Distribution Borneo. BRUNEI. Brunei Temburong: along Sungai Lacquan, a branch of Sungai Batu Apoi, in riverside open place, on rich and deep soil, standing mixed with M. flavida and M. campestris, Jan. 31, 1964, M. Hotta 13878.
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".

Comments "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".
