Cytotaxonomic investigations on Allium valdecallosum (Amaryllidaceae), a critical species endemic to Morocco

Abstract

Allium valdecallosum is a critical and poorly known species endemic to Morocco. Its diagnostic features, karyology, seed testa micro‐morphology, leaf anatomy, ecology, distribution, conservation status, and taxonomic relationships are examined here.

Allium albanicum (Amaryllidaceae), a new species from Balkans and its relationships with A. meteoricum Heldr. & Hausskn. ex Halácsy

“…As emphasised by numerous authors (Pastor 1981, Češmedžiev and Terzijski 1997, Fritsch et al 2006a, Neshati and Fritsch 2009, Celep et al 2012, Salmeri et al 2016, Lin and Tan 2017, Özhatay et al 2018, Brullo et al 2018), the micro-sculptures of the seed testa in the Allium species represent a very stable and conservative character, showing usually relevant taxonomical and phylogenetical implications. Seeds of A.albanicum at low magnification (30×) showed a semi-ovoid shape (3.5–4.0 × 2.4–2.5 mm), with a rather rugose surface (Fig.…”

“…Based on literature (Stearn 1978, 1980, Tzanoudakis 1983, Tzanoudakis and Vosa 1988, Brullo et al 2001), A.meteoricum was included in the sect. Scorodon Koch, but as highlighted by Brullo et al (2018), this traditional section is actually an assemblage of various and well-differentiated phylogenetic lineages (see Fritsch and Friesen 2002, Friesen et al 2006, Nguyen et al 2008, Hirschegger et al 2010, Li et al 2010).…”

“…Based on current knowledge (Stearn 1978, 1980, Brullo and Pavone 1983, Pastor and Valdes 1983, Brullo and Tzanoudakis 1989, Tzanoudakis and Kollmann 1991, Brullo et al 1992a, 1992b, 1993, 1994, 2018, Trigas and Tzanoudakis 2000, Khedim et al 2016), the following species, all having a Mediterranean distribution, can be included in this new section, in addition to A.meteoricum and A.albanicum : A.chalkii Tzanoud. & Kollmann, A.chrysonemum Stearn, A.erythraeum Griseb., A.franciniae Brullo & Pavone, A.grosii Font Quer, A.lagarophyllum Brullo, Pavone & Tzanoud., A.maniaticum Brullo & Tzanoud., A.obtusiflorum DC., A.reconditum Pastor, Valdes & Munoz, A.rhodiacum Brullo, Pavone & Salmeri, A.rouyi G. Gautier, A.runemarkii Trigas & Tzanoud., A.seirotrichum Ducellier & Maire, A.thessalicum Brullo, Pavone, Salmeri & Tzanoud., A.trichocnemis Gay and A.valdecallosum Maire & Weiller.…”

“…In the context of cytotaxonomical research on the genus Allium in the Mediterranean territories, especially regarding the subgen. Allium (Bogdanović et al 2008, 2009, 2011a, 2011b, Brullo et al 1997a, 1997b, 1999, 2001, 2003a, 2003b, 2004, 2007, 2008a, 2008b, 2009, 2010, 2014, 2017, 2018, Özhatay et al 2018), a peculiar population occurring in Albania, previously attributed to A.meteoricum Heldr. & Hausskn.…”

Allium shinasii (Amaryllidaceae), a new species from Turkey

“…is actually a combination of diverse phylogenetic lineages. Based on these studies, many taxa that were previously included in this section have been transferred to other sections (Friesen et al 2006, Hirschegger et al 2010, Li et al 2010, Brullo et al 2018).…”
