Micranthes hieraciifolia (common names: hawkweed-leaved saxifrage, hawkweed-leaf saxifrage, stiff stem saxifrage or stiff-stemmed saxifrage) is a species of flowering plants. It is native to Europe, North America and temperate Asia, [1] 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.
It grows to a height of 10–20 cm. The leaves are oblong to rhombic, thick, and remotely toothed. The stem is single, stout and thick, and densely glandular. The flowers are produced in dense clusters, small and inconspicuous, with greenish to purplish petals.
It grows in meadows, on solifluction soil, and in places with well-developed moss.
Saxifraga is the largest genus in the family Saxifragaceae, containing about 465 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.
There are over 190 vascular plant species on the Norwegian Arctic archipelago of Svalbard. This figure does not include algae, mosses, and lichens, which are non-vascular plants. For an island so far north, this number of species constitutes an astonishing variety of plant life. Because of the harsh climate and the short growing season, all the plants are slow growing. They seldom grow higher than 10 cm (4 in)
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.
Micranthes stellaris, synonym Saxifraga stellaris, the starry saxifrage or hairy kidney-wort, is an Arctic–alpine species in the family Saxifragaceae. It produces panicles of 5–10 white flowers on a stem up to 20 cm (7.9 in) tall, rising from a basal leaf rosette. One subspecies is found from eastern Canada to Russia, including the British Isles, while another is found in the mountains of southern Europe.
Cwm Idwal is a cirque in the Glyderau range of mountains in northern Snowdonia, the national park in the mountainous region of North Wales. Its main interest is to hill walkers and rock climbers, but it is also of interest to geologists and naturalists, given its combination of altitude, aspect (north-facing) and terrain. In a 2005 poll conducted by Radio Times, Cwm Idwal was ranked the 7th greatest natural wonder in Britain.
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 virginiensis, the early saxifrage, or Virginia saxifrage, is a wildflower native to eastern and central North America.
Erechtites hieraciifolius is a plant in the daisy family, Asteraceae. It is native to the Americas, but is found many places around the world having been introduced by human activity. It is introduced in Hawaii, China, and Southeast Asia.
Micranthes nivalis is a plant species in the saxifrage family. It is commonly called snow saxifrage or (ambiguously) alpine saxifrage.
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.
Micranthes integrifolia is a species of flowering plant known by the common name wholeleaf saxifrage. It is native to western North America from British Columbia to Montana and northern California, where it grows in moist habitat, including meadows, prairies, and grassy mountain slopes. It is a perennial herb growing from a caudex and system of rhizomes, and producing a basal rosette of leaves. Each leaf is up to 7 centimeters long with a toothed or smooth-edged blade borne on a short petiole. The inflorescence arises on a stout, hairy peduncle up to 35 centimeters tall. White-petaled flowers occur in a cluster or dense array at the top.
Micranthes oregana is a species of flowering plant known by the common name Oregon saxifrage. It is native to western North America, including the mountainous regions of the western United States. It can be found in moist habitat, such as marshes and other wetlands. It is a perennial herb growing from a thick, fleshy or woody caudex. It produces a basal rosette of linear to lance-shaped leaves each up to 25 centimeters long. The inflorescence arises on a stout peduncle which may exceed a meter in height. It is topped with one or more dense clusters of white-petaled flowers.
Micranthes tolmiei is a species of flowering plant known by the common name Tolmie's saxifrage, or Tolmie's alpine saxifrage. It is native to western North America from Alaska to Montana to California, where it grows in rocky mountain habitat types, especially in alpine climates, such as talus and fellfields. It is a small perennial herb growing in mats of creeping stems lined with thick, fleshy leaves each up to 1.5 centimeters long. The inflorescence arises on a stout, erect peduncle with a few stubby bracts midway up. The flowers have narrow white petals and petal-like white stamens.
Micranthes micranthidifolia is a member of the Saxifrage family with the common names lettuceleaf saxifrage, branch lettuce and brook lettuce. It grows in wet areas and mountain streams.
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.
