70 44. COMPOSlTiE. 



Ascends to 100 or 200 yards, in England. 



Range of mean annual temperature 51 — 47. 



Native. Glareal, Agrestal. Locally abundant in some 

 counties of the Thames and Ouse provinces ; but with very 

 few localities on record, and for single counties each, in 

 those of the Channel, Peninsula, Severn, and Trent. It 

 reappears in a few localities near the coasts of the East 

 Highlands ; namely, in Moray and Aberdeen, under sus- 

 picion of having been introduced to those two counties ; 

 also, in Forfarshire, under circumstances which give greater 

 probability of its being truly indigenous there. Mr. G. 

 Don states, with reference to the lower parts of Forfarshire, 

 that " when any muir ground is broken up, although there 

 is no symptom of its having been ever ploughed, this plant 

 never fails to make its appearance the first year ; but after 

 the field has been cultivated for some time it begins to dis- 

 appear," This observation holds good if applied to wastes 

 in some of the sandy tracts in Surrey; but diligent search 

 on neighbouring ground, still left unworked, will discover 

 usually some few very diminutive examples of the species. 

 The Arnoseris is scarcely a plant of the superagrarian zone, 

 although the low district of Moray may be considered just 

 within that zone of vegetation.
