force. The remaining forty-five species are all strictly endemic, 
showing that the ancient connexion, of whatever nature it may have 
been, with America on the one hand or with Australasia on the other, 
has been so long severed as not to have left a single unmodified 
common form. The species are all either descendants altered by 
long isolation or possibly, in some instances, preserved remnants 
of types long since extinct elsewhere. 
2. Galapagos Islands. 
The flora of these islands is as well known as that of the Sand- 
wich Islands, and has been well illustrated by Hooker and after 
him by Anderssen. The following data are taken from his “ Vege- 
tation of the Galapagos ” in the *Fregatten Eugenies Resa,’ p. 65, 
with some slight modifications resulting from the researches of A. 
Gray and Hooker:—

The Galapagos, so much nearer to the American coast than the 
Sandwich Islands, are also much more decidedly American in the 
character of their Compositæ, although their affinity seems to be 
rather with those of Central America than of the more immediately 
opposite coast of Ecuador. A large proportion of the species are
