Abstract:

Variation of 89 multistate morphological characters in 44 species of Vicia subgen. Cracca was investigated with cladistic and phenetic methods using Lathyrus sylvestris and Pisum elatius as outgroups. The subgenus appears monophyletic; the Ervum group is supported as a section. Sections Vicilla and Cassubicae appear monophyletic when V. amoena is moved to section Cassubicae. Placement of V. biennis in a separate section is supported, sections Variegatae and Panduratae are nested in section Cracca, and section Pedunculatae is not supported as monophyletic. Use of different outgroups results in slightly different substructures for sect. Cracca.
