Mono Pass {Bolandcr) ; in the Southern Sierra Nevada, Rothrock. The thick root is said not 

 to be sweet-scented. 



21. CYMOPTERUS, Raf.

 ovate or elliptical, obtuse or retuse, dorsally flattened, the lateral ribs and some or 

 all of the dorsal ones expanded into more or less thickened and corky wings ; oil- 

 tubes narrow, one to several in the intervals. Seed dorsally flattened, and more or 

 less concave on the face. Carpophore 2-parted. — Perennials, mostly low and often 

 cespitose, with a thickened root ; leaves piunately and finely decompound, witli 

 small narrow segments ; umbels usually both involucrate and involucellate, few- 

 rayed ; flowers white or yellow. 



Natives of Western North America, about 1.5 species, most of them confined to the region 

 between the Rocky Mountains and the Sierra Nevada. The roots are extensively used by tlie 

 Indians for food.

 at base : leaves rather rigid, thrice pinnate ; leaflets a line long or less, linear-oblong,

One of the most widely distributed of the species, ranging from the Cascade Mountains in 

 Washington Territory to Ebbett's Pass {Brewer, at 9,000 feet alt), and the Yosemite Valley 

 {Gray), and in the mountains eastward to Colorado. As in other species the number of developed 

 dorsal wings is variable.

2. C. montanus, Xutt. Xearly acanlescent : leaves clustered at the summit of 

 the very short stem, smooth and glaucous, pinnate or bipinnate, the oblong seg- 

 ments pinnatifid with oblong obtuse entire or toothed lobes : peduncles 1 to 4 

 inches high, rather stout : involucre and involucels of broad and membranaceous 

 bracts, united at base, the involucre often short and cup-like : rays about half an 

 inch long or less ; pedicels a line or two long : fruit 3 to 6 lines long, with thin flat 

 wings 1 or 2 lines broad ; calyx-teeth small ; oil-tubes 3 in the intervals, 6 to 8 on
