There seems to be a lot of confusion between these three (sometimes used alternatively for the same plant) as is evident from the following links:

I think Polyscias pinnata and Polyscias balfouriana are same as per

Keys are available at Notes on Polyscias (Araliaceae) from Micronesia – Micronesica

Any feedback is welcome.

Agreed this paper, 1989, considers both as synonyms of P. scutellaria (N. L. Burman) Fosberg (eFlora of China considers P. balfouriana as its synonym) but POWO, Catalogue of Life and WFO treat them as independent species. It would be interesting to know their differences.

All three are treated as distinct species by these databases.

Agreed Garg ji, but we have to follow established databases, and in this case all three agree.
