BoyceHerbs, medium sized to robust, latex-bearing, usually evergreen, sometimes seasonally dormant. Stem epigeal, erect or creeping,stout, covered with fibrous remains of leaves and cataphylls. Leaves solitary or few to several together; petiole sheath very short; leafblade peltate, ovate or ovate-oblong, base often emarginate, apex acuminate; basal veins short, well developed, primary lateral veinspinnate, forming a submarginal collective vein very near margin, marginal vein also present, secondary and tertiary laterals arisingfrom primaries at a wide angle, then arching toward leaf margin and forming a ± conspicuous interprimary collective vein, higherorder venation reticulate. Inflorescence solitary; peduncle shorter than petioles. Spathe barely convolute at base, ± fully expanded atanthesis, yellow, yellow and red or ± dark purple within, ovate or ovate-lanceolate, not constricted, apex acuminate; basal part persistentto fruiting stage; apical part becoming reflexed and revolute, marcescent. Spadix much shorter than spathe, densely flowered;female zone cylindric, often longer than male zone, mostly adnate to spathe; male zone contiguous with female zone, cylindric,ellipsoid, or subglobose, fertile to apex, obtuse. Flowers unisexual, naked. Gynoecium surrounded by whorl of 2–5 short, claviformstaminodes, more rarely staminodes absent; ovary subglobose to ovoid, 1-loculed; ovules numerous, hemiorthotropous; funicledistinct; placentae 2–5, parietal, in basal part only or extending from base to apex, defined stylar region ± lacking; stigma strongly 2–
