long, wide, margined petioles which enlarge at base becoming 

 sheath-like; blade of the upper leaves lyrate-pinnatifid, with 

 rather long, tapering apex, no terminal lode, all points acute, 

 thin blades \y 2 to three inches long, usually as long as petiole; 

 whole plant softly villous with flatfish, tapering, spreading hairs; 

 slender calyx tube 2 inches long, gradually enlarging above; 

 flower bud elliptical-oblong, about an inch long, tips not free nor 

 evident, lobes linear in flower and an inch long; petals obcordate, 

 yellow, 1 to ij4 inches long, reddening with age, vespertine; 

 stigma lobes linear and anthers broadly so; capsule from lance- 

 olate-conic to linear-lanceolate, 12 to 21 lines long, tapering from 

 near the base, but apex not narrowed to a long tip, tip often 

 short and thick, pod sharply 4-angled and rarely a little winged 

 at the widest part, center of valves with a thick rib, margins 

 with a filiform rib, reticulations scarcely evident, with scattered 

 stiff hairs and minute rather than dense pubescence usually; 

 seeds in 2 rows, closely packed, oblong, would be sub-cylindric 

 were it not for a warty raised area covering % of the back, the 

 smoother margin indistinctly pitted and wider above, about i}4 

 lines long, face with narrow groove below and opening into a 

 deeper, rounded depression above. 



This grows in the hot sand on the upper edge of the Larrea 

 belt at about 5000 ft. alt., on Darwin Mesa, Argus Mts. Inyo Co. 

 Cal. Collected May 8, 1897. This approaches CE. xylocarpa 

 Coville and CE. primiveris Gray, but it grows in a wholly dif- 

 ferent zone from the former and the seeds are different. 



Peucedanum NeVADENSE var. cupulatum n. var. Bracts of 

 involucels united into a cup with hyaline margin, 3 to 4 lines 

 long, oil tubes 8 to 9 on the commissure. Collected at Reno, 

 Nevada, June 19, 18S2, and April 22, 1897, at 5000 ft. alt. on 

 gravelly mesas. 



Peucedanum juniperinum n. sp. Nearly a foot high, from 

 a tuberous root; stems single or few, purplish; nodes none or 2 

 to 3, and usually shorter than the enlarged sheathing petioles; 

 the lowest internode often 1 to 2 inches long; leaves ternate to 

 biternate with the divisions bipinnate, final divisions almost
