Bulbophyllum argyropus
Introduction '''''Bulbophyllum argyropus''''', commonly known as the '''silver strand orchid''',  is a species of epiphytic or sometimes lithophytic orchid that is endemic to eastern Australia, including Lord Howe and Norfolk Islands. It has crowded pseudobulbs, tough, dark green leaves and up to four small whitish to yellowish flowers with an orange labellum.
Description ''Bulbophyllum argyropus'' is an epiphytic, rarely an lithophytic herb with crowded, warty and furrowed pseudobulbs  long and  wide. Young pseudobulbs are covered with papery white bracts. There is a single tough, dark green leaf,  long and  wide on each pseudobulb. Up to five whitish or yellowish flowers  long and about  wide are arranged on a warty, thread-like flowering stem  long. The sepals are about  long and  wide, the lateral sepals are  long, the petals about  long and wide. The labellum is orange, about  long and  wide curved and fleshy. Flowering occurs between August and December.
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''. In 1876, Heinrich Gustav Reichenbach changed the name to ''Bulbophyllum argyropus''. The specific epithet (''argyropus'') is derived from the Ancient Greek words ''argyros'' meaning "silver" and ''pous'' meaning "foot".
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.
