Annual herb 4-17 dm. tall; leaves oblong to obovate, the blade 13-35 cm. long, 11-20 cm. broad, pinnately decompound, the ultimate divisions filiform, 4-20 mm. long, the petiole 5-6 cm. long; upper cauline leaves greatly reduced; peduncles 7-16 cm. long; rays 10-45, spreading, 3-10 cm. long, the pedicels 20- 50, 6-10 mm. long; fruit ovoid, about 4 mm. long, 2 mm. broad.
"To 15 dm, branched above, glabrous and ± glaucous throughout; lvs ovate in outline, the lower long-petioled, the upper less so and smaller; ultimate lf-segments 5–20 mm; umbels to 15 cm wide; rays mostly 30–40, spreading, subequal; fr 3–5 mm, half as wide; 2n=22. Native of s. Europe, escaped from cult. throughout most of the U.S. and elsewhere. July, Aug."
Fruit elliptic-oblong, strongly dorsally compressed, ± 3–5 × 2–3 mm., the ribs pale, the marginals wider and thicker; stylopodia shortly conical with crenulate margins; styles short, strongly deflexed on and shorter than the stylopodia.
Lower leaves 3–4-pinnate with 3–7 pairs of pinnae dissected into capillary segments 2–25 × 0.25–0.5 mm., each terminating in a sharp, pale or brownish mucro; largest leaves up to ± 20 cm. long, deltoid; petiole ± 0.5–2 cm.; sheaths triangular to narrowly oblong, finely striate, 1–7 cm., rather broadly membranous-margined, auriculate at the top with blunt to acute membranous auricles; upper leaves rapidly reducing, sessile on the sheaths, often with longer segments, the uppermost rarely reduced to sheaths alone.
Stem sparingly to considerably branched, wiry, terete, finely striate.
Umbels numerous, on mostly (1.8–)5–22 cm. peduncles, usually at least some lateral umbels partially ♂; rays 5–40, glabrous, 2–10 cm.; partial umbels 5–30-flowered, on glabrous, 2–8 mm. pedicels.
Erect, glabrous, annual herb ± 0.2–1 m. tall, with a pleasant aromatic odour recalling parsley; rootstock slender.
Robust, rather glabrous annual herb up to 75 cm., with a strong characteristic odour.
Leaves 3–4-pinnate, ultimate segments narrowly linear to filiform.
Stem terete, with numerous fine grooves.
Umbels terminal, equalled or exceeded by long peduncled laterals. Rays numerous, up to 4 cm. long; bracts and bracteoles 0. Partial umbels with up to 35 flowers, but those of small plants may have as few as 6.
Vittae well developed, 1 per interval and 2 in the commissural face.
Sepals obsolete; petals yellow with an obvious inturned apex.
Fruit elliptic, strongly dorsiventrally compressed, with a moderately well-developed marginal wing paler in colour than the body of the fruit. Stylopodium lowconical; styles short, clubbed at the apex, divergent and shed before the fruit matures. Dorsal ribs filiform, carpophore 2-cleft to the base.
