Spathe convolute below, constricted at the base of the limb ; tube per- 
sistent in fruit; limb deciduous. Spadix shorter than the spathe, free, 
moneecious, terminating in a naked appendage (which is sometimes obso- 
lete in cultivated plants) ; female part contiguous with the barren basal 
part of the male inflorescence. Perianth none. Female flowers numerous, 
with a few neuter organs (pistillodes) intermixed with them : ovaries 
free, 1-celled ; stigma sessile or subsessile, discoid or cushion-like ; ovules 
numerous, biseriately affixed along 3-5 parietal placentas, obliquely 
orthotropous, with long funicles. Male flowers with 3-5 anthers con- 
nate into a sessile angular truncate body; anther-cells opening by 
terminal pores. Berries enclosed in the tube of the spathe, which 
finally ruptures, obovoid, subtruncate, 1-celled, many-seeded. Seeds 
narrowly ovoid, small; testa thickened, ribbed; albumen copious; 
embryo axile at the apex of the albumen.—Herbs with a tuberous 
rootstock. Leaves all radical, with long petioles, peltate, ovate, cor- 
date or obtusely sagittate at the base, reticulately veined between the 
primary veins. Peduncles solitary or 2 or more from the same axil. 
A small genus of about 7 syecies, natives of Tropical Asia and the Malay Archi- 
pelago. The following has been introduced and become naturalised in some parts of 
Africa.
