Thalictrum

See text Thalictrum ( /θəˈlɪktrəm/) is a genus of 120-200 species of herbaceous perennial flowering plants in the buttercup family, Ranunculaceae, native mostly to temperate regions.

Despite their common name of "meadow-rue", Thalictrum species are not closely related to the true rue (family Rutaceae), but resemble its members in having compound leaves twice or thrice divided.

[citation needed] The flowers are small and apetalous (no petals), but have numerous long stamens, often brightly white, yellow, pink or pale purple, and are produced in conspicuous dense inflorescences.

In some species (e.g. T. chelidonii, T. tuberosum), the sepals are large, brightly coloured and petal-like, but in most they are small and fall when the flower opens or soon after.

[citation needed] Thalictrum species are valued as ornamental garden plants, with their sprays of flowers in delicate shades.
