Characteristics

Stems longitudinally sulcate, shortly hispid when young, glabrescent, up to 2 m long. Leaves herbaceous, broadly triangular-cordate or suborbicular-cordate to broadly cordate or pentagonal, usually with a wide and shallow basal sinus, more or less thinly and shortly hispid-setose, 4-9 cm long and 5-9 cm wide, palmatilobed with usually 5, rarely 3 lobes, usually incised to about the middle with broad ovate or obovate to obcuneate lobes, occasionally (in the form described as T. rotundata Burtt Davy) more deeply so with oblong or lanceolate lobes, rarely nearly undivided, 5-angled; lobes usually obtuse or rounded, often distinctly mucronate to apiculate, distinctly dentate to coarsely pinnatilobed; petioles rather firm, shortly hairy, 2-3.5 cm long, almost invariably with a large suborbicular-cordate, long dentate-ciliate stipuliform bract up to 2.5 x 2.5 cm at the base. Male flowers: pedicels solitary or fascicled or occasionally racemose on a very short common peduncle, filiform, hairy, 1-2(-4) cm long; receptacle subcylindric, usually distinctly rounded to subtruncate at the base, slightly widening upwards, 10-16 mm long and about 3 mm in diam., sepals reflexed, triangular-subulate, distant, about 2 mm long; petals patent to somewhat reflexed, triangular-oblong or triangular-lanceolate, acute and usually recurved at the apex, 6-10(-15) mm long, 2-3 mm wide at the base. Female flowers: peduncle slender, up to 2 cm long, incrassate in fruit; ovary broadly ovoid to subglobose, rostrate, glabrous or puberulous; perianth as in the male but receptacle and petals slightly wider. Fruit broadly ellipsoid or ovoid, 2-3 cm long and in diam., red when ripe. Seeds 10-12 x 5 x 3 mm.
