Section Distribution Common inland species from N. Johore to N. Perak [at least]. Description Trunk to 3 m tall, to about 15 cm thick, outer sheaths more or less suffused dull dark purplish. Leaves to about 250 cm long and 55 cm wide, glaucous but not white, powdery beneath, petiole and lower surface of midrib light green, petiole and base of midrib more or less mottled with dull light purple at least when old but never fully purple. Inflorescence horizontal near the base, apical part pendulous. Bracts deep crimson, more or less streaked (at least in the male stage) with yellow, each bract as long as the bud. Flowers in groups of 10 - 12. Female flowers not known. Male flowers : ovary pale, c. 10 mm long ; outer perianth member 3.8 cm long cream translucent with yellow lobes c. 5 mm long, tepal-lobes with subapical tip barely 1 mm long ; inner perianth member 19 - 20 mm long, 12 mm wide, back slightly humped, apex nearly truncate with tip 1 mm long, filament 20 mm long, anther 17 - 18 mm long ; style [and] stigma as long as anthers. Fruits with glabrous stalk, 10 - 15 mm long, fruit with beak 10 - 12 cm long, 2 cm diameter, distinctly but not strongly angled (convex faces between angles), beak 7 - 8 mm long and wide.
This is a common species from N. Johore to N. Perak, abundant where primary forest has been felled. Its leaves stand more erect than those of M. truncata, or M. malaccensis (I think) the habit being much more like that of M. violascens but the leaves are a little wider, and distinctly glaucous beneath.
It is probable that this has been confused with the lowland form of M. truncata (if such exists) or all lowland "truncata" may be this species.
