СКАЧАТЬ 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.

      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.

      Hop Sage

      Gràyia spinòsa

      (G. polygaloides)

      Greenish, with red bracts

      Spring

      Calif., Nev., Utah, Ariz.

      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.

      Tumbleweed

      Cyclolòma atriplicifòlium

      Purple or green

      Summer

      West of Mississippi River

      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.

      FOUR-O'CLOCK FAMILY. Nyctaginaceae

      A rather large family, widely distributed, most abundant in America. Ours are herbs, often succulent, with no stipules; stems often fragile, swollen at the joints; leaves opposite, usually toothless, often unequal; flowers perfect, with no petals, but the calyx colored like a corolla, with four or five lobes or teeth, and more or less funnel-shaped; one or several flowers in a cluster with an involucre; stamens three to five, with slender filaments; style one, with a round-top stigma; the green base of the calyx drawn down around the ovary, making it appear inferior, and hardening into a nutlike fruit; seeds sometimes winged.

      Quamoclidions have the odd habit of opening in the afternoon, hence the common name, Four-o'clock. The flowers usually have five stamens, and are grouped several together in a cluster, which emerges from an involucre so much resembling a calyx that it is often mistaken for one. The effect is of the flowers having clubbed together and made one calyx do for the lot. The fruit is hard, smooth, and roundish.

      Four-o'clock

      Quamoclídion multiflòrum.

      (Mirabilis)

      Pink, purple

      Spring

      Southwest and Col.

      The leaves of this low, stout, and spreading perennial are an inch or two long, light bluish-green, somewhat heart-shaped, rather rough and coarse, and the stems are often hairy and sticky. The foliage contrasts strikingly in color with the gaudy pink or magenta flowers, an inch across and slightly sweet-scented, the shape of Morning-glories and resembling them, as they have the same stripes of deeper color. The long stamens droop to one side, the pistil is long and purple and the bell-shaped involucre contains about six flowers. These plants are conspicuous and quite handsome. They grow on the plateau in the Grand Canyon.

      There are several kinds of Hesperonia, much like Quamoclidion, but the bell-shaped involucre contains only one flower, which is also bell-shaped, usually with five separate stamens. The fruit is roundish, not angled or ribbed, usually smooth.
