Detailed description
Terrestrial, tuberous, glabrous, late winter to early summer-green perennial herb, either solitary or in well-spaced groups. Plants mostly reddish-green, at flower 100–300 mm tall. Leaf solitary, wiry, distinctly flexuose, fleshy to subcoriaceous, 80–160 × 2.5–3.0 mm, dark green to reddish green, terete or semi-terete and shallowly channelled, apex often twisted, subacute, often frayed. Inflorescence a 1–8-flowered raceme. Flowers widely spaced, 8–14 mm diameter, segments to 8 × 4 mm, mostly pink, rarely cream or pale lemon yellow with the sepals darker coloured than the petals, without spots or stripes, scarcely opening or not, if opening only slightly spreading. Sepals and petals alike, broadly oblong. Labellum very slightly smaller. Column to 4 mm long, cream to pale pink or dark pink; column arms obliquely erect, more or less ovate, thick, fleshy, margins crenate or toothed, rarely with a few small spheroidal glands, otherwise without further ornamentation or cilia; post-anther lobe almost as high as anther, erect, margins fleshy, unevenly thickened to very slightly cucullate, weakly notched, bright yellow. Anther not prominent.
Similar taxa
Not likely to be confused with anyother indigenous species. This species is readily identified by the reddish colour of the stem and leaf, and the slender, zig-zagged (flexuose) terete to semi-terete leaf (usually with a twisted and distinctly frayed apex). The widely spaced mostly pink flowers which scarcely open, are also distinctive. While the small pink grading to yellow, scarcely hooded and notched column, and flattened, toothed column arms lacking cilia are also unusual in New Zealand Thelymitra.
Distribution
Indigenous. New Zealand: North Island (mainly northern to about Taupo, local around the southern North Island, apparently absent in between), South Island (confined to the northern third, mainly in the west).
Habitat
Coastal to montane (up to 700 m a.s.l.). Mostly at low elevations and favouring open clay pans, consolidated sand hollows, and geothermal ground. Sometimes on the margins of peat bogs. Most often in gumland scrub or other semi-permanent shrubland habitats where it is especially abundant after fire.
Current conservation status
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2022-2023 using the New Zealand Threat Classification System (NZTCS) – more information about this can be found on the NZTCS website. This report includes replaces all previous NZTCS lists for vascular plants. Previous assessments can be found here.
Please note, threat classifications are often suggested by authors when publications fall between NZTCS assessment periods – these interim threat classification statuses has not been assessed by the NZTCS panel.

Threats
Not Threatened. However, it has declined from large parts of its range through habitat loss to taller forest or through urban development. Still abundant in the far north but if trends continue it may qualify in the not too distant future for a worse conservation status.

Taxonomic notes
Thelymitra carnea is based on an Australian type. Australian plants tend to be slightly larger than New Zealand forms and often have cream or reddish coloured flowers. Some people regard the New Zealand plant as endemic and use the name T. imberbis Hook.f. for it.
