| Abstract: | Plants of Astranthium integrifolium (Michx.) Nutt. from Oklahoma proved to have a large B-chromosome which was morphologically similar to the smaller A-chromosomes. It was eliminated from some of the progeny of selfed plants. Structural modifications in the B-chromosome were observed. These observations are compared with ones obtained by previous workers, both for this species and in other genera. |
