Rhaphidophora stenophylla

A New Guinea Rhaphidophora described by Krause in 1912; the name means narrow-leaved. Collections come from hill forest at roughly 450–940 m in Papua New Guinea, including monsoonal rainforest on the Sogeri Plateau. Little else is published, so the conditions below come from the genus and a single climate site.

Where it grows wild

Labels mention forest, a slope transect in the Hak Valley and monsoonal rainforest on the Sogeri Plateau. We assume a root climber of humid forest like other Rhaphidophora.

Labelled records at about 457, 500, 853 and 940 m.
