Abstract
Tulipa clusiana is characterized by a highly variable phenotype. The species comprises var. chrysantha Sealy (2n=2x=24), var. stellata Regel (2n=3x=36; 2n=4x=48) and var. typica Regel (2n=2x=24; 2n=4x=48; 2n=5x=60). Several populations of these varieties were all found to exhibit remarkable uniformity in basic karyotype. A few plants had some structurally altered chromosomes otherwise unknown within the species and its allies. These chromosomes are suspected to be products of translocations. They are very long with almost median centromere. Occasional aneusomaty and polysomaty have also been observed in some plants. The evolutionary significance of these aberrations is discussed.
