Kingdom Phylum Class Order Family
PLANTAE TRACHEOPHYTA LILIOPSIDA LILIALES ALLIACEAE

Scientific Name: Allium acutiflorum
Species Authority: Loisel.
Taxonomic Notes: Allium acutiflorum Loisel. is a tertiary wild relative of a number of crops in the allium group, including onion (A. cepa L.), Welsh onion (A. fistulosum L.), leek (A. porrum L.), garlic (A. sativum L.) and chives (A. schoenoprasum L.).

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2013
Date Assessed: 2010-04-15
Assessor(s): Draper, D., Branca, F. & Donnini, D.
Reviewer(s): Nieto, A. & Kell, S.P.
Contributor(s): Kell, S.P.
Justification:

The population of Allium acutiflorum is fragmented and the subpopulation in Italy is small. However, in Italy the population is stable and in France it occurs in six departments in the south and southeast, as well as in the northern and southern departments of Corsica. On this basis, it is assessed as Least Concern. However, a re-evaluation of this species is recommended once information about the subpopulations in mainland France and Corsica is available. Germplasm collection and duplicated ex situ storage is a priority for this species.


Geographic Range [top]

Range Description: A. acutiflorum is native to south France, Corsica and northwest Italy (Mathew 1996). In France this species occurs in the south and southeastern departments of Aude, Pyrénées Orientales, Bouches-du-Rhône, Var, Alpes-de-Haute-Provence, Alpes-Maritimes, as well as in Haute-Corse and Corse-du-Sud (Association Tela Botanica 2000–2010). In Italy it is present in Liguria and there are unconfirmed occurrences in Piamonte. It has been cited as occurring in Spain but this is erroneous.

Population [top]

Population: In Italy the subpopulation is small but it is believed to be stable. It is extremely isolated from the main subpopulation and it is rare.
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: It grows mainly at low altitudes near the sea in sandy and rocky places and flowers May–June (Mathew 1996).
Systems: Terrestrial

Use and Trade [top]

Use and Trade: It is a tertiary wild relative of and potential gene donor to a number of crops in the allium group, including onion (A. cepa), Welsh onion (A. fistulosum), leek (A. porrum), garlic (A. sativum) and chives (A. schoenoprasum).

Threats [top]

Major Threat(s): The threats to this species are unknown; however, the population is vulnerable due to being severely fragmented.

Conservation Actions [top]

Conservation Actions: In Liguria it is protected by law and it occurs in at least one protected area. It is considered Low Risk in Piemonte.

No germplasm accessions of A. acutiflorum are reported by EURISCO to be held in European genebanks (EURISCO Catalogue 2010). Germplasm collection and duplicated ex situ storage is a priority for this species.
