122 EUPHORBIA COROLLATA, 
Germ pedicelled. Capsule three celled. A 
great portion of the plants are wholly stamini- 
ferous. 
The results of a stinct chemical examination 
of this plant were very similar to these afforded by 
E. ipecacuanha. The ethereal solution was made 
turbed by alcohol, and the alcoholic by water, 
The precipitate in the last instance seemed 
denser and more abundant than it was in the 
former species. The decoction deposited a 
mucus or feculent substance, by means of alco- 
hol, as in the other plant. The same sweetish 
taste characterised the solutions of both yeg- 
etables. — 
‘Tt has been observed, by late experimenters 
in vegetable chemistry, that most of the lactes- 
cent or milky plants contain caoutchouc. . That 
they contain a substance of this nature, which. is 
dissolved by ether and. not by alcohol, I am able 
to attest from. the examination of various lactes- 
cent plants inserted in this work, and some 
others. ’ 
The properties of Euphorbia corollata haye 
been lately brought into notice by W. Zollic- 
koffer, M. D. of Baltimore, to whom I was first 
indebted for my specimens of the root and living 
plant ; and whe has furnished me with a yariety
