“…Costatae, especially regarding the total number of bundles (50-54) and vascular rings (3-4), bundles of the outer ring (26-32), as well as diameter of cross-section (2.5-3.7 mm) and pith parenchyma (2.3-2.8 mm) (Table 3). These findings corroborate our previous results assessing anatomical characters of outer bulb tunics (Khorasani et al 2018), but contradict the recent classification of Fritsch and Abbasi (2013), that separated A. hooshidaryae from the A. stipitatum complex and referred it to A. section Pseudoprason. The taxonomical studies of Wendelbo (1971) classified A. giganteum along with other members of the A. stipitatum complex in A. sect.…”

“…These findings are in agreement with our previous study suggesting the transfer of A. orientoiranicum to A. subsect. Elatae based on bulb tunic anatomy (Khorasani et al 2018). The distribution and orientation of vascular bundles in the cross-sections of scapes have previously been used for dividing 22 species of A. sect.…”

“…The most recent taxonomic treatment (Fritsch and Abbasi 2013) Previous morphological and anatomical studies have provided characters useful for separation and delimitation of subgenera, sections and species in Allium. Characters of high taxonomic importance are provided by leaf anatomy (Saghir and Mann 1969, Tanker and Kurucu 1981, Miceli et al 1984, Fritsch 1988, Uysal 1999, Yousaf et al 2008, Özdemir et al 2008, Draghia et al 2013, Mashayekhi and Columbus 2014, Li et al 2010, root anatomy (Uysal 1999, Özdemir et al 2008, Draghia et al 2013), rhizome and bulb anatomy (Jaccard and Frey 1927, Mann 1952, Huang and Sterling 1970, Gregory 1996, Prychid and Rudall 1999, Shrestha 2007, Rola 2014, Khorasani et al 2018, seed morphology (Neshati and Fritsch 2009, Bednorz et al 2011, Celep et al 2012, Lin and Tan 2017, ovary surface micromorphology (Gurushidze et al 2008, Choi et al 2011 and scape anatomy (Jacobsen 1979, Fritsch 1992, 1993, Uysal 1999, Özdemir et al 2008, Hosseinzadeh et al 2009, Miryeganeh and Movafeghi 2009.

Allium subg. Melanocrommyum is the second largest subgenus of Allium (Amaryllidaceae) and encompasses several taxonomically difficult groups. One of these is comprised of A. stipitatum and allies referrable to a vague number of sections, subsections and species. We investigated the anatomical characters of the scape in 12 species of this complex and its allies representing four recognized sections, viz Compactoprason, Megaloprason, Procerallium and Pseudoprason, and evaluated their systematic importance. The following features were found to be most informative for taxonomic classification of the complex at sectional and subsectional level: number of vascular bundles and their conforming rings, diameter of scape (or the cross‐sections), diameter of parenchymatous pith, thickness of sclerenchymatous ring and thickness of parenchymatous cortex. Statistical analyses (Kruskal‐Wallis, Anova and principal factor analysis) of 23 examined characters allow appropriate circumscription of species and sections in this species complex. In general, the results corroborate the conclusions from previous anatomical, morphological and molecular studies and phylogenetic reconstructions, but a few species are suggested to be reallocated among the sections.

“…Currently, several new taxa have been recognized in this genus based on their morphology including seed macro- and micro-morphological characteristics and phylogenetic studies [ 29 , 33 ]. Some other characteristics that provide important taxonomic information in Allium for infrageneric groups are anatomy of bulb tunic, scape, and pollen morphology [ 29 , 34 , 35 , 36 ].…”

We studied seed macro- and micro-morphological characteristics of 48 Allium species (51 accessions) belonging to 24 sections and 7 subgenera. Our taxonomic sampling focused on the central Asian regions of Uzbekistan, Kyrgyzstan, and Mongolia. The seed length ranged between 1.74 ± 0.16–4.47 ± 0.43 mm and width ranged between 1.06 ± 0.08–3.44 ± 0.23 mm, showing various shapes. The irregular and elongated polygonal testa cells occurred in all investigated species. Seed testa sculptures showed high variation in their anticlinal walls associated with different shapes: straight to with U-, S- or Omega-type undulations among the species. The moderately flat to convex periclinal walls with various sized verrucae or granules were found in all investigated taxa. Based on our research, we conclude that seed characteristics such as size, shape, and the seed testa features show their significant variability, revealing key characteristics to support taxonomic relationships and major clades recovered in the molecular phylogeny of the genus Allium. Especially, the anticlinal wall characteristics were highly variable and decisive at the both section and species levels. In addition, widely varied shapes and sizes of the seeds were remarkably effective to distinguish Allium species.

Taxonomically, Allium subg. Melanocrommyum (Webb & Berth.) Rouy is a controversial group with about 76 Iranian species and subspecies of the total taxanumber of 140-170 spp. Also, the subgenus encompasses A. Stipitatum Regel complex with vague borders at various taxonomic levels (Khorasani et al., 2018a). Allium stipitatum group consists of plants with basal leaves, inflorescence a dense umbel rich in flowers, long pedicles, pink to purple-violet flowers distributed mainly over western parts of Iran (Khorasani et al., 2018a). The earlier taxonomical works by Wendelbo (1971) placed the members of this group in two sections, A. sect. Megaloprason Wendelbo, including A. stipitatum Regel, A. altissimum Regel, A. chelotum Wendelbo, A. giganteum Regel, A. jesdianum Boiss. & Buhse, A. sarawschanicum Regel, and A. sect. Regeloprason Wendelbo, including A. bakhtiaricum Regel, based on size and shape of tepals and scape. The subsequent studies on members of complex recorded new taxa and revised the systematic position of some species (
