Chromosome numbers in astragalus and oxytropis with a discussion on the phylogeny of these genera
Most biologists agree that taxonomy should reflect phylogeny. In this thesis an attempt has been made to test the reliability of the chromosome number as a morphological character for the separation of species and genera in the legume family. Chromosome numbers have then been linked with geographic...

| Summary: | Most biologists agree that taxonomy should reflect phylogeny. In this thesis an attempt has been made to test the reliability of the chromosome number as a morphological character for the separation of species and genera in the legume family. Chromosome numbers have then been linked with geographic distribution in an attempt to determine the phylogeny of two genera, <u>Astragalus</u> and <u>Oxytropis</u>. |
