Where it grows wild

Labels describe mixed lowland tropical rainforest on river terraces and steep slopes, a moist gully in oak forest, and one plant growing as a low epiphyte 4 m up a small tree on Mt Wawonseru, Sulawesi.

Records with altitudes fall between about 350 and 1,075 m. Some New Guinea localities (Mt Otto, Hunsteinspitze) are likely higher or lower.
