Saxifragaceae genera

Saxifraga is the largest genus in the family Saxifragaceae, containing about 473 species of holarctic perennial plants, known as saxifrages or rockfoils. The Latin word saxifraga means literally "stone-breaker", from Latin ' ("rock" or "stone") + ' ("to break"). It is usually thought to indicate a medicinal use for treatment of urinary calculi (known as kidney or bladder stones), rather than breaking rocks apart.

thumb|Bergenia sp. Bergenia (elephant-eared saxifrage, '''elephant's ears''') is a genus of ten species of flowering plants in the family Saxifragaceae, native to central Asia, from Afghanistan to China and the Himalayan region.

Chrysosplenium (golden saxifrage or golden-saxifrage) is a genus of flowering plants in the family Saxifragaceae. It includes 84 species found throughout the Arctic and northern temperate parts of the Northern Hemisphere. The highest species diversity is in eastern Asia, and some species are found disjunctly in South America.

Astilbe is a genus of 18 species of rhizomatous flowering plants within the family Saxifragaceae, native to mountain ravines and woodlands in Asia and North America. Some species are known by the common names '''false goat's beard and false spirea'''.

Heuchera ( or ) is a genus of largely evergreen perennial plants in the family Saxifragaceae. All species are native to North America except for Heuchera sichotensis, native to the Russian Far East. Common names include alumroot and coral bells.

Tiarella, the foamflowers, is a genus of flowering plants in the family Saxifragaceae. The generic name Tiarella means "little turban", which suggests the shape of the seed capsules. Worldwide there are seven species, one each in eastern Asia and western North America, plus five species in eastern North America. , the taxonomy of Tiarella in eastern North America is in flux.

Mitella is a genus of flowering plants known as miterworts or '''bishop's caps'. Mitella'' species are native to temperate and arctic North America and Asia.

Micranthes is a genus of flowering plants in the saxifrage family. It was formerly included within the genus Saxifraga until DNA evidence from 1996 showed the members of what is now Micranthes are more closely related to Boykinia and Heuchera than to other members of the genus Saxifraga.

Boykinia is a small genus of plants related to the saxifrages. It contains at least nine species, known as brookfoams. Brookfoams are glandular rhizomatous creeping perennials with highly lobed or toothed leaves and inflorescences of petite flowers. They are native to North America (the west coast from Alaska to Baja California and the southeastern United States) and Asia (Japan).

Lithophragma is a genus of flowering plants in the saxifrage family containing about nine species native to western North America. These plants are known generally as woodland stars. The petals of the flowers are usually bright white with deep, long lobes or teeth. Each petal may look like three to five petals, when at closer inspection the lobes fuse into a single petal at its base. Most species reproduce via bulblets instead of seeds. L. maximum is a federally listed endangered species. Lithophragma specifically coevolved with moths of the genus Greya, who pollinate and only lay eggs on Lith

Tolmiea is a genus of flowering plants in the saxifrage family containing two species native to northwestern North America. The genus was formerly considered to be monotypic until diploid populations were split off as T. diplomenziesii from the tetraploid populations of T. menziesii.

Jepsonia is a small genus of flowering plants containing three species. The Jepsonia is a perennial with a cormlike caudex, toothed leaves, and a cyme inflorescence that blooms in the fall. Jepsonia plants are native to California and Baja California.

Bolandra is a small genus of plants related to the saxifrages. It contains two species known as false coolworts. These are perennials with toothed leaves and inflorescences of curling, sharp-petalled flowers. They are both native to western North America.

Sullivantia, commonly called coolwort, is a genus of flowering plants in the saxifrage family. It is a small genus, comprising only 3-4 species of perennial herbs all native to the northwestern and east-central United States. Sullivantia is most notable for having disjunct distributions primarily restricted to along the Pleistocene glacial margin. All species of Sullivantia are found on moist, often calcareous cliffs.

Peltoboykinia is a genus of flowering plants belonging to the family Saxifragaceae.

Suksdorfia is a genus in the family Saxifragaceae. It has only two accepted species, Suksdorfia alchemilloides and Suksdorfia violacea, native to central South America and northwestern North America, respectively. Asa Gray named the genus Suksdorfia after Wilhelm Nikolaus Suksdorf, a mostly self-taught German botanist who came to the United States at age eight and found the species S. violacea in the northwestern United States. S. violacea is the type species for this genus.
