| Abstract: | A new species of the section Spartopsis Dumort. of the genus Cytisus Desf. (Fabaceae) is described. The new species, Cytisus insularis , is restricted to the western islands of Galicia (north-west Iberian Peninsula), where it principally colonizes cliffs. A possible recent hybrid origin for these populations is considered but rejected in view of the results of experimental tests of pollen viability and seed germination. Characters permitting discrimination from the most similar taxa are detailed, and possible relationships with the other species of the section are discussed. |
