4c-f), they are membranaceous with some faint veins, small, cucullate
("hooded") and possibly clawed, between 3.
Leaves congested, sub-opposite, cucullate
, sessile, broadly elliptic, to 7 mm long and 5 mm wide, entire to slightly bi- or trilobate, light green when young, later with the distal half purplish, lateral lobe(s) triangular, ascending, glabrous above, scarcely villous below, margins villous, especially along the distal half.
Gonostylus slender and cucullate
, 110-130 (126) um long, with numerous microtrichiae; crista dorsalis absent; megaseta 7-12 (9) um long.
Hyaline cortical cells of stems and branches with spiral fibrils (weakly fibrillose, sometimes without fibrils; branches always present; branch leaves with rounded or cucullate
apex; branch cortex without curved cells.
16-51 cm long, with 8-15 flowers opening more or less simultaneously; floral bracts cucullate
, triangular, semi-amplexicaul, 5 mm long, 2-2.
The striae along veins of abaxial leaf surfaces, the nearly simple stigma, and the petals slightly cucullate
and 8-nerved from the base in W.
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.
Dietrich and Deitz (1993) listed as synapomorphies for Cicadellidae: the mesonotum exposed posteriorly, the labium not reaching the metathoracic coxae, m-cul crossvein present, metatibia with distinct long setae, tarsomere I of hind leg without cucullate
setae, stemum IX and subgenital plate not fused, and abdominal tergum with divided acanthae; all of which are homoplastic characters in their analysis.
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).
8 mm wide, ovate, acuminate and incurved at the apex, slightly cucullate
, erect, yellowish-green, carinate near the apex, nerved, longer than the sepals, not concealing the rachis, glabrous.
5-3 m high, glabrous, with abundant milky latex; stipules widely ovate to triangular, cucullate
, 2-3 (-4) mm long, 2-3 (-4) mm wide.
20 mm long (with extended petals), sessile, densely arranged, odorless; sepals symmetrical or nearly so, ovate, 12-13 x 4-5 mm, free, entire, green, rigid, densely and coarsely white-floccose-lepidote except for the glabrous margins, apex acuminate-caudate, pungent, the adaxial ones carinate with keels decurrent on the ovary, the abaxial obtusely carinate; petals narrowly sublinear-spatulate, rounded and inconspicuously cucullate
