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 

 Linnaean 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- 

 iarum, 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 bracteae 

 at their base, have no doubt suggested to Linnaeus the idea of 

 a compound capitulum.
