There are only a few kinds of Actaea, tall perennials, with large, alternate, thrice-compound leaves and small, white flowers, in short, terminal clusters. The sepals number about four and resemble petals; the petals are from four to ten, or sometimes none, with claws; the stamens are numerous, with conspicuous white filaments; the one pistil has a broad, somewhat two-lobed, stigma, and the fruit is a large, showy, red or white, somewhat poisonous berry, containing many, smooth, flat seeds.

This is a fine plant, from one to two feet tall, with a stoutish, smooth, branching stem and handsome leaves, prettily cut, with pointed teeth, thin and soft in texture, with conspicuous veins. The sepals and petals of the small cream-white flowers are less conspicuous than the numerous white stamens, which give a very feathery appearance to the flower-cluster, which is one or two inches long and speckled with the dark tips of the pistils. The sepals and petals drop off early and the stamens lengthen, so that the cluster becomes very airy and delicate. The general effect of the plant, which grows near shady mountain streams, is striking and graceful. It grows also in the East and is sometimes slightly sweet-scented, but often has an unpleasant smell. The handsome, poisonous berries are oval or round, red or white, with a polished surface, and contain many seeds. This reaches an altitude of ten thousand feet. A very similar kind, A. viridiflòra, grows in the mountains of Arizona.

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.
