Description	The wild lettuce, Lactuca aculeata Boiss, is a robust and very prickly annual plant geographically restricted to the Near East and the Anatolian plateau. Israel is within the conjectured centre of origin of L aculeata, which is closely related and fully interfertile with cultivated lettuce, Lactuca sativa L. Twenty-eight L aculeata, five Lactuca serriola, and three putative hybrids L aculeata x L. serriola, i.e. total 36 accessions, representing 13 populations from Israel and 3 from Jordan, were studied. A highly homogeneous group of the 28 (ca 75%) L. aculeata accessions were grouped in one compact cluster, while the remaining accessions formed additional two smaller clusters with higher values of genetic distance indices. The five L. serriola accessions constituted the most distant cluster. Three accessions exhibiting a phenotypically intermediate character between L. aculeata and L. serriola, grouped together. They are considered natural putative hybrids of L. aculeata x L. serriola. The origin and evolutionary consequences of these hybrids are discussed.
