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.
Analisi preliminare dello stato di conservazione in situ ed ex situ di 28 specie prioritarie di Allium L. in Italia
2020
Partendo da una checklist aggiornata delle Crop Wild Relatives presenti in Italia, si sono così selezionati i taxa a più alta priorità di conservazione del genere Allium L. (pari a 28 taxa endemici e/o inseriti nelle più recenti Liste Rosse). Si è proceduto alla determinazione della loro distribuzione sulla base di database online, fonti di erbario e bibliografiche per le quali si è effettuato il relativo georeferenziamento. Per gli scopi del presente studio, una volta riportati su mappa i punti corrispondenti alle località di rinvenimento dei taxa oggetto d’analisi, si è poi sovrapposto un layer contenente tutte le aree protette presenti sul territorio (Riserve, Parchi, siti Natura2000, ec…
Allium garganicum (Alliaceae), a new species from Apulia (SE Italy)
2009
Abstract A new endemic species of Allium, belonging to the A. stamineum Boiss. group, is described from the Mount Gargano (Apulia, SE Italy). This new taxon, named Allium garganicum, is the single representative of this group in the Italian flora, limited to a small population growing on the limestone rocks near the coast. Its relationships with allied taxa, A. stamineum Boiss. and A. guicciardii Heldr., are also discussed.
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.
