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. Records from Norway and central Russia are most likely based on confusion. 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, ...

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 over-collected 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) is a system formed by Organism, organisms in interaction with their Biophysical environment, environment.
