Bulbophyllum grandimesense

Pale rope orchid

A small, rope-like epiphytic Bulbophyllum from the Cedar Bay area of north-east Queensland. Its branching stems, 10–20 cm long and covered in brown bracts, carry well-spaced pseudobulbs, each with a single dark green leaf. Small white flowers, 6–8 mm long, appear in May and June. It lives high on the upper branches of rainforest trees at 500–800 m, so it wants bright, airy, humid conditions with warm days and mild nights.
