You're welcome, kuhleenuh.
A google for Polyscias tricochleata does bring up more but with no information. It is regarded as a synonym of Polyscias scutellaria but there are obvious differences, it seems taxonomy hasn't quite caught up with this one.
However, Tropicos gives it as Polyscias scutellaria cv tricochleata so it seems it's being treated as a cultivar.

A cultivar[nb 1] is a plant or grouping of plants selected for desirable characteristics that can be maintained by propagation. Most cultivars have arisen in cultivation but a few are special selections from the wild.

Typically, a cultivar would be treated as a named cultivated variety with a capital as in a name. As it was stated it is "common in American Samoa" and given the location of the island, my thoughts are it is a naturally occurring variety. Taxonomists have a huge job on sorting out names of plants from past mistakes.
There is a photo of one like yours under P. scutellaria, P. tricochleata is also listed on the Flora of North America ..
