Coptis Trifolia
''Coptis trifolia'', commonly known as the threeleaf goldthread or savoyane, is a perennial plant in the genus ''Coptis'', a member of the family Ranunculaceae. Distribution It is native to North America and Asia across the subarctic region. Its range is divided into three broad groups. The first is from southern Greenland and Labrador that extends to Manitoba to the west and to the mountains of North Carolina to the south. The second is in Alaska and adjacent areas of British Columbia, extending towards eastern Siberia and into Japan and Manchuria. It is also found in Norway and central Russia. The disrupted and wide range of the species suggests that the three populations have been isolated from each other for significant periods of time. Goldthread seems to prefer coniferous or mixed canopies dominated by Eastern hemlock, but it has also been found in deciduous canopies in moist, acidic soils. Description Goldthread has at least one small, deeply three-lobed, evergree ...

Coptis Teeta
''Coptis teeta'' is a rare species of flowering plant in the buttercup family. Medicinal uses It is a species of importance in Chinese herbology. Known as Yunnan goldthread (), its rhizome is used as an antimicrobial and anti-inflammatory. Habitat A number of factors contribute to its endangerment. It is endemic to a very small area in the eastern Himalayas where its habitat is rapidly declining, due in part to deforestation, it is overcollected for medicinal use, and its reproductive success is low. The plant is cultivated on a small scale in Yunnan using techniques that aim to conserve the species within its natural habitat. The Lisu people of the local area earn much of their income from cultivation of the plant, which they grow using traditional agroforestry methods that have little adverse impact on the ecosystem An ecosystem (or ecological system) consists of all the organisms and the physical environment with which they interact. These biotic and abiotic components ...

Coptis Aspleniifolia
''Coptis aspleniifolia'', commonly known as fernleaf goldthread or spleenwort-leaf goldthread, is found in the northern two-thirds of British Columbia, in Alaska, and along the Cascades into Washington and is a native plant of the temperate rain forests of the region. It is often found in the understory of the herb layer of coniferous forests as part of a multilayered canopy system on gleysolic or organic soils. Also found in wetwoods and bogs, the fernleaf goldthread is not invasive or poisonous. The plant is considered common and widespread in its native range. An evergreen perennial, the fernleaf goldthread is mostly hairless and five to 30 centimeters in height. Its leaves resemble those of ferns, are all basal, dark-green and glossy and divided into five or more segments. The fernleaf goldthread blooms in mid-spring with a pale greenish white or yellow flower. It has two or three nodding flowers per stalk, each with five to seven sepals and five to seven thin petals.
