description
Vegetative characteristics
The Trollius species are perennial herbaceous plants . All species are as good as bald.
There are undergraduate and exchange constant for most species distributed on the stem leaves . The leaf stalks are shorter, the higher the leaves are on the stem. In most species, the leaves are finger-shaped divided into five to seven obovate, three-lobed sections, or at least cut very deep finger-shaped.
Generative characteristics
In terminal inflorescences there are one to three flowers together, or individually on long pedicels. The hermaphroditic flowers are radial symmetry . There are five to nine sepals , rarely more , they are colored like a petal, mostly yellow, but in some species also whitish, orange or reddish, in one species also bluish-purple. They are usually broadly oval or rounded. In some species they are curved in such a way that the entire flower has a spherical shape. Most of them, however, are flat. The petals are colored similarly to the sepals, but much narrower, mostly linear to narrow oval, and nailed briefly at the base. There are nectaries just above the base of the petals .
The pelvic fruits consist of beaked follicle fruits.
Location requirements
The Trollius species occur in temperate to arctic climates . They prefer open, wet locations such as wet meadows and heavy, clayey soils.
