highland golden moths

Diuris monticola is a tuberous, perennial herb with between five and nine narrow linear leaves 50–200 mm (2–8 in) long and 3–4 mm (0.1–0.2 in) wide in a loose tuft. Up to four slightly drooping bright yellow flowers with dark streaks in the centre and 15–28 mm (0.6–1 in) wide are borne on a flowering stem 150–350 mm (6–10 in) tall. The dorsal sepal leans forward and is egg-shaped, 9–12 mm (0.4–0.5 in) long and 7–9 mm (0.3–0.4 in) wide. The lateral sepals are lance-shaped to egg-shaped, the narrower end towards the base, 15–25 mm (0.6–1 in) long, 2.5–4.5 mm (0.1–0.2 in) wide, lean downwards and parallel to each other. The petals are egg-shaped, 7–13 mm (0.3–0.5 in) long, 4–9 mm (0.2–0.4 in) wide and spread apart from each other on a blackish stalk 3–5.5 mm (0.1–0.2 in) long. The labellum is 12–17 mm (0.5–0.7 in) long and has three lobes. The centre lobe is egg-shaped, 7–13 mm (0.3–0.5 in) long and 6–12 mm (0.2–0.5 in) wide and the side lobes are linear to narrowly wedge-shaped, 2–3.5 mm (0.08–0.1 in) long and 1–2 mm (0.04–0.08 in) wide with irregular edges. There are two pimply, darker yellow callus ridges in the lower part of the mid-line of the labellum. Flowering occurs from November to January.

Highland golden moths is widespread and common in montane grassland, and snowgum woodland in the higher parts of southern New South Wales, Tasmania, the Australian Capital Territory and north-eastern Victoria.
