Gen. X. CHILOGLOTTIS, Br. 
Perianthium bilabiatum ; sepalo dorsali fornicato, lateralibus labello suppositis. Petala ascendentia v. 
reflexa. Zabellum unguiculatum, basi appendiculata ; appendice lingulata v. columnari; disco glanduloso. 
Columna elongata, apice bifida. Anthera terminalis. Pollinia 4.—Herbe terrestres, caudiculis radicalibus 
basi tuberiferis ; foliis 2, radicalibus; scapo infra florem unibracteato, 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 in the same island and Australia, and a 
third hitherto observed only in the Auckland and Campbell Islands, south of New Zealand.—Root a simple, elon- 
gated, descending caudicle, 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 sheathing bract near the middle. Flower 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 dise. (Name from xeuvos, a 
lip, and yAwrra, the tongue; from the form of the appendix of the first-described species.) 
l. Chiloglottis diphylla (Br. Prodr. 322) ; foliis petiolatis ovato-lanceolatis, scapo gracili, sepalo 
dorsali lineari apicem versus dilatato, lateralibus basi connatis, petalis deflexis, appendice labelli spathulata 
lingulata, disco glandulis stipitatis confertis, columna basi appendice transversa.—Lind/. Gen. et Sp. Orch.

DistriB. New South Wales. 
A slender species, 3-6 inches high, with two petiolate, ovate, lanceolate leaves. Flowers about 2 inch across. 
Sepals narrow, linear; lateral united at the base, terete at the apex, deflexed or even recurved. Petals linear, de- 
flexed. — Labellum spathulate, dark red-brown, with a large black-purple ligulate gland at the base, backed with 
smaller capitate ones, and a crowd of pedicelled glands 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. Chiloglottis Gunnii (Lindl. Gen. et Sp. Orchid. 387); robusta, foliis ovatis breve petiolatis, 
scapo brevi, sepalo dorsali unguiculato spathulato acuminato, lateralibus ovato-subulatis ascendentibus, 
petalis erectis, labello trulliformi, glandulis sparsis, appendice columnari. (Gunn, 913.) (Tas. CVIII. B.) 
Has. Shaded banks, ete.: Circular Head, Cheshunt, and Hobarton, Gunn, Archer, etc.— (Fl. Oct.) 
A small, robust species, 2-4 inches high. Leaves sessile, or shortly petioled. Flowering scape generally thick. 
Flower an inch across, with very much broader sepals and petals than C. diphylla, the upper sepal unguiculate and 
spathulate, 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.—PrArg CVIII. B. Fig. 1, labellum ;
