Where it grows wild

Herbarium labels describe rainforest along a stream on Mt Otto and a cliff in mossy submontane rainforest on Mt Michael, both around Lufa and the Asaro valley.

It has been recorded from 900 to 2,600 m, with a median of 2,500 m. Most collections are from 1,950 to 2,600 m. The single 900 m record is probably a mislabelled elevation, since the same collection is also labelled 1,800–2,200 m.
