SCHIZEILEMA Domin, 1908

Fls 5-merous in simple to irregularly compound bracted umbels. Calyx-teeth 5, prominent, persistent; petals imbricate; disk thick, flat. Fr. ± tetragonous; mericarps subterete to dorsally somewhat compressed; ribs 5, evenly placed, lateral not close to commissure. Glab. perennial herbs with creeping and rooting stolons. Lvs simple to 3-5- foliolate. Some 15 spp., mainly of N.Z., with 1 in Falkland Is, 1 in Patagonia, and 1 in Victoria. The N.Z. and Australian spp. lack a district carpophore. The treatment follows in large part that of Domin in Engl. Bot. Jb. 40, 1908, 573-585.
