300 58. PRIMULACE^. 



Agrarian region. Inferagi-arian — Midagrarian zones. 



Descends to the coast level, in the Peninsula. 



Ascends to 100 or 200 yards, in England. 



Range of mean annual temperature 51 — 47. 



Native. Pratal, Paludal. Uncertain as a native of Scot- 

 land ; but there scarcely appear grounds for distrust suffi- 

 cient to justify a rejection of the Scottish provinces and 

 counties altogether from the estimated census, &c. It is 

 said to occur in Dumfries (Lightf Flo. Scot.), Lanark 

 (Flo. Lan. and Flo. Glott.), Roxburgh (Rev. James Dun- 

 can), Berwick (Dr. G. Johnston, in Flo. N. D.j, Edinburgh 

 (Mr. Thomson, in Graham's Excurs.), and on shady banks 

 of the Esk, Forfarshire, abundantly (D. Don, in Hook. Flo. 

 Scot.) ; but it is altogether omitted from Gardiner's Flora 

 of Forfarshire.

South limit in Cornwall, Isle of Wight, Kent.

Estimate of provinces 17. Estimate of counties 75. 



Latitude 50 — 58. British type of distribution. 



A. A. regions. Inferagrarian — Midarctic zones. 



Descends to the coast level, in the Peninsula. 



Ascends to 800 yards, in East Highlands. 



Range of mean annual temperature 51 — 38. 



Native. Sylvestral. According to the Summa Vegeta- 

 bilium of Fries, it would seem that Lysimachia nemorum is 

 more exclusively a plant of the austral type in Scandina- 

 via, than is the L. nummularia. In Britain, as will be seen 

 from the formula, their differences are just the reverse ; L. 

 nemorum being far the more widely and generally distri- 

 buted of the two species.
