The Wahlenbergias represent in the southern hemis- 
phere the Campanulas of the northern, and the little species 
here figured so closely carries out the generic representation, 
that it bears the name of the Blue-bell in the New Zealand 
Colonies. Its only near ally is the common W. agrestis of 
Australia and New Zealand, which is a tall slender 
branched leafy plant, with much smaller flowers ; but it is 
so very variable in all respects, that I have ventured to 
think that W. sazicola may be a mountain form of it, 
characterized, like so many alpine forms of lowland plants, 
by the reduced stem and leaves and larger higher-coloured 
flowers. In fact, our own Blue-bell (Campanula rotundifolia) 
has varieties quite as different from one another as Wahlen- 
bergia saxicola is from W. agrestis, and the differences are 
of the same nature. This view is in some respects sup- 
ported by the fact of W. saxicola and agrestis both growing 
in Tasmania, where the former is as abundant a lowland
