One of the most noticeable features in the Flora of North 

 America, as contrasted with that of the temperate Old 

 World, is the almost total absence of Primulas in the low- 

 lying regions of the western continent, and their rarity in 

 its mountains. The number of North American species 

 is only twelve, and are as follows. Three, all Asiatic, are 

 confined in America to the shores of Behring's Straits, 

 namely, P. nivalis, Pall., cuneifolia, Ledeb., and borealis, 

 Duby ; P. eyalUisensis, Hornem., is confined to Greenland, 

 and probably a form of sibirica, Jacq., which is widely 

 distributed in the Old World, but is Arctic only in 

 America. P. mistassinica, Micbaux, a European species 

 also Arctic in America, alone is found as far south as New 

 York and Lake Superior, whence it advances north to the 

 Arctic Sea, and turns south again along the Rocky Moun- 

 tains, but does not reach Colorado. The common European 

 P. farinosa is the most widely distributed of all American 

 Primulas, being found from Maine and Lake Superior 

 throughout the Arctic regions, and descending the Rocky 

 Mountains to Colorado. This leaves four species endemic in 

 Continental America, all confined to the Rocky Mountains, 

 namely, P. angustifolia and svffrutescens, neither of which 

 has hitherto been introduced into cultivation ; the lovely
