A NEW FLOEA OF 



Carduus arvensi,s.

The Xeropliilous species adapt themselves to the basalt and 

 porphyry to some extent, more so than to any other kind of rock 

 except limestone, a circumstance which would lead one to sup- 

 pose that it is the mechanical, rather than the chemical constitu- 

 tion of the rock, that is influential in attracting them. Besides 

 the four species marked with a star in the preceding list, five 

 others, AnthylUs vulneraria, Astragalus glycyphjUus, Ruhus saxa- 

 tilis, Origanum vulgare, and Polemonium cmruleum, have a fair 

 claim to be regarded as Cheviot plants ; and the same is true, 

 even to a still greater extent, with the basalt. The Cheviot 

 heights are much less heathery and more grassy than the sand- 

 stone moors, but they are almost as monotonous from the botanical 

 point of view, and totally destitute, still speaking botanically, of 

 any characteristic features. Take Cheviot itself for an example. 

 Although the hill rises very nearly to 900 yards, and there is a 

 wide extent of surface above 650 yards, we believe the following 

 to be very nearly a complete list of the plants which exceed the 

 latter altitude.
