The numerous points of accordance, both in habit and struc- 
ture, evidently existing between Dumerilia and Jungia, induced 
me to suggest the probability of the identity of these two genera, 
in which opinion I was agreeably surprised to find myself anti- 
cipated by Sprengel; but the acquisition by this Society of the 
Linnean herbarium has afforded me the « opportunity of setting 
this question at rest by an examination of the specimen of the 
original species of Jungia described in the Supplementum Plan- 
tarum, which removes all doubt as to their identity. Several 
capitula being closely associated together at the extremity of 
the divisions of the panicle, and the presence of small bractez 
at their base, have no doubt suggested to Linnzus the idea of 
a compound capitulum.
