Orchidea. | FLORA OF NEW ZEALAND. 243 
which has no staminodia, and a broad two-lobed blunt anther, placed behind the stigma.—This species differs from 
the S. australis of Port Jackson in the narrow labellum. (Name from corren, a spike, and avOos, a flower.)

Gen. VII. ORTHOCERAS, Br. 
Sepala lateralia, anguste linearia, erecta; superiore crasso galeato obtuso; petala parva, linearia, bifida 
v. integra, sub galea conniventia. Labellum sessile, 3-lobum, breve unguiculatum. Columna brevis; 
staminodiis petaloideis. Antkera dorsalis mutica v. acuta.—Herbe terrestres, iubere indiviso; foliis 
Jliformidus. 
A very small genus, consisting of one New Holland and one New Zealand species. Root a long ovoid tuber. 
Stem rather stout, erect, 1-2 feet high. Radical leaves sheathing at the base, filiform. Stem sheathed. ` Spike 
flexuous, four- to eight-flowered. Bracts ovate or lanceolate, acuminate, longer than the flowers. Ovaries pedicellate, 
large, linear-oblong, erect, 1-3 inch long. Perianth shorter than the ovary. Lateral sepals linear, quite erect; 
upper concave, hooded, fleshy, blunt. Petals small, linear-oblong, bifid. Zip short, three-lobed, with two glands 
at the base. Staminodia subulate. Anther acute. (Name from oplos, straight, and xepas, a horn.) 
1. Orthoceras Solandri, Lindl.; caule erecto, folio filiformi longe vaginato, spica flexuosa 4—8-flora, 
bracteis acuminatis florem superantibus, petalis parvis lineari-oblongis bifidis, labello 3-lobo basi 2-glan- 
duloso, staminodiis subulatis, anthera mutica. Lindley, Gen. et Sp. Orchid. O. strictum, 4. Cunn. Prodr.

Has. Northern and Middle Islands, abundant in clay soil, Banks and Solander, etc. ^ Ascends to 
4000 feet at Nelson, Bidwill. Nat. name, “ Makaika,” Colenso. 
Gen. VIII. THELYMITRA, Forst. 
Perianthii foliola omnia conformia. Labellwm sessile, conforme. Columna bifida; anthera postica 
stigmateque clinandrio petaloideo inclusa, lobis lateralibus (staminodiis) penicillatis v. nudis. Podlinia 4, 
stigmatis glandule affixa.—Herbe Zerrestres ; caule foliato. 
Terrestrial herbs, natives of Australia, Tasmania, and New Zealand. Zuders oblong, with long fibres at the 
crown. Stem erect, sheathed at the base, and with one generally long leaf. Flowers few, spiked, large. Sepals, 
Petals, and Labellum all similar, the latter sessile. Anther posticous and stigma hid in the hooded column, which 
is made up of column and connate staminodia; the latter project, and are often terminated by tufts of hairs.—The 
New Zealand species are so very difficult to distinguish specifically, that it is probable that all belong to one very 
variable form. I find all gradations in colour, size, breadth of sepals and petals, and in the development of stami- 
nodia; the species here described are hence perhaps only marked states. From Mr. Edgerley’s note I find that he 
found the most dissimilar forms connected by intermediate ones. (Name from 6yAvperpa, in Greek, in allusion to 
the hooded column capping the anther.)
