514 Guppy . — Testimony of the Endemic Species of the Canary 
A. 
Distribution in the Canary Islands of Macaronesian endemic species 
— that is, of species restricted to that floral region, but shared by the 
Canaries with other Macaronesian groups (Azores, Madeiras, Cape Verdes). 
There are seven principal islands.

There can, therefore, be no doubt that in the Canaries the endemic 
species that also occur outside the archipelago in the other Macaronesian 
groups have a much wider distribution than those restricted to the islands, 
range in the group going with range in the whole floral region, as Dr. Willis 
has established for New Zealand. We will now ascertain how botanists 
have explained the origin of the two kinds of endemic species. In the first 
place we will deal with the Canarian endemics proper. Hooker had long 
been interested in the floral history of the group. He gave it a prominent 
place in his Lecture on Insular Floras in \ 866, and twelve years later he 
gave his matured views in the appendix to the joint work by Ball and 
himself on ‘ Marocco and the Great Atlas’ (p. 417). For him the endemic 
species peculiarly Canarian came into being as derivatives of parents of 
Mediterranean type that reached the islands long ago. As an example 
of the prevailing methods and * generally accepted views ’ among systematists 
in the latter half of last century Hooker’s remarks have great importance 
in connexion with the subject of this paper, and they are here quoted 
in full : 
‘ The wonderful development in the Canaries of endemic species, 
belonging for the most part to Mediterranean types, points to the very early
