The type was obtained along the roadside near Ukiah, Men- 

 docino county, California, July ii, 1902, only a few specimens 

 collected. In general appearance it resembles such species as 

 N. mellita and N. squarrosa, 



Aloysia Wrlghtii (Gray) 



Lippia Wrightii Gray, Amer. Journ. Sci. II. 16: 98. 1854. 



Anaphalis sierrae 



Stems from running rootstocks, 5 or 6 dm high, rather 

 weak, simple, clothed with a close cottony pubescence, leafy 

 throughout: leaves thin, pubescent like the stem, but much less 

 so, the upper side dull green, only scantily pubescent, the lower 

 side paler but not white, indistinctly 3-nerved, oblong-lanceolate, 

 acute and shortly apiculate, the larger ones on the middle part 

 of the stem about 7 cm. long, i cm. wide, those above and below 

 somewhat smaller, all sessile, the lower ones somewhat narrowed: 

 heads several, corymbose-cymose, the peduncles and pedicels 

 densely short woolly: bracts of the involucre numerous, pearly 

 white, ovate, oblong, 4 mm. long, 2 mm. or more wide, obtuse 

 or merely acutish. 



The type is my no. 71 16, collected along the wagon road 

 between Donner Lake and Donner Pass, at about 6500 feet, 

 growing among shrubs, the rather weak stems somewhat sup- 

 ported by them. It was distributed as A. stibalpina^ the type 

 of which came from the Rocky mountains, but differs from that 

 species in its thinner, less pointed leaves, dull instead of light 

 green above, and in the less ample inflorescence with smaller 

 flowers and less pointed involucral bracts. H. E. Brown's 551 

 freni Mt. Shasta is the same, and no doubt all the specimens of 

 this genus from the Sierra Nevada should be referred here.
