Footnote 1:
This name has been wrongly given to some half-dozen different species;
but I am informed by Dr. Braithwaite (in lit. 29, Mch. 1872), that he
has recently consulted the original specimen of Dillenius on which
Linnæus founded the species, and from his examination the synonymy of
this group must be altered as above. The diagnoses of this and the
next four species are from his pen; the name _aduncum_ should be
retained as being older than _exannulatum_.
