Comments	This is a Javanese form (the "Buitenzorg form") of M. acuminata and close to Musa acuminata subsp. malaccensis from Peninsula Malaysia and Sumatra. It is remarkable that such a well known subspecies should never have been formally published or if it has I do not know the author. Karamura (1998) lists this as nomen nudum. The taxon is treated by Nasution (1990) in his study of intraspecific taxa of Musa acuminata in Indonesia. I have not seen Nasution (1990) but from Pollefys et al 2004 I am unsure whether Nasution treats this as a subspecies or varietas. Pollefys et al state that Nasution (1991 [sic]) lists zebrina as a varietas (table 6, p. 15) but comment that it is usually referred to as a subspecies. In Appendix C. Pollefys et al list zebrina as a subspecies citing Nasution (1991[sic]). Valmayor et al 2002 (p.1 - 2) also list the plant as "Musa acuminata Colla subsp. zebrina (v. Houtte) Nasution". See comments at Musa acuminata. Like "sumatrana", "zebrina is used rather indiscriminately in horticulture as a species, variety or cultivar name for extremely attractive foliage plants with with leaves more or less striped adaxially with purple red and more or less suffused with purple red abaxially (pictures here or http://www.mobot.org/gardeninghelp/plantfinder/Plant.asp?Code=C539).
