Biennial herb c. 1 m tall, with a narrow fleshy taproot. Stems terete and finely grooved. Petioles 5–15 cm long, with moderately well-developed sheathing bases. Stem leaves reduced and confined to bases with minute linear appendages on the inflorescence. Basal leaves ternate to partially 2-ternate, rarely with simple shortly trullate lamina and regularly dentate margins. Lobes of ternate leaves 2–6 cm long, linear to irregularly elliptic or oblanceolate; apices obtuse, bases narrowly cuneate, margins ± regularly serrate to irregularly dentate with remote teeth. Inflorescence much branched, with terminal and lateral umbels. Primary umbels with 4–6 ± regular rays 1.5–4 cm long; bracts and bracteoles 0. Partial umbels with 5–12 flowers on pedicels 3–5 mm long. Petals white to pale yellow-cream, with distinctly inturned apex. Fruit probably 2 × 1.5 mm when mature, ovoid, densely covered with obtuse vesicular hairs which obscure the ribs and other features of the fruit. |
