Allium therinanthum (Amaryllidaceae), a new species from Israel

2014

Allium therinanthum, a new species of A. sect. Codonoprasum, is described and illustrated from southern Mt. Hermon (Israel). It is a late-flowering diploid species (2n = 16), growing on calcareous substrates of the mountain belt. It is a narrowly distributed geophyte, showing morphological relationships mainly with A. tardiflorum, a typical autumnal species also occurring in Israel within the pinewoods of Mt. Carmel. The morphology, karyology, leaf anatomy, ecology, conservation status and taxonomical relations are examined for both species. A taxonomic comparison with the most allied late flowering species of the sect. Codonoprasum is provided.

A new autumn-flowering species of Allium (Alliaceae) from Croatia

2009

Here we describe Allium telmatum Bogdanovic, Brullo, Giusso & Salmeri, a new species of Allium sect. Codonoprasum from North Dalmatia (Croatia). Its chromosome number (2n = 32), karyotype, leaf anatomy, ecology and taxonomical relationships are examined. Several features, such as phenology (flowering in autumn), occurrence in coastal salt marshes, tetraploid chromosome number, and morphology, indicate that it is most closely related to the Tyrrhenian species Allium savii. On the basis of our herbarium survey, we present here a distribution map of the autumn-flowering species of Allium sect. Codonoprasum in the Mediterranean area.

Allium sphaeronixum (Amaryllidaceae), A New Species from Turkey

2023

In this paper, Allium sphaeronixum, a new species of the sect. Codonoprasum from Turkey, is described and illustrated. The new species is endemic to Central Anatolia, limited to the area of Nevşehir, where it grows on sandy or rocky soil at an elevation of 1000–1300 m a.s.l. Its morphology, phenology, karyology, leaf anatomy, seed testa micromorphology, chorology, and conservation status are examined in detail. The taxonomic relationships with the closest allied species, A. staticiforme and A. myrianthum, are also highlighted and discussed.

Cytotaxonomical investigation on Allium paniculatum ssp. exaltatum (Alliaceae) from Cyprus.

2004

Arare Allium endemic to Cyprus island, known as A. paniculatum subsp. exaltatum, is here examined. Relevant features in its morphology, caryology and leaf anatomy emphasize the marked taxonomic isolation of this taxon and allow it to be treated as a distinct species, proposed as Allium exaltatum. It is an exaploid plant (2n=48), probably arisen out of allopolyploidy and morphologically related only to some Middle East taxa.
