Abstract

Comparative anatomy of leaf cross sections of fourteen Ornithogalum taxa is carried out: O. orthophyllum subsp. baeticum, O. collinum, O. comosum, O. divergens, O. exscapum var. exscapum, O. exscapum var. ambiguum, O. exscapum var. parlatorei, O. gussonei, O. montanum, O. kochii subsp. monticola, O. refractum, O. televrinum, O. umbellatum 3x (= O. angustifolium), O. umbellatum 4x (= O. vulgare). Analytical drawings are presented. Thirteen noteworthy leaf characters were quantified, organized in a data matrix (two more Ornithogalum species from literature were added) and finally analyzed through Neighbour Joining (NJ) and UPGMA methods. Leaf features in Ornithogalum result useful in order to group species, while often are not sufficient to characterize each single taxon.
