Upper sepal ovate, acute, concave; lateral rather longer, lanceolate, quite free. Petals linear-oblong, obtuse. Lip sessile, as long as the sepals, erect at the base and then suddenly reflexed between the lateral sepals; adnate plate narrower than the disc and not extending much further up than the flexure of the lip; margins broad, thin, undulate. Column short; lateral lobes linear-oblong, obtuse, almost as long as the narrow erect rostellum, entire. Anther large, pointed, not quite equalling the rostellum.—''Hook. f. Fl. Tasm.'' ii. 11, t. 111; ''Benth. Fl. Austral.'' vi. 339.

2. P. Colensoi, Hook. f. Fl. Nov. Zel. i. 241.—Stem stout or slender, erect, 4–14 in. high. Leaf sheathing the stem for three-quarters its length or even more; lamina shorter than the spike or equalling it. Spike 1–3 in. long, many-flowered; bracts as short as the pedicel, broad, obtuse. Flowers about ⅕ in. long, dull-green or greenish-brown, slightly fragrant; ovary obovoid, gibbous. Upper sepal ovate-oblong, acute, concave; lateral rather longer, connate at the very base, lanceolate, acute, curved backwards. Petals linearoblong, obtuse. Lip shorter than the sepals, sessile, ovate, tip acuminate, shortly recurved, adnate plate extending almost to the tip, margins undulate. Column very short, lateral lobes broadly notched, shorter than the rostellum. Anther broad, obtuse, not equalling the rostellum,—''Handb. N.Z. Fl.'' 272. (?) P. pauciflorum, Col. in Trans. N.Z.
