A contribution to the systematic relationships among some European taxa of genus Lilium

In this paper systematic relationships among several European taxa of genus Lilium are discussed, with special observations about the morphologically similar taxa belonging to the L. carniolicum group (L. pyrenaicum, L. carniolicum, L. bosniacum and L. jankae) that have historically been a cause of doubt or confusion. Another objective was to analyse the relationships between L. martagon and its close relative, a Dalmatian endemic taxa with an unclear taxonomic status, L. cattaniae. Combined analysis of the restriction-site variation of PCR-amplified cpDNA fragments (trnT-trnL, trnL-trnF and atpB-rbcL), mtDNA fragment (nad4 intron) and nrDNA ITS data was conducted as a first step towards a better differentiation of dubious taxa and to provide the basis for phylogenetic comparisons. The obtained restriction patterns effectively separated clear taxa, but provided no resolution of closely related taxa. The most systematically valuable was the ITS region which provided separation of clear taxa with all used restriction enzymes.
