50, GENTIANACE,E. 175 



Latitude 50 — 61. British type of distribution. 



Agrarian region. Inferagrarian — Superagrarian zones. 



Descends to the coast level, in the Peninsula. 



Ascends to 100 or 200 yards, in England. 



Range of mean annual temperature 52 — 45. 



Native. Pascual, Glareal. Rather a rare plant in the 

 four northern provinces of Scotland, where it appears chiefly 

 restricted to the neighbourhood of the coast. Only one 

 locality is mentioned for it in the Flora of Shetland ; and 

 it is quite omitted in that of Orkney. By its wide area, it 

 must be considered as belonging to the British type; 

 while, by its infrequency in the northerly provinces, it so 

 far inclines towards the English type of distribution. As 

 to E. latifolia, — there is such great uncertainty about most 

 of the localities recorded for it, whether they belong only 

 to broad-leaved states of E. Centauriura, or to something 

 really distinguishable therefrom, that I feel quite unpre- 

 pared to treat its distribution separately. By name, it is 

 reported from provinces 1,6, 7, 9, 11, 12, 16.
