Allium rouyi


Taxonomy [top]

Kingdom Phylum Class Order Family

Scientific Name: Allium rouyi
Species Authority: Gaut.
Common Name(s):
Spanish Ajo Amarillo
Allium chrysonemum Stearn
Allium reconditum Pastor, Valdés & Muñoz
Taxonomic Notes: Allium rouyi Gaut. 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.). Spanish experts present at a European crop wild relative Red List workshop convened in April 2010 consider A. chrysonemum to be a synonym of A. rouyi; however, both species are recognized and accepted by Euro+Med PlantBase (2006) and Govaerts et al. (2005–2007).

Although A. chrysonemum and A. rouyi are recognized and accepted by Cabezudo et al. (2004), Euro+Med PlantBase (2006) and Govaerts et al. (2005–2007), recent research has proved that A. chrysonemum Stearn and A. reconditum Pastor, Valdés & Muñoz are synonyms with A. rouyi, and therefore, distribution of this species extends throughout the south of the Iberian Peninsula (Pastor 2009, Aedo in prep.).
