Description
Diuris punctata is a tuberous, perennial herb with two linear leaves 150–300 mm (6–10 in) long, 3–4 mm (0.1–0.2 in) wide and folded lengthwise. Up to ten flowers 50–60 mm (2.0–2.4 in) wide are borne on a flowering stem 300–600 mm (10–20 in) tall. The flowers are purple or mauve, often with darker, sometimes yellow marks. The dorsal sepal is more or less erect, elliptic to egg-shaped, 10–18 mm (0.4–0.7 in) long and 8–14 mm (0.3–0.6 in) wide. The lateral sepals are greenish-brown, linear to lance-shaped, 30–50 mm (1–2 in) long, 2–4 mm (0.08–0.2 in) wide and turned downwards. The petals are erect with an egg-shaped blade 7–17 mm (0.3–0.7 in) long and 7–15 mm (0.3–0.6 in) wide on a dark coloured stalk 2–6 mm (0.08–0.2 in) long. The labellum is 9–15 mm (0.4–0.6 in) long and has three lobes. The centre lobe is broadly egg-shaped to fan-shaped, 7–12 mm (0.3–0.5 in) long and 12–20 mm (0.5–0.8 in) wide and the side lobes are linear to wedge-shaped, 3–5 mm (0.1–0.2 in) long and 1.5–4 mm (0.06–0.2 in) wide. There are two ridge-like calli about 5 mm (0.2 in) long, surrounded by yellow in the mid-line of the labellum. Flowering occurs from September to December.
