Osmorrhiza. UMBELLIFER^. 261 



nearly 1^ lines lonj^, broadly ovate; ribs and broad oil-tii])os conspicuous: seed 

 nearly terete or soniewlmt hollowed on the face. 



Across the continent from New England and Florida to Wasliington Territory and the Sierra 

 Nevada ; Mono Pass (Hnlander), and rejiorted from Fort Tcjon, Xanhui. It is doubtful wliether 

 it extends to the coast, most of the specunens repoi ted fiom that region belonging apparently to 

 C. Californica. The species is also native of Europe and Asia. 



2. C. Bolanderi, Watson. Leaves bipinnate, the leaflets narrowly lanceolate, 

 sharply long-acuniiuate, two inches in length, very acutely serrate, the veinleta 

 passing to the sinuses ; the lower leaflets petiojulate and oi'ten d(>eply lobcd : in- 

 volucre of several linear leaflets : fruit two lines long, nearly orbicular, strongly 

 ribbed and with broad oil-tubes, which are sunk in tlie chiinnellod seed. — Proc. 

 Am. Acad. xi. 139. 



At Suisun, in salt marshes, Bolandcr. 



3. C. Californica, Gray. Very stout, 3 to 5 feet high : leaves pinnate, or the 

 lower bipinnate at base ; the leaflets 2 to 4 inches long, lanceolate, shortly acumi- 

 nate, rounded at base, serrate with the voinlets running to the teeth, often deeply 

 lobed on the lower side : involucre none, or a narrow leaflet ; involucels of several 

 lanceolate bracts : fruit broadly ovate, 1| lines long, strongly ribbed : seed not 

 channelled under the oil-tubes, rhomboidal or ovate in section, thinnest at the 

 commissure. — Proc. Am. Acad. vii. 344. 



In the neighborhood of San Francisco and southward to Santa Cruz (Ilartweg) and Monterey,

13. SIUM, Linn. Watf.k Parsnit. 



Calyx-teeth minute. Stylopodium dejjressed and styles short. Fruit oltlong or 

 ovate, laterally compressed with a narrow commissure, the ribs j)rominent and wing- 

 like, corky ; oil-tubes 2 or 3 in the intervals. Carjwphore 2-iiarted, slender and 

 usually deciduous Avith the fruit. — Smooth perennial aquatics, witli angled stems ; 

 leaves pinnate and leaflets serrate or pinnatifid ; involucre and involucels of several 

 bracts ; flowers white. 



Half a dozen species are found in the northern temperate zone and a single one in Soutli 

 Africa. The following sjtecies, also Asiatic, is the only one indigenous in Californin. 



1. S. Cicutaefolium, Gmelin. Stout, 3 to H f(>et high, branchiug: lower leaves 

 long-petiolcd, the caulino with a sluui dilated base ; leaflets fi to 8 jmirs, oblong- 

 lanceolate to linear, 2 to 4 inches long, acuminate, sliarj>ly serrate or i-arely pinnat- 

 ifid, the upper ones shorter and narrower: rays 1 to l| inches long; involucre 

 and involucels of 6 to 8 linear bracts : fruit oblong, l^ lines long, very strongly 

 ribbed. — S. lineare, Michx. 



Reported from Pose Creek, and mentioned by Torrey in Pot. Wilkes Kxped. and by Bolander 

 as growing near San Francisco. It is certainly found on the eastern slojie of the Sierra Nevada 

 in Sierra and Truckee Valleys, and thence ranges to Washington Territory, Colorado, the Sas- 

 katchewan, and the Atlantic. It is also identical with the plant of Siberia, the older name of 

 which is here adopted. Iknthnni & Hooker refer both this species antl the eastern S. Carxoni to 

 the genus yipium, but they are certainly not to be separated from the typical species i<f. lati- 

 JoHnm and landfolinm of the Old World. In all, the carpophore though delicate is always 

 2-parted, and the oil-tubes are 2 or 3 (perhaps rarely solitary) in tiie intervals. 



14. OSMORRHIZA, Hafinesque. Sweet Cicfxy. 



Calyx-teoth obsolete. Fruit linear-oblong, narrowly alleinmle at base, acuto 



above and tipped by the erect stylo, compressed laterally ami narrowed at the com- 



missuro; carpels 5-angled, with somewhat prominent slightly corky wings, his|)id 



with short ascending bristles ; oil-tubes numerous and very obscure. Seed terete,
