Berberis fremontii
Berberis haematocarpa
Berberis fremontii is susceptible to infection by Puccinia graminis.
The Apache Indians used Berberis fremontii for ceremonial purposes; the Hopi used it medicinally to heal gums (D. E. Moermann 1986).

Typical populations of Berberis haematocarpa (with narrowly ovate or lanceolate leaflets and small, juicy, deep red berries) and B. fremontii (with ovate or orbiculate leaflets and large, dry, inflated, yellowish or brownish berries) are easily distinguished. These characteristics are not always well correlated, however, and intermediate populations, showing different combinations of leaflet shape and berry size, color, and inflation, are known.
