Bulbophyllum hirudiniferum

A rare epiphytic Bulbophyllum from Papua New Guinea, known from very few collections, including one on a Rhodamnia tree at about 900 m in Morobe. Little is published on its ecology, so care is built from the warm, humid hill-forest climate at its collection sites and from general practice for warm-growing New Guinea Bulbophyllum.

Where it grows wild

An epiphyte in lowland to hill forest in eastern Papua New Guinea; one specimen label records it on Rhodamnia, a small tree of forest and forest edges. Beyond that, its microhabitat is not well documented.

The two known specimens come from about 460 m (Koitaki, near Port Moresby) and 910 m (Bangalum, Mumeng, Morobe).
