Musa rosacea N. J. von Jacquin was an edible banana referable, according
to Cheesman, to M. balbisiana or, more likely, to M. sapientum.
Argent states that "a variant of M. x sapientum whose stem, leaves and fruit are tinged
with purplish blue is often sold as M. violacea J. G. Baker (an invalid
name). The name M. rosacea correctly applies to this hybrid but is commonly
and incorrectly applied to M. ornata." I do not know if it is
possible reliably to apply the name Musa rosacea to a living banana clone.
It is interesting to note that there is one banana clone sold as an ornamental in Europe,
'Purple Rain', that seems to bear some resemblance although I think this is more likely to
be a clone of 'Dwarf Cavendish'. |

According to Cheesman the origin of the confusion between M.
rosacea and M. ornata was a note appended by Nathaniel Wallich to the
original description of M. ornata in Flora Indica in which he states "this
is probably M. rosacea Jacq." It seems that Wallich made an honest
mistake but later authors blindly accepted the synonymy of M. ornata and M.
rosacea. Among these is the author of the Musa entry in RHS 1956 who gives a
nice description of M. ornata under the name M. rosacea. Iteration of Wallich's
mistake in horticultural texts led gradually to the name M. rosacea being
de-graded simply to an alternative name to M. ornata. In that sense the
name used in horticultural circles came to mean something quite different to von Jacquin's
original intention. This de-graded form of the name is referred to as M. rosacea Hort. non Jacq. in Huxley 1992 and Griffiths 1994.
As evidence of further confusion Shanmugavellu et al 1992 mention that one plant used as a
pollen donor in a banana breeding programme in India was labelled originally as M. rosacea (probably M. rosacea Hort. non Jacq.) but later identified as M. laterita. This
seems to simple case of mistaken identity, M. laterita is a good species. |
