Saxifragaceae.—A moderately high, strict clumpy shrub 3 to 6 feet tall; the bark on old stems shreddy; branchlets pubescent; leaves ovate to orbicular, acuminate, usual- ly cordate, opposite, 2 to 6 inches long, serrate; flowers small, greenish-white, very numerous in terminal, cymelike clus- ters, among them a number of conspicuous sterile flowers with large, white sepals; fruit a tiny, many-seeded capsule. The roots collected in the fall. When dry, the root is very tough; it should be cut in short pieces before drying.

Used as a diaphoret- ic and diuretic. [^Hydrangca cinerea Small, ashy hydran- gea, is a smaller shrub with leaves tomen- tose on the underside.
