NOTES ON SCOTTISH ROSES 117 



writings on roses ; and to his generosity I also owe a fine 

 collection of species from the Alps. 



R. PIMPINELLIFOLIA, Linn. 

 6, from Mid Perth, West Perth, and Fife. 



Var. spinossissima,) Linn. 

 5, from Mid Perth and Fife. 



R. INVOLUTA, Sin. 

 9, from East Perth, Mid Perth, West Perth, Arran, and Ayr. 



In his first report Professor Crepin says : " I consider 

 most of the forms of which I formerly constituted the group 

 of Sabinicc to be R. pimpinellifolia X tomentosa. Four of 

 your Nos. have probably for their second parent R. 

 tomentosa. With regard to No. 22 (Auchterarder Station), 

 in which the sub- foliar glands are very abundant, these 

 glands extend likewise to the upper surface of the leaflets. 

 Can the second parent of this last hybrid be R. tomentosa ? 

 It is perhaps doubtful. 



" I advise you to observe closely what are the species that 

 exist in the neighbourhood of all the bushes of R. Sabini 

 that you know of, in order to ascertain what are the parents 

 of these hybrids. 



" Many varieties of Sabini<z have been figured or de- 

 scribed ; but it is very difficult to recognise them in nature, 

 because of the variations which bind them to each other. 



" During the coming season, make an attentive study of 

 all your forms, and prepare good specimens of them in 

 flower and in fruit." 



This I did, and sent numerous specimens from nine 

 different stations. Professor Crepin, in reporting on them, 

 said that he considered all of them to have R. tomentosa for 

 their second parent. With regard to the Auchterarder form 

 mentioned above, he wrote, in his " Excursions Rhodo- 

 logiques " for 1894, as follows: "A second form to which 

 I wish to draw attention has been observed by Mr. W. 

 Barclay at Auchterarder, in the county of Perth. It is 

 truly remarkable that I have seen nothing like it from
