D i s t r ib . Swan River {Drummond).
A veiy ciu-ious little species, of which I have seen no leaves, but Archer says these appear in winter.—
rather stout, strict, 3 - 6 inches high, hearing two or three remote, small, slieathing bracts. Floicers one or two in
my Tasmanian spcchnens, four in a Swan River one, erect, about ^ inch long, including the ovary, puberubus
or glabrous, erect. Galea with a short incurved apex. Dorsal sepal acuminate, rather shorter than the blunt petals.
Petals much contracted and obliquely euneate at the base, shortly sickle-shaped, white, with red-hrown nerves and
margins. Lower lip closely applied to the galea, shorter than it is, with two short, ineuiwcd, uncinate teeth separated
by a wide sinus. Lahellum small, included, Hnear-oblong. with a three-forked apex. Column wings with a
descending auricle, and ascending, subulate, uncinate arm.—P la t e CXVI. C. Fig. 1. flower ; 2, petal ; 3 , labellum ;

I have referred this plant to Brown’s P. parvifiora, with the insufficient description of which it quite agrees ;
few-ftowered specimens of P . aphylla may however equally be included in that description. The present plant is
taller, more slender than P. aphylla, has a scape 3-10 inches high, three- to eight-flowered (rarely move), and bears
small, ovate, petiolate leaves, which are home on my specimens on lateral shoots at the base of the flowemg
scapes. It further differs from P. aphylla in the much longer and deflexed apex of the galea, and in the longer
acuminate petals.
§ 5. Leaves all cauline, alternate. Scape one- to four-flowered. Lower lip of perianth defiexed.
15. P te ro styU s long ifo lia (Bp. Proar. 327) ; scapo 1-6-floro gracili, foiiis aiternis angusto ianoeo-

H a b . Common in dry soil in forest land.— (FI. Oct.) (a. v )
D is t r ib . New South Wales and Victoria.
I have followed Lindley in referring this common plant to Brown’s P. longifolia.— Stem very slender, wiry,
4-14 inches tall, leafy throughout its length, with narrow-lanceolate or subulate-acuminate leaves. Flowers 3-5
(sometimes 6- 8, but rarely), pale-green, about i inch long, puberulous or glabrous. Galea horizontal, broad, suddenly
acuminate; dorsal sepal rather longer than the petals. Lower Up suddenly bent down, bifid; lobes ovate,
acuminate. Lahellum very small, short, ciliated, with a short, blunt appendix. Wings of column cUiated, siiortly
auriculate.—P la t e CXVII. JS. Fig. 1, front, and 2 , side view of labellum; 3, front, and 4, side view of column ;

Perianthium bilabiatum; sepalo dorsali fornicato, lateralibus labello suppositis. Petala ascendentia v.
reflexa. Labellum unguiculatum, basi appendiculata ; appendice lingulata v. columnari ; disco glanduloso.
Columna elongata, apice bifida. Anthera terminalis. Pollinia 4.—Herbm terrestres, caudiculis radicalibus
basi tuberiferis-, foliis 2, radicalibus; scapo infra fo rem unibracleato, unifloro; floribus luridis, suberectis ;
pedicello post anthesin elongato.
A very peculiar-looking genus, closely allied to Cyrtostylis, but of a much more robust habit, and two-leaved.
Only three species are known, one confined to Tasmania, a second found iu the same island and Australia, and a
third hitherto observed only in the Auckland and Campbell Islands, south of New Zealand.—Pooi a simple, elongated,
descending candide, terminating in a round naked tuber, and giving off from near the base of the stem other
caudicles, whose tubers bear stems in the following year. Leaves two, at the base of the stem, with a sheath round
their base. Scape rather stout, erect, with one slieathing bract near the middle. Fhwer rather large, erect; dorsal
sepal arched, acute; lateral placed under the labellum, curved downwards. Petals narrow, ascending or deflexed.
Labellum clawed, rather fleshy, simple, ovate, with large, erect, capitate glands on the disc. (Name from xiiXos, a
lip, and yXcuTxa, the tongue-, from the form of the appendix of the first-described species.)

Distrib. New South Wales.
A slender species, 3-6 inches high, with two petiolate, ovate, lanceolate leaves. Flowers about inch across.
Sepals narrow, linear ; lateral united at the base, terete .at the apex, deflexed or even recurved. Petals linear, deflexed.
Labellum spathulatc, dark red-brown, with a large black-purple ligulate gland at the base, backed with
smaller capitate ones, and a cro'vd of pedicelled glaads on the disc.—The form and size of the appendix and glands
are variable, and sometimes they resemble an ant sitting on the disc of the labellum : (see Ross’s Hobarton Almanac,
1833.)
2. C h ilo g lo ttis Gunnii (Lindl. Gen. et Sp. Orchid. 387) ; robusta, foliis ovatis breve petiolatis,
scapo brevi, septilo dorsali unguiculato spathulato aeuminato, lateralibus ovato-subulatis ascendentibus,
petalis erectis, labello truUiformi, glandulis sparsis, appendice columnari. {Gunn, 913.) (Tab. C \ II I . BL)
Hab. Shaded banks, etc. : Circular Head, Cheshunt, and Hobarton, Gunn, Archer, etc.— (FÌ. Oct.)
A small, robust species, 2—1 inches high. Leaves sessile, or shortly petioled. Flowering scape generally thick.
Flower au inch across, with very much broader sepals and petals than C. diphylla, the upper sepal unguiculate and
spathulatc, the lateral not united at the base, ascending and recurved. Petals ascending. Labellum of the form of
a trowel, with numerous stipitate glands, which often are so arranged as to resemble an ant, as in C. diphylla.—In
both species the pedicel of the flower elongates remarkably after flowering.—P la t e CVIII. B. Fig. 1, labellum ;
