Saxifraga is the largest genus in the family Saxifragaceae, containing about 440 species of holarctic perennial plants, known as saxifrages[2] or rockfoils.[3] The Latin word saxifraga means literally "stone-breaker", from Latin saxum ("rock" or "stone") + frangere ("to break"). It is usually thought to indicate a medicinal use for treatment of urinary calculi (known as kidney stones), rather than breaking rocks apart.[2][4]

The genera Saxifragopsis (strawberry saxifrage), and Saxifragella are sometimes included in Saxifraga.[1] In recent DNA based phylogenetic analyses of the Saxifragaceae, the former sections Micranthes and Merkianae are shown to be more closely related to the Boykinia and Heuchera clades,[5] and the most recent floras separate these groups as the genus Micranthes.[6][7]

Description

Round-leaved saxifrage (S. rotundifolia), whose sticky leaves seem to catch small invertebrates

Most saxifrages are smallish plants whose leaves grow close to the ground, often in a rosette. The leaves typically have a more or less incised margin; they may be succulent, needle-like and/or hairy, reducing evaporation.[8]

The inflorescence or single flower clusters rise above the main plant body on naked stalks. The small actinomorphic hermaphrodite flowers have five petals and sepals and are usually white, but red to yellow in some species.[citation needed] As in other primitive eudicots, some of the 5 or 10 stamens may appear petal-like.[citation needed] and it lives tundra ecosystem.
