Latitude 50 — 56. English type of distribution. 



Agrarian region. Inferagi-arian — Midagi'arian zones. 



Descends to the coast level, in the Peninsula. 



Ascends to 150 or 200 yards, in England. 



Range of mean annual temperature 51 — 48. 



Native } Rupestral and Glareal. Extremely pei-plex- 

 ing to decide whether and where this is native in England. 

 Most of the locaHties are expressly stated to be on walls 

 and banks, about villages and the ruins of old buildings ; 

 and such localities must be suspected in the case of a 

 plant so frequently cultivated in gardens. I have never

 cutting off the Scottish habitats, which appear still more 

 questionable than those in England.

Native. Rupestral. These two alleged species are to 

 me still inexplicable, and their localities inextricable ; and 

 cliiefly on this latter account I am under the necessity of 

 treating their distribution in combination. The "S. nipes- 

 tre," of English Botany, appears in my eyes to be simply
