Taxonomy and naming
Thelymitra pulchella was first formally described in 1853 by Joseph Dalton Hooker and the description was published in Flora Novae-Zelandiae. The specific epithet (pulchella) is the diminutive form of the Latin word pulcher meaning "beautiful". Hooker described this species as "very handsome".
