 white, polygamous.

Mariposa Trail, among rocks, Bolander. 



A closely allied plant, but difTciing from any of the preceding genera, has been collected in 

 the Yosemite Valley by both Dr. Torrey and Dr. Gray, with the fruit however too immature for 

 its satisfactory determination. Tiie fruit as found is narrowly oblong, 4 lines lon<r, latenilly com- 

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

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

 angular facial sulcus ; carpophore 2-pai-ted. The idant is a foot high or less, glabrous, slender, 

 shortly caulescent ; leaves ternate or bipinnato, with linear acute segments, 1 to 3 lines long ; 

 umbels few-rayed, the rays very unequal, an inch long or less ; involucre none ; involucels of 1 

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



17. CENANTHE, Linn. 

 Calyx-teeth rather prominent, acute. Stylojiodium 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 iione. — Gla- 

 brous linrbs, mostly acpmtic ; leaves juiuinto or dccompouud ; undxds usually in- 

 volucrato ; flowers white. 



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

 in the temperate regions of the Old World.
