Description

These open woodland plants grow to tall.

The leaves that are coarsely toothed with deeply lobed margins. Plants commonly have hairy veins on the undersides of the foliage. Each stem will have either three leaves that branch near the top, or will have three compound leaves and one upright flowering stalk from one point on the main central stem.

Plants produce one to a few ternately branched stems which bear clusters of flowers having 3 to 5 sepals that are petal-like and obovate in shape and remain after flowering. The petals are deciduous, falling away after flowering is done. They are clawed at the base and 2.5 mm to 4 mm long and spatulate to odovate in shape. Flowers have numerous stamens and the are white in color.

After flowering green berries are produced. The fruits are ellipsoid shaped berries containing several seeds. In mid to late simmer, the berries turn bright red or white (forma neglecta). The berries also have a black dot on them.

Distribution

They are found growing in shady areas with moist to wet soils, open forest or dry slopes. In Alaska it ranges from the Kenai Peninsula, through Kodiak Island, Bristol Bay, and up the Yukon River.

Ecology

Plants are slow growing and take a few years to grow large enough to flower. The western subspecies is ssp. arguta, and the northern subspecies is ssp. rubra, these subspecies are not well differentiated, and in many locations, each grades in to the other over much of their ranges. The foliage is rarely consumed by grazing animals. The poisonous berries are harmless to birds, the plants primary seed disperser.

Uses

Plants are sometimes grown in shade gardens for their attractive berries and their upright clump forming habit.

Native Americans used the juice from the fruits of various baneberry species to poison arrows, and used the root as a herbal remedy for menstrual problems.

The root of this species has been used as a strong alternative to Black Cohosh, (Cimicifuga racemosa) for menstrual cramping and menopausal discomfort.

Toxicity

As few as 2 berries may be fatal to a child.

The fruits and foliage contain ranunculine, and are often reported to contain protoanemonin.

All parts of the plant contain an irritant oil that is most concentrated with in the roots and berries.

The roots contain β-sitosterol glucoside.

There have been no reported cases of severe poisoning or deaths in North America, but children have been fatally poisoned by its European relative A. spicata, It is claimed that poisoning is unlikely from eating the fruits of this species also

This plant closely resembles mountain sweetroot, (Osmorhiza chilensis), and can be confused with it, however, Red Baneberry lacks the strong anise-like "spicy celery" odor of mountain sweetroot. DOI: 10.1055/s-2006-951696
