Description

Chiloglottis gunnii is a terrestrial, perennial, deciduous, herb with two leaves 40–60 mm (1.6–2.4 in) long and 15–20 mm (0.6–0.8 in) wide. A single green to purplish brown flower 20–24 mm (0.79–0.94 in) long and 20–25 mm (0.8–1 in) wide is borne on a flowering stem 60–100 mm (2–4 in) high. The dorsal sepal is egg-shaped to spatula-shaped with the narrower end towards the base, 20–24 mm (0.8–0.9 in) long and 7–11 mm (0.3–0.4 in) wide. The lateral sepals are linear to lance-shaped, 15–20 mm (0.6–0.8 in) long, about 2 mm (0.08 in) wide and taper towards their tips. There is a glandular tip 0.5–1.5 mm (0.02–0.06 in) long on the end of all three sepals. The petals are lance-shaped but curved, 15–17 mm (0.6–0.7 in) long, 4.5–6 mm (0.18–0.24 in) wide and spread widely apart from each other. The labellum is broadly egg-shaped to heart-shaped, 10–13 mm (0.4–0.5 in) long and 10–15 mm (0.4–0.6 in) wide with a line of pillar-like calli about 3 mm (0.1 in) high with large swollen heads up to 2 mm (0.08 in) wide. The column is 15–18 mm (0.6–0.7 in) long and 5–6 mm (0.20–0.24 in) wide and curved with narrow wings. [2] [3]

Taxonomy and naming

Chiloglottis gunnii was first formally described in 1840 by John Lindley and the description was published in his book The Genera and Species of Orchidaceous Plants . [4] [5] The specific epithet (gunnii) honours Ronald Campbell Gunn, who collected the type specimen which was sent to William Jackson Hooker who forwarded it to Lindley. [5] [6]

Distribution and habitat

The tall bird orchid is widespread but uncommon, growing mostly in wet forest and coastal scrub. [2] [3]
