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.
