Wild hybrids issued from crossing European species of genus Erica L. are described. The close study of the type material of Erica ϫlazaroana Rivas Goday & Bellot (Erica arborea L. ϫ Erica umbellata L.) shows that it should be regarded as a new synonym of Erica arborea. Erica ϫnelsonii Fagúndez (Erica cinerea L. ϫ Erica tetralix L.), a new nothospecies from Ireland, is described from herbarium material. Erica ϫveitchii nothosubsp. asturica Fagúndez (Erica arborea ϫ Erica lusitanica subsp. cantabrica Fagúndez & Izco) is also described. A study of seed micromorphology shows evidence of hybridization between Erica tetralix L. and Erica ciliaris L.
