Genoplesium trifidum

Genoplesium trifidum is a terrestrial, perennial, deciduous, herb with an underground tuber and a single thin leaf 200–300 mm (8–10 in) long and fused to the flowering stem with the free part 15–20 mm (0.6–0.8 in) long. Between five and twenty five dark purplish-black and green flowers are arranged along a flowering stem 10–30 mm (0.4–1 in) long. The flowers lean downwards slightly and are 3–4 mm (0.12–0.16 in) long and 4–5 mm (0.16–0.20 in) wide. As with others in the genus, the flowers are inverted so that the labellum is above the column rather than below it. The dorsal sepal is 2–2.5 mm (0.08–0.1 in) long and about 1.5 mm (0.06 in) wide with hairless edges and darker coloured bands. The lateral sepals are about 3 mm (0.1 in) long and about 1 mm (0.04 in) wide, with a humped base and a sharply pointed tip. The petals are about 1.5 mm (0.06 in) long and about 1 mm (0.04 in) wide with hairless edges and a sharply pointed tip. The labellum is egg-shaped, about 3 mm (0.1 in) long and 1.5 mm (0.06 in) wide, thick and fleshy. There is a broad, tapering callus in the centre of the labellum and extending nearly to its tip. Flowering occurs from January to April.

Genoplesium trifidum grows in heath or heathy forest between Kurri Kurri and Middle Harbour.
