A very small genus of delicate green herbaceous Australian, Tasmanian, and New Zealand plants, with tuberous
roots, slender stems, solitaiy, broad, cordate leaves, and few-flowered racemes of expanded somewhat two-lipped
greenish flowers. Upper sepal and petals narrow, erect, or ascending, the latter sometimes reflexed ; two lower
sepals also narrow, deflexed. Lip deflexed, with au oblong membranous lamina, a short claw, and two lumps at
the base. Column curved, winged above. Anther terminal. (Name from Kvpros, curved, and o-t-uXoç, a style.)

petiolum brevem angustato, labello obovato-oblongo apice rotundato v. retuso apiculato.
H a b . Northern Island. Frequent in moist woods and ou shady banks, Sinclair, Colenso, etc.
Leaf from near the root, 4- I inch long, oblong-ovate, blunt, apiculate, generally deeply cordate at the base, rarely
narrowed into a blunt petiole. Flowers usually one or two, g inch long from tip of upper sepal to that of lip,
yeUow-green, with a membranous red-brown tip. Sepals and petals very narrow. Lip oblong, tip often rather
dilated, retuse and apiculate.

oblougo obtuso V. subacuto.
H a b . Northern Island. Raukawa Ridge, Hawkes’s Bay, and Cape Kidnapper, Colenso.
Very similar to C. ohlonga, but smaller, shorter, with an orbicular leaf, blunt and cordate at the base, and narrower
lip, rather narrower at the base than above ; tbe latter organ is however a variable one in C. ohlonga.

1. Adenochilus gracilis, Hook. fil. (Ta b . LYI. A.)
H a b . Northern Island. Bay of Plenty, Colenso.
A veiy curious plant, intermediate between Chiloglotiis, Caladenia, and Friochilus; differing from the former in
the solitary leaf, glandular perianth, and want of the appendix at the base of the lip ; from Caladenia in habit and
two-lobed column ; and from FiriocMlus in the glandular labellum and sessile lateral sepals, agreeing however with
that genus remarkably in habit, and in tbe very long ovary. Stems slender, a span high, with one ovate, oblong,
acute, membranous, sessile leaf, placed half-way up, f inch long. Floicer solitary, glandular, erect. Ovai'y slender,
f inch long, surroimded with a sheathing bract at the base. Ferianth g inch long ; leaflets all acuminate, glandular.
Upper sepal hooded, adnate to the base of the column as in Pterostylis ; lateral longer, placed under the labellum
free, obliquely three-nerved. Petals lanceolate, spreading. Lip oblong-quadrate, with a short claw and a long recurved
tail ; several rows of stipitate glands run down the lamina, and are continued on to the tail. Column curved,
winged, bifid at the top, lobes toothed. Anther-case adnate, hidden behind the broad stigma on the face of the
column below the apex, very broad, two-celled. (Name from cÔtju, a gland, aud x<Aof, a lip.)—P la te LVI. A.

Terrestrial tuberous-rooted herbs, more or less glandular. Leaves one or two. Flowers solitary or several.
Upper sepal plane or hooded ; two lateral free or joined at the base ; petals narrow. Lip with a claw, rarely sessile,
entire or three-lobed, sometimes nan-owed; disc with two or more rows of stipitate glands. Column curved,

H a b . Middle Island. Oia^o, Lyall.
A very much larger-flowered and stouter species than C. minor, with one to two flowers, each twice as large
as in that species, and broad sepals, which are liuear-oblong, or obovate and acuminate. (This is probably the Caladenia
No. 4 of ‘Flora Antarctica,’ p. 70.)
3. Caladenia? bifolia, Hook, fil.; glanduloso-pubescens, foliis 2 basi caulis suboppositis ovato-
oblongis subacutis, scapo nudo, flore solitario basi bracteato, sepahs petalisque linearibus, labello vix
unguiculato late obovato basi glanduhs 2-seriatis ornato, columna breviter alata, anthera ad apicem co-
lumuæ sessili.
H a b . Middle Island. Otago, Lyall.
This is apparently the Orchideous plant No. 5 Caladenia ? of Lord Auckland’s Group mentioned in the ‘ Flora
Antarctica,’ p. 70, and differs from Caladenia in the almost sessile labellum.—Whole plant glandular, 4 inches high,
robust. Root of small tubers and thiçk large fibres. Leaves nearly opposite, sessile, 1 inch long, ovate-oblong.
Scape with one bract below the flower. Ovary obovate, 4 iuch long. Flower rather large, f inch across. Sepah
and petaU linear, blunt. Lip obovate, with two short rows of linear glands near the base. Column with narrow
wings and the anther at the top.—This differs from Caladenia in having two leaves, but the upper of them is represented
in the other species of the genus by the bract on the middle of the scape.
