Encyclopedia
Trautvetteria is a genus of flowering plants in the buttercup family
. Today it is often considered a monotypic genus, containing only one species, Trautvetteria caroliniensis, which is known by the common names Carolina bugbane, false bugbane, and tassel-rue. A second species, T. japonica, is now generally considered a variety of this species. The genus is named for the botanist Ernst Rudolf von Trautvetter
.
This plant is native to Asia and eastern and western North America. It grows in moist wooded areas and other habitat. It is a rhizomatous
perennial herb producing an erect stem up to 1.5 meters in maximum height. The large leaf has a palmate blade up to 30 or 40 centimeters wide with deeply divided, pointed, toothed lobes. The blade is borne on a long, slender petiole
which may measure up to 45 centimeters long. The leaf is green, darker on top and paler underneath. The inflorescence
is a panicle
with several clusters of flowers on branches. The flower has no petals and is mostly made up of many long, white stamen
s each up to a centimeter long. At the center is a spherical cluster of green pistils
. This develops into a spherical cluster of green fruits.
