cirri well-developed, with acanthophylls, without spines abaxially, with intermediate acanthophylls present
(i.e., distalmost pair of pinnae reflexed as acanthophylls and with swollen bases and/or proximalmost
acanthophylls like vestigial pinnae), without a wide gap between pinnae and acanthophylls. Inflorescences
with the rachis ridged, not twisted, much thicker than the numerous, closely spaced and spirally or irregularly
arranged rachillae, each rachilla not or only briefly adnate to the rachis, subtended by an acute bracteole and
with a well-developed axillary pulvinus; peduncles 8.8(7.8–10.6) mm wide; peduncular bracts 48.5 cm long,
broad, the surfaces ribbed, brown tomentose, densely covered with long, straight or sinuous, briefly swollenbased,
diagonally or vertically oriented spines, these flattened or triangular in cross-section, whitish-brown
proximally, black or brown distally, with tomentose margins; rachillae 21(20–22), glabrous or scarcely
tomentose initially; proximal rachillae 18.5(17.5–19.5) cm long, 2.5(2.1–2.9) mm wide; stamens 12; fruits
25.1(23.9–27.4) mm long, 21.7(20.1–24.1) mm wide, the surfaces bumpy from numerous, subepidermal,
short, oblique fibers; fruiting corollas less than one quarter as long as fruits, splitting irregularly into 3 lobes,
the lobes often splitting again; endocarps obovoid with rounded apices, the pores lateral.
Distribution and habitat:—From 9°17’–9°21’N and 78°55’–79°47’W in central Panama at 270(150–
425) m elevation in lowland rainforest (Fig. 7).
Taxonomic notes:—Desmoncus kunarius is characterized by its large size and unusually large fruits.
