ADDITIONAL NOTES, ETC. 411 



add province 13 in tlie area. Mr. John Ball found it " by 

 the river Garry, north of Blair Athol" in Pei-thshu-e, 

 wliich may probably warrant a mean temperature as low 

 as 45.

 Probably the midarctic zone would be more correctly 



indicated for this species.

Province 6 may be added in the area, on authority of 

 Mr. Babington, &c. 



292. Arthroloh'mm ebracteatiim, vol. i. p. 312. 

 According to Mr. Elihu Berry, in Phytologist, iii. p. 386, 



this southern plant has been found in Yorkshire " on the 

 canal bank, by the Oakes-farm." Unless there has been 

 some error as to the species, we may presume it an intro- 

 duced plant there. 



293. Hippocrepis comosa, vol. i. p. 312. 



IMi'. J. T. Syme has seen a specimen of this plant, 

 gathered by Miss Boswell in the county of Kincai'dine, 

 " apparently quite wild." Judging by the altitude attained 

 in England, both Ayrshii-e and Kincardineshire would be 

 quite within the climatal range of the species. Mr. J. G. 

 Baker suggests that its range should be considered to ex- 

 tend to the arctic region, as it occurs at the top of Cronk- 

 ley Fell, although not quite at the highest part of the hill. 

 This altitude of 600 or 650 yards in the province of 

 Humber may be deemed about the limit or line of junction 

 of the agi'arian and arctic regions, corresponding with 400 

 or 450 yards in the East Highland pro^'iuce, about which 

 is found the upper limit of cultivation there. " Near Ayr, 

 Scotland " ; according to Brit. Flo. edit. 6.

Provinces (9) and (15) may be added, if worth while ;
