Characteristics

Glab. succulent sparingly branched herb, up to ± 6 dm. long, creeping and rooting at nodes; stems long, fistulose, often floating in water; stock rather short, roots slender. Petioles of radical lvs 15-50 cm. long, narrowed to lamina and membr. sheath. Lamina ± reniform in outline 3-9 cm. diam.; 3-5-flabellately divided to or near base into broad-or narrow-obcuneate divisions; these again ± deeply cut or toothed. Cauline lvs 2-4, smaller. Peduncles simple or branched, lf-opposed, up to 15 cm. long; bracts narrow-lanceolate, up to 2 cm. long. Fls 1-2 cm. diam.; sepals 5, oblong, ± 4 mm. long; petals (3)-5-(7), narrow-oblong, us. ± 7 mm. long but sts much shorter, yellow; gland 1 basal. Fruiting heads globose to ovoid, 6-7 mm. long; achenes 1·5-2-(3) mm. long, obliquely ovoid, ± compressed to ± turgid, keeled; style ± 2 mm. long, slender, flattened and widened at base.

More

Basal lvs on stout erect petioles (7)-15-30-(40) cm long, arising from somewhat bulbous nodes; lamina ternate, glabrous, (1.5)-2-4 cm wide; leaflets sessile or shortly stalked, cuneiform, shallowly 3-fid, crenate or bluntly dentate at tips; lateral leaflets longer than terminal; cauline lvs few, similar to basal but smaller. Fls (1)-3-5 per stem, 10-15 mm diam.; pedicels glabrous. Sepals spreading or weakly recurved, glabrous. Petals 5-7, yellow, narrowly oblong, shortly clawed; nectary single, 1-1.5 mm from petal base, with a short semilunar scale. Receptacle with a basal collar of bristles.
