Salices. 



My collection and examination of our native willows continue 

 to be a fruitful source of novelties. This year I have to announce 

 the discovery of two hybrid willows in my district. One, new to 

 science, Capreola + phylicifolia, is a triple combination, Aurita and 

 Caprea being equally conspicuous, Avhilst the other constituent is 

 phylicifolia. This interesting find occurred no further away than 

 at the New Loch, Thornhill. The other, from a sandbed in the 

 Nith near Waterside, Morton, is a hybrid between Purpurea and 

 Nigricans. The Rev. E. F. Linton informs me that although known 

 on the continent as Salix discolor, it is a new addition to the 

 British Flora. The double parentage, he also remarks, is well 

 seen in the foliage. Our district, as I mentiDued previously, is 

 apparently rich in purpurea hybrids. Some additional forms of 

 Secerneta, White (Purpurea + phylicifolia), have been found, which 

 are very curious and interesting. Other additions are forms of 

 Ambigua, Lutescens, and Oinerea, respectively determined as S. 

 spathulata, S. oleifolia, and S. aquatica of Smith. 



I have to express my indebtedness to Eev. E. F. Linton, of 

 Bournemouth, for critical help and for determination of the two 

 new hybrids. I may mention that the Rev. Messrs Linton, the 

 well-known botanists, have for the last ten years been making a 

 special study of British Willows, having collected and cultivated 

 all attainable varieties, and are about to issue prepared sets in 

 fascicles for the next four or five years, sending out a fascicle 

 annually. These sets well illustrate the latest scientific conspectus 

 of the genus, and I am arranging to have several of our Dumfries- 

 shire rarities included in the issue. I append our local list up to 

 date. The numbers attached are references to mj' herbarium 

 specimens.
