Description

Chiloglottis diphylla is a terrestrial, perennial, deciduous, herb with two leaves 30–60 mm (1–2 in) long and 10–15 mm (0.4–0.6 in) wide. A single greenish brown to reddish flower 30–45 mm (1–2 in) long and 4–5 mm (0.16–0.20 in) wide is borne on a flowering stem 70–100 mm (3–4 in) high. The dorsal sepal is spatula-shaped, 12–14 mm (0.5–0.6 in) long and about 2 mm (0.08 in) wide with a glandular tip a further 3–4 mm (0.1–0.2 in) long. The lateral sepals are 15–22 mm (0.6–0.9 in) long, about 0.5 mm (0.02 in) wide and curve downwards. There is a glandular tip 7–10 mm (0.3–0.4 in) long on the end of each lateral sepal. The petals are oblong, 7–9 mm (0.3–0.4 in) long, about 2 mm (0.08 in) wide and turned strongly downwards. The labellum is diamond-shaped, 7–10 mm (0.3–0.4 in) long and 4–5 mm (0.16–0.20 in) wide with a black, insect-like callus covering most of its upper surface. Flowering occurs from February to May.
