Description

Corybas barbarae is a terrestrial, perennial, deciduous, herb with a single heart-shaped to almost round leaf 16–32 mm (0.6–1 in) long and 18–36 mm (0.7–1 in) wide. The leaf is dark green or reddish green on the upper surface and silvery green to light reddish purple on the lower side. There is a single sparkling white or pinkish flower 30–35 mm (1.2–1.4 in) long and 15–20 mm (0.6–0.8 in) wide which leans downwards. The largest part of the flower is the dorsal sepal which is curved and inflated, 27–32 mm (1–1 in) long and 15–20 mm (0.6–0.8 in) wide. The lateral sepals are linear, about 2 mm (0.08 in) long, and turn upwards towards the base of the labellum. The petals are about 1 mm (0.04 in) long and hidden by the labellum. The labellum is mostly hidden by the dorsal sepal, tube shaped near its base, about 12.5 mm (0.5 in) long, 7 mm (0.3 in) wide, translucent white and hairy. Flowering occurs from March to July.[2][3][4]
