Low fertility and vigor, and requirements of ecological niches distinct from diploids are not universal characteristics of autoploids. InClaytonia, Hedyotis, Oldenlandia, and other genera, occurrence and frequency of both polyploids and aneuploids within species populations suggest a greater role of such mutations in the evolution of vascular plants than heretofore presumed.
