Chromosome counts in the genus Festuca section Eskia (Poaceae) in the Iberian Peninsula

Emma Ortúñez, Vicenta de la Fuente

Open publisher page 24 citations

Abstract

Chromosome numbers of taxa of Festuca L. section Eskia Willk. in the Iberian Peninsula are given. The levels of ploidy for five taxa are confirmed. Idiograms and karyotypic formulae of the five taxa are presented for the first time. Two levels of ploidy occur in this section: diploid and tetraploid. One taxon, Festuca elegans ssp. merinoi is tetraploid and two other taxa have diploid and tetraploid populations. The remaining two taxa are solely diploid.
