The present study reports the chromosome number and meiotic behavior of 11 populations belonging to four species of Phlomoides (L.) Moench. All populations showed the diploid chromosome number 2 n = 2 x = 22; consistent with the proposed base number of x = 11. Almost all taxa studied here displayed regular bivalent pairing and chromosome segregation at meiosis. However, meiotic abnormalities observed included varied degree of fragmented chromosomes, laggards and bridge in anaphase I to telophase II, precocious division of centromeres, asynchronous nucleus and cytomixis. In addition, a survey on chromosome counts of different species belonging to the genus Phlomoides throughout the world is presented and the base chromosome numbers and polyploidy levels discussed here.
