it, the paper may thereforé be considered as the joint produc- 
tion of these two distinguished botanists; but about the same 
period Professor Lagasca published at Orihuela a. separate 
treatise on this family, which. he therein denominates Chenan- 
thophore, with the addition of a few more genera, and several 
of those occurring in the other memoir are there given under 
different names. ‘The names comprised in the memoir inserted 
in the ** Annales du Muséum" have however prevailed, from the 
more extensive circulation of the work, although the former 
has the right of priority by some months, as the latter occurs 
in the commencement of the nineteenth volume, which was 
published in 1812, the year after the separate treatise by Pro- 
fessor Lagasca had appeared. In the series of natural affini- 
ties the Labiatiflore form the connecting link between the Cicho- 
racez and Carduacee ; and although an exact definition of them 
is scarcely attainable, yet they appear to me sufficiently distinct 
to entitle them to rank as a separate family. Some botanists, 
however, have doubted of. the. » propriety | of this separation, and 
still think that they ought to be reunited to the other families of 
Composite ; but it is unnecessary here to argue against s such an 
opinion,—derived more, probably, from the works of others, than 
from actual observation,—as little investigation is requisite to 
see that by this reunion, the limits hitherto well-defined between 
the Cichoracee and Carduacee would be completely removed : 
and as no advantage whatever can be derived from this arrange- 
ment, it is crain prefere b to retain iem asa a distinct group, |
