introducing some northern species of Rubus, would 

 result in giving the plant hardiness, in which case 

 it should become popular everywhere. Such a line 

 of experiment is well worth uhdertaking. 

 The Cloudberry 



In marked contrast to the Mayberry in point of 

 habitat and hardiness is the Rubus from the far 

 North that is commonly known as the Cloudberry, 

 or, in some regions, the bake-apple berry, and 

 known to the botanist as the Rubus chamemorus, 

 a name given to it more than a century and a half 

 ago by Linnaeus. 



The plant inhabits the peat bogs and similar 

 localities far to the North, even within the Arctic 

 Circle. Like many other arctic species of plants 

 it does not confine its habitat ta a single continent 

 but is found in northern Europ^ and Asia as well 

 as in North America. The same thing is true of 

 Arctic species of birds and animals; the obvious 

 explanation being that it is easy to wander from 

 one longitude to another in the regions where all 

 longitudes merge toward a common center. 



On this continent the Cloudberry extends 

 southward along the mountain ranges to Maine, 

 on the east coast, and on the west coast to South 

 British Columbia. 



The plant bears berries of the characteristic 

 Rubus type that are more commonly flattened
