749. Veronica triphyllos, Linn. 



Area * * [3] 4 [5] * * * * 10. 



South limit in Suffolk and Norfolk. 



North limit in York. 



Estimate of provinces 2. Estimate of counties 3. 



Latitude 52 — 54. Local (Germ.) type of distribution. 



Agrarian region. Inferagrarian — Midagi-arian zones. 



Descends to the coast level, or nearly so, in Ouse. 



Ascends to 50 yards, more or less, in England. 



Range of mean annual temperature 49 — 48. 



Native. Glareal, Agrestal. Local, though rather less so 

 than V. verna. Like the latter, it occurs in some few 

 localities in Suffolk and Norfolk ; also, about York and 

 Doncaster. Its extension into a second province, still 

 eastern, takes it one step farther from the strictly Local to- 

 wards the Geimanic type of distribution. Enumerated in 

 Cooper's list of Metropolitan plants, and in Purton's Mid- 

 land Flora ; — en-oneously in both instances, I fear. Possibly 

 the temperature might have been indicated to range down- 

 wards to 47, considering the inland position of the York- 

 shire habitat.
