“…The octoploid level is rare and it seems known in two species only, Bellevalia longistyla (Miscz.) Grossheim, 1928 (Özhatay and Johnson 1996, Johnson 2003) and Bellevalia olivieri (Baker) Wendelbo, 1985 (Bareka et al 2012, 2015). Singular populations with 2n = 4x = 32 have been also quoted for Bellevalia glauca (Lindley) Kunth, 1843 and Bellevalia sarmatica (Pallas ex Miscz.)…”

“…Only B chromosomes were sometimes observed in diploids such as Bellevalia saviczii Woronow, 1927 with 2n = 8 + 1B (Gettner, 2005) and Bellevalia koyuncui Karabacak & Yildirim, 2015 with 2n = 8 + 2B (Karabacak et al 2015). The occurrence of aneuploidy in a polyploid context, associated with vegetative reproduction, may indicate chromosomal changes in process providing evolutionary potential, as presumed for B-chromosomes (Johnson 2003, Weiss-Schneeweiss and Schneeweiss 2013, Bareka et al 2015). The absence of structural differentiation and the total length of the octoploid complement, nearly twice that of the tetraploid (171.4 versus 93.05 µm), argue for an autopolyploidy event.…”

“…Polyploid species such as Bellevalia pseudolongipes Karabacak & Yildirim, 2014 (Karabacak et al 2014), Bellevalia clusiana Grisebach, 1844 (Yaylaci et al 2009) and Bellevalia edirnensis N.Özhatay & Mathew, 1991 (Özhatay et al 1991b) were identified as triploid, tetraploid and hexaploid respectively. Recently, a new hexaploid species, Bellevalia juliana Bareka, Turland & Kamari, 2015 (Bareka et al 2015) was found in Greece. In Tunisia, two tetraploid endemic species were described, Bellevalia galitensis Bocchieri & Mossa, 1991 and Bellevalia dolichophylla Brullo & Minissale, 1997 (Bocchieri and Mossa 1991, Brullo and Minissale 1997).…”

Karyological investigations were carried out on four species of Bellevalia Lapeyrouse, 1808 and Muscari Miller, 1758 (Asparagaceae) sampled in contrasting bioclimatic conditions of Algeria. The endemic Bellevalia mauritanica Pomel, 1874 was found to have a tetraploid cytotype 2n = 4x = 16 and an octoploid 2n = 8x = 32 which is a new report. The chromosome number 2n = 2x = 18 in Muscari comosum (Linnaeus, 1753) Miller, 1768 and Muscari maritimum Desfontaines, 1798 was in conformity with earlier reports. The latter species reveals a lesser bimodality of the karyotype. Within Muscari neglectum Gussone ex Tenore, 1842 pentaploid (2n = 5x = 45), hexaploid (2n = 6x = 54) and very rare octoploid cytotype (2n = 8x = 72) have been reported in Algeria. Principal component analysis performed on basis of karyotype parameters, showed a segregation of the different cytotypes. This study provides new karyological information, which is discussed in a taxonomic context.

In the south-central Mediterranean four tetraploid species of Bellevalia occur: B. dolichophylla, B. galitensis, B. mauritanica, and B. pelagica. Another group of plants, morphologically similar to B. dolichophylla, has been recently recovered in Zembra Island (Tunisia). A phylogenetic reconstruction involving all these tetraploid taxa was performed using both plastidial and nuclear markers (trnL-trnF and ITS, respectively). For all these taxa, an allopolyploid origin involving B. romana and B. dubia is supported. Regarding plants from Zembra, they may fall within the variability of B. dolichophylla

A revised infrageneric classification of Bellevalia Lapeyr. (Asparagaceae: Scilloideae) based on molecular analysis

Within the genus Bellevalia (Asparagaceae: Scilloideae: Hyacintheae), flower shape and colour, the ratio of leaf to scape length, and the orientation of the pedicels were traditionally used to delimit sections, subsections and species. We conducted a phylogenetic analysis of representative species from sections Bellevalia, Conicae, Nutantes and Oxydontae, representing four out of the six sections that are currently recognised, using the four chloroplast regions rbcL, matK, trnL intron, and trnL-F spacer. Our results indicate that the sections are not monophyletic as currently circumscribed. Our analyses retrieve two major, well-supported clades. The first clade (sect. Conicae) includes only species with ciliate leaves and green-veined perianth lobes, and the second clade (sect. Bellevalia) includes the species lacking these characteristics. Within the second clade, the species with yellow anthers are separated from those with violet anthers. Our molecular analysis does not support the traditional subdivisions of the genus but establishes the value of cilia on the leaf margin, green veins in the perianths lobes, and the colour of the anthers as indicators of relationships among the species. We recommend that the current four sections and six subsections of Bellevalia be reduced to two sections without subsections and we provide an updated and corrected nomenclature for these sections and subsections, designating lectotypes where necessary.
