NOTES ON ABERDEENSHIRE ROSES 43 



R. INVOLUTA, S/ll. 



Nos. 21, 57, 69. 



Nos. 21, from near Ellon, and 57, from Aberdour, are on the 

 whole similar. The former has the leaflets less hairy and more 

 glandular on the under side, and the fruit much more bristly than 

 the latter. In both the heteracanthy is distinct on the flowering as 

 well as the barren branches, and the sepals are almost quite simple. 

 Probably both are hybrids between pimpinellifolia and tomentosa, 

 but it is not safe to dogmatise on this point without studying the 

 bushes in situ. It is possible enough that mollis might be the 

 second parent. 



No. 69, from near Turiff, appears to be very different. It puts 

 me very much in mind of R. pimpinellifolia x rubiginosa ; but the 

 specimens are not sufficient to decide the matter, and therefore 

 I reserve my opinion till I can see better specimens, or, if possible, 

 the bush itself. 



R. HI BERN i CA, Sm. 



Var. glabra, Baker. 

 Nos. 55, Si. 



These two specimens of this rare hybrid come from widely- 

 separated localities the former from Gamrie, Banffshire, the latter 

 from St. Fergus, Aberdeenshire. This forms, I think, a new record 

 for both counties. 



Both Nos. correspond closely in all essential points with speci- 

 mens which I possess, some gathered by myself, and others received 

 from correspondents. No. 55 has the prickles on the barren stem 

 much denser, and the main ones much larger than No. *8i. In 

 both, though the prickles are somewhat deflexed, there is scarcely 

 any perceptible curvature. There is decided heteracanthy on the 

 flowering as well as on the barren stem. Leaves with nine leaflets 

 occur on both, but are most numerous on the former, which seems 

 to have been in more vigorous growth. On No. 55, which was 

 gathered on 24th August, there is but one fruit, well developed as 

 regards size, and with the sepals, which have one or two very slender 

 pinnae, closely reflexed. On number Si, which was gathered on the 

 26th October, there is one not well-developed fruit, still green, and 

 also with reflexed sepals. Wrapped in paper are two fruits from the 

 same bush, which have reddened. On these the sepals, much 

 shrivelled, seem also to be reflexed, and to be quite persistent. On 

 opening one of these fruits I found only one achene, apparently well 

 formed. We may conclude, then, that these bushes, though they 

 may flower profusely, are almost quite barren, as is usually the case 

 also with R. involuta. 



From the reflexed sepals one is seemingly driven to the con-
