A STUDY OF EUTHAMIA. 73 
minate, only the midvein obvious, glabrous on both faces, rather 
obscurely punctate, the margins minutely scabrous-serrulate, 
the midvein beneath with some few scattered very short hairs 
like those of the margin: branchlets of the inflorescence glab- 
rous except as showing faint scaberulous angles: bracts of the 
involucre obtusish, thickened and green toward the summit, 
strictly erect. 
s above intimated, this northern plant, to which Nuttall 
applied the name, is not at all what he described under the name, 
in his Genera. ; 
E. Nurrari. F. graminifolia, Nutt. 1. c. as to the descrip- 
tion, not Chrysocoma graminifolia Linn. (but possibly Solidago 
lanceolata, Linn.) Commonly 3 or 4 feet high, the very leafy 
stem both striate-angled and minutely rough-pubescent: leaves 
of a peculiar somewhat coppery deep green, 3 inches long or 
more, spreading on the stem, lanceolate, acute, the lowest usually 
5-nerved, the middle ones 3-nerved, all nearly glabrous above, 
obscurely punctate, sparsely strigose beneath except as to the 
veins, these hispidulous, the margins merely scabrous: short 
subcorymbose inflorescence very wide, often a foot across, its 
branches and branchlets strongly hispid-hirtellous; involucres 
more narrowly turbinate than in the last, their tips more thick- 
ened and greener, strictly erect. 
This is the common, and the only Huthamia of at least the 
upper Potomac Valley, in Virginia and Maryland, extending to 
southern New J ersey and Pennsylvania ; doubtless also further 
northward and southward. I dedicate the species to the author 
who first described it. That it can be the same as Solidago 
lanceolata, Linn. seems altogether improbable ; for that, accord- 
ing to his brief account of it, has a subsquarrose involucre, and 
leaves that are more roughened on the margin than otherwheres, 
while in our plant the only pronounced roughness is along me 
veins beneath. Though I doubt altogether that Linneus 
C. graminifolia and S. lanceolata are, as most authors have as- 
sumed, the same thing, yet I am unable to make out, to my own 
satisfaction, what his S. lanceolata really is.
