Abstract
The genus Krigia Schreb. consists of 9 spp. representing diploid and polyploid taxa. Karyotype morphology and meiotic pairing of chromosomes for 5 spp. are described K. cespitosa (2n = 8) and K. biflora (2n = 10) are diploids. K. montana with 2n = 30 is a tetraploid. Diploid and tetraploid forms of K. virginica with 2n = 10 and 20 were also studied K. dandelion 2n = 60 is a high polyploid species.
