The Australimusa section is a group of Musa species that have given rise to the only group of edible-fruit bearing bananas not derived from Musa acuminata and Musa balbisiana.  The Fe'i bananas are highly distinctive with upright inflorescences and coloured (red or purple) plant sap. 

However, in one respect they are just like the edible Eumusa, their nomenclature is extremely confused.

According to Stover & Simmonds, Musa fehi was originally applied to a group of clones of cultivated plants grown for fruit in New Caledonia.  The clones probably originated by hybridisation of a range of species possibly including Musa maclayi, M. jackeyi, M. angustigemma, M. peekelii and possibly others as yet undescribed.  Stover & Simmonds give Polynesia & Melanesia as the source of the plants named Musa troglodytarum that Huxley, presumably erroneously, treats as synonymous with Musa fehi.

In contrast to Stover & Simmonds, Huxley states that Musa fehi was originally applied to plants from Tahiti and Musa troglodytarum to plants from Sumatra. 

Simmonds & Stover caution that the Fe'i bananas are so poorly understood that the use of Latin binomials is "unwise".
