The present study reports the chromosome number and meiotic behavior including microsporogenesis of Actaea kashmiriana J. Compton and its relation with pollen fertility and seed set. The species showed a chromosome count of 2n=4x=32 and meiotic chromosomal irregularities such as chromatin stickiness, cytomixis, laggard formation, chromosomal bridges, micronuclei and polysporads. B-chromosomes were also observed in this species. Due to these meiotic irregularities, reduced pollen fertility was observed in the range of 85–87%, and the seed set was also significantly reduced to 67.16 to 70.45%.
