This recently described species is quite distinct. Its pubescence and elongated
inflorescences give it a handsome appearance. The recency of this species, and the
subsequent species Manibot bandroana, in addition to the other new taxa described in
this monograph, are clear indications that more intensive investigations and collections in
South America will very likely uncover more new taxa in the genus. N. D. Cruz (1965)
has determined the chromosome count of this species as 2n = 36.

Shrubs. Young stems sparsely pubescent; mature stems glabrous. Leaves alternate;
stipules filiform, ca 1.25 cm long, pubescent, caducous; petioles ca 15.0 cm long,
pubescent, obtuse-angled, in cross section, petiole attachment to lamina basal, nonpeltate;
with 2 pubescent, 0.5 cm long lobules inserted at the petiole-lamina junction; wax pattern
of abaxial lamina surface smooth; venation camptodromous, veins on the abaxial lamina
surface pubescent; lamina palmately 5 lobed, occasionally 7; median lobes obovate-elliptic
8.0-12.0 cm long, 4.0 cm wide, margin entire, apex broadly acuminate, base angustate,
base of lobes 0.4 cm wide, width between base of sinus and petiole-lamina junction less
than 1.0 cm; lowest lobes similar to median lobes in outline, slightly smaller.
Inflorescence a monoecious, terminal, many branched panicle, ca 15.0 cm long;
bracteoles foliaceous, 1.0 cm long, 0.4 cm wide, pubescent; bractlets foliaceous. Pistillate
flowers restricted to the base of the upper half of the inflorescence; pedicels 1.5 cm long,
pubescent; tepal 1.5 cm long, cleft to base into 5 strap-shaped lobes with considerable
purple pigmentation, disc prominent, ovary glabrous, subglobose. Staminate buds more or
less conical, flowers large, tepal sometimes as long as 2.2 cm, dark purplish tinged,
pubescent, cleft 1/3 way down into 5 lobes, lobe apex tapering, stamens 10, in 2 whorls
of 5 each. Fruits and seeds non vidi. Capsule surface winged (fide original description).

This species and the preceding one, M. jolyana, are closely related elements. They are
distinguished one from the other in that M. bandroana possesses smaller leaves and is less
densely pubescent than M. jolyana. These two species are closely related to M. pohlii.
