Leaves: Petioles 1–2.5 cm long; not aculeate; pubescence a single type on each petiole; antrorse-strigose, or retrorse-strigose (to weakly so); with nonbreakaway hairs. Leaf blades 5-palmately lobed; weakly with the margin serrate; ovate in outline to broadly ovate in outline; subcordate at the base; with a basal sinus; 0.2–0.6 cm deep; acute at the apex to broadly acute at the apex; 3.5–8.5(–11) cm long; 3–7 cm wide; 1.2–1.6 times longer than wide; antrorse-strigose on the upper surface, or scabrous on the upper surface; not aculeate on the veins below; antrorse-strigose on the veins below (to weakly so); scabrous on the intervenium below, or antrorse-strigose on the intervenium below; not ciliate on the margins; with nonbreakaway hairs. Central leaf-blade lobe symmetrical; entire, or pinnatifid; narrowly elliptic in outline to elliptic in outline; acute at the apex to broadly acute at the apex; 2.5–6.5(–7.5) cm long; 0.2–2.5(–3) cm wide. Lateral leaf-blade lobes assymmetrical; entire; elliptic in outline; acute at the apex to broadly acute at the apex; 0.5–2.5 cm long; 0.4–1.8 cm wide.

Female flowers: Pedicellate. Pedicel terete in outline; 8–13 mm long; antrorse-strigose, or retrorse-strigose; with nonbreakaway hairs; weakly flaring upwards from a narrower base to a wider apex. Hypanthium hour-glass shaped; not distinctly ridged. The lower 2/3s of hypanthium fused to the ovary. Fused portion of hypanthium ellipsoid; 7.2–8 mm long; 4–4.8 mm in diam; not tuberculate; aculeate; glabrous. Aculei stiff; 1–1.8 mm long. Hyaline bristle at apex of aculeus ca 0.5 mm long; 0.4–0.5 times as long as the opaque base. The upper 1/3 of hypanthium free from the ovary.
