In section Dentati, the chromosome numbers were reported from only eight of 30 taxa. There is no chromosomal record relating to other 22 present study, it intended detect Dentati Chromosome 15 taxa obtained, 13 which for first time and two agreed with previous reports. 14 diploid 2x = one taxon was polyploid 4x 60. Polyploidy might have played a role in karyotype evolution genus. Although polyp...

BACKGROUND AND AIMS For 84 years, botanists have relied on calculating the highest common factor for series of haploid chromosome numbers to arrive at a so-called basic number, x. This was done without consistent (reproducible) reference to species relationships and frequencies of different numbers in a clade. Likelihood models that treat polyploidy, chromosome fusion and fission as events with...

Until now, basic karyological parameters have been used in different ways by researchers to infer karyological relationships among organisms. In the present study, we propose a standardized approach to this aim, integrating six different, not redundant, parameters in a multivariate PCoA analysis. These parameters are chromosome number, basic chromosome number, total haploid chromosome length, M...
