Art. XL Description of a Jfew Species of Gnaphalium, 

 hy Professor E. Ives. 



To B. Silliman, Esq. M.D., Src. 



X HE following description of a new species of Gnaphalium, 

 accompanied with a drawing, has been in my possession for 

 two years. If the Subsequent observations will be of use to 

 correct error, or solve doubts which maj-^ have existed con- 

 cerning some species of gnaphalium, they are at your service. 



E. IVES. 



This plant was first observed by me, in company with Mr. 

 C. Whitlow, in July, 1817, by the margin of a brook, a few 

 rods north of Mr. E. Whitney's gun manufactory, near New- 

 Haven. It is also found on the margin of the Housatonick, 

 about thirty miles from Long Island sound, where it was ob- 

 served by Dr. Alfred Monson, the last summer. Specimens 

 of this plant were sent to Z. Collins, Esq. of Philadelphia, for 

 the purpose of comparing it with the species of gnaphalium in 

 Muhlenberg's herbarium, more particularly with the Ivten- 

 album and Pennsylvanicum,w\\i.c\i. I had not seen.
