Iris pseudacorus, the yellow flag, yellow iris, or water flag, is a species of flowering plant in the family Iridaceae. It is native to Europe, western Asia and northwest Africa. Its specific epithet pseudacorus means "false acorus", referring to the similarity of its leaves to those of Acorus calamus, as they have a prominently veined mid-rib and sword-like shape.

Jeffersonia, also known as twinleaf or rheumatism root, is a small genus of herbaceous perennial plants in the family Berberidaceae. They are uncommon spring wildflowers and grow in limestone soils of rich deciduous forests. Jeffersonia was named for United States President Thomas Jefferson by his contemporary Benjamin Smith Barton. This genus was formerly grouped in genus Podophyllum. Twinleaf is protected by state laws as a threatened or endangered plant in Georgia, Iowa, New York, and New Jersey.
Caulophyllum is a small genus of perennial herbs belonging to the family Berberidaceae and closely related to the Eurasian genera Leontice and Gymnospermium. It is native to eastern Asia and eastern North America. These plants are distinctive spring wildflowers, which grow in moist, rich woodland, it is known for its large triple-compound leaf, and large blue, berry-like fruits. Unlike many spring wildflowers, it is not an ephemeral plant and persists throughout much of the summer. Common names for plants in this genus include blue cohosh, squaw root, and papoose root. As hinted at by its common names, this plant is well known as an alternative medicine for inducing childbirth and menstrual flow; it is also considered a poisonous plant.

Ranzania is a monotypic genus of perennial herbs in the family Berberidaceae. The only species is Ranzania japonica. It is native to woodlands in the mountains of Honshu, Japan. This genus is named in honor of Ono Ranzan, who has been called "the Japanese Linnaeus". Fleshy stems of Ranzania form small colonies from an underground rhizome. Each stem bears two trifoliate compound leaves, and between the leaves is a single or more commonly a small cluster of drooping cup-shaped mauve flowers. These develop into an upright cluster of white berries. The haploid chromosome number is n=7.
Bryonia alba is a vigorous vine in the family Cucurbitaceae, found in Europe and Northern Iran. It has a growth habit similar to kudzu, which gives it a highly destructive potential outside its native range as a noxious weed. Other common names include false mandrake, English mandrake, wild vine, and wild hops, wild nep, tamus, ladies' seal, and tetterbury.
Plant sources of anti-cancer agents are plants, the derivatives of which have been shown to be usable for the treatment or prevention of cancer in humans.
