85. CYPEEACE.E. 63 



appeared better to refer this species to the English tj-pe ; 

 and tliis reference is further countenanced by the distri- 

 bution of the species bej'ond Britain. I met with it in 

 the Azore islands, far southward of Britain, but it is un- 

 known in the islands northward of Scotland, and occurs 

 in the Scandinavian peninsula only towards the southern 

 extremity.

Estimate of provinces 18. Estimate of counties 50. 



Latitude 50 — 61. British type of distribution. 



Agrarian region. Inferagrarian — Superagi'arian zones.

Native. Uliginal, &c. The estimate of 50 counties 

 only may appear low in the case of a plant which has a 

 provmcial generality, and which is distributed from the 

 extreme south of England to the extreme north of Scot- 

 land. But it is a plant which has usually had its locali- 

 ties reported by seekers for rarities, and has yet only 

 been recorded from about 40 counties, besides two or three 

 others in which it may have existed, although not now 

 foimd in them. Possibly, increasing knowledge may 

 eventually warrant an estimate of 60 counties, while it 

 scarcely does so at present.
