Spathe connate into a tube below, or nearly to the top, at length 

 entirely deciduous. Spadix free, monoecious, 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 angulai- from mutual pressure, 

 the uppermost often imperfectly hermaphrodite. Perianth gamo- 

 phyllous, cupular or suburceolate, truncate, often with a thickened 

 margin. Staminodes none. Ovary supeiior or inferior, often very 

 oblique, 1-celled with basal placentation or 2 parietal placentas, or 2-4- 

 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, anatropcus, surrounded by mucilage. Male flowers 

 numerous, in a cylindric spike, crowded or lax. Perianth as in the 

 female flowei*s, but less deep, and not contracted at the mouth, or 

 rarely Ji-5-lobed, often laterally compressed. Stamens o-4, rarely 

 fewer, free, inserted at the base of a rudimentary ovary, exserted ; 

 filaments filiform or clavate ; anthers basifixed, with oblong or elliptic 

 pasrallel 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 Arum. Khizome 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 wliich are extra tropical.
