scarcely suflficient for reliance while unsupported by the 

 production of specimens. I am almost afraid that the 

 provinces of the Peninsula and Lakes may turn out to be 

 errors also ; but they are retained for the present. I feel 

 equally unprepared to fix the altitude of the stations, and 

 their character, whether pascual, glareal, or otherwise.

Estimate of provinces 7. Estimate of counties 15. 



Latitude 50 — 55. Atlantic (?) type of distribution. 



Agrarian region. Inferagrarian — Midagrarian zones. 



Descends to the coast level, in the Peninsula. 



Ascends to 50 or 100 yards, in the province of Thames.

Native. Pascual and Glareal. Could we satisfactorily 

 assign to their proper species the localities recorded for 

 this and L. perenne, it seems highly probable, that the two 

 species would be found correctly referred to the Germanic 

 and Atlantic types ; but in trusting to published localities, 

 each one appears to intrude, here and there, by isolated 

 habitats, within the area of the other of them. If it be 

 correct that L. angustifolium occurs in Suffolk, Norfolk 

 and Yorkshire, its distributive type will come nearer to the 

 'English,' than to the ' Atlantic'
