Alocasia devansayana

A New Guinea Alocasia, first grown in European hothouses in the 1880s and transferred to Alocasia by Engler in 1912. There are no wild GBIF records, so conditions come from a representative lowland New Guinea climate and from how the genus grows there: warm, very wet and aseasonal.

Where it grows wild

No field notes were reachable. Like most New Guinea Alocasia it is presumably a terrestrial herb of shaded, wet lowland rainforest floor.

No recorded elevations. The climate point used is at 171 m, which is an assumption, not a record.
