Happy must the honeybees have been to find that the sweet clover, one of their dearest delights in the Old World, had preceded them in immigrating to the New. Immense numbers of insects - bees in great variety, wasps, flies, moths, and beetles - visit the little blossoms that provide entertainment so generous and accessible; but honey-bees are ever especially abundant. Slight weight depresses the keel, releasing the stigma and anthers therefore, so soon as a bee alights and opens the flower, he is. .h.i.t below the belt by the projecting stigma. Pollen carried by him there from other clovers comes off on its sticky surface before his abdomen gets freshly dusted from the anthers, which are necessarily rubbed against while he sips nectar. On the removal of his pressure, the floret springs back to its closed condition, to protect the precious nectar and pollen from rain and pilferers. As the stigma projects too far beyond the anthers to be likely to receive any of the flower's own pollen, good reason is there for the blossoms guarding their attractions for the benefit of their friends, which transfer the vitalizing dust from one floret to another. By cl.u.s.tering its small flowers in spikes, to make them conspicuous, as well as to facilitate dining for its benefactors; by prolonging its season of bloom, to get relief from the fiercest compet.i.tion for insect trade, and so to insure an abundance of vigorous cross-fertilized seed, this plant reveals at a glance some of the reasons why it has been able to establish itself so quickly throughout our vast area.

Both the white and the yellow sweet clover put their leaves to sleep at night in a remarkable manner: the three leaflets of each leaf twist through an angle of 90 degrees, until one edge of each vertical blade is uppermost. The two side leaflets, Darwin found, always tend to face the north with their upper surface, one facing north-northwest and the other north-northeast, while the terminal leaflet escapes the chilling of its sensitive upper surface through radiation by twisting to a vertical also, but bending to either east or west, until it comes in contact with the vertical upper surface of either of the side leaflets. Thus the upper surface of the terminal and of at least one of the side leaflets is sure to be well protected through the night; one is "left out in the cold."

The dried branches of sweet clover will fill a room with delightful fragrance; but they will not drive away flies, nor protect woolens from the ravages of moths, as old women once taught us to believe.

The ubiquitous WHITE or DUTCH CLOVER (Trifolium repens), whose creeping branches send up solitary round heads of white or pinkish flowers on erect, leafless stems, from May to December, in fields, open waste land, and cultivated places throughout our area, Europe, and Asia, devotes itself to wooing bees, since these are the only insects that effect cross-fertilization regularly, other visitors aiding it only occasionally. When nets are stretched over these flowers to exclude insects, only one-tenth the normal quant.i.ty of fertile seed is set. Therefore, for the bee's benefit, does each little floret conceal nectar in a tube so deep that small pilferers cannot reach it; but when a honeybee, for example, depresses the keel of the papilionaceous blossom, abundant reward awaits him in consideration of his services in transferring pollen. After the floret which he has been the means of fertilizing closes over its seed-vessel on his departure, it gradually withers, grows brown, and hangs downward, partly to indicate to the next bee that comes along which fords in the head still contain nectar, and which are done for; partly to hide the precious little vigorous green seed-pod in the center of each withered, papery corolla from the visitation of certain insects whose minute grubs destroy countless millions of the progeny of less careful plants. Thus the erect florets in a head stand awaiting their benefactors; those drooping around the outer edge are engaged in the most serious business of life. Sometimes a solitary old maid remains standing, looking anxiously for a lover, at the end of the season. Usually all the florets are then bent down around the stem in a brown and crumpled ma.s.s. But however successfully the clover guards its seeds from annihilation, its foliage is the favorite food of very many species of caterpillars and of all grazing cattle the world around. This is still another plant frequently miscalled shamrock. Good luck or bad attends the finding of the leaves, when compounded of an even or an odd number of leaflets more than the normal count, according to the saying of many simple-minded folk.

The little RABBIT'S-FOOT, p.u.s.s.y, OLD-FIELD, or STONE CLOVER (T.

arvense) has silky plumed calices to hold its minute whitish florets, giving the dense, oblong heads a charming softness and dove color after it has gone to seed. Like most other clovers, it has come to us from the Old World.

FLOWERING SPURGE (Euphorbia corollata) Spurge family

Flowers - (Apparently) white, small, borne in forked, long-stalked umbels, subtended by green bracts; but the true flowers are minute, and situated within the white cup-shaped involucre, usually mistaken for a corolla. Staminate flowers scattered over inner surface of involucre, each composed of a single stamen on a thread-like pedicel with a rudimentary calyx or tiny bract below it. A solitary pistillate flower at bottom of involucre, consisting of 3-celled ovary; 3 styles, 2-cleft, at length forming an erect 3-lobed capsule separating into 3 2-valved carpels. Stem: 1 to 3 ft. high, often brightly spotted, simple below, umbellately 5-branched above (usually). Leaves: Linear, lance-shaped or oblong, entire; lower ones alternate, upper ones whorled.

Preferred Habitat - Dry soil, gravelly or sandy.

Flowering Season - April-October.

Distribution - From Kansas and Ontario to the Atlantic.

A very commonplace and uninteresting looking weed is this spurge, which no one but a botanist would suspect of kins.h.i.+p with the brilliant vermilion poinsettia, so commonly grown in American greenhouses. Examination shows that these little bright white cups of the flowering spurge, simulating a five-cleft corolla, are no more the true flowers in the one case than the large red bracts around the poinsettia's globular greenish blossom involucres are in the other. From the milky juice alone one might guess the spurge to be related to the rubber plant. Still another familiar cousin is the stately castor-oil plant; and while the common dull purplish IPECAC SPURGE (E. Ipecacuanhae) also suggests unpleasant doses, it is really a member of quite another family that furnishes the old-fas.h.i.+oned emetic. The flowering spurge, having its staminate and pistillate flowers distinct, depends upon flies, its truest benefactors, to transfer pollen from the former to the latter.

STAGHORN SUMAC; VINEGAR TREE (Rhus hirta; R. typhina of Gray) Sumac family

Flowers - Greenish or yellowish white, very small, usually 5-parted, and borne in dense upright, terminal, pyramidal cl.u.s.ters. Stem: A shrub or small tree, 6 to 40 ft. high, the ends of branches forked somewhat like a stag's horns. Leaves.

Compounded of 11 to 31 lance-shaped, saw-edged leaflets, dark green above, pale below; the petioles and twigs often velvety-hairy. Fruit: Small globules, very thickly covered with crimson hairs.

Preferred Habitat - Dry, rough or rocky places, banks, roadsides.

Flowering Season - June.

Distribution - Nova Scotia to Georgia, and westward 1500 miles.

Painted with glorious scarlet, crimson, and gold, the autumnal foliage of the sumacs, and even the fruit, so far eclipse their inconspicuous flowers in attractiveness that one quite ignores them. Not so the small, short-tongued bees (chiefly Andrenidae) and flies (Dipteria) seeking the freely exposed nectar secreted in five orange-colored glands in the shallow little cups. As some of the flowers are staminate and some pistillate, although others show a tendency to revert to the perfect condition of their ancestors, it behooves them to entertain their little pollen-carrying visitors generously, otherwise no seed can possibly be set. And how the autumnal landscape would suffer from the loss of the decorative, dark-red, velvety panicles! Beware only of the poison sumac's deadly, round grayish-white berries.

Most sumacs contain more or less tannin in their bark and leaves, that are therefore eagerly sought by agents for the leather merchants. The beautiful SMOKE or MIST TREE (R. cotinus), commonly imported from southern Europe to adorn our lawns (although a similar species grows wild in the Southwest), serves a more utilitarian purpose in supplying commerce with a rich orange-yellow dye-wood known as young fustic. All this tribe of shrubs and trees contain resinous, milky juice, drying dark like varnish, which in a j.a.panese species is transformed by the clever native artisans into their famous lacquer. With a commercial instinct worthy of the Hebrew, they guard this process as a national secret.

The SMOOTH, UPLAND, or SCARLET SUMAC (R. glabra), similar to the staghorn, but lacking its velvety down, and usually of much lower growth, is the very common and widely distributed shrub of dry roadsides, railroad banks, and barren fields. Another low-growing, but more or less downy upland sumac, the DWARF, BLACK, or MOUNTAIN SUMAC (R. copallina), may be known by its dark, glossy green foliage, pale on the underside, and by the broadening of the stem into wings between the leaflets. Hungry migrating birds alight to feast on the harmless acid red fruit when the gorgeous autumnal foliage illuminates their route southward. But while they are, of course, the natural agents for distributing the plants over the country, men find that by cutting bits of any sumac root and planting them in good garden soil, strong specimens are secured within a year. An exquisite cut-leaved variety of the smooth sumac adorns many fine lawns.

Everyone should know the POISON SUMAC (R. Vernix - R. venenata of Gray) as the shrub above all others to avoid. Like its cousin, the POISON or THREE-LEAVED IVY (R. radicans), which once had the specific name Toxicodendron, although Linnaeus applied that t.i.tle to a hairy shrub of the Southern States, the poison sumac causes most painful swelling and irritation to the skin of some people, though they do nothing more than pa.s.s it by when the wind is blowing over it. Others may handle both these plants with impunity. In spring they are especially noisome; but when the pores of the skin are opened by perspiration, people who are at all sensitive should give them a wide berth at any season.

Usually the poison sumac grows in wet or swampy ground; its bark is gray, its leaf-stalks are red; the leaves are compounded, of fewer leaflets than those of the innocent sumacs - that is, of from seven to thirteen - which are green on both sides; the flowers, which are dull whitish-green, grow in loose panicles from the axils of the leaves, and naturally the berries follow them in the same unusual situation. "By their fruits ye shall know them:" all the harmless sumacs have red fruit cl.u.s.ters at the ends of the branches, whereas both the poison sumac's and the poison ivy's axillary cl.u.s.ters are dull grayish-white.

AMERICAN HOLLY (Ilex opaca) Holly family

Flowers - Very small, greenish or yellowish white, from 3 to 10 staminate ones in a short cyme; fertile flowers usually solitary, scattered. Stem: A small tree of very slow growth, rarely attaining any great height. Leaves: Evergreen, thick, rigid, glossy, elliptical, scalloped edged, spiny-tipped. Fruit: Round, red berries.

Preferred Habitat - Moist woods and thickets.

Flowering Season - April-June.

Distribution - Maine to the Gulf of Mexico, west to Texas, chiefly near the coast and south of New York.

Happily we continue to borrow all the beautiful Old World a.s.sociations, poetical and legendary, that cl.u.s.ter about the holly at Christmas time, although our native tree furnishes most of our holiday decorations. So far back as Pliny's day, the European holly had all manner of supernatural qualities attributed to it: its insignificant little flowers caused water to freeze, he tells us; because it was believed to repel lightning, the Romans planted it near their houses; and a branch of it thrown after any refractory animal, even if it did not hit him, would subdue him instantly, and cause him to lie down meekly beside the stick! Can it be that the Italian peasants, who still believe cattle kneel in their stalls at midnight on the anniversary of Jesus' birth, decorate the mangers on Christmas eve with holly, among other plants, because of a survival of this old pagan notion about its subduing effect on animals?

Would that the beautiful holly of English gardens (I.

Aquifolium), more glossy and spiny of leaf and redder of berry than our own, might live here; but it is too tender to withstand New England winters, and the hot, dry summers farther south soon prove fatal. Ilex was the ancient name, not of these plants, but of the holly oak.

The MOUNTAIN HOLLY (Ilicioides mucronata - Nemopanthes Canadensis of Gray) a shrub of the northern swamps, about six feet high, and by no means confined to mountainous regions, since it is also abundant in the middle West, has smooth-edged, elliptic, petioled leaves, ash-colored bark, small, solitary, narrow-petalled staminate and pistillate flowers on long, threadlike pedicels from the leaf-axils in May. In August dull pale-red berries appear. Darwin proved that seed set with the help of pollen brought from distinct plants produces offspring that vanquishes the offspring of seed set with pollen brought from another flower on the same plant in the struggle for existence. Thus we see, in very many ambitious plants besides those of the holly tribe, a tendency to separate the male and the female flowers as widely as possible.

BLACK ALDER; WINTERBERRY FEVER-BUSH (Ilex verticillata) Holly family

Flowers - Small, greenish white, the staminate cl.u.s.ters 2 to 10 flowered the fertile ones 1 to 3 flowered. Stem: A shrub 6 to 25 ft. high. Leaves: Oval, tapering to a point, about 1 in. wide, saw-edged, dark green, smooth above, hairy, especially along veins underneath. Fruit: Bright red berries, about the size of a pea, apparently whorled around the twigs.

Preferred Habitat - Swamps, ditches, fencerows, and low thickets.

Flowering Season - June-July.

Distribution - Nova Scotia to Florida, west to Missouri.

Beautiful bright red berries, dotted or cl.u.s.tered along the naked twigs of the black alder, add an indispensable cheeriness to the somber winter landscape. Bunches of them, commonly sold in the city streets for household decoration, bring twenty-five cents each; hence the shrubs within a large radius of each market get ample pruning every autumn. The leaves turn black before dropping off.

The SMOOTH WINTERBERRY (I. laevigata), a similar species, but of more restricted range, ripens its larger, orange-red berries earlier than the preceding, and before its leaves, which turn yellow, not black, in autumn, have fallen. Another distinguis.h.i.+ng feature is that its small, greenish-white staminate flowers grow on long, very slender pedicels; whereas the solitary fertile flowers are much nearer the stern.

BITTERSWEET; WAX-WORK; STAFF-TREE (Celastrus scandens) Staff-tree family

Flowers - Small, greenish-white, 5-parted, some staminate, some pistillate only; in terminal compound racemes 4 in. long or less.

Stem: Woody, twining. Leaves: Alternate, oval, tapering, finely toothed, thin, with a tendency to show white variations. Fruit: A yellow-orange berry-like capsule, splitting at maturity and curling back to display the scarlet, pulpy coating of the seeds within.

Preferred Habitat - Rich soil of thickets, fence rows, and wayslde tangles.

Flowering Season - June.

Distribution - North Carolina, New Mexico, and far north.

Not to be hung above mirror and picture frames in farmhouse parlors, as we have been wont to think, do the brilliant cl.u.s.ters of orange-red wax-work berries attract the eye, where they brighten old walls, copses, and fence rows in autumn; but to advertise their charming wares to hungry migrating birds, which will drop the seeds concealed within the red berry perhaps a thousand miles away, and so plant new colonies. On the smaller, less specialized bees and flies the vine depends in June to carry pollen from its staminate flowers to the fertile ones, whose thick, erect pistil would wither without fruiting without their help.

But the best laid plans of other creatures than mice and men "gang aft a-gley." What mean the little cottony tufts all along the stems of so very many bittersweet vines, but that these have foes as well as friends? Curious little parasitic tree-hoppers (Membracis binotata), which spend their entire lives on the stems, sucking the juices through their little beaks, just as the aphids moor themselves to the tender rose-twigs, might be mistaken for thorns during one of their protective masquerades.

Again they look like diminutive flocks of fowl, their heads ever pointing in one direction, no matter how the vine may twist and turn - always toward the top of the branch, that they may the better siphon the sap down their tiny throats. Toward the end of summer the females, which have a sharp instrument at the rear of their bodies, cut deeply into the juicy food-store, the cambium layer of bark, and there deposit their eggs. Presently, a nest being filled, the mother emits a substantial froth at the end of her ovipositor, and proceeds to construct the cottony, corrugated dome over her nursery which first attracted our attention. This is especially skilful work, for she works behind her, evidently not from sight, but from instinct only. Inasmuch as the young hoppers will not come forth until the following summer, some such snug protection is required during winter's cold and snows. With hordes of little parasites constantly preying on its juices, is it any wonder the vine is often too enfeebled to produce seed, or that the leaves lose part of their color and become, as we say, variegated? Occasionally one finds the cottony nursery domes of this little hopper on the locust tree - the favorite home of its big, noisy relative, the so-called locust, or cicada.

NEW JERSEY TEA; WILD s...o...b..LL; RED-ROOT (Ceanothus America.n.u.s) Buckthorn family

Flowers - Small, white, on white pedicels, crowded in dense, oblong, terminal cl.u.s.ters. Calyx white, hemispheric, 5-lobed; petals, hooded and long-clawed; 5 stamens with long filaments; style short, 3-cleft. Stems: Shrubby, 1 to 3 ft. high, usually several, from a deep reddish root. Leaves: Alternate, ovate-oblong, acute at tip, finely saw-edged, 3-nerved, on short petioles.

Preferred Habitat - Dry, open woods and thickets.

Flowering Season - May-July.

Distribution - Ontario south and west to the Gulf of Mexico.

Light, feathery cl.u.s.ters of white little flowers crowded on the twigs of this low shrub interested thrifty colonial housewives of Revolutionary days not at all; the tender, young, rusty, downy leaves were what they sought to dry as a subst.i.tute for imported tea. Doubtless the thought that they were thereby evading George the Third's tax and brewing patriotism in every kettleful added a sweetness to the homemade beverage that sugar itself could not impart. The American troops were glad enough to use New Jersey tea throughout the war. A nankeen or cinnamon-colored dye is made from the reddish root.

NORTHERN, WILD, FOX, or PLUM GRAPE (Vitis Labrusca) Grape family

Flowers - Greenish, small, deliciously fragrant, some staminate, some pistillate, rarely perfect; the fertile flowers in more compact panicles than the sterile ones. Stem: Climbing with the help of tendrils; woody, bark loose. Leaves: Large, rounded or lobed, toothed, rusty-hairy underneath, especially when young, each leathery leaf opposite a tendril or a flower cl.u.s.ter. Fruit: Cl.u.s.ters containing a few brownish, purple, musky-scented grapes, 3/4 in. across. Ripe, August-September.
