Morphology General Habit

Annual herb climbing or trailing to 2.5 m.; stem densely long spreading-hairy.

Morphology Leaves

Leaf-blade broadly ovate-cordate in outline, subscabrid-hairy especially on nerves with short straight hairs, sinuate-toothed, 40–95 mm. long, 52–90 mm. broad, deeply palmately 5-lobed, lobes somewhat elliptic or rhombic in outline, narrowed below, often (especially the central and largest) 3-lobulate, less often the lobes ovate or rounded-triangular, broadest at the base; petiole 42–120 mm. long, ± spreading-hairy.

sex Male

Male flowers solitary or 3–10 in sessile or up to 26 mm. pedunculate cymose groups; pedicels 4–30 mm. long; receptacle-tube 3–3.5 mm. long; lobes subulate, 1.5–2 mm. long; petals 5–6 mm. long, 2.5–4 mm. broad, yellow.

Morphology Reproductive morphology Flowers

Female flowers on 13–95 mm. long stalks; ovary ellipsoid, ± 8 mm. long and 5 mm. across, rather densely bristly, each bristle elevated on a slight papilla; receptacle-tube ± 3.5 mm. long and 2.5 mm. across; perianth as in ♂. Male flowers solitary or 3–10 in sessile or up to 26 mm. pedunculate cymose groups; pedicels 4–30 mm. long; receptacle-tube 3–3.5 mm. long; lobes subulate, 1.5–2 mm. long; petals 5–6 mm. long, 2.5–4 mm. broad, yellow.

sex Female

Morphology Reproductive morphology Fruits

Fruit (fig. 15/8, p. 95) on a 33–135 mm. long stalk, which is often expanded upwards, shortly ellipsoid or subglobose, 30–43 mm. long, 22–34 mm. across, softly aculeate (the aculei terete, often more abundant and longest at the stalk end of the fruit and practically absent from the distal end), grey-green with about 10 longitudinal bands of deeper green and of varying distinctness, sometimes concolorous, ripening pale lemon-yellow.
