Musa itinerans is a wild species of bananas first described by Ernest E. Cheesman from plants grown at the Imperial College of Tropical Agriculture's field collection in Trinidad1 . The seeds had been collected in an "evergreen forest at Tagwin, Myitkyina, Upper Burma" (Myanmar). Its name refers to its "travelling" habit, as a sucker can emerge two meters away or more from the mother plant.
The diagnostic character for this species is its long rhizome. Cheesman describes the pseudostem as 4 m or more in height and 20-25 cm in diameter at the base. The inflorescence is semi-pendulous and the peduncle is velvety. The inside of the bracts is yellow. The individual fruits are about 10 cm in length and 3 cm in diameter and relatively spread out on the bunch. They are not very curved1 .
The genome of an individual collected on Hainan Island, China, was sequenced in 20166 . The assembled genome size is 462.1 Mb, covering 75.2% of the 615.2Mb genome and containing 32,456 predicted protein-coding genes. The sequence is available from the Banana Genome Hub7 .
The chloroplast genome was also sequenced8 . The DNA came from leaves collected in China's Yunnan province. The complete chloroplast genome was found to be 168,985 bp long, to contain 113 unique genes, including 79 protein-coding genes, 30 transfer RNA genes, and four ribosomal RNA genes.
