8-flowered; floral bracts orbicular or nearly so, 20-27 x 25-27 mm, apex rounded, incurved and appearing cucullate
, greenish-yellow toward the apex and yellowish-green at the base, glabrous or nearly so, equaling 1/2 of the sepals length, strongly convex, carinate or the upper ones obtusely if at all carinate, covered by an oleaginous substance.
Precise pollen placement, protection of the pollen by the cucullate
staminode and possible adaptation to pollination by distinctive morphological changes are innovations that may explain the richness of Marantaceae compared to its sister group, the Cannaceae (Kennedy, 2000).

Pachyanthus monopleurus has some distinctive features such as the presence of peltate scales, absence of acrodromous venation and globose and cucullate
external calyx lobes.
