 anthers small 2-dymo-g'lobose ; cells laterally or extrorsely rimose, 

 longitudinally adnate to thin connective. Germen (in male flower 0), 

 3-loeular subsessile; style branches 3, afterwards beyond middle 

 2-partite, within and on all sides much papillose stigmatiferous (red). 

 Ovrdes in cells solitary descendent ; micropyle extrorse superior ; 

 obturator thick subhemispherical. Gapsule 3-locular ; exocarp finally 

 solute, externally smooth or echinate ; cocci solute from axis. 

 Seeds smooth (more or less spotted) ; aril of exostome depressed, 

 conical, obscurely 2-lobed ; cotyledons of large embryo foliaceous, 

 subelliptical, equal in breadth to albumen — Arborescent or tall 

 herbaceous plants ; leaves alternate stipulate ; j^otiole long at ventral 

 line, bearing gianduliform tubercles ; limb wide, usually peltate, 

 palmatinerved, 7-15-lobed, unequally dentate; flowers in terminal,
