Bulbophyllum amplebracteatum
An epiphytic Bulbophyllum from the Moluccas, Sulawesi and the southern Philippines, split into three subspecies. It is known mostly from herbarium and botanic-garden material, with collections from lowland to mid-elevation forest. Grow it as a warm to intermediate, humid, shaded epiphyte; details of its ecology are poorly documented.
Where it grows wild
GBIF labels place it in primary forest (including disturbed 40 m tall forest on alluvial soil in the Sopu valley south of Palu), forest remnants on steep hillsides near Rantepao, and montane forest with roadside regrowth in Tana Toraja, Sulawesi, and on Halmahera and near Kanikeh (Seram) in the Moluccas. Several specimens were grown at Bogor Botanic Garden. Like most Bulbophyllum it is an epiphyte on trunks and branches.
No elevations are given on GBIF labels. The Sulawesi sites range from river valleys to the Tana Toraja highlands at roughly 800–1500 m, so it probably spans lowland to lower montane forest.
