A very different species from any of the foregoing, but extremely variable. It is at once recognized by the
pale-yellow horizontal flowers, whose perianth appears compressed from above, and not spreading, and the labellum
has a double downy ridge down the centre ; it is. one of the earliest spring flowers.—Very variable in height, 4-10
inches. Leaves rather numerous, very slender. Mowers generally one or two, but sometimes four, on long peduncles,
i - l è inch long, including the ovary ; upper sepal short, narrow, oblong or broadly ovate, pointing forwards,
and parallel to the lip ; lateral sepals placed close below the lip, liue<ai-, straight or curved, as long or longer than
the Up. Petals pointing forward, narrow or broad, elUptical, about as long as the lip, with short purplish claws.
Lip with two small crenate lateral lobes, like auricles, at tbe base of the larger lobe, which is plane, triangular-
ovate, acute, points forwards, and is very variable iu length.—P la t e CV. A. Fig. 1 , dorsal sepal; 2, petal; 3,

The species of this genus, of which three are described, are aU Australian herbs, but are so closely aUied to
some East Indian and Malayan Island plants {Zosleroshjlis, 111.), that it is doubtful whether all these should not be
brought into the same gexros,.—Mowers rather large, dusky-red or brownish, spiked, solitary or few. Budical leaves
strongly net-veined when dry. Boots fascicled, of thick, jointed or annulate fibres.—Tlie C. longifolia is a tall
herb, 10-24 inches high, with one rather coriaceous, flat, radical, linear-lanceolate leaf on a long petiole. Scape
erect, rather stout, with a few distant, short, sheathing bracts. Mowers tliree to eight, rather distant, sessile, upwards
of an inch broad. Ovary curved, slender, f inch long, about twice as long as the bracts. Sepals naiiow-linear,
dirty yellow-green, almost au inch long. Petals shorter, smaller, move subulate, of the same colour. Lip superior
(i. e. posticous), pointing forward, its face looking downward, broadly-obovate, oblong, blunt, margins recurved, with
three medial ridges terminating in a double tubercle towards the apex, dirty reddish-brown. Column very short,
hidden in the cuculhate base of the lip. its margins expanded, membranous, and torn. (Name from k/dvtttos, concealed,

A large genus of very variable plauts, confined, so far as is at present known, to Australia and the New Zealand
Islands. The species may readily be recognized by their coated bulbs, which are not pedicelled, solitary fistu-
har leaves, and spike of smaU flowers, which have the labeUum above. Mr. Archer has made a detailed study of the
Tasmaniau species, aud I have gladly avaUed myself of his arrangement and characters of the species; these
appear to me good, though I must oivn it is not possible to find in all the dried specimens of any species all the
characters we agi-ee iu considering to be the diagnostics of that species i stUl the difficulties are not nearly so great in
this genus as in Microtis and Thelymitra. The genus Genoplesium, founded by Brown upon a drawing of Bauer’s,
we have included iu Prasophyllum, with an amended character, Bauer appearing to us to have confounded the
petals with the stamiuodia, though we must confess that it is difficult to understand how he c<ame to do so ; as
however the different views of these organs, as represented by Bauer, are not consistent with one another, we are
unavoidably compeUed to suspect some error.—(Name from npaoov, a leek, and <f>vXXov, a leaf.)
