Abstract

Allozyme electrophoresis is used to evaluate the allozymic diversity of two vascular plants endemic to the Catalan Countries, Seseli farrenyi Molero & Pujadas (Apiaceae) and Petrocoptis montsicciana O. Bolòs & Rivas Martínez (Caryophyllaceae). The study of P. montsicciana has been combined with that of P. pardoi Pau, since they are considered synonymous in the most recent taxonomic treatment. 14 loci have been interpreted in S. farrenyi and 16 loci in the two Petrocoptis taxa. The high levels of genetic diversity found in the three taxa are surprising, far exceeding those expected for endemic species, especially in the case of S. farrenyi. Data about population structure are given for the taxa studied and, finally, the main threats to these species are enumerated and conservation strategies are suggested.
