72 PITTONIA. 
A Srupy oF EvuTHAMIA. 
Two somewhat solidagineous herbs of eastern North America, 
closely enough allied in nature, but distributed by Linnaeus, the 
one to the South African genus Chrysocoma, and the other to — 
Solidago, were seen by the discerning eye and unbiassed mind of 
the gifted Nuttall to represent a proper genus. In the year 
1818 he published this new thought, assigning to the group the 
name KUTHAMIA. 
Altogether at variance with Solidago in habit and sufficiently 
well marked by several characters; much more nearly at agree- 
ment, habitally, with Gutierrezia, but necessarily separate from 3 
that group by its capillary rather than chaffy pappus, the genus 
is as definitely circumscribed as either Solidago or Gutierrezid, — 
and as certain to obtain future recognition as either of them. 
When eight years ago I was preparing to reinstate the then 
long suppressed EutHamta,' I became convinced that the list of | 
admitted species was greatly in need of revision; but the usual — 
grave difficulties to be surmounted in the way of identifying the 
original and typical species of the genus, at the time deterre 
me. Of success in that direction I am now more confident. 
The earliest mention that seems to have been made of any one 
of these plants is that of the Chrysocoma graminifolia, Lint. 
Sp. 841. The species is there published as new, and the name 
is accompanied by that which, for that particular author, is an 
uncommonly full and quite satisfactory description. It is 4 
northern plant; “Habitat in Canada, Kalm,” and, as I under- 
stand it, does not occur southward beyond New Jersey, and there 
only along the seaboard. 
E. GRAMINIFOLIA, Nutt. Gen. ii. 162, as to the name only.
