Saccolabiopsis armitii, commonly known as the spotted pitcher orchid,[2] is an epiphytic orchid from the family Orchidaceae. It has a short stem, coarse, wiry roots, between three and six crowded, curved leaves and up to fifty yellowish green flowers with red markings and a white labellum. It usually grows in coastal scrub to rainforest in New Guinea and tropical North Queensland, Australia.

Description

[edit]

Saccolabiopsis armitii is an epiphytic herb with a single main growth, coarse wiry roots and a stem 20–50 millimetres (0.79–2.0 in) long. There are between three and six crowded, curved leaves 30–60 millimetres (1.2–2.4 in) long and 10–12 millimetres (0.39–0.47 in) wide with a prominent midrib on the lower surface. Between twenty and fifty cup-shaped, resupinate, yellowish green flowers with red markings 5–7 millimetres (0.20–0.28 in) long and 3–5 millimetres (0.12–0.20 in) wide are arranged on a pendulous flowering stem 50–90 millimetres (2.0–3.5 in) long. The dorsal sepal is about 2 millimetres (0.079 in) long, 1 millimetre (0.039 in) wide and the lateral sepals are a similar width but longer. The petals are about 1 millimetre (0.039 in) long and wide. The labellum is white, about 2 millimetres (0.079 in) long and 1 millimetre (0.039 in) wide with three lobes and a red anther. The side lobes are triangular and the middle lobe is short and rounded. Flowering occurs from September to December.[2][3][4]

Taxonomy and naming

[edit]

The spotted pitcher orchid was first formally described in 1875 by Ferdinand von Mueller and given the name Sarcochilus armitii. The description was published in Fragmenta phytographiae Australiae.[5][6] In 1886, Frederick Manson Bailey changed the name to Saccolabiopsis armitii.[7] The specific epithet (armitii) honours William Armit who collected the type specimen.[8]

Distribution and habitat

[edit]

Saccolabiopsis armitii grows in coastal scrub and rainforest up to 150 kilometres (93 mi) from the coast. It is found in New Guinea and in Queensland between Weipa and Bundaberg.[2][3][4]
