Allium nazarenum (Amaryllidaceae), a new species of the section Codonoprasum from Israel

2017

Allium nazarenum, a new species of A. sect. Codonoprasum, is described and illustrated from Israel. Within this species, two well distinct subspecies have been recognized, represented by the subsp. nazarenum and subsp. ramonense respectively. The first one occurs in northern and central Israel, which falls within the Mediterranean bioclimate, while the second one is circumscribed to the Negev desert. Both taxa are diploid with 2n = 16 and are found on various substrata usually in the batha or steppic plant communities. This species shows close relationships with the species belonging to the A. staticiforme group, from which it differs in several relevant diacritic features. Its morphology, …

Allium achaium Boiss. & Orph. ex Boiss. (Alliaceae), a critical species of Greek flora

2011

Allium achaium Boiss. & Orph. ex Boiss. (Alliaceae), a critical and misappreciated species of Greek flora is investigated from taxonomic point of view and illustrated. It belongs to A. sect. Codonoprasum and shows close relationships with the taxa of the A. stamineum Boiss group. Besides, its karyology, ecology and distribution are examined.

Allium makrianum (Alliaceae), a new autumnal species from Greece

2010

Allium makrianum is described as a new species growing on the limestone of the Chios, north-eastern Aegean island (Greece). It is a very rare autumnal geophyte, showing some relationship with A. archeotrichon from Rhodos. Its iconography, morphology, chromosome number (2n=16), leaf anatomy, ecology and taxonomy are examined.

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

2019

A new species, Alliumalbanicum, is described and illustrated from Albania (Balkan Peninsula). It grows on serpentines or limestone in open rocky stands with a scattered distribution, mainly in mountain locations. Previously, the populations of this geophyte were attributed to A.meteoricum Heldr. & Hausskn. ex Halácsy, described from a few localities of North and Central Greece. These two species indeed show close relationships, chiefly regarding some features of the spathe valves, inflorescence and floral parts. They also share the same diploid chromosome number 2n =16 and similar karyotype, while seed testa micro-sculptures and leaf anatomy reveal remarkable differences. There are …

Allium cithaeronis (Alliaceae), a new species of A. sect. Scorodon from Greece.

2011

Allium cithaeronis, a new species of A. sect. Scorodon from Greece is described and illustrated. Its chromosome number (2n=16), karyogram, leaf anatomy, ecology, taxonomical relationship are examined. For some morphological features, such as exerted stamens from perigon and tuberculate lobes in the upper part of the ovary,it represents a very isolated species within the A. sect. Scorodon.

Biosystematic researches on Allium cupani group (Amaryllidaceae) in the Mediterranean area.

2015

Allium cupani Raf. is a species complex of the subgenus Allium L., which is taxonomically quite critical mainly for its marked karyological and morphological variability. In the present study, karyo-taxonomic characterization of some peculiar populations of this group from Italian, N African, Balcan and Aegean territories has been performed, using both living plants collected in the field and herbarium material. As a result, ten new species have been recognized and described within the A. cupani complex. They are A. panormitanum from N Sicily, A. samniticum from C Italy, A. mauritanicum from N Morocco and NW Algeria, A. balcanicum from mountains of Balkan Peninsula, A. tzanoudakisanum from …
