Description
Diuris parvipetala is a tuberous, perennial herb with two linear leaves 200–300 mm (8–10 in) long, 3–4 mm (0.1–0.2 in) wide and folded lengthwise. Up to nine whitish to mauve flowers with purple markings and 17–22 mm (0.7–0.9 in) wide are borne on a flowering stem 200–450 mm (8–20 in) tall. The dorsal sepal is angled upwards, 6–8 mm (0.2–0.3 in) long and about 5 mm (0.2 in) wide. The lateral sepals are 30–45 mm (1–2 in) long, about 1 mm (0.04 in) wide and turned downwards. The petals are oblong, 3–4 mm (0.1–0.2 in) long, 1–2 mm (0.04–0.08 in) wide and spread apart from each other on a purple-brown stalk 6–8.5 mm (0.2–0.3 in) long. The labellum is 5–6.5 mm (0.2–0.3 in) long and has three lobes. The centre lobe is spade-shaped, about 5 mm (0.2 in) long and 4–5 mm (0.16–0.20 in) wide with its tip turned downwards. The side lobes are about 2 mm (0.08 in) long and 1 mm (0.04 in) wide. There are between two thick, ridge-like calli 3–4 mm (0.1–0.2 in) long in the mid-line of the labellum.
