Bulbophyllum gadgarrense

Tangled rope orchid

A tiny epiphytic Bulbophyllum from the upland rainforests of the Wet Tropics in north Queensland. It forms tangled, branching, hanging stems 10–20 cm long with small grooved leaves and white flowers about 5 mm long, tipped orange or yellow, in July–September. It needs cool-intermediate, constantly humid and airy conditions, like a mossy branch in tableland cloud forest.

Where it grows wild

An epiphyte on the mossy parts of rainforest trees in positions with good air movement. Its range lies between the Big Tableland near Cooktown and the Tully River, and is centred on the Atherton Tableland; the type locality, Gadgarra, is near Lake Eacham. It hangs from trunks and branches in dappled light, among moss that holds moisture from mist and cloud.

Wild records give a median of about 1,000 m, which matches the upland rainforest of the Atherton and Evelyn tablelands. The recorded maximum of 3,500 m is impossible here, since no Queensland peak exceeds about 1,620 m.
