A study of populations of Tournefort’s Willowherb, Epilobium tetragonum L. subsp. tournefortii (Michalet) Lév., a non-native taxon naturalised in Cambridgeshire, revealed the presence of plants which on the basis of their morphology were attributed to hybrids with native willowherbs Epilobium parviflorum Schreb. (Hoary Willowherb), Epilobium tetragonum L. subsp. tetragonum (Square-stalked Willowherb) and Epilobium hirsutum L. (Great Willowherb). Details of distinguishing characters are given. The hybrid taxa have not previously been recorded as such in the British Isles.
