80. GRAHnNA. 167 



Ascends to 350 or 400 yards, in Lake province. 



Range of mean annual tentiperature 51 — 44. 



Native. Sylvestral. The North Isles is enclosed in 

 the line of area, because the Milium has been reported 

 only from the " mill-dam, Pabdale," in Dr. Gillies' un- 

 published Flora of Orkney. There seems here the double 

 chance of error, that the species may either have been 

 mistaken, or otherwise have been introduced to the sta- 

 tion given. Widely diffused in Scandinavia ; absent from 

 the Faroe list ; re-appearing in that of Iceland plants. 

 Thus, there would be no geographical presumption against 

 the occurrence of this grass in Orkney, were it known in 

 the North Highlands, or in other groups of the province 

 of the North Isles.

Ascends to 100 or 200 yards, in England. 



Range of mean annual temperature 50 — 48. 



Colonist. Agrestal. Abundant in sandy fields in some 

 counties of the Thames and Ouse provinces, where it is 

 perfectly established as a weed, if introduced in times long 

 past. Very local in the province of Channel, and perhaps 

 limited to that particular portion of it, in North Hants, 

 which physically forms part of the Thames basia, although 

 adherence to county boundaries will unite that portion
