This is our only kind of Trollius. It is an exceedingly beautiful flower, particularly when found growing in the snow, or near the edge of a field of melting ice, in high mountains and along the margins of glaciers. The handsome, toothed leaves are palmately-lobed or divided, the lower ones with long leaf-stalks, rich green and glossy and setting off the flowers, which grow singly at the tips of smooth, rather weak stems, from one to two feet tall, and measure about an inch and a half across. The sepals, from five to seven in number, are large, cream-white, slightly greenish outside, and are the conspicuous part of the flower, for the petals are very small and yellow, so that they resemble stamens. From fifteen to twenty-five of these little petals, in a row, surround the numerous, real stamens and form a beautiful golden center. The fruit is a head, measuring an inch across, composed of eight to fifteen small pods, with beaks, containing many, smooth, oblong seeds. This plant looks very much like an Anemone but it has these small yellow petals and Anemones have none, and the center is larger and brighter yellow and the foliage coarser.
There are three kinds of Trautvetteria, two American and one Asiatic.
