Hybrids Vaccinium x intermedium Ruthe (= Vaccinium vitis-idaea x Vaccinium myrtillus) occurs very locally with the parents in Staffs, Derbys and Yorks, with old or unconfirmed records elsewhere, but is absent from most areas where the parents cohabit; it is convincingly intermediate in all leaf, stem, flower and fruit characters and sets some good seed. Chromosome number: 2n=24. |
