There are many kinds of Rumex, or Dock, coarse herbs, with leafy, branching, grooved stems, sheathed with conspicuous, papery stipules, strong tap-roots and acid or bitter juice. The large leaves are alternate, with smooth or wavy edges; the flowers small, greenish or reddish, on jointed pedicels, in branching clusters; the stamens six; the styles three, the stigmas shield-shaped, with a tuft of hairs at the tip. The six divisions of the flower are in two sets, the three outer small and green, the inner ones larger, colored and becoming veiny and larger in fruit, forming valves or wings, (often with a grain on the back of one or all of them,) which closely cover the three-sided fruit. These wings make the fruits of Docks more conspicuous than the flower. The Latin name comes from a word meaning "to suck," because the Romans sucked the leaves to allay thirst.

In favorable situations this is a very handsome member of a rather plain genus, about a foot tall, with a smooth, stout reddish stem and smooth, pale, blue-green leaves, that feel like thin rubber, with a prominent mid-vein front and back. The small inconspicuous flowers develop into clusters of showy valves or wings, wonderfully odd and beautiful in coloring, resembling Begonia flowers. At first these wings are pale green, but they gradually brighten until they are all shades of salmon, rose-color, and red, fading to brown, and forming lovely combinations of vivid color, particularly against the arid background of the sand hills they frequent, and they last a long time in water and are exceedingly decorative. If these wings, which are nearly an inch across, are pulled apart, a three-sided akene, like a little nut, will be found inside them.
Sand Dock—Rumex venosus.
There are many kinds of Eriogonum, herbs or shrubs, natives of America, mostly western, growing in dry places, very numerous and difficult to distinguish. The leaves, without sheaths or stipules, are often covered with white down and usually grow in a spreading cluster at the base of the stem. The numerous small flowers, on very slender little pedicels, have six sepals, thin in texture and usually colored, and form clusters of various shapes, which emerge from more or less bell-shaped or top-shaped involucres, with six teeth. There are nine stamens, with threadlike filaments, often hairy, and a three-parted style with round-top stigmas. The name is from the Greek meaning "wooly knees," in allusion to the wooly joints of the stem.

Southwest
This is a most extraordinary looking plant, with queer inflated, hollow stalks, about two feet high, swelling larger towards the top, and the branches, which are also swollen, sticking out awkwardly in all directions and bearing a few minute, yellow flowers. The stalks, which are pale bluish-green, suggest some strange sort of reed, but the dark-green leaves, growing in a rosette at the base, are something like the leaves of cultivated violets and seem entirely out of keeping with the rest of the plant. This grows on the plateau in the Grand Canyon and in similar places.
