Genus Onobrychis (Fabaceae) in Tunisia: distribution, rediscovery, ecology, and description of two new variety with an updated identification key in the country

Abstract

Long-term field surveys within Tunisian dorsal revealed the recollection of the poorly known North African endemic Onobrychis kabylica and O. conferta subsp. conferta. Two new varieties of O. conferta subsp. conferta are described and illustrated, a key to recognize the two varieties of the species and a distribution map of both taxa are included. IUCN Red List assessment shows that the species should be considered Critically Endangered and requires the implementation of immediate appropriate measurements to ensure their conservation.
