Those species enumerated in tlie column of upper 

 limits, it is to be understood, have not yet been ascer- 

 tained to rise above the zone under which their names 

 are placed. Those enumerated in the column of lower 

 limits, on the contrary, have not been ascertained to 

 descend heloio the zone in which their names are placed. 

 It is not very certain that the six species first named in 

 the column for lower limits, are absolutely restricted to 

 the superarctic zone. They are very rare even there, and 

 extremely rave below, if found lower at all. The species 

 enumerated for the inferagrarian zone, in the other 

 column, are all rare ; no plant generally diffused through 

 that zone being quite restricted thereto. The Clematis 

 was adduced in volume first, as one of the most charac- 

 teristic plants ; and it is certainly more frequent and con- 

 spicuous than any of those enumerated above. But it has 

 been lately claimed as a plant of the Yorkshire flora ; and 

 if rightly so claimed, it must be deemed to occur within 

 the midagrarian zone also, although locally restricted, 

 and only slightly within that zone. 



All species found at or near the coast-level, southward
