Corunastylis tepperi, commonly known as pygmy orchid, is the only species in the flowering plant genus Corunastylis in the orchid family, Orchidaceae and is native to Victoria, South Australia and Western Australia. It is a terrestrial herb with a single leaf mostly surrounding the stem and up to 50 flowers. The flowers are tiny with a deep maroon-coloured labellum and often have a fruity fragrance.
Corunastylis tepperi is a terrestrial, perennial, deciduous, sympodial herb. A single long leaf surrounds the stem from the base of the plant to the lowest of the flowers. The leaf is 8–20 cm (3–8 in) long and 1–2 mm (0.04–0.08 in) wide.
The inflorescence is a spike with from 5 to 50 crowded, tiny, non-resupinate flowers which are bright green with a dark maroon-coloured to purplish-black labellum. Each flower is , about 3 mm (0.1 in) wide and long with petals and sepals that do not spread widely. The sepal is a broad egg-shape, about 2 mm (0.08 in) long and wide. The two sepals are lance-shaped, 2.5–3.5 mm (0.098–0.14 in) long and about 1 mm (0.04 in) wide and dished near their base. The petals are egg-shaped, about 2 mm (0.08 in) long and less than 1 mm (0.04 in) wide. The dark-coloured labellum is egg-shaped, about the same size as the petals with a minutely wavy edge. The callus is narrow egg-shaped and extends almost to the tip of the labellum. The column, which is below the labellum has wings with a rough surface. Flowering occurs between February and May and the fruit that follows is a non-fleshy, dehiscent capsule containing hundreds of seeds.
