Solanum elaeagnifolium Cav. (Solanaceae), an unrecorded naturalized species of Korean flora

ABSTRACT: We report a naturalized alien species, Solanum elaeagnifolium Cav. from Chodo Isl., Samsanmeon,Yeosushi, Jeollanam-do province. The native distribution range of the species is the southwestern US and theadjacent region of northern Mexico. The species is related to S. nigrum L., but the species can be distinguishedfrom S. nigrum by the silver green stellate trichome on the surfaces of plants, the elongated leaf shape, and thesize and color of the flowers and fruits. Solanum elaeagnifolium Cav. belongs to the Solanum subgenus Lep-tostemonum. The species is recorded on the invasive species list in the subtropical or temperate regions of manyEuropean, Mediterranean, African, South American, Asian, and Australian countries. Therefore, we also need acareful monitoring and prevention strategy for this new invasive species in Korea.
