Potentilla and Fragaria (Rosaceae) reunited

Abstract

Because morphological, genetic and DNA evidence shows that Fragaria is nested in Potentilla, the former is referred (following Scopoli 1760) to the latter. Remarks on the value of broad generic concepts permitting infrageneric units to be recognized on non-morphological characters are presented. A formal description of the ‘intergeneric’ hybrid to which the cultivars ‘Serenata’ and ‘Frel’ are referred, P. x rosea Mabb., is provided. New combinations and a nomen novum in Potentilla (P. x ananassa (Rozier) Mabb. [the commercial strawberry], P. chiloensis (L.) Mabb. [one of its parents; new lectotype], P. daltoniana (J. Gay) Mabb., P. iinumae (Mak.) Mabb., P. nilgerrensis (J. Gay) Mabb. [new lectotype] P. nubicola (Hook.f.) Mabb. [new lectotype], P. pentaphylla (Losinsk.) Mabb., P. silvanus Mabb. [Fragaria tibetica] and P. yakusimensis (Masam.) Mabb. [F. nipponica]) are made in a list of species and commercially significant hybrid strawberries generally referred to Fragaria. Some authorities and places of publication of names in current use are also amended.
