EQUISETUM HYEMALE, Z., IN WESTERNESS. 

 By ARTHUR BENNETT, F.L.S. 



So far as I know, the only records for this species in West 

 Scotland are Ayrshire (where it is named from five or six 

 parishes, of which Tarbolton is the most westward), and 

 West Sutherland (A. Gray, " Trans. Bot. Soc." Edinburgh). 

 It was recorded by Mr. Croall (" Record Club Rep. for I 876," 

 (1877), p. 174), from Easterness ; and though this vice-county 

 is mainly eastern, yet at one point it almost runs out to the 

 western seaboard. Kirkcudbright and Lanark, in which it 

 also occurs, can only be called Central Scotland, though each 

 are partly west of the median line. 



Last August my friend Mr. C. E. Salmon gathered it on 

 Culvain (3224 feet), in the parish of Kilmalie, at an altitude 

 of 1750 feet ; this exceeds by 850 feet any record known to 

 me. In the " Comp. Cybele Brit." the highest record is 

 600 feet, " Baker in Humber." But in Baker's " Lake 

 Flora," p. 247 (1885), he gives it for 900 feet, "between 

 Shap and Anna Well, I. Lawson." 



In the "Flora of Perth," p. 374 (1898), it is given for 

 " low levels " only ; in Dickie's " Bot. Guide to Aberdeen, 

 Banff, and Kincardine," p. 236 (1860), the altitude noted is 

 i 50 to 400 feet. In "Top. Bot," ed. 2 (1883), the record 

 for S. Aberdeen is marked doubtful. 1 



In Scotland this species extends north to about N. lat. 

 58 30'. In Finland it grows in two of the north-west pro- 

 vinces (Lapponia inarensis and L. tulomensis) to about 69 



1 The localities named in the " Bot. Guide" are all either in Kincardine or 

 in N. Aberdeen. I have not myself seen it in S. Aberdeen. ). W. II. TRAIL.
