Ornithogalum (Beryllis) narbonense Linnæus 1756 (Asparagales Asparagaceæ Scilloideæ Ornithogaleæ)
[Ornithogalum Linnæus 1753: 213 (IT: 15) spp]
Recent phylogenetic analysis on tb Ornithogaleæ Rouy 1910 of molecular data in combination with matK, trnL intron, trnL-F spacer and rbcL plastid DNA sequence data has established that genus Loncomelos Rafinesque 1837 is a heterotypic synonym of genus Ornithogalum Linnæus 1753 in the section Ornithogalum. However, homoplasy is common in most monocots large ff/sff (Orchidaceæ, Amaryllidaceæ among others) and sf Scilloideæ Burnett 1835 is no exception. Contrary to arguments of Stedje 2001 and Manning & al. 2009, broader generic circumscriptions make it more difficult to understand relationships among spp groups from morphological and phylogenetic points of view since they underestimate the value of particular apomorphies. Recognition of groups which are too wide (such as Albuca and Ornithogalum in options 2 and 3 sensu Manning & al. 2009), although monophyletic, only increases heterogeneity in each and causes difficulties in morphological definition. Mono/oligotypic gg are not necessarily an inconvenience; in contrast, when small clades are well defined morphologically, molecularly and phylogenetically, they can merit generic rank, depending on the general criteria used. Therefore, genus Loncomelos sensu Martinez-Azorin & al. 2010 currently comprises only the 2 spp L. narbonense Rafinesque 1840 [ = L. brevistylum Dostál 1984 = O. pyramidale Linnæus 1753 = O. narbonense ssp. brevistylum Nyman 1882] and L. pyrenaicum Hrouda 1988, both previously included in sgg Beryllis and Eustachys sensu Zahariadi 1965, 1980 and subsequently grouped in the monophyletic genus Ornithogalum sensu Manning & al. 2009.
