A large family, widely distributed, mostly herbs or low shrubs, with toothless leaves, often with stipules sheathing the swollen joints of the stem. The small flowers have no petals, the calyx usually resembles a corolla and has from three to six divisions. There are from four to nine stamens and a superior, mostly triangular, ovary, with two or three styles or stigmas, becoming a dry, one-seeded fruit, generally brown or black. The kind from which flour is made is cultivated from northern Asia, and the name Buckwheat, from the German, means "beech-wheat," because the grain resembles minute beech-nuts. There are several common "weeds" belonging to this family, such as Dock, Sorrel, and Smartweed.

Chorizanthes are low herbs, with branching stems, without stipules, the leaves forming a rosette at the base and withering early. The small flowers have six sepals and are clustered in small heads, usually one flower in each papery involucre, which has from two to six teeth, with bristles at the tips; stamens usually nine, on the base of the perianth; styles three, with round-top stigmas.

Turkish Rugging

Chorizánthe fimbriàta

Pink

Spring

California

An odd, dry-looking plant, making pretty patches of purplish color on dry mesas. The stiff, roughish, purplish stem is a few inches tall, springing from a few dull-green or reddish root-leaves, branching abruptly and widely towards the top and bearing many small flowers. The involucres are deep-red or purple, with very prickly teeth, the sepals bright-pink, prettily fringed with white and striped with deeper color, and the filaments are long and threadlike, with purple anthers. The flowers are exceedingly pretty when closely examined, though too small to be very effective, but the plant as a whole is conspicuous both in color and form. C. staticoìdes is similar, but the sepals are not fringed.

Turkish Rugging – Chorizanthe fimbriata.

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.

Sand Dock

Rùmex venòsus

Greenish

Spring, summer

West

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.

Bottle-plant

Eriógonum inflàtum

Yellow

Spring

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.

Swollen-stalk

Eriógonum elàtum

White, pink

Summer

Northwest

This is about a foot and a half tall and the stem is swollen, but not so much so as the last, and the flowers are more conspicuous, forming rather flat-topped clusters, about three-quarters of an inch across. The tiny flowers are cream-white or pinkish, the buds are deep-pink, and the stamens are long, with tiny, pinkish anthers. The leaves are dull-green on the upper side and pale with close down on the under and grow in a cluster at the base.

Swollen-stalk – E. elatum.

Bottle-plant – Eriogonum inflatum.

Butter Balls, Snow Balls

Eriógonum orthocàulon

Yellow, white

Spring, summer

Northwest

These are attractive plants, with pretty odd little balls of flowers, and are very conspicuous on dry, rocky mesas. They have a number of slender, pale, downy stems, about ten inches tall, springing from a close clump of small, dull-green leaves, pale with down on both sides and the smaller ones almost white, and bearing at the tip a dense flower-cluster, about an inch and a half across, which is very fuzzy and pretty. The little flowers have cream-color, downy involucres, the outer sepals are broader than the inner, and the pedicels, stamens, and pistil are all the same color as the sepals, either very bright sulphur-yellow or cream-white, but not mixed on the same plant, and sometimes tinged with red. These flowers are very popular with children in Idaho and they make necklaces of the fuzzy balls, something like "daisy chains."

Eriógonum compósitum

White, yellow

Summer

Northwest

This is a big handsome plant, with a thick, smooth stem, one or two feet tall and woody at base, and with thickish leaves, slightly downy, dark green in color on the upper side and white with close down on the under. The flowers form feathery, cream-white or yellow clusters, often more than six inches across, with red buds, and are beautiful and conspicuous on bare mountainsides, smelling of honey.

Butter Balls – Eriogonum orthocaulon.

Eriogonum compositum.

Buckwheat Bush, Flat-top

Eriógonum fasciculàtum

White

Spring, summer

Southwest

In favorable situations this is an attractive shrub, from two to four feet high, with shreddy, reddish bark and long, straight branches, standing stiffly up and crowded with small, thickish, stiffish leaves, dark olive-green on the upper side and pale with down on the under, with rolled-back margins. The flowers are about three-eighths of an inch across, dull-white or pinkish, with pink buds, forming large, feathery, flat-topped clusters, on long, stiff, bare, reddish flower-stalks, standing up stiffly all over the bush. This is a very valuable bee-plant and grows on mesas and mountain slopes.

Sulphur Flower

Eriógonum Bàkeri

Yellow

Summer

Ariz., Utah, New Mex., Col., Wyo.

This plant is quite pretty and conspicuous, as the flowers are bright in color and a peculiar shade of sulphur yellow. The stem is downy and often reddish, about a foot tall, with two or three branches at the top, each bearing a cluster of numerous small sweet-scented flowers with pretty stamens. The gray-green leaves grow mostly in a rosette on the ground and are covered with close white down on the under side. Their soft tints tone in well with the bright color of the flowers and the pale sandy soil in which they grow. E. flàvum is similar and widely distributed. E. incànum is the same color but much smaller, often tinged with red, the gray leaves forming a dense velvety mat, and it grows at high altitudes, in sandy spots on rocks, and is found around the Yosemite Valley. The alpine form is very small. There are several other kinds of Sulphur Flower.

Sulphur Flower – E. Bakeri.

Buckwheat Bush – Eriogonum fasciculatum.

Wild Buckwheat

Eriógonum racemòsum

Pink, white

Summer

Ariz., Utah

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.

Knot-weed

Alpine Smartweed

Polýgonum bistortoìdes

White

Summer

West

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.
