Note For a taxonomic revision of the genera Berberis and Mahonia, both well endowed with American and Asian species, the reader is referred to the work of Ahrendt (in Jour. Linn. Soc. 57: 1. 1961) in which nearly 500 species of Berberis and about 100 species of Mahonia are recognized, although no Panama specimens of either genus are cited. Onlv one species of the often-cultivated genus Berberis, has been recorded from Panama.
