Salix myrsinifolia x phylicifolia (S. x tetrapla)
An erect shrub or small tree of damp rocky ground, river-banks and lake shores. It is found where both parents are present, often in populations showing a complete range of intermediates between them, and also in the absence of S. phylicifolia in highland Scotland. Generally lowland, but upper altitudinal limit unknown.
This hybrid was not mapped in the 1962 Atlas, and there is no evidence to assess changes in its distribution. It is probably under-recorded.
Frequent in N. Europe. In Fennoscandia, as in Britain, it is fertile and backcrosses to its parents are more frequent in some areas than S. phylicifolia, or occur in its absence (Jonsell, 2000).
