174 ANNALS OF SCOTTISH NATURAL HISTORY 



under surface. Of it Professor Crepin remarked, " This 

 variation makes part of the series ' Subrubiginosa ' of Baker." 

 In I 894 I looked specially for this form, and found it widely 

 spread in Perthshire. This year (1895) I saw plenty of it 

 in other localities of Perthshire, but collected only three Nos. 

 Other five were gathered, two from Stirling and one from 

 each of the three counties mentioned last in the above list. 

 Of this year's gathering Professor Crepin says : " For some 

 numbers one cannot know whether the sepals erect them- 

 selves at maturity. I think that in certain forms of R. 

 coriifolia the sepals are somewhat late in becoming erect 

 after flowering, and that it is only at maturity that one can 

 judge as to their erection." 



From my own observation I can testify that certain 

 forms both of R. glauca and R. coriifolia are tardy in erect- 

 ing their sepals, and that mistakes may easily be made in 

 regard to this point, unless the bushes can be seen when the 

 fruit is beginning to redden, as well as in earlier stages. 



R. ARVENSIS, Huds. 



Specimens from three localities in Perthshire where I 

 found it naturalised. It is certainly not native in Perth- 

 shire, and very few of its fruits come to maturity in the 

 stations where I have observed it. 



R. ALPINA, Z., has kept its ground on Kinnoull Hill for 

 over twenty years ; and last year I found a bush of the 

 same species in Balruddery Den ; but of course the plant is 

 not native anywhere in Britain. 



R. HIBERNICA, Sin., var. glabra, Baker, has been gathered 

 at two stations near Dunkeld, at one by Mr. C. Mackintosh 

 in June 1883, and at the other by myself in August 1889, 

 but it has, I fear, been extirpated from both places. There 

 are, however, specimens gathered at the above dates in the 

 herbarium of the Perthshire Society of Natural Science. 



In my first parcel were four specimens which I sent 

 under the name of R. arvatica, Baker. In his report Pro- 

 fessor Crepin referred to these as being probably variations 

 of R. coriifolia, Fries, but said that it would be necessary 

 to study them anew on the living bush. This I promised to
