Diuris abbreviata, commonly known as the lemon doubletail,[2] is a species of orchid that is endemic to eastern Australia. It has two or three leaves and a flowering stem with up to nine yellow flowers with darker markings.
Diuris abbreviata is a tuberous, perennial herb with two or three linear leaves 120–250 mm (5–10 in) long, 3–4 mm (0.1–0.2 in) wide and folded in half lengthwise. There are between three and nine pale to bright yellow flowers with darker markings which lean forwards and are about 25 mm (1 in) wide. The dorsal sepal is egg-shaped, 7–12 mm (0.3–0.5 in) long, 5–8 mm (0.2–0.3 in) wide and more or less erect. The lateral sepals are linear to lance-shaped, 11–16 mm (0.4–0.6 in) long, 1–3 mm (0.04–0.1 in) wide, and turn downwards. The petals are erect, ear-like above the flower, 7–14 mm (0.3–0.6 in) long and 4.5–9 mm (0.2–0.4 in) wide on a brownish, stalk-like "claw" 3–6 mm (0.1–0.2 in) long. The labellum is 7–14 mm (0.3–0.6 in) long and has three lobes. The centre lobe is broad egg-shaped, about 8 mm (0.3 in) wide with a ridge along its mid-line. The lateral lobes are narrow linear to triangular in shape, 2–4 mm (0.08–0.2 in) long and 1–1.5 mm (0.04–0.06 in) wide. There are two ridge-like calli about 5 mm (0.2 in) long near the mid-line of the labellum. Flowering occurs from September to November.[2]
