In Iran, Iraq, Turkey and adjacent southern parts of the U.S.S.R., four species of the genus
Vicia, group of
V. ciceroidea, occur, namely
V. multijuga (
Boiss.)
Rech. f.,
V. ciceroidea
Boiss.,
V. rafigae
Tamamšjan and the new species
V. sojakii described here. This group of species is distinguished by its tendency to reduction of leaflets, broadening of leaf rhachis
and dense branching of stems. With respect to these particular properties it is now convenient to esparate these species as
a series
Ciceroideae in the section
Cracca.
