The Buckthorns (Rhamnus) are a genus (or two overal, if Frangula is handled as distinct) of about 100 types of plants or little trees and shrubs from 1-10 m high (rarely to 15 m), in the buckthorn household Rhamnaceae. They are ancient throughout the moderate and subtropical Southern Hemisphere, and also more in the area in the subtropical Lower Hemisphere in components of African-american and Southern The united states.
