Bistorta
''Bistorta'' is a genus of flowering plants in the family Polygonaceae. about 40 species are accepted. It has been supported as a separate clade by molecular phylogenetic analysis. ''Bistorta'' species are native throughout much of the Northern Hemisphere, as far south as Mexico in North America and Thailand in Asia. Description Species of ''Bistorta'' are perennial herbaceous plants. Their roots are fibrous, forming rhizomes. They have erect, unbranched stems. Their leaves are usually longer than wide, mostly basal, but with some arranged alternately on the stems. The inflorescences are spikelike. The individual flowers have five white to purple-pink (rarely red) tepals. The flowers are bisexual, although the 5–8 stamens are sometimes poorly developed. There are three styles. The fruits are in the form of achenes, that are brown or dark brown, unwinged, and three-angled. The monoploid number of chromosomes, ''x'', is 11 or 12.

Bistorta Bistortoides
''Bistorta bistortoides'' (American bistort, western bistort, smokeweed, mountain meadow knotweed, mountain buckwheat or mountain meadow buckwheat) is a perennial herb in the buckwheat and knotweed family Polygonaceae. The species name remains unresolved. ''Bistorta bistortoides'' is distributed throughout the Mountain West in North America from Alaska and British Columbia south into California and east into the Rocky Mountains. ''Bistorta bistortoides'' grows from foothills to above the timberline, although plants growing above 7,500 feet (2250 m) are smaller and seldom reach more than 12 inches (30 cm) in height. Plants in other areas may reach over half a meter–1.5 feet (20–60 cm) tall. The leaves are leathery and up to 40 centimeters (3 feet) long, and are mostly basal on the stem. The dense cylindrical to oblong inflorescence is packed with small white to pinkish flowers, each a few millimeters wide and with protruding stamens. Rodents and bears consume the ro ...
