Banana Varieties. Historically, four sections have been recognized in Musa, AUSTRALIMUS , CALLIMUSA , MUSA (formerly known as EUMUSA), and RHODOCHLAMYS. Recent molecular analyses indicate a reduction to two sections, but much further study is required before the above system is abandoned. There are many banana cultivars. Parents of the cultivated types are Musa acuminata and Musa balbisiana, two wild species which are usually seedy. M. acuminata evolved primarily in tropical rainforests in Southeast Asia, whereas M. balbisiana originated in monsoon areas in northern Southeast Asia, and southern Asia.
