288 THE JOURNAL OF BOTANY 



Scotland. — Fei'thshive: Ben Lawers, 800-1000 m. ! 1911, 

 C. H. Ostenfeld. Ben Lui I 1912, W. G. Travis. Meall-nan- 

 Tarmachan \ 1914, B. C. Davie. Meall Garbh, 3000 ft., 1913 !

The specimens collected by Mr. McTaggart Cowan at Hope- 

 town, Linlithgow ! (Bot. Ex. Club Eeport for 1910, p. 555) and 

 referred by Mr. Druce (Journ. Bot. 1912, 201) to A. acutidcns, are 

 now named by Dr. Lindberg, A. alpcstris. With this view I 

 agree. I have not seen the Welsh specimens collected by Mr. 

 Druce (see Journ. Bot. I.e.), so the Carnarvonshire locality is 

 omitted for the present." 



Some confusion has been caused among British botanists by 

 the plants distributed in 1911 by Mr. Druce as A. vulgaris L. var. 

 acutidens from Ben Lawers, through the Exchange Club. Both 

 alpestris and acutidens grow upon this mountain, and there is no 

 doubt that both were dispersed through the Club, which accounts 

 for the diverse views expressed in the Report for 1911, p. 84. 



It may not be out of place here to draw up a short account of 

 the remaining British species : —

 V A. acutidens Bus. var. alpestriformis. 



A. MINOR Huds. Stems densely hairy, with patent hairs from 

 base to practically summit, usually scarcely diminishing in quan- 

 tity even at apex. Petioles densely hairy with patent hairs. 

 Root-leaves sparingly hairy on both sides, more densely on veins. 

 Pedicels and urceoles more or less hairy with patent, normally 

 plentiful, hairs. 



Reported or I have seen specimens from the following vice- 

 counties :— 3, 4, 5 ! 6 ! 7 ! 8 ! 9, 12 ! 14 ! 16, 17 ! 18 ! 20 ! 21 ! 22, 23,

Var. filicaulis Buser. Whole plant much less hairy, stems 

 and pedicels practically glabrous, urceoles sparingly hairy or 

 glabrous also. 



* Since these lines were written Mr. Druce has kindly sent me his Nant 

 Francon (Carnarvonshire) specimens collected in 1899. I fail to see how these 

 can be placed under acutidens.
