122 ANNALS OF SCOTTISH NATURAL HISTORY 



equally a plant of Scotland and of the north-west of France (where 

 O. cruenta also occurs), so that too great stress must not be laid on 

 its distribution. 



O. rnbra certainly occurs near Oban, whence came specimens 

 now in Herb. Brit. Museum. 



O. cruenta belongs to a section of the genus in which there are 

 no other British species ; and it seems to be an exceedingly variable 

 plant on the Continent. ARTHUR BENNETT. 



Alehemilla alpina, L., and A. conjuneta, Bab. Mr. Druce, in 

 the January number of the " Annals," quotes Mr. H. Boswell as 

 having produced in his garden A. conjuneta, Bab. from A. alpina., 

 L., from Ben Lawers. 



My experience of the two plants is by no means the same. I 

 have had A. alpina, L. (also from Ben Lawers), for eight years, and 

 A. conjuneta for sixteen years, and in neither case is there the slight- 

 est reversion, one towards the other. A. conjuneta seeds much more 

 freely than alpina; but both produce seedlings, which I have watched 

 through to the flowering stage. A. alpina does not bear our dry 

 Surrey climate so well as conjuneta, which grows remarkably well 

 here. A. alpina from Shetland (but kept two years only) also 

 shows no sign of any approach to conjuneta. 



And in none of the numerous specimens of alpina from Scotland, 

 the Faroes, Iceland, or elsewhere, have I seen any real approach to 

 conjuneta, such as would lead one to suppose that the one could be 

 produced from the other. None the less I do not mean to dispute 

 that conjuneta may only be a variety of alpina ; that is another 

 matter. ARTHUR BENNETT. 



[My experience with plants of A. alpina and of A. conjuneta 

 during six years in my garden in Old Aberdeen agrees with Mr. 

 Bennett's. J. W. H. TRAIL.] 



Plants of Glen A'an, Banffshire. In August 1891, in company 

 with Mr. G. H. Robertson, a few hours were spent in examining 

 the precipices on the south and west sides of the glen which 

 encircles Loch A'an. We had crossed over by the east side of 

 Cairngorm, and found that side poor in plants. The precipices 

 near the head were richer ; as also were the shelving rocks down 

 which a stream, fed by the snow on Ben Muic Dhu, falls into the 

 loch. 



Arabis petrcea, Lamk., occurred on the south side, as did also 

 Cerastium arcticum, Lange, which is probably the C. latifolium of 

 " Top. Bot." C. alpinum occurred on the north side of the glen, on 

 Cairngorm ; as did Rhodiola rosea and Samsurea alpina, DC. 

 Trollius europceus and Cerastium trigynum occurred on the south 

 side ; and towards the head of the glen Cryptogram me crispa, Athy- 

 rium flexile, Phleum alpinum, very rare, and Alopecurus alpinus, also
