Summary An enigmatic, highly localized endemic of the Far‐Eastern USSR was first considered a species of Medicago , subsequently transferred to Trigonella , and most recently elevated to the monotypic genus Ursia Vass. Its affinities, however, are with Trifolium , particularly with T. eximium , but also with the only sympatric indigenous clover, T. lupinaster.
