      Sulphur Flower – E. Bakeri.

      Buckwheat Bush – Eriogonum fasciculatum.

      A pretty desert variety of Wild Buckwheat. The pale downy stem is from one to two feet tall, rather stout, with two or three erect branches at the top, and the leaves are all from the base, gray-green in color and covered with close white down on the under side. The small white and pink flowers are clustered along the branches in small heads, with reddish involucres, forming a spike about three inches long. The whole effect of the plant is curiously pale, but quite pretty. It grows plentifully on the rim of the Grand Canyon.

      There are many kinds of Polygonum, East and West, many of them insignificant, some aquatic, some woody at base, with alternate leaves, and sheathing stipules; the sepals four or five; the stamens five to nine; the style with two or three branches and round-top stigmas. The name is from the Greek, meaning "many knees," in allusion to the swollen joints of some kinds.

      This is about two feet tall, very pretty and rather conspicuous, and the general effect of the smooth stem and sheathing, green leaves is somewhat grasslike. The flowers, which are small and cream-white, with pretty stamens and pinkish bracts, grow in close, roundish, pointed heads, an inch or two long, at the tips of the stalks. The buds are pink and the heads in which the flowers have not yet come out look as if they were made of pink beads. This is an attractive plant, growing among the tall grasses in mountain meadows, and smells deliciously of honey.

      PIGWEED FAMILY. Chenopodiaceae

      A large family, widely distributed, growing usually in salty or alkaline soil; herbs or shrubs, generally succulent and salty or bitter, often covered with white scurf or meal, without stipules; leaves thick, usually alternate, sometimes none; flowers perfect or imperfect, small, greenish, without petals; calyx with two to five sepals, rarely with only one, pistillate flowers sometimes with no calyx; stamens as many as the sepals, or fewer, and opposite them; ovary mostly superior with one to three styles or stigmas; fruit small, dry, with one seed, sometimes with a bladder-like covering. Spinach and Beets belong to this family; many are "weeds," such as Lamb's Quarters.

      Wild Buckwheat – Eriogonum racemosum.

      Alpine Smartweed – Polygonum bistortoides.

      There are two kinds of Grayia, named after Asa Gray; low shrubs; the stamens and pistils in separate flowers, on the same or on different plants.

      An odd and beautiful desert shrub, about three feet high, very dense in form, with interlacing, angular, gray branches, spiny and crowded with small, alternate, toothless leaves, pale-green and thickish, but not stiff. The flowers are small and inconspicuous, but the pistillate ones are enveloped in conspicuous bracts, which enlarge and become papery in fruit, something like those of Docks, and often change from yellowish-green to all sorts of beautiful, bright, warm tints of pink, or to magenta, and the branches become loaded with beautifully shaded bunches of these curious seed-vessels, giving a strange, crowded look to the shrub, which in favorable situations, such as the Mohave Desert, makes splendid masses of color, especially when contrasted with the pale gray of Sage-brush.

      There is only one kind of Cycloloma; leaves alternate, smooth or downy, irregularly toothed; flowers perfect or pistillate, with five sepals, five stamens, and two or three styles; fruit winged horizontally.

      Very curious round plants, six to twenty inches high, usually purple all over, sometimes green and rarely white, giving a brilliant effect in the fall to the sandy wastes they inhabit. They are a mass of interlacing branches, with hardly any leaves, except at the base, and very small flowers. When their seeds are ripe, and they are dry and brittle, the wind easily uproots them and starts them careening across the plain, their seeds flying out by the way. They turn over and over and leap along, as if they were alive, bringing up at last against a wire fence, or some such obstacle, where perhaps a traveler sees them from the train and wonders at the extraordinary-looking, dry, round bunches. There are other Tumble-weeds, such as Tumbling Mustard, Sisymbrium allissimum, and Amaránthus álbus, not of this family.

      Hop Sage – Grayia polygaloides.
