Chiloglottis sphyrnoides

Chiloglottis sphyrnoides is a terrestrial, perennial, deciduous, herb with two egg-shaped to elliptic leaves 35–85 mm (1–3 in) long and 15–23 mm (0.6–0.9 in) wide on a petiole 5–15 mm (0.2–0.6 in) long. A single green or reddish pink flower 18–22 mm (0.7–0.9 in) long and 7–9 mm (0.3–0.4 in) wide is borne on a flowering stem 50–90 mm (2–4 in) high. The dorsal sepal is spatula-shaped, 16–18 mm (0.6–0.7 in) long and 3–4 mm (0.1–0.2 in) wide. The lateral sepals are linear, 13–17 mm (0.5–0.7 in) long, about 1 mm (0.04 in) wide and curve downwards. There is a glandular tip 2–2.5 mm (0.08–0.1 in) long on the end of the dorsal sepal and 4–6 mm (0.16–0.24 in) long on the lateral sepals. The petals are narrow oblong, 11–13 mm (0.4–0.5 in) long, about 4 mm (0.2 in) wide and turn downwards towards the ovary. The labellum is broadly spatula-shaped, 10–12 mm (0.4–0.5 in) long and 7–8.5 mm (0.28–0.33 in) wide. There is a shiny black, insect-like callus about 2 mm (0.08 in) long and wide near the base of the labellum. This large callus is surrounded by reddish, club-shaped calli and small red calli. The column is green with purplish black blotches, 9–10 mm (0.35–0.39 in) long and about 4 mm (0.2 in) wide with narrow wings. Flowering occurs from December to April.^[2][3][4]
