Basal leaves generally withered by the time of fruiting, bi- to subtripinnate with pinnatifid segments, deltoid and ± 3–15 × 2–12 cm. in outline, ultimate divisions ± 2–8 × 1–3 mm., ± furnished with upwardly directed, whitish strigulose hairs especially on the lower surface; sheaths ± 2–5 mm., pale-margined, indistinctly demarcated from the channelled ventral surface of the petiole; petiole ± 1.5–4.5 cm.; median leaves similar or the segments becoming narrower and more elongate, more shortly petiolate, sheaths long and narrow with involute margins; upper leaves similar but reduced, to trisect with elongate segments (the upper especially long and up to ± 50 × 5 mm., subentire to regularly acutely serrate), sessile on the narrow sheaths.
Morphology Reproductive morphology Inflorescences
Umbels very numerous to rather few, on slender, ± 1.5–13 cm. peduncles; rays 2–12, terete, appressed-strigulose, ± 7–30 mm.; involucre usually absent, rarely one narrowly linear bract present; partial umbels ± 2–18-flowered; pedicels very unequal, 0–4 mm., indumentum similar to that of the rays; involucel of ± 4–8 bracteoles 1.5–5 mm. long.
Morphology Reproductive morphology Flowers Calyx
Calyx-teeth very small to obsolete.
Morphology Reproductive morphology Flowers
Flowers white to pink or purple, the outermost petals of outer partial umbels not to decidedly radiant (to ± 2 mm.), the inner or all petals ± 0.75–1 mm., ± strigose-hairy dorsally.
Morphology Reproductive morphology Fruits
Fruit ellipsoid, ± 3–5 × 2–3 mm., both mericarps densely covered with long, tuberculate, glochidiate-tipped, white to purple spines along the obscure secondary ribs, or one with shorter spines or verrucae; stylopodia conical, short; styles short to slender, ± 0.25–1.25 mm., subequalling or much longer than the stylopodia.
