Key to Frangula

A genus of ca. 50 species, shrubs and small trees, of the northern hemisphere. The distinctions between Frangula and Rhamnus s.l. are many and meaningful; their separation at the generic level seems warranted based on morphological and molecular analyses (Richardson et al. 2000a; Bolmgren & Oxelman 2004; Hauenschild et al. 2016a, 2016b).
