The lobe on top of the anther is short and covered with small bumps.

The flowers are self-pollinated and open on hot, sunny days.

[2][3][4][5] Thelymitra tigrina was first formally described in 1810 by Robert Brown and the description was published in Prodromus Florae Novae Hollandiae et Insulae Van Diemen.

[6][7] The specific epithet (tigrina) is a Latin word meaning "of tigers",[8] referring to the colour of the flowers.

It is found between Perth and Albany with a disjunct population near Esperance.
