Small duck orchid, flying duck orchid

Native to eastern Australia and northern New-Zealand.

It is a tuberous, perennial herb with a single reddish brown, linear leaf, 40–130 mm long, 1–3 mm wide and folded lengthwise. The leaf is usually withered by flowering time. Up to four yellowish green to reddish brown flowers, 14–16 mm (0.55–0.63 in) long and 5–7 mm wide are borne on a flowering stem 80–150 mm tall. The sepals and petals are 7–10 mm long, 1–2 mm wide and hang downwards forming a bucket-like shape with the broad wings of the column.

The labellum is 5–6 mm long, 3–4 mm wide, covered with glossy black glands and held above the flower on a sensitive strap-like stalk about 5 mm long.

Flowering occurs from September to February although the flowering period is shorter in New Zealand.
