246 FLORA OF NEW ZEALAND. [ Orchidee. 
suberecta v. reflexa. Labellum breve unguiculatum, planum, deflexum, basi 9-callosum. Columna semi- 
teres, superne alata. Anthera terminalis. Pollinia 4.—Herbe terrestres, sylvicola, tenella, tuberose, 
lfohata, pauciflore ; perianthio explanato. 
A very small genus of delicate green herbaceous Australian, Tasmanian, and New Zealand plants, with tuberous 
roots, slender stems, solitary, 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. Zip deflexed, with an oblong membranous lamina, a short claw, and two lumps at 
the base. ı Column curved, winged above. Anther terminal. (Name from xupros, curved, and orvhos, a style.) 
1. Cyrtostylis oblonga, Hook. fil. ; folio ovato-oblongo obtuso apiculato basi cordato sessili rarius in 
petiolum brevem angustato, labello obovato-oblongo apice rotundato v. retuso apiculato. 
Has. Northern Island. Frequent in moist woods and on shady banks, Sinclair, Colenso, ete. 
Leaf from near the root, 1—1 inch long, oblong-ovate, blunt, apiculate, generally deeply cordate at the base, rarely 
narrowed into a blunt petiole. Flowers usually one or two, $ inch long from tip of upper sepal to that of lip, 
yellow-green, with a membranous red-brown tip. Sepals and petals very narrow. Lip oblong, tip often rather 
dilated, retuse and apiculate. 
2. Cyrtostylis rotundifolia, Hook. fil.; folio orbiculari obtuso profunde cordato, labello lineari- 
oblongo obtuso v. subacuto. 
Has. Northern Island. Raukawa Ridge, Hawkes’s Bay, and Cape Kidnapper, Colenso. 
Very similar to C. oblonga, but smaller, shorter, with an orbicular leaf, blunt and cordate at the base, and nar- 
rower lip, rather narrower at the base than above; the latter organ is however a variable one in C. oblonga. 
3. Cyrtostylis macrophylla, Hook. fil. ; folio amplo orbiculari obtuso v. apiculato, floribus majusculis, 
labello lineari-oblongo obtuso. 
Has. Northern Island. East coast, Colenso. 
A much larger species than either of the former. Leaf 1-13 inch broad. Siem 2-5 inches high. Flowers 
1—$ inch long, from the upper sepal to end of labellum ; the latter is narrow, linear-oblong. 
Gen. XII. ADENOCHILUS, Hook. fil. 
Perianthium subbilabiatum, puberulum ; sepalum supremum subgaleatum, acuminatum, basi dorso 
columnee adnatum ; lateralia labello supposita, lanceolata, acuminata, obliqua, trinervia; petala suberecta, 
lineari-lanceolata. Labellum breve unguiculatum ; lamina subguadrata, triloba, lobo intermedio caudato 
discoque glandulis stipitatis sub-4-seriatis ornato. Columna elongata, alata; alis ultra antheram productis, 
apice subdentatis. Anthera terminalis, 2-locularis—Herba gracillima, glaberrima, habitu Eriochili; caule 
medio unifoliato ; folio sessili, ovato, acuto; pedunculo gracili, 1-floro, medio 1-bracteato ; ovario erecto, 
valde elongato, basi bractea vaginante incluso’; flore flavido. 
1. Adenochilus gracilis, Hook. fil. (Tas. LVI. 4.) 
Has. Northern Island. Bay of Plenty, Colenso. 
A very curious plant, intermediate between Chiloglottis, Caladenia, and Hriochilus ; 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 ‚Briochilus in the glandular labellum and sessile lateral sepals, agreeing however with 
that genus remarkably in habit, and in the very long ovary. Stems slender, a span high, with one ovate, oblong, 
acute, membranous, sessile leaf, placed half-way up, $ inch long. Flower solitary, glandular, erect. Ovary slender, 
3 inch long, surrounded with a sheathing bract at the base. Perianth 3 inch long; leaflets all acuminate, glandular. 
Upper sepal hooded, adnate to the base of the column as in Péerostylis ; lateral longer, placed under the labellum,
