this country, formed it into a distinct genus, which he called 
Adina. Sir James Smith reduces Adina to Nauclea. To 
ourselves it appeared, while unacquainted with the fruit, 
to be in nowise distinguishable from Cephalanthus, from 
which we still think that nature has not divided it. Upon 
inspection, however, of the fruit, of which there are speci- 
mens in the possession of the Horticultural Society, it 
proves to be in the structure of its pericarpium more nearly 
related to Nauclea, from which it only differs in dehiscence, 
and in the small number of its seeds. We therefore coin- 
cide with the opinion of Sir James Smith, remarking only 
that this and another species with which we are acquainted. 
seem to confirm the opinion entertained by some botanists 
of authority, that Cephalanthus, Nauclea, and Uncaria can, 
with Adina, be maintained only as sections of the same 
natural genus. 
The unpublished species to which allusion has just 
been made is also a native of China, from whence we have 
specimens in fruit. It resembles N. Adina entirely in 
habit, but differs from it in the outline of its leaves, and in 
the great length of the peduncles. It may, therefore, 
be called : mn 
N. Adinoides; foliis obovato-lanceolatis glabris, capi- 
tulis axillaribus foliis duplo longioribus, pericarpio tenui 
oligospermo.
