The taxonomic status ofScilla beiranaSamp. ( Hyacinthaceae )

[摘要] Populations ofScilla beiranaSamp. were sampled in NW Portugal and compared with its relativesS. rambureiBoiss, andS. peruvianaL. Leaf and scape anatomy, morphology, chromosome number and idiogram were identical inS. beiranaandS. ramburei , but differed fromS. peruviana . Diagnostic characters previously used to discriminateS. beirana(width of leaves and flower number) showed continuous, but not clinal, variation, and failed to provide a clear-cut basis for identification and no other morphological attributes were found to separate the taxa. All available evidence suggests thatS. beiranashould be put into synonymy withS. ramburei , as was earlier suggested by COUTINHO (1935).
