Comments	The variety name of Musa textilis var. tashisor is misspelled at WCM, probably following the transliteration by Hseih et al in the Index for Scientific Names of the Flora of Taiwan which is at http://tai2.ntu.edu.tw/fot/V6/V6INDEXen.pdf. It should be var. tashiroi as indicated by Hayata. Although poorly known, Musa insularimontana is obviously very close to Musa textilis L. Née and is perhaps vulnerable to reduction.
