Description

Bulbophyllum argyropus is an epiphytic, rarely an lithophytic herb with crowded, warty and furrowed pseudobulbs 5–8 mm (0.2–0.3 in) long and 4–6 mm (0.16–0.24 in) wide. Young pseudobulbs are covered with papery white bracts. There is a single tough, dark green leaf, 20–45 mm (0.8–2 in) long and 4–6 mm (0.16–0.24 in) wide on each pseudobulb. Up to five whitish or yellowish flowers 5–6 mm (0.20–0.24 in) long and about 4 mm (0.16 in) wide are arranged on a warty, thread-like flowering stem 15–30 mm (0.59–1.2 in) long. The sepals are about 4 mm (0.2 in) long and 1 mm (0.039 in) wide, the lateral sepals are 14–18 mm (0.55–0.71 in) long, the petals about 1 mm (0.039 in) long and wide. The labellum is orange, about 3 mm (0.12 in) long and 2 mm (0.079 in) wide curved and fleshy. Flowering occurs between August and December.[2][3][4][5]

Taxonomy and naming

The silver strand orchid was first formally described in 1833 by Stephan Endlicher who gave it the name Thelychiton argyropus and published the description in Prodromus Florae Norfolkicae.[6][7] In 1876, Heinrich Gustav Reichenbach changed the name to Bulbophyllum argyropus.[8] The specific epithet (argyropus) is derived from the Ancient Greek words argyros meaning "silver"[9]:712 and pous meaning "foot".[9]:343

Distribution and habitat

Bulbophyllum argyropus usually grows on the highest branches of rainforest trees, rarely on rocks. It occurs between the McPherson Range in Queensland and the Dorrigo Plateau in New South Wales as well as on Lord Howe and Norfolk Islands. It has also been reported from New Caledonia.[2][3][4][10]

gollark: Hmm, that is actually quite good.
gollark: As "the definite article", typically.
gollark: They never define stuff like "the" without just using the words.
gollark: That's mostly just recursive.
gollark: I assumed you were talking about religion there initially given the phrasing, which I do consider to involve horrible punishment for dubious ethical reasons. But in general it seems to basically just mean "punishment", with connotations of "in accordance with some allegedly fair procedure(s)".
