appear to disengage the
pollen from the anther, and apply it to the stigma.—Slender, herbaceous plauts, with a solitary, narrow, radical
leaf, and tall scape, bearing one or veiy few, rather large, deep red-brown flowers. The Tasmanian C. major is a
span to 8 inches taU, with a leaf vaiying from narrow-linear to broadly lanceolate, a scape with one smaU, sheathing
bract, and about two flowers, - | - l j inch long. Floxoers pediceUed, with a small bract at the base of the pedicel,
reversed,'the labeUum being above. «Sepafa three, nanw-linear, one hanging down behind the column, and the
two lateral pointing backwards, nearly liorizoutally, notched at the margin. Petals about as long as the column.
Unear, placed against its sides, pointing downw'ards and forwards. Lahellum with a long, slender peduncle, the
lamina produced into a naiTow point at the apex, and at the base into a subulate appendage. Column much larger
