SAXIFRAGA, in botany, a genus of the decandria digynia class. The calix consists of five segments, and the corolla of five petals; the capsule has a double beak and one cell. The species are 38, nine of them natives of Britain.
The tuberosities at the root of the granulata or white-flowered saxifrage are kept in the shops, under the name of saxifrage seeds; they are diuretic and attenuant; and therefore good in nephritic cases and obstructions of the menes and viscera.
