Bulbophyllum shepherdii, commonly known as the wheat-leaf rope orchid,[2] is a species of epiphytic or lithophytic orchid that forms a dense mat of branching rhizomes pressed against the surface on which it grows. The pseudobulbs are well spaced along the rhizome, each with a single egg-shaped leaf and a single small, white or cream-coloured flower with yellow tips. It grows on trees and rocks in rainforest and is endemic to eastern Australia .
Description
Bulbophyllum shepherdii is an epiphytic or lithophytic herb with branching rhizomes forming a dense mat on the substrate. The pseudobulbs are more or less spherical but flattened 2–3 mm (0.08–0.1 in) in diameter separated by 2–9 mm (0.08–0.4 in). Each pseudobulb has a grooved, stalkless, elliptic to egg-shaped leaf 20–40 mm (0.8–2 in) long and 6–8 mm (0.24–0.31 in) wide with a channelled upper surface. A single white or cream-coloured flower with yellow tips, 4–5 mm (0.16–0.20 in) long and 2–3 mm (0.079–0.12 in) wide is borne on a flowering stem 5–9 mm (0.2–0.4 in) long. The flowers do not open widely. The sepals and petals are fleshy, the sepals 4–5 mm (0.16–0.20 in) long, about 2 mm (0.08 in) wide and the petals about 2 mm (0.08 in) long and 1.5 mm (0.06 in) wide. The labellum is reddish brown, about 2 mm (0.08 in) long and 1 mm (0.04 in) wide with smooth edges and a sharp bend near the middle. Flowering occurs from March to August.[2][3]
Taxonomy and naming
The wheat-leaf rope orchid was first formally described in 1859 by Ferdinand von Mueller who published the description in Fragmenta phytographiae Australiae from a specimen collected by T.W. Shepherd.[4][5] In 1870 Heinrich Gustav Reichenbach changed the name to Bulbophyllum shepherdii.[6] The specific epithet (shepherdii) honours Thomas William Shepherd who collected the type specimen.[7]
Distribution and habitat
Bulbophyllum shepherdii grows on trees and rocks in rainforest and wet forest between Nambour in Queensland and Bega in New South Wales.[2][3]
