- To investigate the biosystematic and genetic relationships among Sicilian species of Genista sect. Voglera, four populations of three species, Genista aristata C. Presl, Genista cupanii Guss., and Genista madoniensis Raimondo, have been studied. Genista madoniensis is tetraploid, with a chromosome number of 2n = 48, as are the other two species. An isozyme study showed that G. madoniensis is taxonomically closer to G. aristata than to G. cupanii, the latter possessing four unique alleles. The results are discussed in the context of the ecological characteristics of each species.
