Ligusticum.] divided into narrow-linear flat acute segments ½–1½ in. long and varying in width from filiform to ⅓ in., the broadest sometimes toothed or lobed at the tip.

11. L. carnosulum, ''Hook. f. Handb. N.Z. Fl.'' 96.—Small, 3–6 in. high, thick and fleshy, glaucous-green. Root stout, often as thick as the little finger, tortuous among shingle. Stems usually short, tapering downwards. Leaves 1–3 near the top of the stem or from the root, very thick and fleshy; petiole ½–2 in. long, with a short broad sheath; blade 1–3 in. diam., 2–3-ternately multifid, ultimate segments ¼–⅔ in. long, $1⁄15$–$1⁄10$ in. broad, very narrow linear, acute or subacute, curved, obscurely jointed on the rhachis. Umbel solitary, compound, large for the size of the plant. 1½–4 in. diam.; involucral bracts about 5, 2–3-ternately divided like the leaves, overtopping the umbel; rays numerous, rigid, almost woody in fruit, ½–1 in. long. Secondary umbels small, concealed among the bracts of the involucels, which far exceed the small white or pink almost sessile flowers. Calyx-teeth acute, prominent. Styles rigid, subulate.
