Rhamnaceae, the
Buckthorn family, is a family of flowering
plants, mostly
shrubs and often
thornyy, some (e.g.
Paliurus spina-christi and
Colletia cruciata) spectacularly so. The family contains 55 genera and approximately 900 species. The Rhamnaceae have a worldwide distribution, but are more common in the subtropical and tropical regions. The earliest fossil evidence of Rhamnaceae is from the
Eocene.
Economic uses of the Rhamnaceae are chiefly as ornamental plants and as the source of many brilliant green and yellow dyes.
