Seeds from O. lamarckiana were sown in the garden in large numbers. Some of these seeds developed forms exactly like those new ones found in the field. After several years of study and experimentation several distinct mutants of O. lamarck- iana were obtained in pure culture in the garden, which were new forms or elementary species as they are called.
