Rediscovery of Crocus biflorus var. estriatus (Iridaceae) and its taxonomic characterisation

Collection: Pensoft Publishers

Keywords: Chromosome number · Topics: Saffron Plant Research Studies, Plant Diversity and Evolution, Plant and Fungal Species Descriptions

The Italian endemic Crocus biflorus usually shows white or lilac flowers with three-to-five striking violet longitudinal stripes on the outer tepals, but unstriped plants were recorded in the past. These plants were originally described as C. annulatus subvar. estriatus, and subsequently recombined as a variety of C. biflorus. The rediscovery of such plants in Toscana gave us the opportunity to clarify their systematic relationships, so that we typified the name, and performed karyological and ITS analyses. These plants share the same chromosome number (2n = 2x = 8) and ITS sequence with C. biflorus s. str.
