Narrative

Saxifrage Family (Saxifragaceae) contains herbs, bushes, and trees found throughout the world. There are about 650 to 1200 species in this family. There is controversy over the limits of this family as various authors define it differently. For example, the Hydrangea and Philadelphus group is frequently given separate family status in the Hydrangeaceae family. The Ribes group is also frequently given family status in the Grossulariaceae family. Kartesz shows 174 species in the Saxifrage family; another 52 species in the Hydrangea family, and another 57 species in the Grossulariaceae family growing in greater North America.)
