Pterophylla samoensis

Pterophylla samoensis, formerly known as Weinmannia samoensis, is a species of plant in the family Cunoniaceae. It is a tree native to the Samoan Islands and to Rarotonga in the Cook Islands.

In the Samoan islands, Pterophylla samoensis is a common canopy tree in montane forests on lower mountain slopes, and in cloud forests above 650 metres elevation. It also grows on rocky upland lava flows.

It also grows in Rarotonga's Metrosideros cloud forest, on cloud-shrouded peaks and ridges above 400 metres elevation. Pterophylla samoensis is part of a low forest canopy which averages eight meters high, dominated by Metrosideros collina.
