SALIX 
65 
S. cinerea x viminalis is rather local but widespread in lowland localities, as in osier-beds, by stream-sides, 
and in hedgerows and woods on damp alluvial soils; from the Channel Isles, Cornwall, and Suffolk, northwards 
to Perthshire and Sutherlandshire. 
Scandinavia, Denmark, Germany, Belgium, France, central Europe, Russia; Turkestan to the Amur region. 
S. purpurea* viminalis (see page 68); S. repens x viminalis (see page 51); triandra x vimi- 
nalis (see page 24).

This is the most specialised series of the genus Salix, as is shown by the remarkable androecium : it is natural there- 
fore to place the series at the end of the genus.
