Calyx-teeth small, scarious,, subulate. Stylcpodium short, conical. Fruit linear- 

 oblong, laterally compressed, with a rather broad commissure, somewhat contracted 

 at the apex ; ribs narrow and filiform ; oil-tubes 1 or 2 in the intervals, 4 on the 

 commissure. Seed reniform in section, slightly channelled on the back under the 

 oil-tubes, broadly furrowed on the face, with a central longitudinal ridge. Car- 

 pophore 2-parted. — Smooth branching Californian perennials; leaves pinnately or 

 somewhat ternately decompound, with linear leaflets ; umbels long-peduncled, with 

 involucres and involucels of several lanceolate acuminate subscarious bracts; flowers 

 white, polygamous. 



LP. Californicum, Gray. Stem 3 or 4 feet high: segments of the leaves 

 linear, entire or toothed, the terminal one elongated, an inch or two lon-r • upper- 

 most leaves simple : umbels 9 - 12-rayed, the primary umbel fertile, witlfrays two 

 inches long ; the others sterile, with rays an inch long and very slender pedicels 

 exceeding tlie bracts : petals shortly acuminate : fruit 4 lines long, shorter than the 

 pedicels, l^ lines broad, with obtuse ribs : oil-tubes and seeds as described in the 

 generic character. — Proc. Am. Acad. vii. 34G. ChcerophyUum (?) Californicmi

Collected only by Bigcloiv at Knight's Ferry ; May. 



2. P. Bolanderi, Gray. Two feet high : leaflets pinnate, the segments more 

 narrowly_ linear : umbels many-rayed ; rays 5 to 9 lines long ; the conspicuous 

 scarious involucels exceeding the pedicels : petals very long-acuminate, with the 

 midvem strongly impressed : fruit 1|- Hues long, oblong, the narrow ribs becoming 

 elevated and undulate ; oil-tubes more numerous and obscure, 2 or 3 in the inter^ 

 vals : seed more compressed dorsally, and broader in proportion, not grooved on the 

 back, the facial sulcus broad and shallow and but slightly raised in the centre —

tl.p'^vi"'"^^.'' v'li ^'^f^'i^?,*;^^'^T"S from any of tlie preceding genera, has been collected in 

 the Yosemite \al ey by both Dl^ Torrey and Dr. Gray, with the fruit however too immature for 

 Its satisfactoiy determination. The truit as found is narrowly oblong, 4 lines long, laterally com- 

 pressed with a rather wide commissure, slightly ribbed on the back ; disk evident, but stylopodium 

 depressed ; oil-tubes obscure, probably solitary in the intervals ; seed subterete, with a deep tri- 

 angular facial sulcus ; carpophore 2-parted. The plant is a foot high or less, glabrous, slender, 

 shortly caulescent ; leaves ternate or bipinnate, with linear acute segments, 1 to 3 lines Ion" • 

 umbels lew-rayed, the rays very unequal, an inch long or less ; involucre none ; involucels of"l 

 or 2 small braetlets ; flowers yellow, the calyx-teeth obsolete. 



17. CENANTHE, Linn. 

 Calyx-teeth rather prominent, acute. Stylopodium short-conical, the styles at 

 length elongated. Fruit oblong to globose, not compressed, with a broad commis- 

 sure, the ribs rounded and corky, with very narrow intervals ; oil-tubes solitary. 

 Seed somewhat compressed dorsally, flat on the face. Carpophore none. — Gla- 

 brous herbs, mostly aquatic ; leaves pinnate or decompound ; umbels usually in- 

 volucrate ; flowers white. 



The following are our only representatives of this genus, of which there are 20 or more species 

 in the temperate regions of the Old World.
