246 55. LAMIACE.E. 



Native. Sylvestral. The West Highland province has 

 been included in the estimate, although I find no certain 

 locality there on record. A species which occurs in La- 

 nark and Moray, and which ascends to 1000 feet and 

 upwards in the county of Perth, would seem very likely to 

 occur in Argyle or Dumbarton. 



816. Melissa officinalis, Linn. 



Area (1*3*5 6). 



Alien. Although not indigenous in Britain, this often- 

 cultivated plant appears to be in process of establishing 

 itself in the southern provinces. 



817. Melittis Melissophyllum, Linn. 



Ai-ea 1 2 [3] * 5 6. 



South limit in Cornwall, Devon, Hants, Sussex. 



N. lim. in Cardigan, Pembroke ? Glamorgan ? Gloucester. 



Estimate of provinces 4. Estimate of counties 8. 



Latitude 50 — 53. Atlantic type of distribution. 



Agrarian I'egion. Inferagrarian zone. 



Descends to the coast level, in the Peninsula. 



Ascends to 50 or 100 yards, in England. 



Range of mean annual temperature 51 — 49. 



Native. Sylvestral. The four counties named for the 

 southern limit of this species are certain, and have been re- 

 peatedly verified. Those mentioned for the northern limit 

 are on the authority respectively of Miss Atwood, for Car- 

 digan, — of Ray's work, repeated by subsequent wi-iters, for 

 Pembroke, — of the Swansea Guide, doubtingly quoted by 

 Dillwvn, for Glamorgan, — of Buckman's Botanical Guide
