Salix ×cottetii Lagger ex A.Kern. is a frequently cultivated willow worldwide.
It represents a prostrate plant suitable for rock, alpine, or small urban gardens.
Our comparison of original material of S. ×cottetii, which was used by Kerner
for the description of this willow, with cultivated plants showed that the name
Salix ×cottetii was misapplied to a prostrate clone from Europe, as well as to
an upright plant called S. ×cottetii ‘Bankers’, which was promoted in the
US for erosion control. A specimen of Salix ×cottettii stored in WU is designated
as the lectotype to ensure the correct application of the name S. ×cottetii
to the cultivated, prostrate plants. It is proposed that the clone cultivated in
the US as S. ×cottetii ‘Bankers’ be referred to as S. ‘Bankers’
until its parentage is determined.
