Abstract Intraspecific life‐history variations of Viola brevistipulata var. brevistipulata were examined with special reference to reproductive features based on quantitative and qualitative monitoring of chasmogamous ( CH ) and cleistogamous ( CL ) flowers. We selected 10 populations in southwestern Hokkaido in common deciduous forests, and marked 40–70 individual plants at each population. Marked individuals were monitored every 1–2 weeks. The expression of CH and CL flowers was distinct among the populations. That is, there were populations consisting of plants with only CH flowers, while other populations produced CL flowers after CH flowers with greater shoot longevity This phenomenon was observed even in populations located at the same site. The results suggest that V . brevistipulata var . brevistipulata shows distinct life‐history variations among the populations.
