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.

Wild Roses are widely distributed in the northern hemisphere and are too familiar to need much description. There are numerous kinds; some are climbing, all are prickly and thorny, with handsome, often fragrant, flowers and compound leaves, with toothed edges. The numerous yellow stamens are on the thick margin of a silky disk, which nearly closes the mouth of the calyx. The numerous pistils develop into akenes, or small, dry, one-seeded fruits. These look like seeds and we find them inside the calyx-tube, which in ripening enlarges and becomes round or urn-shaped. These swollen calyx-tubes are the "hips," which turn scarlet and add so much to the beauty of the rose-bush when the flowers are gone. Rosa is the ancient Latin name.
