Pterophylla samoensis, formerly known as Weinmannia samoensis, is a species of plant in the family Cunoniaceae.

[1] 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.

[2] 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.
