Abstract


A new triploid agamic species, L. leonardi-llorensii, is described from coastal populations of South-West Mallorca. The new species is closely related, on morphological grounds, to the endemic L. marisolii L. Llorens, from which it could be distinguished by several morphological characters (leaves without papillae, longer calyx, more flowers per spikelet) and by a different chromosome number (2n = 26, L. leonardi-llorensii; 2n = 27, L. marisolii). The relationships between both species are discussed, and it is suggested that both taxa might share some common evolutionary history despite their divergent chromosome number. The origin of L. marisolii from L. leonardi-llorensii through chromosome fission or by a hybridization event is considered.
