Thelymitra exigua

Thelymitra exigua is a tuberous, perennial herb with a single fleshy, channelled, dark green, linear to lance-shaped leaf 50–220 mm (2–9 in) long and 2.5–10 mm (0.1–0.4 in) wide with a purplish base. Up to eight pale blue to pale purplish blue flowers 13–22 mm (0.5–0.9 in) wide are borne on a flowering stem 100–300 mm (4–10 in) tall. The sepals and petals are 5–11 mm (0.2–0.4 in) long and 3–6 mm (0.1–0.2 in) wide. The column is pale pink to pale purplish, 4–6 mm (0.16–0.24 in) long and 2–3 mm (0.08–0.1 in) wide. The lobe on the top of the anther is gently curved and dark brown to black with a yellow tip. The side lobes curve upwards near their middle and have toothbrush-like tufts of white hairs covering their tops. The flowers are self-pollinating, only open on warm to hot sunny days and then only slowly if at all. Flowering occurs from September to November.

Short sun orchid grows in grassland, heath and shrubland. It is found in western Victoria, south-eastern South Australia and in Tasmania, including on King Island.
