44 ANNALS OF SCOTTISH NATURAL HISTORY 



elusion that these two bushes must be hybrids of R. pimpinellifolia 

 and a form of canina, probably of the group lutetiana. As R. glauca 

 is much more abundant in the district than R. canina, one would 

 have rather expected R. glauca to be the second parent. 



[A brief statement of the local distribution of the Roses 

 referred to by Mr. Barclay may be of use. They were, with 

 few exceptions, collected in the district of Buchan as now 

 limited, i.e. between the rivers Ythan and Deveron. This 

 area lies in H. C. Watson's vice-county (93), N. Aberdeen, 

 except that in its north-western angle the entire parish of 

 Gamrie and two small portions of Alvah belong to Banff 

 (94). In Aberdeenshire Buchan are eighteen entire parishes, 

 ten along its coast, and portions of six which are intersected 

 by the Ythan. Buchan as a whole is poor in Roses, especially 

 in its central and north-eastern parishes. The valleys of 

 the Deveron and Ythan, and the sea-coast parishes of Gamrie 

 in Banff, and Aberdour in N. Aberdeen, form exceptions to 

 this poverty. In the valley of the Ugie they are much less 

 frequent. I am glad to have this opportunity to express 

 my thanks to Mr. Barclay for the great trouble he has taken 

 to determine the forms represented in the gatherings. 



The distribution is indicated under vice-counties 92 (S. Aber- 

 deen), 93 (N. Aberdeen), 94 (Banff), by parishes, under the river- 

 basins and along the sea coast. Under each parish the species 

 observed in it are enumerated, the numbers quoted above by Mr. 

 Barclay being stated for each species. A few species are merely 

 named under some parishes without numbers, having been seen 

 but not collected there.
