A very distinct species, of the same habit aud general appearance as F. brachystachyum, but more slender,

Very variable in size, 3-10 inches high, always slender, with a leafless, one-bracteatc scape, and rather long
spikes of eleven to thirty ascending, minute flowers, smaller than in any of the preceding of this section. It is

Gen. II I. CALOCHILUS, Br.
I ringens. Sepala patentia, libera, ®qualia; lateralia labello supposita. Petala minora,
erecta. Labellum anticum, sessile, simplex, liberum, acuminatum, disco marginibusque barbatum. Columna

The few known plants of this genus are very beautiful, and all Australian ; they are easily recognized by
the red-hrown (rarely yellowish or wliite) flowers, with an ovate-lanceolate lahellum, covered with a copious, pendulous
beard of deUcate filaments.—fZooi an undivided bulb, above which are very thick, spreading, cylindrical rootlets
; stem 12-18 inches high, with one or a very few narrow radical leaves, and some sheathing ones on the scape.
Flowers few, large, racemose or spicate, with tliree nearly equal, lanceolate sepals, of which two are placed under
the labellum, two inner petals similai- to the sepals, and a long, pendulous, crinite lip. Column short, hooded,
enclosing un erect, acute anther.—The C. campestris has a four- to eight-flowered spike; the flowers about half au
inch across; labellum longer than the sepals, terminating in a ligulate point of very variable length. I find such
gi-eat differences in the length of the labeUum and its Ugulate apex, iu the relative length of the bracts and ovaries,
and in the size and colour of the flowers of the different forms of Calochilus, that I much doubt there being more
than one species of the genus. (Name from koAos, beautiful, and ^ Iw)

A large and widely-diffused genus, the only Tasmanian, or indeed Australian, species of which is found in
many parts of the globe, a very rare instance of wide distribution in the Order. The New Zealand species, which
I distinguished in the Flora of that country as S. Nova-Zelandia, appears, according to Ur. Lindley, to be a variety
of the Australian, differing in the narrower labeUum, but not constantly.—The S. Australis is a small, herbaceous
plant, 4 inches to a span high, with a root of thick, unbrauched fibres, several linear, radical leaves, and a vaginate
scape, terminated by a twisted spike of small, reddish, crowded flowers. Scape and spike glandular. Bracts broadly
ovate-acuminate, as long as the ovary. Flowers \ inch long, horizontal. Sepals and petals ovate-lanceolate, subacute
; dorsal sepal and petals forming together a galea; lateral sepals rather saccate at the base. Lip hardly
longer than the sepals, white, shortly clawed, linear-oblong or obovate-oblong, with crumpled and crenate margins.
Column short. Anther dorsal. (Name from crneipa, a spire, and avíos, afiower.)
