NEW OB NOTEWORTHY SPECIES. 101 



very poorest herbarium specimens the two species are easily 

 distinguishable by the difference in texture and color of the 

 leaves^ as also by the number and size of the flowers ; while 

 no one who has seen the two alive, who knows their different 

 modes of growth, and the different duration of their foliage, 

 can possibly confound them. 



Ceanothus vestitus. Near C. cuncatus^ and lite it in size 



and habit : leaves and branchlets asliy-tomentulose, the former 

 opposite, coriaceous, subsessile, 4 to 6 lines long, round- 

 obovate, obtuse or retuse, someAvhat concave above, sharply 

 spinulose-dentate all around : flowers white : capsule ap- 

 parently small, the short salient appendages inserted at about 

 the middle. 



Borders of pine forests on the mountains near Tehachapi, 

 Ivern Co., Calif., 25 June, 1SS9 ; growing with C. mneahis, 

 the latter at that time with almost mature fruit, C. vestiiiis 

 being only well past flowering. 



Saxifeaga ledifolia. Near S. Tolmiei, but caudex mucli 

 stouter, its branches very leafy and not prostrate : leaves 

 spatulate-oblong, obtuse, entire, 6 or 8 lines long : peduncles 

 borne at tlie ends of leafy shoots, stout, 3 or 4 inches high, 

 bearing a rather close cyme of from 5 to 15 large flowers : 

 calyx nearly free from the ovary, the almost distinct sepals 

 <^rect : petals lanceolate, white : filaments dilated at summit : 

 carpels large, united at base, purplish. 



This plant lias been collected abundantly on the higher 

 niountains above Truckee, California, by :Mr. Sonne, and by 

 liim distributed as S. Tolmiei, from which it is distinguishable 

 at a glance by its much greater size and more numerous 

 leaves and flowers, even if one overlook the very radical 

 thfferences in its mode of growth and flowering. True S. 

 Tolmiei^ as I observed and collected it on Mt. Eainier, is a 

 ^'ery slender prostrate undershrub, whose filiform scapes 

 bearing only from 1 to 3 flowers, arise from the leaf-axils of
