Erect, leafy, dichotomously branched, rather 

 slender, i-2# high. Leaves 2-3-pinnate, the 

 lower slender-petioled, the upper nearly sessile; 

 petiole-bases dilated; ultimate segments linear, 

 acutish; umbels long-peduncled, 2 / ~3 / broad in 

 fruit, S-i2-rayed; rays #'-!#' long; pedicels 

 i // -4 // long; bractlets of the involucels 2-4, 

 linear, turned downward; fruit about l l " long, 

 somewhat longer than broad. 



In waste places, Nova Scotia to New Jersey, west 

 to Minnesota. Poisonous. Adventive from Europe. 

 Called also False or DOR'S Parsley, Dog-poison,

15. COELOPLEURUM Ledeb. Fl. Ross. 2: 361. 1844. 



Stout and tall maritime perennials, with large 2-3-ternate leaves, inflated petioles, and 

 compound umbels of greenish white flowers. Involucre of a few linear deciduous bracts, 

 or none. Involucels of numerous linear bracts. Calyx-teeth obsolete. Petals with an in- 

 flexed apex. Stylopodium depressed. Fruit oblong, scarcely flattened; dorsal and inter- 

 mediate ribs prominent, corky-thickened, the lateral ones slightly broader, acute but not 

 winged; oil-tubes solitary in the intervals, 1-2 under each rib and 2-4 on the coinmissurul 

 side. Seed loose in the pericarp, its face flat or slightly concave. [Greek, hollow-ribbed.] 



Two species, one widely distributed in the northern hemisphere, the other on our northwestern 

 coast.

Stout, branching, 2-3 high, glabrous below, 

 the umbels and upper part of the stem puberu- 

 leut. Lower leaves large, 2-3-ternate, the seg- 

 ments thin, ovate, acute or acuminate, sharply 

 and irregularly dentate and incised, i%'-2%' 

 long; umbels 3 / -5 / broad, io-25-rayed; rays 

 l / -2 / long; pedicels slender, 3"-6" long; fruit 

 oblong or nearly globose, 2# // -3#" long, the 

 lateral ribs scarcely stronger than the others. 



Sea-coast, Greenland to Massachusetts, on the 

 lower St. Lawrence river and the Pacific coast. 

 Also on the coasts of eastern Asia. Summer. 



16. LILAEOPSIS Greene, Pittonia, 2: 192. 1891. 



[CRANT/.IA Nutt. Gen. i : 177. 1818. Not Scop. 1777.] 



Small creeping glabrous perennial marsh herbs, the leaves reduced to linear terete sep- 

 tate hollow petioles, with simple umbels of white flowers. Bracts of the involucre several, 

 small. Calyx-teeth acute. Petals concave, acute, incurved at the apex. Stylopodium conic. 

 Fruit glabrous, globular, somewhat flattened laterally. Carpels nearly terete, the dorsal and 

 intermediate ribs filiform, the lateral ones much larger and corky-thickened, the commissural 

 faces each with a corky longitudinal projection; oil-tubes solitary in the intervals. Seed 

 terete. [Greek, resembling the genus Lilaea.'] 



A genus of wide geographic distribution, usually regarded as monotypic, but probably consist- 

 ing of several species.
