GENEEAL REPORT. 
XXXV 
Species, thirteen are not know on the Pacific side — of these five are arctic 
and three subarctic, and of the remainder forty-one are arctic and twelve sul)- 
arctic. Six species are Mexican. 
In determining the alpine or subalpinc character of a species, exposure, 
altitude, and season have all been taken into nccoiiiil. In llic absence in 
many cases of any forest growth to indicate the limit of aflnjeeseeiil v<'o<'|;i- 
tion and, independently of altitude or the protection of trees, the lloni of .my 
mountain locality being greatly influenced by a warm and sniiny exposnre or 
the opposite, the question has often been very mncli one of jn(li:nienj, lo be 
decided by no single arl)itrary consideration. Species (»!' donldinl nnik as 
alpine, or evidently only approaching \\, have been consi<leiv(l siihalpine, and 
those that were also found at lower elevatiofis than ell her term wonM imply 
are indicated by an asterisk. The numher of alpine and snhalpiia' species 
(114) equals that of the arctic and snharctie, hut lliey an- (piiie dill'erently 
distributed, the large majority behmging to lln; second ratlier than th<' third 
division.
