Peppertop Sun-orchid

Thelymitra brevifolia is a tuberous, perennial herb with a single erect, dark green, linear to lance-shaped leaf 100–260 mm (4–10 in) long and 7–20 mm (0.3–0.8 in) wide often with reddish blotches. Between two and twenty purplish or purplish blue flowers 12–22 mm (0.5–0.9 in) wide are arranged on a flowering stem 250–600 mm (10–20 in) tall. The sepals and petals are 6–12 mm (0.2–0.5 in) long and 3–6 mm (0.1–0.2 in) wide. The column is pale blue or pale pink, 4–5.5 mm (0.16–0.22 in) long and 2–3 mm (0.08–0.1 in) wide. The lobe on the top of the anther varies in colour from yellow to black with a yellow tip and is scarcely inflated. The side lobes curve gently upwards and have mop-like tufts of white hairs. Flowering occurs from September to November but the flowers are self-pollinating and only open on hot days, and then only slowly.

Peppertop sun orchid is widespread and locally common in the south-east of New South Wales, in Victoria, the Australian Capital Territory, south-eastern South Australia and on the north and east coasts of Tasmania. It grows in a wide range of habitats from heath to forest and woodland, often growing in disturbed sites.
