Karyological study of some E Iberian threatened plants

Abstract

In the framework of cytogenetic studies of rare and threatened plant species of the Catalan Countries and surrounding territories, a karyological study of some taxa - three populations of Delphinium bolosii and the only known one of D. mansanetianum (Ranunculaceae), one of Hesperis laciniata subsp. laciniata (Brassicaceae), and one of Silene neglecta (Caryophyllaceae) - is presented here. Karyotype microphotographs and corresponding idiograms for most taxa are provided and their karyotype morphology is discussed.
