Genoplesium baueri

Genoplesium baueri is a terrestrial, perennial, deciduous, herb with an underground tuber and a single thin leaf 40–120 mm (2–5 in) long, about 2 mm (0.08 in) wide with the free part 10–20 mm (0.4–0.8 in) long. Up to nine yellowish green to reddish brown flowers are crowded along a flowering stem 60–150 mm (2–6 in) tall and taller than the leaf. The flowers are 8–11 mm (0.3–0.4 in) long, 11–13 mm (0.4–0.5 in) wide and as with others in the genus, are inverted so that the labellum is above the column rather than below it. The dorsal sepal is a broad egg shape, about 3 mm (0.1 in) long, 4 mm (0.2 in) wide with a long thin tip and hairless edges. The lateral sepals are linear to lance-shaped, 8–10 mm (0.3–0.4 in) long, about 2 mm (0.08 in) wide, boat-shaped near the tip and spread widely apart. The petals are egg-shaped, pointed, about 3 mm (0.1 in) long and 1.5 mm (0.06 in) wide with hairless, sometimes notched edges. The labellum is narrow egg-shaped to lance-shaped, about 4 mm (0.2 in) long, 2 mm (0.08 in) wide with the edges rolled and hairless. There is a fleshy, raised, channelled callus in the centre of the labellum. Flowering occurs between December and April and is enhanced by fire the previous summer.

Genoplesium baueri grows in heath, woodland and forest, mostly in coastal and near-coastal areas. It has been recorded between Port Stephens and Ulladulla and as far inland as Woodford and Penrose State Forest.
