Australian orchid (Habenaria propinquior)
Description
Habenaria propinquior is a tuberous, perennial herb with between two and four leaves at the base of the plant, the leaves 40–80 mm (2–3 in) long and 8–15 mm (0.3–0.6 in) wide. Between ten and thirty white flowers 12–14 mm (0.5–0.6 in) long and 10–12 mm (0.39–0.47 in) wide are borne on a flowering stem 200–400 mm (8–20 in) tall. The dorsal sepal and petals overlap at their bases and form a hood over the column. The dorsal sepal is about 5 mm (0.2 in) long and 4.5 mm (0.2 in) wide and the lateral sepals are slightly longer and spread apart from each other. The petals are a similar length to the sepals but narrower. The labellum has three thread-like lobes 5–7 mm (0.20–0.28 in) long with the side lobes curving upwards. The nectary spur is 10–12 mm (0.39–0.47 in) long and slightly curved. Flowering occurs between January and April.
