Comments |
Cheesman created Ensete calospermum as a new
combination (number 6 out of 25) in a brief note in his 1947 paper reviving the genus Ensete.
Cheesman revived one and created 24 new Ensete species in that paper but
acknowledged that field study might reveal synonymy. Simmonds 1960 reduced Ensete
calospermum on the basis of comparisons with collections of Ensete glaucum
from south-east Asia. See Musa calosperma for more comments. |
