Flora of New Zealand Series

T. imberbis Hook. f. Fl. N.Z.  1,  1853,  244.

T. carnea var. imberbis (Hook. f.) Rupp et Hatch in Proc. Linn. Soc. N.S.W. 70, 1946, 59.

Type locality: Near Port Jackson, N.S.W. Recorded also from Victoria and S. Australia.

Plant at fl. 15–30 cm. tall, often reddish. Lf narrow-linear, almost terete to shallowly channelled. Infl. 1–3–(6) -fld. Per. c. 8–10 mm. long, from cream to pink, without stripes or spots. Sepals and petals alike, broadly oblong. Labellum often slightly smaller. Column-arms ± ovate, thick and fleshy, marginally crenate but without fringes or cilia; post-anther lobe almost as high as anther, erect, margins fleshy, unevenly thickened to almost cucullate, bright yellow.

DIST.: N. Apparently mostly north of lat. 39º. S. Oxford (CheesemanAK 3391); Collingwood-Takaka district.

In short open vegetation.

FL. 9–11.

T. imberbis. Original locality: "Bay of Islands, etc. Colenso, Sinclair, etc." Type: K(?). The per. was described as yellow, and the column-arms as "Apice crenatis v. obscure fimbriatis". Rupp and Hatch reduced Hooker's sp. to varietal rank "with some hesitation", some N.Z. specimens being more robust than the Australian ones, and the column stouter; but they state that the morphology of the fls is almost identical. Willis (Handbk Pl. Vict. 1962, 354) accepts the N.Z. plant as T. carnea.
