THE BRITISH WILLOWS 



Argyll, Meall nan Tigearn ; Aberdeenshire, Little Craigindal. 

 Europe : Switzerland, Tirol, Norway, Sweden, Lapland. 



Sales Andersoniana x myrsinites x phylicifolia. 



Syn. S. nigricans x phylicifolia x myrsinites Seemen, iv. 

 240. 



Exs. E. F. & W. K. Linton, No. 73 (S. myrsinites forma). 

 Enander, Nos. 80-82. Hb. E. F. Linton, Nos. 135, 181 (4, 5). 



This resembles S. Andersoniana x myrsinites, but the leaf- 

 blades are of a brighter green, green and not glaucous beneath, 

 and not blackening much when dried, of firmer texture, much 

 sooner glabrescent, the ovaries are more densely pubescent usually 

 (as in No. 135), but may be less so (No. 181 (4) ). 



This triple hybrid has been found by W. E. Linton or 

 myself on Meall Ghaordie, Perthshire (No. 135), in Glen Fiagh, 

 Forfarshire (Linton exs. No. 73), and in Glen Callater, Aberdeen- 

 shire. No. 181 consists of a series raised from seed in the garden. 

 S. J. Enander has given me much assistance in naming these 

 plants. Europe : Prov. Herjedalen, Sweden.

A protean hybrid, of which several forms have been described 

 as species; consequently difficult to define. The evidence of 

 S. Andersoniana may be seen in the less polished bark of the 

 1-2-year old branches, their pubescence while young, the blacken- 

 ing of the + pubescent leaf-blades and their apical serration, the 

 more frequent presence of foliaceous stipules, and the reduced or 

 partial pubescence of the ovaries. 



The influence of S. phylicifolia appears in the presence of 

 some polish on the bark of the 1-2-year old branches, and their 

 rapid glabrescence ; in the modified blackening of the foliage 

 when dried and its quicker glabrescence, the subentire tip of the 

 blade, the reduced stipules, and the ovaries being partially or 

 altogether pubescent. 



The influence of each species varies so much and so unequally
