Micranthes rufidula is a species of flowering plant known by the common name rustyhair saxifrage. It is native to western North America from British Columbia to Oregon, and one location in northern California. It grows in moist, open and rocky habitat in mountainous areas. It is a perennial herb growing from a small caudex and system of rhizomes. The leaves have oval blades lined with blunt teeth borne on long petioles. The inflorescence arises on a hairy peduncle, the flowers bearing white petals.
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.
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.
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)
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.
An Arctic–alpine taxon is one whose natural distribution includes the Arctic and more southerly mountain ranges, particularly the Alps. The presence of identical or similar taxa in both the tundra of the far north, and high mountain ranges much further south is testament to the similar environmental conditions found in the two locations. Arctic–alpine plants, for instance, must be adapted to the low temperatures, extremes of temperature, strong winds and short growing season; they are therefore typically low-growing and often form mats or cushions to reduce water loss through evapotranspiration.
Micranthes virginiensis, the early saxifrage, or Virginia saxifrage, is a wildflower native to eastern and central North America.
Heliciopsis is a genus of about thirteen species of trees, constituting part of the flowering plant family Proteaceae. They grow naturally in Burma, Indo-China, SE. China, Thailand, Peninsular Malaysia, Borneo, Sumatra, Java (Indonesia) and the Philippines. The name means similar to the plant genus Helicia. Its closest relatives are Athertonia (Australia) and Virotia.
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 nidifica, the peak saxifrage, is a species of plant in the saxifrage family. It is native to the northwestern United States, where it grows in moist habitat, often in mountainous areas. 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 10 centimeters long with a smooth-edged or minutely toothed blade on a thin petiole. The inflorescence arises on a peduncle up to half a meter tall and bears clusters of flowers with white petals.
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.
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.
Micranthes petiolaris, commonly known as cliff saxifrage, is a species of flowering plant in the saxifrage family. It is native to the Southern Appalachian Mountains where it is found on exposed boulders and rocky seeps, often at high elevation. It is a perennial that produces small white flowers with yellow spots in the summer.
Micranthes californica, known by the common name California saxifrage, is a species of flowering plants.
Micranthes occidentalis, commonly known as western saxifrage, is a species of flowering plant native to North America.
