Verspreiding in Nederland (toelichting) |
Although Meikle states that this hybrid is generally less frequent than S. caprea x viminalis this remark does not fit to the situation in Holland. The increase shows 4 5x5 kilometre squares before 1990 and 131 5x5 kilometre squares since; but the identification of this hybrid and S. x sericans is often questionable (see under the latter) and so are the distribution data. The date mentioned above (1855: IJsselmuiden – det. Jansen & Wachter 1906 was confirmed by A. Neumann). |
