Description
Diuris heberlei is a tuberous, perennial herb with between three and five linear leaves at its base, each leaf 100–150 mm (4–6 in) long and 2–3 mm (0.08–0.1 in) wide. Up to five bright yellow flowers 30–35 mm (1.2–1.4 in) wide are borne on a flowering stem 200–500 mm (8–20 in) tall. The dorsal sepal is more or less erect, narrow egg-shaped with a tapered tip, 12–16 mm (0.5–0.6 in) long and 7–9 mm (0.3–0.4 in) wide. The lateral sepals are linear to sword-shaped, greenish brown, 18–24 mm (0.7–0.9 in) long, 4–5 mm (0.16–0.20 in) wide, turned downwards and parallel to each other. The petals are more or less erect or turned backwards, spread apart from each other, 11–16 mm (0.4–0.6 in) long and 8–11 mm (0.3–0.4 in) wide on a brownish or blackish stalk 6–8 mm (0.2–0.3 in) long. The labellum is 12–18 mm (0.5–0.7 in) long and has three lobes. The centre lobe is broadly egg-shaped, 10–13 mm (0.4–0.5 in) wide with a low ridge with brown markings near its base. The side lobes are egg-shaped, 6–10 mm (0.2–0.4 in) long and 4–7 mm (0.2–0.3 in) wide. There are two ridge-like calli about 8 mm (0.3 in) long near the mid-line of the base of the labellum and bordered with reddish brown. Flowering occurs between late December and February.
