on the same sheet in Herb. Brit. Mus., gathered by him on Stuich 

 an Lochan, Perth. 



But there are still more interesting specimens in the same 

 rich herbarium, collected by Robert Brown on the ground at great 

 heights all over Ben Lawers in August, 1794. He had distin- 

 guished it as a new species and given it a manuscript name, and 

 had appended the following excellent description, which may 

 serve to diagnose S. scotica: — "Nimis affinis Saginae procumbenti, 

 differt praecipue floribus quinquefidis, decandris, pentagynis, cap- 

 sulis longioribus, statura majore, pedunculis longioribus et denique 

 statione alpina." 



S. scotica is not confined to Ben Lawers ; I have seen speci- 

 mens from Clova, Forfar ! Glen Callater, S. Aberdeen ! Glen 

 Ennich, Easterness ! Glas Thulachan, E. Perth, in Herb. Mus. 

 Brit. ; Craig Cailleach, Webb ; Stob Choire an Easain (in Herb. 

 Mus. Brit.) ; Ben Dothaidh ! Ben Loaigh, Argyll, Herb. Mus. Brit. 

 A large percentage of herbarium specimens of saginoicles really 

 belong to scotica, while a few specimens of scotica are also to be 

 found on sheets of proctimbens. 



ARCTIUM PERSONATA Mill, non L. 

 By James Britten, F.L.S. 



An accidental reference to Miller's Gardeners Dictionary 

 ed. 8 (1768) resulted in a somewhat curious discovery which, 

 so far as I am aware, has escaped the notice of botanists, British 

 and other, and to which it may be worth while to call attention. 



Of the genus Arctium Miller describes three species — A. 

 Lappa, A. Per sonata, and A. Tomentosis (corrected later to 

 Tomentosujn). " The two first," he says, " are common weeds, 

 growing on the sides of roads and footpaths in most parts of 

 England. . . . The second is by many supposed to be only a 

 variety of the first, but I have for several years sown the seeds 

 of both sorts in the Chelsea garden, where they have constantly 

 retained their difference, so may be allowed to be distinct species. 

 . . . The third sort is not a native of England. . . ." 



The description of the two first runs as follows : — 



•• 1. Arctium {Lappa) foliis cordatis inermibus petiolatis 

 capitulis majoribus sparsis. Burdock with heart-shaped leaves 

 without prickles, having footstalks, and large heads growing 

 scatteringly. 



" 2. Arctium {Per sonata) foliis cordatis inermibus, capitulis 

 minoribus compactis. Burdock with heart-shaped leaves without 

 spines, and small heads growing close together." 



These two names correspond with those of the two species 

 proposed by Linnaeus (Sp. PI. 816) and it may be assumed that 

 Miller intended them to apply to the same plants. But apart 

 from the fact that he does not (for either) quote the Sp. PI. in 

 accordance with his usual practice, it is obvious that in the case
