  abstract = {#{P}ennisetum$ sect. #{B}revivalvula$ is a species complex characterized by polyploidy and apoximis. {P}loidy level was assessed by {DAPI}-flow cytometry for 304 plants of the section, originating from {B}urkina {F}aso, {B}enin and southern {N}iger. {T}he results were confirmed for 54 plants based on chromosome counts. {T}he samples show four euploidy levels (with x = 9) distributed among five species : #{P}. hordeoides$ (2n = 36, 54), #{P}. pedicellatum$ (2n = 36, 45, 54), #{P}. polystachion$ (2n = 18, 36, 45, 54), #{P}. setosum$ (2n = 54), and #{P}. subangustum$ (2n = 18, 36, 54). {T}he geographical distribution of these ploidy levels seems related to major vegetation zones present in {A}frica. {D}iploid populations of #{P}. polystachion$ and #{P}. subangustum$ were found in the {B}anfora area, in {B}urkina {F}aso.
