Bulbophyllum trichorhachis

A tiny creeping Bulbophyllum from Sulawesi, with a thread-thin rhizome, leaves under 2 cm long and zig-zag racemes of up to 22 all-purple flowers that open one after another. It was described in 2003 from a single plant, an epiphyte on medium-sized trees in montane forest at about 1000 m. Treat it as an intermediate, humid, mounted species; almost nothing else is known about its ecology.
