 membranaceus, in alabastro globosus, per anthesin valvatiin 3-5-partitus. Stamina 

 numerosa (interdum usque ad 1000), filamentis repetito-ramosissimis conferta ; autherarum 

 IiKuli distinct!, subglobosi, divaricati, separatim filamento affixi, longitudinaliter dehiscentes. 

 Ovarii rudimentum 0. Fl. $ : Calyx (saepius an semper ?) spathaceo-fissus, caducissimus. 

 Ovarium 3-loculare ; styli breves v. longiusculi, 2-fidi v. rarius indivisi, patentes, plus

 Semina ovoidea, testa Crustacea; albumen carnosum j cotyledones plana}, latue. — Herba 

 elata annua, v. in regionibus calidioribus frutex arborescens, glabra, ssepe glauca. Folia 

 altema, ampla, peltata, palmatim 7-oo-loba, lobis serratis. Racemi ad apices ramorum
