Phylogenetic status of Vavilovia formosa (Fabaceae-Fabeae) based on nrDNA ITS and cpDNA sequences

The phylogenetic status of the monotypic genus Vavilovia was studied using nrDNA ITS and cpDNA trnL-F and trnS-G regions. The results from the analysis of each dataset and the combined dataset, revealed that Vavilovia is closely related to Pisum, forming a group that is sister to Lathyrus. The molecular data and some morphological and biological characteristics strongly indicate that Vavilovia should be subsumed under Pisum, as Pisum formosum.
