Opuntiacex, Bignoniacee, and Lemnaces are the only three 
orders now added to the flora. Convolvulaceze are the family 
which, in proportion to extent, have received the greatest acces- 
sion of species, 5 being added to the 13 recorded by Mr. Bentham; 
whilst the 75 ferns have been augmented by 14. It is, however, 
probable that the number of Polygonaces, here increased by 2 
only, will be at least doubled. Something yet remains to be 
done for the perfect exploration of the island, the indigenous ve- 
getation of which is unfortunately suffering greatly from the 
unchecked operations of woodcutters; and there is perhaps at 
present not one resident who takes any interest in botany. There 
is little doubt that with a few active and observant amateurs at 
work the number of grasses and Cyperaces (plants so generally 
overlooked by collectors) would be somewhat added to, though 
both Mr. Sampson aud the writer have purposely paid much at- 
tention to these. Amongst Palms, there are at least three per- 
feetly distinct Calami, which require to be studied when in fruit. 
On the whole, the additions now made do not affect the conclu- 
sions arrived at by Mr. Bentham or alter the statistical relations 
of the flora as stated by him. There is, however, good reason to 
believe that the affinity of the South-Chinese and Japanese floras 
is greater than he supposed. The writer has already stated elsc-
