 along the Columbia River, under overhanging cliffs, in Multnomah 

 Co., Howell. — This must rank near E. Philadelphicum.

FiLAGO DEPRESSA. Soror F. Californicce, sed a basi ramosissima, 

 humistrata, internodiis omnibus brevibus ; bracteis fl. foemineis angus- 

 tioribus ; acheniis obovatis laevibus. — Desert of San Bernardino Co., 

 California, at Hot Springs, &c., Parry., 1876 (incomplete specimens),

Gnaphalium pannosum. Lana densa undique incanum ; caulibus 

 e radice annua vel lignescente adscendentibus pedalibus simplicibus ; 

 foliis spathulatis, radicalibus amplis obovatis triplinerviis (pollicem

 Luis Potosi, Schaffner, 227. Parry ^ Palmer, 420. Habit unlike 

 any of the ordinary Mexican species. 



Gnaphalium Arizonicum. Griseo-lanatum ; caulibus gracilibus

* The Mexican species greatly need revision, and the collocation of original 

 specimens. 



G. oxYPHYLLUM, DC. To this is referred no. 551 of coll. Palmer, a woolly 

 form, from near Saltillo, where Gregg collected a form (415) with the wool 

 deciduous, and the somewhat viscid hairiness well developed. Of the same 

 species are Coulter's 451, Parry & Palmer's 417, specimens from Botteri, and 

 one received from Schultz Bip., collected by Schaffner at the foot of Chapul- 

 tepec, and ticketed " G. hirtum, HBK." It may be so; but the leaves are not 

 glaucescent beneath, nor the involucral bracts " argute acutis flavescentibus." 

 The G. inornatum, DC, of which no authentic specimens are at hand, may be a
