1. P. apiodora, Ciniy. Smooth, erect, 2 or 3 feet high, rather stout: heaves 

 mostly radical, 2 - iMeriiate, the cuneate-ovute leaflets laciniately pinnatilid and 

 toothed, ail inch lung: umbela long-pedimcled ; uiys G to 15, hiapidly puberiilent, 

 an inch or two long; involucre and invuhicels of 1 or 2 bracts, or wanting : liuwers 

 •white or pinkish : iVnit broadly ovate, 1^ lines long, the carpels 5-angled with 

 slightly prominent ribs : oil-tubes numerous (-t to 5 in the ilorsal intervals, G in the 

 lateral, and 8 or more in the commissure) : styles short : carpophore 2-parted. —

Sau Francisco and noithward ; Mendocino County {Bulunder) ; Oregon (Hull) ; Eastein Ne- 

 vada, IVatson. i*eifeetly mature I'ruit has nut yet been collected. The plant has a strong 

 pleasant odor, like that of Celery. 



11. BERULA, Koch. 

 Calyx-teeth minute. Stylopodium conical and styles short. Fruit nearly globose, 

 with a broad commissure, emarginate at base, tho ribs nerve-like, not raised above 

 the tiiick epicari) ; oil-tubes numerous ami contiguous, surrounding the terete seed. 

 Carpophore 2-parted, very slender. — A smooth [xuennial a(piatii! ; leaves jjinnate 

 and serrate ; involucres ami involucels of several lealleta ; liowors white. 



A single species (often luferrftd to the genus Slum) coniinon iu Europe, and widely though 

 sparingly distributed through the United States and Mexico. 



1. B. angustifolia, Koch. Erect but usually low, ^ to 3 feet high, the stem 

 stout and angled : leallets about G pairs, ovate-oblong to linear, ^ to 2 inches long, 

 often laciniately lobed at base, and the upper ones especially more or less deeply 

 cut-toothed : peduncles I or 2 inches long: rays an inch long or less; involucre and 

 involucels of G to 8 entire linear-lanceolate leaflets : fruit two thirds of a line long. 

 — Siuvi anguatifoHuia, Linn. 



Collected at Fort Tejon {Xantns, Rothrock) though without fruit, and reported from San Fran- 

 cisco ; Sierra Co., LcvDnon. The Ilelosciudiuvi (0 CaliJ'urnkum of Hook, k Arn. Hot. Bcechey, 

 H'2, lins been doulitfully referred to this apecie.s, but is described as jnocunibent, the lower leallets 

 jiinnatifid or pinnate, and the styles long. Benth. k Hook. (Gen. PI. i. 893) speak of the fruit 

 of the specimen in herb. Kew as having the epicarp thin over the intervals as in species of Sium. 

 The reference is therefore probably incorrect and the s])ecies remains uncertain. 



12. CICUTA, lann. Water Hemlock. 



Calyx-teeth small, acute. Stylo[)odium de[)ressed. Fruit broadly ovate or sub- 

 orbicular, slightly compressed laterally but the commissure narrow ; ribs broad and 

 obtuse, corky ; the oil-tubes solitary in the intervals. Seed subterete, Hat or 

 rounded on the face. Carpophore 2-parted. — Smooth tall branching marsh peren- 

 nials, with stout hollow stems ; leaves pinnate or pinnately decompound ; umbels 

 of white flowers many-rayed, the involucre small or none, and involucels of several 

 small bracts : routs thick and fascicled, very poisonous : flowering in sumnuir. 



A small genus of about half a do/en species, growing in dain|) or wet places, two of them very 

 widely distribute*! round the world in the northern hemispliere. The aromatic roots of the first 

 species have often proved fatal to those eating them, and the others are probably as dangerous. 



1. C. maculata, Linn, Stout, 3 to G feet high : lower leaves on ])etioles 1 or 

 2 feet long, bipinnate ; the leaflets (1 or 2 inclies, sometimes 4 inches, long) oblong- 

 lanceolate, acuminate, coarsely serrate with the veinlets running to the sinuses, 

 occasionally lobed, the lower petiolulate : rays an inch or two long, rather slender ; 

 involucre usually wanting; involucels of to 8 narrow lanceolate leaflets: fruit
