Popoulu bananas are indigenous to the Pacific region. They were originally classified in their own subgroup (often designated as Maia Popoulu, Maia being the Hawaiian term for bananas), but are increasingly classified together with Maoli bananas in the Maoli-Popoulu subgroup.
The fruits are plump square-ended and noticeably thick in diameter. Most fruits are 2-3 times as long as they are wide1 .
Popoulu bananas are distinguished from Maoli bananas by having shorter and fatter fruits.
