Abstract Various species ofTaxodiaceae were selected for chromosome studies to indicate cytotaxonomic and phylogenetic relationships. Point dispersal patterns of diagrammatic presentations of the species' karyotypes, rather than marker chromosomes, were found to be the most significant cytotaxonomic characteristic in indicating phylogenetic relationships. Karyotypic evolution inTaxodiaceae appears to occur by unequal reciprocal translocations followed by pericentric and paracentric inversions. Cytotaxonomic relationships among species generally correspond to the phylogenetic relationships withinTaxodiaceae indicated by classical taxonomic classification. Presence and types of marker chromosomes may have the potential to indicate relationships between different coniferous families.
