Verspreiding in Nederland (toelichting) |
After being introduced for use around 1920 it appeared that all known plants were female, probably representing one clone; the most likely parentage seems to be S. caprea x S. cinerea x S. viminalis, because up to some degree the characters of all three are present. Therefore distribution data, like most other Salix-hybrids are far from reliable and should be regarded with utmost care. The date suggested 1905 above is linked to a specimen in herb. Jansen & Wachter (L. 3164535) and was confirmed by A. Neumann in 1961. |
