Up to eight pale to deep mauve, sometimes pink flowers, without spots or stripes, 15–20 mm (0.6–0.8 in) wide are borne on a flowering stem sometimes up to 600 mm (20 in) tall. The arms on the sides of the column have prominent, dense tufts of orange or yellow, rarely white or pink hairs. The lobe on top of the anther is usually dark red with two pointed yellow tips.

Taxonomy and naming

Thelymitra hatchii was first formally described in 1968 by Lucy Moore from a plant she collected near Oxford and the description was published in New Zealand Journal of Botany.[1][4] The specific epithet (hatchii) honours the New Zealand botanist, Edwin Daniel Hatch.[4]

Distribution and habitat

This thelymitra usually grows in open areas near scrubland or bogs. It is found on the North, South and Stewart Islands.[2][3]
