probably two distinct species different from those described above. 
From the imperfect material examined and the meager descriptions it 
is evident, at least, that they cannot be Zi/@opsts lineata——JouN M

A NEGLECTED NORTH AMERICAN EUPHORBIA. 
(WITH PLATE 111) 
Ir is with considerable hesitation that the writer ventures to describe 
another species in this large and complicated genus, the specific limi- 
tations in which, so far as our American representatives are concerned, 
are so very imperfectly understood. The particular form in ques- 
tion, however, stands out so sharply from its near relatives that one 
seems entirely justified in treating it asa distinct species. The plant 
was noticed several years ago growing upon dry waste soil about Ithaca, 
N.Y. Not far distant were specimens of both £. maculata and £. 
nutans, from which it differed so greatly in appearance that a more 
Careful study was made of it during each succeeding summer, the final 
result being that other characters were found to support this difference 
n general appearance, which are noted in the following description. 
The history of the American species of the section ANISOPHYLLUM 
has been very much involved since the earliest times, principally because 
the early botanists did not understand the value of the fruit and seed 
characters used so much at present. The types of the older species 
are therefore exceptionally vague.
