Oxytropis birjandica (Fabaceae: Papilionoideae, Galegeae), a new species from Iran, South Khorassan Province

A new species of Oxytropis (Fabaceae), distinguished by its white petals, is described and illustrated here as Oxytropis birjandica sp. nov., an endemic to South Khorassan Province in eastern Iran. Morphological evidence suggests a close affinity with O. sutakensis Maassoumi and O. compacta Maassoumi & Joharchi. The species was discovered at a single locality, and no additional records have been reported since the original collection in ۱۹۹۶. Given its apparent rarity and highly restricted distribution, its conservation status is provisionally assessed as Critically Endangered (CR) following the IUCN Red List criteria. A detailed morphological description, diagnostic comparisons, photographs, habitat information, distribution map, and conservation assessments are provided.
