Bulbophyllum wadsworthii
The yellow rope orchid is a tiny Wet Tropics endemic that forms hanging, rope-like clumps of 5–6 mm cylindrical pseudobulbs, each with a single dark green leaf. It grows on trees and rocks in upland rainforest of northeast Queensland, and sometimes on treefern trunks and paddock trees, which shows it takes more light and exposure than many small Bulbophyllum. Single cream to pale green star-shaped flowers with an orange lip appear from September to November.
Where it grows wild
It hangs from trunks, branches and rock faces in rainforest, and also persists on treeferns and on trees left standing in cleared paddocks. These are bright, airy positions that dry quickly between the frequent mists and showers of the tablelands.
