| Description |
"Pseudostems 4 - 5 m. tall, suckering ;
petioles 60 - 70 cm. long, grooved above, tightly clasping at the base ; leaf-blade
oblong, becoming narrower towards the apex, about 3 m. long and 40 cm. wide, rounded at
the tip, the two sides unequal at base ; inflorescence at first horizontal, about 8 basal
hands female, distal hands male, quite pendulous ; peduncles and rachis minutely pubescent
; male bud in advanced stage of anthesis obovoid, the bracts imbricate; the bract pale
yellowish crimson with dark colour at the apical and marginal parts, oblong, obtuse, 15
cm. long, 6 cm. wide, soon deciduous ; male flowers 9 - 10 per bract in two rows, the
compound tepal 4.5 - 5.0 cm. long, apex 3- or irregularly 5-toothed, the outer lobes about
1.5 mm. long, acute with dorsal filiform appendage of 2 mm. long ; the free tepal 4 cm.
long and 1 cm. wide, broadly linear, strongly curved, acute at the apex, cuneate at base,
the stamens 5, shorter than the free tepal, the sterile style 3.5 cm. long, with
ellipsoidal stigma that is 6 mm. long and 2.5 mm. wide ; fruit bunch horizontal, lax,
about 9 fruits on each hand ; individual fruit 11 - 12 cm. long (including pedicel of 2
cm. long), 2.0 - 2.5 cm. in diameter ; seeds numerous, depressed obpyriform, 4 - 5 mm.
across and 5 - 6 mm. high, with many tubercles".

"From the
characteristics of polished and imbricate male bud, and also from the general appearance
of plant, this new species seems to be closely related to M. textilis. On the
other hand, the male flowers and the seeds are alike to those of M. borneensis.
In the field, I, at first, referred this specimen to M. textilis, but on careful
examination, it proved that the flower is larger than that described by Cheesman (1949),
and that the tuberculate seed is also larger, measuring 4 - 5 mm. across and 5 - 6 mm.
high. Musa muluensis and M. cf. textilis (Hotta 13017) are the
bananas similar to M. tuberculata in the areas we surveyed, but they have short
free tepals with the apex rounded up or bittenly [sic]
truncated. According to Beccari's and Cheesman's description [of M. borneensis], M. tuberculata differs distinctly
from M. borneensis in the arrangement and the number of flowers; the former has
about 10 flowers biseriately arranged in a bract, the latter has fewer, usually 4
uniseriately arranged in a bract". (Hotta 1967). |
