 Calyx-teeth obsolete. Fruit broadly ovate, laterally compressed, the carpels with 

 5 prominent obtuse equal ribs; oil-tubes none. Seed terete, with a deep narrow 

 groove on the inner lace. Carpophore 2-parted. — Tall smooth biennials ; leaves

1. C. maculatum, Linn. iSttni 2 to 5 I'eet high, from a white fusiform root, 

 branching, often spotted with purple : leaves bright green, the segments half an 

 inch long, pinnatilid, with acute lobes: umbels 12-20-rayed, the rays 1 to 1^ 

 inches long : petals obtuse or with a very short indexed \nm\i : fruit H lines long, 

 shorter than the pedicels. 



Sparingly introduced in waste places in the neigliborlioocl of the older towns. The bruised 

 leaves exhale a sickly disagreeable odor. The extract of the ]ilant has pow.rfid narcotic and 

 alterative jiroperties, and is a valuable remedial agent in the hands of eonii)eteiit jihysicians. The 

 root ignoranlly eaten by childicn and others has not larely proved fatal in its etlects. 



7. APIUM, Linn. Cici.euy. 

 Calyx-teeth obsolete. Stylopodium depressed. Fruit broadly ovate, laterally 

 compressed, the carpels nearly straight, somewhat ribbed obtusely ; oil-tubes solitary 

 in the intervals. Seed nearly terete, not channelled nor concave on the face. Carpo- 

 phore entire. — Smooth ; leaves decompound ; umbels terminal, often nearly sessile 

 opposite the leaves ; flowers white ; involucre and involucels small or none. 



Including about u dozen species, as limited by Beutham k Hooker, Rome widely distributed, but 

 half of them confuied to the Southern United States east of the Kocky Mountains. The only 

 species found in California is a native of the coasts of Europe, widely naturalized, under cultiva- 

 tion much changed and ini])roved, becoming the garden Celery. The cultivated Parsley is another 

 member of the genus {A. I'ctroscUnuin). 



1. A. graveolens, Linn. liiennial, witli a fibnms root, erect, branching and 

 rather leafy, a foot <ir two liigh: leaves pinnate with 1 or 2 pairs of broadly cuneate- 

 ohovato or rliond>oiilal lealhits, 3-5-lol>ed and si)aringly toothed, an inch or two 

 long, the ui»i)er ternate with nearly entire oblanceolatu leallets : umbels sessile cu- 

 very shortly pedunculate, naked ; rays G to 12 or fewer, slender, an inch huig or 

 less : fruit two thirds of a line long. 



Rare in California, but has been collected in salt marshes from Santa Barbara to San Diego, and 

 also at Fort Tejon.

 styles short. Fruit cordate in outline, laterally compressed with a narrow commis-

 cave and somewhat incurved longitudinally. Carpophore 2-parteil, rigid. — A 

 smooth slender branching Califoriuan annual ; leaves dissected, with linear seg- 

 ments ; umbels sessile, naked, fewrayed, in the forks or ojjposite to the leaves ;
