Guadalupe, hence with our northern group. From the presence 
of a few sporadic South American forms it would be as unsatis- 
factory to attempt in any way to connect their floras as to deduce

Have these islands ever formed part of a continuous territory ? 
Have they ever been united to the adjacent continent? Is their 
antiquity greater or less than that of the main and? 
These, and a host of correlated questions, must first be an- 
swered authoritatively by the geologist who undertakes their care- 
ful exploration ; until then the botanist must relegate the history 
of the past to the field of idle speculation, and from the pregnant 
material at hand confine himself to defining the present—antici- 
pating the future.
