262 18. GERANIACEiE. 



species is native or alien in England. If not originally a 

 native it has become sufficiently well established in several 

 localities to create a claim to the designation of ' denizen.' 

 In Scotland its stations ai-e more liable to suspicion ; and 

 there it might be fakly enough classed with the aliens. 

 The authorities for its occm-rence in the provinces of Trent 

 and Lakes, require to be corroborated. In that of Tyne, 

 both Mr. R. B. Bowman and the late Mr. Winch pro- 

 nounced it " naturalized." In general, the proximity of 

 old gardens, and the scanty numbers of the plants, throw 

 doubt on the nativity of the localities ; so that I can re- 

 gard it only as a naturalized alien in Britain. 



233. Geranium ROTUNDrFOLiuM, Linn. 



Area 12345* [7 8* 10 (11) * * 14]. 



South limit in Devon, Isle of Wight, Kent. 



North limit in Suffolk, Northamptonshire, Wai-wickshire ? 



Estimate of provinces 5. Estimate of coimties 15. 



Latitude 50 — 53. English type of distribution. 



Agrarian region. Inferagrarian zone. 



Descends to the coast level, in the Peninsula. 



Ascends to 50 or 100 yards, in England. 



Kange of mean annual temperature 52 — 48. 



Native. Rupestral or Glareal. The recorded localities 

 are to be received with distrust, other species having fre- 

 quently been mistaken for the present. All the provinces, 

 from North Wales to the East Lowlands, may be consider- 

 ed to require confiinnation, before the present species can 

 be deemed really native in them ; but the fact of its oc- 

 currence about Gateshead, in the Tyne province, is Mly 

 proved by specimens collected there by Mr. Storey, of 

 Newcastle, although probably the species was originally
