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.
