Spathe convolute below, constricted at the base of the limb ; tube per- 

 sistent in fruit ; limb deciduous. Spadix shorter than the spathe, free, 

 monoecious, 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, 

 w^ith 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.
