Native. Rupestral. Apparently restricted to the one 

 locality of Cheddar Cliffs, in Somerset; and not having,, 

 seen that station, I am unprepared to say anything about ^""''-2/^ 

 the altitude at which the plant grows. Among the many ^ ^' 

 botanists who have visited the spot, not one of them would 

 appear to have had any larger or superior idea than that of 

 collecting a rare species. Such is human nature, however. 

 A thousand will do over again, or say over again, that 

 which has been done or said before ; but scarcely one in a 

 thousand will start a new idea. The botanical mind offers 

 no exception in this respect. A thousand will go and col- 

 lect ov^er again a rare species discovered by a predecessor ; 

 but scarcely one in a thousand will inquire into or examine 

 the conditions under which it exists.
