Vandellis saxifrage ( Saxifraga vandellii ) is a species in the genus saxifrage ( Saxifraga ) in the family Saxifragaceae (Saxifragaceae). The species takes its name from its discoverer, the Italian naturalist Domenico Vandelli (1735-1816), who found it in Canzo near Lake Como. The plant was named by Kaspar Maria von Sternberg (1761-1838), an important Bohemian botanist, theologian, politician and mineralogist. He is considered to be the founder of paleobotany, but has also written a fundamental work on the saxifrage species.
