A large and important family, widely distributed and including some of our loveliest flowers and most delicious fruits; herbs, shrubs, or trees; generally with stipules and usually with alternate leaves; the flowers rich in pollen and honey and usually perfect. The calyx usually five-lobed, often with bracts, with a disk adhering to its base; the petals of the same number as the calyx-lobes, separate or none; the stamens usually numerous, separate, with small anthers; the ovary superior, or partly inferior; the pistils few or many, separate or adhering to the calyx, sometimes, as in the true Rose, enclosed and concealed in a hollow receptacle; the fruit of various kinds and shapes.
There are several kinds of Opulaster, branching shrubs, with clusters of white flowers and grayish or reddish, shreddy bark.
[Sidenote: =Ninebark= _Opuláster malvàceus_ (_Physocarpus_) =White Summer Northwest, Utah, Ariz.=]
This is a handsome bush, from three to six feet high, with pretty, almost smooth, bright green leaves, with large stipules. The flowers are sweet-smelling, about half an inch across, with cream-white petals, and form very beautiful and conspicuous rounded clusters, about three inches across, the long stamens giving a very feathery appearance. At a distance this shrub has the effect of Hawthorn in the landscape. It grows on mountainsides in rich soil.
[Sidenote: =Apache Plume= _Fallùgia paradóxa_ =White Spring Ariz., New Mex.=]
There are two kinds of Fallugia. This is usually a low undershrub, but in the Grand Canyon, on the plateau, it is a fine bush, four or five feet high, with pale woody, branching stems; the small, somewhat downy, evergreen leaves, resembling those of the Cliff Rose, but the flowers larger. They are white, two inches across, like a Wild Rose in shape, with beautiful golden centers, and grow on long, slender, downy flower-stalks, at the ends of the branches. Individually, they are handsomer than the flowers of the Cliff Rose, but not nearly so effective, as the bloom is much more scattered. The calyx-tube is downy inside and the five sepals alternate with five, small, long, narrow bractlets. The hairy pistils are on a small conical receptacle, surrounded by a triple row of very numerous stamens on the margin of the calyx-tube.
