Comments Published as Musa mirabilis the "x" is added to indicate its presumed hybridity.

This is one of several Indonesian banana cultivars given a spurious species name by Takenosin Nakai. Nakai says of it in his idiosyncratic English; "The stem of this greenish banana attains to 4 - 6 meters high, being very ordinary form of banana, but not pruinose at all. The basal 2 - 7 bracts have female flowers and others hermaphrodite flowers. The flowers are halfway persistent, so the small imperfect fruits from the hermaphrodite flowers make long tail crowned by shrinked and dried perianth at the end of spike, which gives a peculiar feature to this banana. The small imperfect fruits count more than 1000. The real fruits from female flowers taste rather nice".

This description of M. mirabilis seems very like Musa chiliocarpa C. A. B. Backer more properly known as Musa (AAB group) 'Pisang seribu' except that Nakai distinguishes them as follows:

Flores afeminei steriles in nodis basalibus 4 - 5 biseriales in fructu virides angulati duri inedules. Flores ceteri omnes hermaphroditi, fructus edules expermos 1000-3100 in una spica densissime collocatos fromant. Folia subtus pruinosa. Spica fructifera vulgo 2 - 3 metralis.

= Musa chiliocarpa

Flores basales faeminei fertiles fructus veros formantes
Axis inflorescentiae velutina
Folia subtus et petioli non pruinosa
Pseudocaulis [sera]mineus. Bractae basales 2-7 cum floribus faemineis
qui demum fructus veros formantibus, ceterae cum floribus
hermaphroditis qui demum fructus parvos inedules formantibus

= Musa mirabilis
