Trollius
a genus of perennial herbaceous plants of the family Ranunculaceae. The stems are erect and only slightly branching; the leaves, which are palmatipartite or lobed, are primarily basal. The flowers are large, usually solitary, yellow or orange, and spherical or more or less flat. The perianth consists of five to 15 petaloid lobes; there are five or more nectary petals, with a nectar pit at the base. The fruit is multiple. There are approximately 30 species, distributed in temperate and cold regions of the northern hemisphere. Twelve species are found in the USSR, mainly in Siberia and the Far East. The globeflower (Trollius europaeus) is widely distributed in European USSR. Many species of Trollius are ornamentals. The most widely cultivated hybrids of globeflower are the large-flowered T. asiaticus and T. chinensis, which are united under the designation T. Х cultorum. O. M.
