is from 300 feet in the lorsa tributary, to 1100 feet ou 

 the north side of the range of North Sannox, 



V. There are three varieties in Arran — (1st) the leaf 

 narrow, little cut, very white, downy underneatli, and 

 slightly downy on the upper side ; this is by much the 

 most rare : (2nd) that which has the largest leaf, not so 

 downy as the previous, pinnatifid, but seldom pinnate, 

 running however into the third : (ord) the three lower 

 segments of the leaf generally pinnate. 



VI. That the trees in the little stream at Catacol, where 

 there is proximity to the sea and the rock — not granite, 

 but a slate — are all of the third variety. 



VII. The form of the tree conforms to the shape of the 

 leaf. This is very notable in the first variety. In it the 

 leaf being narrow, the branches and twigs are slender and 

 drooping. 



VIII. The bloom of all is fragrant. 



IX. The range of the Eare Pyrus in Arran corresponds 

 to that of the Eed-berried Bearberry (ArctosfapJiylus Uva- 

 Ursi). This plant had previously been noted in the Holy 

 Isle. The writer was the first to notice it in Arran proper. 

 He now adds that he has found it in the neighbourhood of 

 all the habitats of the Eare Pyrus, and that he does not 

 know of it being found elsewhere in Arran. 



X. The known stations of the Eare Pyrus in Arran are — 

 (1st) the Allt-an-Champ, a tributary of the lorsa, fully two 

 miles south of Loch-na-Davie ; (2nd) a stream on the 

 northern 'slope, at the head of the North Sannox range ; 

 (ord) the three streams into which the Easan Biorach divides 

 at the foot of the steep slope to Loch-na-Davie, that on the 

 east being the lower part of the same stream mentioned in 

 number 2 ; (4th) the stream (not a tributary) at the mouth 

 of the Catacol ; (5th) the eastern head of the Catacol ; (6th) 

 the eastern tributary to it; (7th) the head of the Catacol; 

 (8th) Allt-na-Calmen, the Catacol's highest tributary — 

 ten stations in all. 



XI. In a letter to Professor Balfour, of which he was so 

 kind as send me a copy. Professor Koehne, of Berlin, 

 writes : " Messrs. Ley and Landsborough, if they search more 

 carefully, will find forms of the Eare Arran Pyrus, scarcely 

 to be distinguished from Surhv.s Aifcujxd-ia, since they have
