range, above Alta, at over 12,000 feet altitude; Marcus E. Jones, 

 August, 1879. 



Saxifraga eriophora. Radical leaves oblong-ovate, dentate, 

 obtuse, glabrous above, reddish and more or less densely rufous- 

 tomentose beneath, the broad petiole equalling the blade (about | inch 

 long) and ciliate with long woolly hairs : scaj^e glandular-pubescent, 

 the flowers subcymose, with linear-lanceolate bracts: calyx glabrate, 

 broadly campanulate, the purplish lobes broad and rounded, half the 

 length of the spatulate pinkish petals : ovary 2-parted, adnate to the 

 calyx at base. — On the northern slope of the Santa Catalina Moun- 

 tains, Arizona, at 6,000 feet altitude ; J. G. Lemmon, May, 1881. 

 Resembling S. Virginiensis and S. nivalis. 



Sedum divergens. Perennial, the rather stout stem 2 to 4 inches 

 high : lower leaves broadly ovate or obovate, sessile, 3 or 4 lines 

 long, the cauline narrower and somewhat spatulate : inflorescence 

 close, with short branches : flowei's yellow, pedicellate, the lanceolate 

 petals (3 lines long) thrice longer than the triangular-ovate sepals, 

 and equalling the stamens : carpels united at base, very widely diver- 

 gent above. — In the Cascade Mountains, Washington Territor}' ; on 

 Mount Adams, by W. N. Suksdorf, September, 1880, and by myself 

 near the summit of Yakima Pass, October, 1880. 



Sedum divaricatum. Perennial and cespitose, with slender 

 branching rootstocks, the lower rosulate leaves oblauceolate, obtuse 

 or acutish, roughish on the margin, 6 lines long or less: flowering 

 stems 2 to 8 inches high, with scattered oblanceolate leaves, or the 

 upper leaves and bracts lanceolate : inflorescence umbellate, the 

 branches once forked : flowers nearly sessile, bright yellow, with 

 short lanceolate sepals and narrowly lanceolate acuminate petals : car- 

 pels broadly divergent above the united bases. — Collected by W. C. 

 Cusick in Union County, Oregon. These two species resemble in 

 their spreading carpels S. Douglasii, which is distinguished by its 

 lanceolate acuminate leaves. 



Cotyledon viscida. Shortly caulescent : leaves numerous and 

 very viscid, linear to linear-lanceolate, attenuate upward and obtusely 

 triquetrous, the outer about 3 inches long : flowering stems slender, 

 a foot high, with similar leaves | inch long : flowers in a spreading 

 cymose panicle, on pedicels 1 or 2 lines long ; sepals purplish, ovate- 

 lanceolate, 1-|- lines long, the reddish corolla cleft to below the 

 middle, 4 lines long and equalling the stamens and styles. — Abundant 

 on rocks near the Hot Springs at Sau Juan Capistrano, Los Angeles 

 County, California; Rev. J. C. Nevin, October, 1881.
