F CtAYTONiA CHSNOPODiNA. A caulescent perennial, the 



several leaves and scapes of equal length and about 3 inches 

 high, arising from a fascicle of several rather thick and fleshy 

 roots : leaves from subhastate-ovate in the earlier, to ovate 

 without basal angularity in those next the scapes : bracts of 

 the involucre ovate, sessile as it were at summit of scapes, the 

 subumbellate cluster of flowers as if sessile within the involucre 

 and barely equalling it : corolla of the size and form of those 

 of typical Claytonia and pinkish : seeds not seen. 



Mono County, California, at 10,500 feet in the mountains, 

 growing in volcanic scoriae, collected 4 Aug., 1912, by Messrs. 

 Hatton and Maule, in the Forest Service there. The plant is 

 very fleshy, and as a species is strongly characterized by its 

 fleshy and fascicled roots and the chenopodiaceous cut of its 

 main foliage. 



\ 



Tridophyi^LUm achemii<i,aceum. Biennial, more than a 

 foot high, parted from near the base, and somewhat dicho- 

 tomously, into numerous slender upright cymosely panicled 

 branches : basal leaves on slender petioles 1/4 to 3 inches long, 

 leaflets 3, closely approximate, the terminal obovate, the late- 

 rals gibbously round-obovate, all coarsely crenate-serrate, 

 sparsely and minutely pubescent above, the lower face and 

 petioles villous and viscid ; leaves of flowering branches 

 smaller, cuneate-obovate, entire below the middle, all the axils 

 bearing both a solitary rather long-pedicelled flower and a 

 much longer suberect floriferous branch, all branches and 

 branchlets polished and straw-colored at first view, under a 

 lens seen to be viscid: flowers very small, no petals seen; 

 segments of calyx deltoid-ovate, bractlets narrow, elliptical, 

 yet nearly equalling the segments ; achenes minute, subreni- 

 form-oval, smooth, whitish. 



Collected by the writer at Golconda, Nevada, 28 July, 1896 ;
