Description
Very robust herb with watery sap, up to ± 2 m. tall; stem branched, grooved, up to ± 10 cm. diam. at base; stock very stout, taproot very deeply descending; offset plants arising from short stout rhizomes. Petioles (15)–20–30(40) cm. × (5)–10–20 mm., concave with stout median rib on ventral, convex on dorsal surface; sheath broad, tapering to petiole, with short broad rounded to toothed ligule, or ligule obsolete. Lamina about oblong to ovate-oblong in outline, 2-pinnate or sts ± 3-pinnate, (1)–2–4(6) dm. × (5)–15–20–(25) cm., coriac., light to rather dark green; veins evident on both surfaces. Primary pinnae, 5–10–(15) pairs, distant, broad ovate-oblong in outline, (5)–15–(20) × (3)–4–10 cm., with short slightly sheathing petiolule. Secondary pinnae 3–5 pairs, obliquely ovate-oblong, up to 5–(10) × 1–3 cm., sessile by very broad base, unequally 3–5 lobed; lobes about ovate-oblong, with cartilaginous margins produced into pungent points 2–3 mm. long. Stem-bracts with open concavo-convex sheaths up to 10 × 6 cm., narrowed to lamina up to c. 6 cm. long. Umbels compound, ± 4–8 cm. diam., us many ± aggregated into heads up to c. 2 dm. diam. Primary rays many, stout, unequal, up to ± 3 cm. long; involucral bracts linear, acute, pungent, 3–5 cm. × 5–10 mm. Secondary rays and bracts similar, shorter.
