Saxifraga is the largest genus in the family Saxifragaceae, containing about 440 species of holarctic perennial plants, known as saxifrages or rockfoils. The Latin word saxifraga means literally "stone-breaker", from Latin saxum + frangere. It is usually thought to indicate a medicinal use for treatment of urinary calculi, rather than breaking rocks apart.
Micranthes hieraciifolia is a species of flowering plants. It is native to Europe, North America and temperate Asia, being distributed throughout the high Arctic and some alpine areas like Norway and the Carpathian Mountains, with a few isolated populations in the Central Eastern Alps of Austria and the Massif Central of France. It is generally uncommon.
Saxifraga cespitosa, the tufted alpine saxifrage or tufted saxifrage, is a flower common to many arctic heights. It appears further south in mountainous areas of the Alps, Norway, Scotland, Wales, Iceland, Siberia, western North America and Greenland.
MacGillivray's warbler is a species of New World warbler. These birds are sluggish and heavy warblers, preferring to spend most of their time on, or near the ground, except when singing.
William Fraser Tolmie was a surgeon, fur trader, scientist, and politician.
Saxifraga paniculata is an alpine species of flowering plant in the saxifrage family, with native distribution in the temperate northern hemisphere. Common names include alpine saxifrage, encrusted saxifrage, lifelong saxifrage, lime-encrusted saxifrage, livelong saxifrage, white mountain saxifrage, and silver saxifrage.
Micranthes nivalis is a plant species in the saxifrage family. It is commonly called snow saxifrage or (ambiguously) alpine saxifrage.
Calochortus tolmiei is a North American species of flowering plant in the lily family known by the common names Tolmie's star-tulip and pussy ears. It was discovered by and named for Dr. William Fraser Tolmie.
Micranthes aprica is a species of flowering plant known by the common name Sierra saxifrage. It is native to the high mountains of California, including the Sierra Nevada and the southern Cascade Range, and adjacent slopes in southern Oregon and western Nevada. It grows in mountain habitat in areas of alpine climate, such as meadows and next to streams of snowmelt. It is a perennial herb which spends most of the year in a dormant state in order to save water, and rarely flowers. It produces a small gray-green basal rosette of toothed oval leaves up to about 4 centimeters long. When it does bloom, it sends up an erect inflorescence on a peduncle several centimeters tall topped with a cluster of flowers. Each flower has five sepals, five small white petals, and a clump of whiskery stamens at the center.
Micranthes ferruginea is a species of flowering plant known by the common names russethair saxifrage and rusty saxifrage. It is native to western North America from Alaska and northwestern Canada to northern California to Wyoming, where it can be found in moist, rocky habitat in mountainous areas. It is a perennial herb growing from a caudex and rhizome system and producing a basal rosette of leaves. Each leaf is up to 6 centimeters long, thick and fleshy with large teeth along the edges. The inflorescence arises on a slender, hairy peduncle up to 40 centimeters tall. Thin branches bear flowers and reproductive bulbils. Each flower has spade-shaped white petals, the upper ones dotted with gold.
Micranthes howellii is a species of saxifrage known by the common name Howell's saxifrage. It is endemic to the Klamath Mountains of southern Oregon and northern California, where it grows in moist, rocky habitat. It is a perennial herb growing from a caudex, usually with a rhizome system. It produces a basal rosette of leaves with rounded or oval blades edged with dull or sharp teeth or scalloping. Each leaf is up to 6 centimeters long, thick and fleshy, and borne on a short petiole. The inflorescence arises on an erect peduncle up to 20 centimeters tall. An array of branches bear several flowers with small white petals.
Saxifraga aspera is a species of saxifrage known by the common name of rough saxifrage. In German it is known as Rauhhaariger Steinbrech. It is placed in section Trachyphyllum of the genus Saxifraga. There are two subspecies, Saxifraga aspera subsp. aspera and Saxifraga aspera subsp. micrantha. It is a plant of the pan-Arctic tundra and is also found in Europe at moderately high altitudes in the Alps, Pyrenees and northern Apennines.
Saxifraga bryoides is a species of saxifrage known by the common name of mossy saxifrage. In German it is known as Moosartiger Steinbrech. It is an inhabitant of the Arctic tundra but it also grows in the Alps and other European mountain ranges at high altitudes.
Micranthes is a genus of flowering plants in the saxifrage family. It was formerly included within the genus Saxifraga until recent DNA evidence showed the members of what is now Micranthes are more closely related to Boykinia and Heuchera than to other members of the genus Saxifraga.
Allium tolmiei is a plant species native to Idaho, eastern and central Oregon, southeastern Washington, northwestern Nevada and northeastern California. It occurs on mountains and scrublands at elevations of 1,300–9,200 feet (400–2,800 m). It was discovered by and named for Dr. William Fraser Tolmie.
Burroughs Mountain is located on the northeast slope of Mount Rainier above Glacier Basin. It was named for John Burroughs, the naturalist, who visited the mountain several times. The mountain was first called John Burroughs Mountain. Burroughs was born near Roxbury, New York, in April 1837, and died in 1931. He wrote extensively about his travels and was associated with the conservation movement. He became a well known "character" and is best remembered for his "Nature Essay."
Saxifraga rosacea, or Irish saxifrage, is a herbaceous plant in the family Saxifragaceae.
Saxifraga crustata, the crusted-leaved saxifraga and silver saxifrage, as well as encrusted saxifrage, is an evergreen perennial plant species in the family Saxifragaceae, native to the Eastern Alps. This species was described by Austrian botanist Lorenz Chrysanth von Vest in 1804.
