Description
Diuris picta is a tuberous, perennial herb with between three and five leaves at its base, each leaf 80–150 mm (3–6 in) long and 2–4 mm (0.08–0.2 in) wide. Up to eight creamy-white to yellow flowers with brownish purple markings, 20–30 mm (0.8–1 in) long and 12–15 mm (0.5–0.6 in) wide are borne on a flowering stem 200–350 mm (8–10 in) tall. The dorsal sepal curves upwards, 15–20 mm (0.6–0.8 in) long and 9–11 mm (0.35–0.43 in) wide. The lateral sepals are 18–22 mm (0.7–0.9 in) long, 3–4 mm (0.1–0.2 in) wide and turned downwards. The petals are more or less erect or turned backwards, spread widely apart from each other, 13–17 mm (0.5–0.7 in) long and 9–11 mm (0.35–0.43 in) wide on a dark green stalk 4–7 mm (0.2–0.3 in) long. The labellum is 15–18 mm (0.6–0.7 in) long and has three lobes. The centre lobe is broadly egg-shaped, 12–15 mm (0.5–0.6 in) long and wide and the side lobes are 6–9 mm (0.2–0.4 in) long and 4–6 mm (0.16–0.24 in) wide.
