Bulbophyllum caldericola

Bulbophyllum caldericola is a small creeping epiphyte from the rainforests of the Tweed caldera and Border Ranges on the New South Wales–Queensland border. Tiny pseudobulbs spaced along hanging rhizomes each carry one fleshy leaf, and in October and November it bears single white flowers with yellow-tipped sepals and an orange lip. It is a cool to intermediate grower from warm-temperate rainforest above 700 m.

Where it grows wild

It grows on the trunks and larger branches of rainforest trees, occasionally on rocks, in warm-temperate rainforest above 700 m. Its rhizomes mostly hang free, attached only at the base. NSW PlantNET treats it as a synonym of Bulbophyllum lamingtonense, the cream rope orchid.

It grows above 700 m, on the rim and slopes of the Tweed volcano caldera and the Border Ranges and Lamington area. No elevations were measured.
