“…Allium, and sect. Codonoprasum in particular ( Ce smed ziev & Terzijski, 1997;Neshati & Fritsch, 2009;Celep et al, 2012). Diagnostic differences among the related taxa mainly regard variation in seed size and in shape and size of testa cells, as well as in microsculpturing of periclinal walls with reference to number, shape and distribution of papillae.…”

Allium paniculatum L. is commonly recorded from the Euro-Mediterranean and Irano-Turanian regions. Evidence from literature and herbarium collections revealed that many different taxa of A. sect. Codonoprasum Rchb., all characterized by big size, diffuse and densely flowered umbrella, very long spathe valves, long pedicels, and cylindrical-campanulate perigon, have been wrongly attributed to this species thus affecting records on its geographic distribution and morphological characterization. In order to define the true identity of A. paniculatum, we analyzed specimens coming from the type locality (Don River), and provided details on morphology, ecology, karyology, leaf anatomy, seed morphology and seed coat micro-sculpturing. Taxonomic and phylogenetic relationships with related species of sect. Codonoprasum and with other taxa of different sections were investigated by means of morphological characters and molecular data from the internal transcribed spacers (ITS) nrDNA and the trnH-psbA cpDNA region. Maximum parsimony and Bayesian inference analyses of molecular data recovered two main clades in A. sect. Codonoprasum and clearly separated A. paniculatum from related taxa. The taxonomic implications of these patterns of relationships are discussed. To our knowledge, this is the first study documenting in-depth phylogenetic relationships within A. sect. Codonoprasum.Key words: Allium paniculatum, A. sect. Codonoprasum, karyology, morphology, phylogeny, seed coat sculpturing, taxonomy.For a long time Allium paniculatum L. has been regarded as a remarkably variable species, counting a wide range of morphologically different forms. More than thirty taxa, at specific or lower rank, were included into the A. paniculatum complex, many of which have been gradually recognized as species. The most relevant diacritic characters of this group mainly regard gross size, length of spathes, shape of inflorescence, shape and morphology of some floral traits (Levan, 1937;Wilde-Duyfjes, 1976;Stearn, 1980). Describing A. paniculatum, Linnaeus (1759, pp. 978) just provided this short protologue: "A. caule subteretifolio umbellifero, pedunc. capillaribus effusis, stamin. subulatis, spatha longissima", which was also quoted in Linnaeus (1762, pp. 428). These few diagnostic characters often caused erroneous attributions of specimens and, based on literature and herbarium surveys, several taxa of A. sect. Codonoprasum Rchb., which usually exhibit big size, many-flowered and spread inflorescences, long pedicels, very long spathe valves, and cylindrical-campanulate perigon, have been improperly referred to A. paniculatum. As a matter of fact, the name A. paniculatum has been mistakenly applied to samples of A. dentiferum Webb & Berthel., A. fuscum Waldst. & Kit., A. oleraceum L., A. pallens L., A. tenuiflorum Ten., etc. (Brullo et al., 1991(Brullo et al., , 1996(Brullo et al., , 2001(Brullo et al., , 2003(Brullo et al., , 2008a).Due to these frequent misleading interpretations, main floras and taxonomic revisions on the genus...

Allium efeae Özhatay & İ.Genç is described as a new species from northwest Anatolia. The distribution area of this species is restricted to Kıbrıscık (Bolu) and Beypazarı (Ankara). It resembles Allium lycaonicum Siehe, but differs in tepal shape and color, leaf length, and filament shape. A table comparing the diagnostic morphological characters of the new species and A. lycaonicum is provided. The diagnostic morphological characters, distribution, conservation status, and color photographs of the new species as well as its chromosome number (2n = 24) are presented.

Allium undulatitepalum (Amaryllidaceae) is described as a new species from the Antalya Province of Turkey. It belongs to the section Melanocrommyum and is endemic to the south-western region of Turkey. The new species is a close relative of A. orientale, but according to results of the ITS sequences, and based on the morphological differences presented in the description, it is clearly different from its relative. A phylogenetic tree, distribution map, illustrations, pollen and seed microphotographs, karyo-morphology, as well as notes on the biogeography and ecology of the new species are provided.
