Yunnan Wild Banana

Name: Yunnan wild banana (Musa itinerans)
Status: Native to China’s Yunnan province, this wild pink banana is vulnerable, according to the IUCN’s Red List.
Threats: Deforestation is the biggest threat to the species. The mountainous forest habitat of Musa itinerans, a wild relative of the domesticated banana, is being razed for commercial agriculture.
Impact: Asian elephants are losing a staple food source—and we may be too . As far as bananas go, we have put most of our energies into cultivating one variety for consumption, the Cavendish. Yet a fungus has run rampant in that species. Since t he Yunnan wild banana is a close relative to the bananas and plantains we consume, and it has proven to resist common banana diseases, it could be useful in breeding new varieties.
Interesting Side Note: Musa itinerans was the 24,200th species to be stored, a milestone for the seed bank . When the seeds were collected in 2009, it meant that the bank had met its initial goal of conserving 10 percent of the world’s species by 2010.
