  • Remarks

    JEANETTE

    Probably, forced by circumstances, not always the correct seeds of the type plant are spread; that's why in collections there are many plants with a anaberrant phenotype present.

  • Remarks

This plant clearly differs from the type that's discribed by Mr. Buining. Consequently the name-giving must be doubted.

In the past lots of plants with this phenotype were distributed with this name. It's recommended to collect again seeds of HU 198 in it's habitat and to sow them.
