Potentilla basaltica Tiehm & Ertter | |
Potentilla basaltica is a species of flowering plant in the rose family known by the common names Soldier Meadows cinquefoil [2] and basalt cinquefoil. [3] It is endemic to a small area of the Modoc Plateau and Warner Mountains in northeastern California and northwestern Nevada. [4]
Potentilla basaltica occurs in the Black Rock Desert of Humboldt County, Nevada, and Lassen County, California, where there are a total of four occurrences. It grows in moist alkaline meadows near streams and springs.
Associated species include: Juncus balticus , Scirpus maritimus , Scirpus acutus, Triglochin maritima , Distichlis spicata , Sisyrinchium halophilum , Nitrophila occidentalis , Carex spp., Pyrrocoma racemosa , Solidago spectabilis , Sphaeromeria potentilloides , Astragalus argophyllus, Lotus purshianus , Ericameria nauseosa , and Sarcobatus vermiculatus . [4]
Potentilla basaltica is a perennial herb grows from a thick taproot and has a base covered in the remnants of previous seasons' leaves. The stems are usually prostrate or decumbent, spreading along the ground, or occasionally growing upright.
Stems are up to 50 centimeters long and may be purple-tinged. Most of the leaves are located around the base of the plant. They are each divided into several pairs of leaflets. There are a few smaller leaves located along the stems.
The flowers at the ends of the stems have bright yellow petals. [4] [5]
This rare species is a candidate for federal protection. The Bureau of Land Management has enacted conservation measures such as fencing populations to exclude grazing animals and closing roads in vulnerable habitat. [6] Current threats include changes in local hydrology and the invasion of noxious weeds, such as Lepidium latifolium . The populations are apparently stable for the time being. [4]
This species is a host for the fungus Phragmidium ivesiae . [6]
Despite its specific epithet, P. basaltica is not found on basalt or basalt-derived soils. It is named for the Black Rock Desert itself, which is in turn named for a basalt-capped peak at one end of the adjacent Black Rock Range. [5]
Potentilla hickmanii is an endangered perennial herb of the rose family. This rare plant species is found in a narrowly restricted range in two locations in coastal northern California, in Monterey County, and in very small colonies in San Mateo County. This small wildflower, endemic to western slopes of the outer coastal range along the Pacific Ocean coast, produces bright yellow blossoms through spring and summer.
Potentilla recta, the sulphur cinquefoil or rough-fruited cinquefoil, is a species of cinquefoil. It is native to Eurasia but it is present in North America as an introduced species, ranging through almost the entire continent except the northernmost part of Canada and Alaska.
Potentilla robbinsiana, the dwarf mountain cinquefoil or Robbins' cinquefoil, is a small, yellow-flowered, perennial found exclusively above the tree line in the White Mountains of New Hampshire. The plant is nearly stemless and measures two to four centimeters in diameter.
Potentilla diversifolia or Potentilla × diversifolia is a species of flowering plant in the Rose Family (Rosaceae) known by the common names varileaf cinquefoil, different-leaved cinquefoil, and mountain meadow cinquefoil.
Potentilla flabellifolia is a species of cinquefoil known by the common names high mountain cinquefoil, fanleaf cinquefoil and fan-foil.
Potentilla grayi is a species of cinquefoil known by the common name Gray's cinquefoil.
Potentilla millefolia is a species of cinquefoil known by the common names cutleaf cinquefoil and feather cinquefoil. It is native to Oregon, Nevada and eastern California, where it grows in moist mountain meadows and similar habitat. The plant produces a basal rosette from a taproot, then a decumbent stem up to about 20 centimeters in maximum length. The elongated leaves are made up of several overlapping pairs of deeply lobed leaflets. The inflorescence at the tip of the stem is a cyme of a few flowers, each with usually five yellow petals under a centimeter long.
Potentilla norvegica is a species of cinquefoil known by the common names rough cinquefoil, ternate-leaved cinquefoil, and Norwegian cinquefoil. It is native to Europe, Asia, and parts of North America, and it can be found elsewhere as an introduced species.
Potentilla pseudosericea is a species of cinquefoil known by the common names silky cinquefoil and Mono cinquefoil. It is native to the Sierra Nevada of California and mountain ranges just to the east, where its distribution extends into Nevada. It grows in rocky mountainous habitat. It is a small plant forming mats or tufts in rock cracks and talus, its short stem growing from a caudex. The leaves are generally palmate, divided into five leaflets. The leaflets are deeply lobed along the edges and woolly in texture, coated in white or silvery hairs. The inflorescence is a cluster of a few yellow flowers with petals around 3 millimeters long each.
Potentilla rimicola is a species of cinquefoil-Potentilla, known by the common name cliff cinquefoil.
Scirpus congdonii is a species of flowering plant in the sedge family known by the common name Congdon's bulrush after noted Californian botanist J.W. Congdon. It is native to the mountains and plateaus of far northern California and adjacent sections of southern Oregon and western Nevada. It can be found in wetland habitat and other moist areas, such as mountain meadows and waterways. It is a perennial herb forming a loose or dense clump of erect stems growing up to half a meter tall, solitary stems sometimes occurring as well. The stems are three-angled and narrow at the middle. Sheathing leaves occur at the stem bases as well as higher up the stems. The inflorescence occurs at the end of the stem, with small additional ones growing from leaf axils. The inflorescence consists of several clusters of many spikelets wrapped at the bases in a leaflike bract.
Scirpus diffusus is a species of flowering plant in the sedge family known by the common name umbrella bulrush. It is endemic to California, where it can be found in several of the high mountain ranges from the Klamath Mountains to the Sierra Nevada. It grows in wetland habitat and other moist areas, such as mountain meadows. It is similar to Scirpus congdonii and was described from herbarium specimens once mislabeled as such. It is a perennial herb forming a clump of erect stems growing up to a meter tall, solitary stems sometimes occurring as well. The stems are three-angled and narrow at the middle. Sheathing leaves occur at the stem bases as well as higher up the stems. The inflorescence occurs at the end of the stem, with small additional ones growing from the uppermost leaf axial. The inflorescence consists of several clusters of many spikelets wrapped at the bases in a leaflike bract.
Potentilla villosa is a species of flowering plant in the rose family, Rosaceae. Its common names include villous cinquefoil, northern cinquefoil, and hairy cinquefoil.

It is native to the northeastern United States from New Hampshire south to Virginia. It used to be found in Quebec but it is now thought to be extirpated there. It was also believed extirpated from the state of New York, but at least one population has been rediscovered in Steuben County in 2010. It is threatened by the loss and degradation of its wetland habitat. It is a federally listed endangered species.
Potentilla cottamii is a rare species of flowering plant in the rose family known by the common names Cottam's cinquefoil and Pilot Range cinquefoil. It is native to Nevada and Utah in the United States. It occurs in the Pilot Range of Elko County, Nevada, and a small area of adjacent Utah.
