Chiloglottis longiclavata, commonly known as the northern wasp orchid,[2] is a species of orchid endemic to Queensland. It has two leaves and a single narrow, pinkish green flower with a dark blackish red callus covering most of the upper surface of the labellum .
Chiloglottis longiclavata is a terrestrial, perennial, deciduous, herb with two elliptic leaves 25–60 mm (1–2 in) long and 10–20 mm (0.4–0.8 in) wide on a petiole 3–5 mm (0.1–0.2 in) long. A single pinkish green flower 20–25 mm (0.8–1 in) long and 5–6 mm (0.20–0.24 in) wide is borne on a flowering stem 70–100 mm (3–4 in) high. The dorsal sepal is narrow egg-shaped to elliptic with a narrow base, 15–18 mm (0.6–0.7 in) long and about 2.5 mm (0.1 in) wide. The lateral sepals are linear but tapered, 12–15 mm (0.5–0.6 in) long, about 1 mm (0.04 in) wide and erect near the base before curving downwards and spreading apart from each other. There is a glandular tip 4–9 mm (0.2–0.4 in) long on the dorsal sepal and 10–14 mm (0.4–0.6 in) long on the lateral sepals. The petals are lance-shaped to oblong, 7–8 mm (0.28–0.31 in) long, about 2.5 mm (0.1 in) wide and turn downwards against the ovary. The labellum is broadly egg-shaped to diamond-shaped, 7–8 mm (0.28–0.31 in) long and 4–5 mm (0.16–0.20 in) wide. Most of the upper surface of the labellum is covered by a dark blackish red, insect-like callus of stalked and clusters of stalkless glands. The column is pale green with purple flecks, about 6 mm (0.2 in) long, about 2.5 mm (0.1 in) wide with narrow wings. Flowering occurs from February to May.[2][3][4]
