Berberis pinnata
Berberis haematocarpa
Subspecies 2 (2 in the flora).
Berberis pinnata is very similar to B. aquifolium, and the two are sometimes difficult to separate. Some authors have used the spacing of the lateral leaflets (said to be contiguous or imbricate in B. pinnata and remote in B. aquifolium) to separate them, but the leaflets are often remote in both species and may be contiguous in B. aquifolium.
Berberis pinnata is resistant to infection by Puccinia graminis.

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.
Berberis haematocarpa is susceptible to infection by Puccinia graminis.
