of the latter. The late estimable Dr. Bromfield thought 

 J. diffusus a hybrid between J. glaucus and J. effusus ; but 

 with no sufficient gi'ounds to warrant the inference. In- 

 deed, although endowed with considerable acuteness of 

 mind, and a painstaking observer in botany. Dr. Brom- 

 field's mode of reasoning was often shallow and illogical ; 

 drawing inferences from imperfect or partial data, and 

 often such as by no means warranted the conclusions 

 formed on them, rather than from them. Making some 

 allowance for this their defect, the writings of Dr. Brom- 

 field were valuable contributions to the local botany of 

 England ; and his early decease was truly a loss to bota- 

 nical science.

South limit in Cornwall, Isle of Wight, Kent. 



North limit in Kincardine, Forfar, Perth, Lanark. 



Estimate of provinces 15. Estimate of counties 60. 



Latitude 50 — 57. English type of distribution. 



Agrarian region. Inferagrarian — Midagi'arian zones. 



Descends to the coast level, in the Peninsula. 



Ascends to 100 or 200 yards, in England. 



Range of mean annual temperature 52 — 47. 



Native. Inundatal, &c. The name of this species is 

 mentioned in a list of Orkney plants, on the authority of 

 a lady stated to be well acquainted with plants botanicallj'. 

 But those Isles are so far northward of any other locality 

 on I'ecord, that it appears better to consider that habitat 

 non-established, until some further information shall have 

 been obtained respecting the plant thus named. Possibly 

 J. balticus may occur in Orkney, and have been mistaken 

 for J. glaucus.
