Spathe connate into a tube below, or nearly to the top, at length 
entirely deciduous. Spadix free, monecious, usually with a naked 
Space between the male and female parts, or the base of the male spike 
more or less interrupted, without neuter organs or appendix. Female 
flowers in a single cycle or in 2—5 (or more ¢) series or spirals, crowded, 
free or connate, laterally compressed or angular from mutual pressure, 
the uppermost often imperfectly hermaphrodite. Perianth gamo- 
phyllous, cupular or suburceolate, truncate, often with a thickened 
margin. Staminodes none. Ovary superior or inferior, often very 
oblique, 1-celled with basal placentation or 2 parietal placentas, or Car 
celled in the lower part with axile placentation ; style exserted; stigma 
discoid-capitate, or oblique and ovate or lanceolate. Ovules 2 to several 
in each cell, anatropous, surrounded by mucilage. Male flowers 
humerous, in a cylindric spike, crowded or lax. Perianth as in the 
female flowers, but less deep, and not contracted at the mouth, or 
rarely 3-5-lobed, often laterally compressed. Stamens 3-4, rarely 
fewer, free, inserted at the base of a rudimentary ovary, exserted ‘ 
filaments filiform or clavate ; anthers basifixed, with oblong or elliptic 
parallel or divergent cells, opening by longitudinal slits. Fruit not 
seen, described as a berry containing 2 to several ovoid slightly com- 
pressed seeds, with a thin black striated testa, copious fleshy albumen, 
and an elongated fleshy axile embryo.—Perennial herbs with the habit 
of an Arwm. Rhizome usually stout, fleshy, nodose or ringed. Leaves 
all radical, petiolate, cordate, hastate, sagittate, or rarely entire at the 
base, contemporary with the flowers or appearing after them. Peduncle 
terminal or axillary, solitary, or rarely 2 from one axil. 
An African genus of about 15 species, two of which are extratropical.
