Summary Claytonia virginica L. has two morphological races and some fifty chromosomal cytotypes. Even though apparently unique this complexity may prove to be of more general importance in the future. Simplicity and the most obvious may not always be Nature's way. In C. virginica growth and development, cytoecology and evolution are in juxtaposition, interacting and awaiting understanding. — The term biosystematics is now redundant because it has served its purpose to stress the importance of populational studies and cytogenetics for systematics.
