Hybridation en Corse et description d’un nouvel hybride:Anthyllis xgamisansii Delage et al. nothotaxon nov. (Fabaceae) (= A. barba-jovis L. x A. hermanniae L. subsp. corsica Brullo & Giusso)

Abstract : A new nothotaxon for the genus Anthyllis L., Anthyllis ×gamisansii Delage et al. (Loteae-Fabaceae)is described and illustrated. It results from a natural hybridization between Anthyllis barba-jovis L. and A. hermanniae L.subsp. corsica Brullo & Giusso. This hybrid, located at Cap Corse (Corsica, France), is compared with its parents using a multidisciplinary approach (genetics,morphology, karyology, phenology and fertility). These plants have a general appearance of Anthyllis barba-jovis, some intermediate parental traits and numerous characters of A.hermanniae subsp. corsica.Thisnew nothotaxon adds to the long list of Corsican hybrids. The origin and the role of hybridization in insular speciation processes are discussed.
