Hab. With the preceding.-Although mixed with the foregoing species by Mr. Douglas, it must have 

 been so through inadvertence ; for the two species are totally distinct in their foliage. With regard to the 

 genus of these plants, I cannot satisfy myself that they should be referred to Eriophjllinn of Lagasca a 

 native of South America, and of which the characters are most imperfectly detailed. The involucre in oVr 

 individuals IS not monophyUous, assuredly ; though from the dense covering of wool, it may have the appear- 

 ance of beinfr so. ^*^
