INTRODUCTION 



8. It will give some idea of the profound influence the conti- 

 nental glacier has probably had on the vegetation in the range to 

 record the large number of species that are now found only north 

 of the moraine. The following are unknown, in our area, south 

 of this line, although some are found further south in the moun- 

 tains outside of our region. Those marked with an asterisk have 

 been found only at elevations in excess of 1,000 ft.
