Chapter 33

The YELLOW or CELANDINE POPPY (Stylophorum diphyllum), with shining yellow flowers double the size of the greater celandine's, and similar pinnatifid leaves springing chiefly from the base, blooms even in March and through the spring in the Middle States and westward to Wisconsin and Missouri. Usually only one of the few terminal blossoms opens at a time, but in low, open woodlands it gleams like a miniature sun. Alas! that the glorious CALIFORNIA POPPY, so commonly grown in Eastern gardens (Eschscholtzia Californica), should confine itself to a limited range on the Pacific Coast. We have no true native poppies (Papaver) in America; such as are rarely to be seen in a wild state, have only locally escaped from cultivation.

GOLDEN CORYDALIS (Capnoides aureum; Corydalis aurea of Gray) Poppy family

Flowers - Bright yellow, about 1/2 in. long, with a spur half the length of the tubular corolla; irregular, lipped; each upheld by a little bract, mostly at a horizontal; borne in a terminal, short raceme. Stem: Smooth, 6 to 14 in. high, branching. Leaves: Finely dissected, decom pound, petioled. Fruit: Sickle-shaped, drooping pods, wavy lumped, and tipped with the style. Preferred Habitat - Woods, rocky banks. Flowering Season - March-May. Distribution - Minnesota to Nova Scotia and Pennsylvania.

A dainty little plant, next of kin to the pink corydalis (q.v.).

BLACK MUSTARD (Brassica nigra) Mustard family

Flowers - Bright yellow, fading pale, 1/4 to 1/2 in. across, 4-parted, in elongated racemes; quickly followed by narrow upright 4-sided pods about 1/2 in. long appressed against the stem. Stem: Erect, 2 to 7 ft. tall, branching. Leaves: Variously lobed and divided, finely toothed, the terminal lobe larger than the 2 to 4 side ones. Preferred Habitat - Roadsides, fields, neglected gardens. Flowering Season - June-November. Distribution - Common throughout our area; naturalized from Europe and Asia.

"The kingdom of heaven is like unto a grain of mustard seed, which a man took and sowed in his field which indeed is less than all seeds but when it is grown, it is greater than the herbs, and becometh a tree, so that the birds of the air come and lodge in the branches thereof."

Commentators differ as to which is the mustard of the parable - this common black mustard, or a rarer shrub-like tree (Salvadora Persica), with an equivalent Arabic name, a pungent odor, and a very small seed. Inasmuch as the mustard which is systematically planted for fodder by Old World farmers grows with the greatest luxuriance in Palestine, and the comparison between the size of its seed and the plant's great height was already proverbial in the East when Jesus used it, evidence strongly favors this wayside weed. Indeed, the late Dr. Royle, who endeavored to prove that it was the shrub that was referred to, finally found that it does not grow in Galilee.

Now, there are two species which furnish the most powerfully pungent condiment known to commerce; but the tiny dark brown seeds of the black mustard are sharper than the serpent's tooth, whereas the pale brown seeds of the WHITE MUSTARD, often mixed with them, are far more mild. The latter (Sinapis alba) is a similar, but more hairy, plant, with slightly larger yellow flowers. Its pods are constricted like a necklace between the seeds.

The coarse HEDGE MUSTARD (Sisymbrium officinale), with rigid, spreading branches, and spikes of tiny pale yellow flowers, quickly followed by awl-shaped pods that are closely appressed to the stem, abounds in waste places throughout our area. It blooms from May to November, like the next species.

Another common and most troublesome weed from Europe is the FIELD or CORN MUSTARD, CHARLOCK or FIELD KALE (Brassica arvensis; Sinapis arvensis of Gray) found in grain fields, gardens, rich waste lands, and rubbish heaps. The alternate leaves, which stand boldly out from the stem, are oval, coarsely saw-toothed, or the lower ones more irregular, and lobed at their bases, all rough to the touch, and conspicuously veined. The four-parted yellow flowers, measuring half an inch or more across, have six stamens (like the other members of this cross-bearing family), containing nectar at their bases. Two of them are shorter than the other four. Honey-bees, ever abundant, the brilliant Syrphidae flies which love yellow, and other small visitors after pollen and nectar, to obtain the latter insert their tongues between the stamens, and usually cross-fertilize the flowers. In stormy weather, when few insects fly, the anthers finally turn their pollen-covered tips upward; then, by a curvature of the tip of the stamens, they are brought in contact with the flower's own stigma; for it is obviously better that even self-fertilized seed should be set than none at all. (See Ladies'-smock.) "The birds of the air" may not lodge in the charlock's few and feeble branches; nevertheless they come seeking the mild seeds in the strongly nerved, smooth pods that spread in a loose raceme. Domestic pigeons eat the seeds greedily.

The highly intelligent honey-bee, which usually confines itself to one species of plant on its flights, apparently does not know the difference between the field mustard and the WILD RADISH, or JOINTED or WHITE CHARLOCK (Raphanus Raphanistrum); or, knowing it, does not care to make distinctions, for it may be seen visiting these similar flowers indiscriminately. At first the blossoms of the radish are yellow, but they quickly fade to white, and their purplish veins become more conspicuous. Rarely the flowers are all purplish. The entire plant is rough to the touch; the leaves, similar to those of the garden radish, are deeply cleft (lyrate-pinnatifid); the seed pods, which soon follow the flowers up the spike, are nearly cylindric when fresh, but become constricted between the seeds, as they dry, until each little pod looks like a section of a bead necklace.

The GARDEN RADISH of the market (R. sativus), occasionally escaped from cultivation, although credited to China, is entirely unknown in its native state. "It has long been held in high esteem," wrote Peter Henderson, "and before the Christian era a volume was written on this plant alone. The ancient Greeks, in offering their oblations to Apollo, presented turnips in lead, beets in silver, and radishes in vessels of beaten gold." Pliny describes a radish eaten in Rome as being so transparent one might see through the root. It was not until the sixteenth century that the plant was introduced into England. Gerarde mentions cultivating four varieties for Queen Elizabeth in Lord Burleigh's garden.

The YELLOW ROCKET, HERB OF ST. BARBARA, YELLOW BITTER-CRESS, WINTER- or ROCKET-CRESS (Barbarca Barbarea; B. vulgaris of Gray) sends up spikes of little flowers like a yellow sweet alyssum as early as April, and continues in bloom through June. Smooth pods about one inch long quickly follow. The thickish, shining, tufted leaves, very like the familiar WATER-CRESS (Roripa Nasturtium), were formerly even more commonly eaten as a salad. In rich but dry soil the plant flourishes from Virginia far northward, locally in the interior of the United States and on the Pacific Coast.

WITCH-HAZEL (Hamamelis Virginiana) Witch-hazel family

Flowers - Yellow, fringy, clustered in the axils of branches. Calyx 4-parted; 4 very narrow curving petals about 34 in. long; 4 short stamens, also 4 that are scale-like; 2 styles. Stem: A tall, crooked shrub. Leaves: Broadly oval, thick, wavy-toothed, mostly fallen at flowering time. Fruit: Woody capsules maturing the next season and remaining with flowers of the succeeding year (Hama = together with; mela = fruit). Preferred Habitat - Moist woods or thickets near streams. Flowering Season - August-December. Distribution - Nova Scotia and Minnesota, southward to the Gulf States.

To find a stray. apple blossom among the fruit in autumn, or an occasional violet deceived by caressing Indian Summer into thinking another spring has come, surprises no one; but when the witch-hazel bursts into bloom for the first time in November, as if it were April, its leafless twigs conspicuous in the gray woods with their clusters of spidery pale yellow flowers, we cannot but wonder with Edward Rowland Sill:

"Has time grown sleepy at his post And let the exiled Summer back? Or is it her regretful ghost, Or witchcraft of the almanac?"

Not to the blue gentian but to the witch-hazel should Bryant have addressed at least the first stanza of his familiar lines (See Fringed Gentian). The shrub doubtless gives the small bees and flies their last feast of the season in consideration of their services in transferring pollen from the staminate to the fertile flowers. Very slowly through the succeeding year the seeds within the woody capsules mature until, by the following autumn, when fresh flowers appear, they are ready to bombard the neighborhood after the violets' method, in the hope of landing in moist yielding soil far from the parent shrub to found a new colony. Just as a watermelon seed shoots from between the thumb and forefinger pinching it, so the large, bony, shining black, white-tipped witch-hazel seeds are discharged through the elastic rupture of their capsule whose walls pinch them out. To be suddenly hit in the face by such a missile brings no smile while the sting lasts. Witch-hazel twigs ripening indoors transform a peaceful living room into a defenseless target for light artillery practice.

Nowhere more than in the naming of wild flowers can we trace the homesickness of the early English colonists in America. Any plant even remotely resembling one they had known at home was given the dear familiar name. Now our witch-hazel, named for an English hazel tree of elm lineage, has similar leaves it is true, but likeness stops there; nevertheless, all the folklore clustered about that mystic tree has been imported here with the title. By the help of the hazel's divining-rod the location of hidden springs of water, precious ore, treasure, and thieves may be revealed, according to old superstition. Cornish miners, who live in a land so plentifully stored with tin and copper lodes they can have had little difficulty in locating seams of ore with or without a hazel rod, scarcely ever sink a shaft except by its direction.

The literature of Europe is filled with allusions to it. Swift wrote:

"They tell us something strange and odd About a certain magic rod That, bending down its top divines Where'er the soil has hidden mines Where there are none, it stands erect Scorning to show the least respect."

A good story is told on Linnaeus in Baring-Gould's "Curious Myths of the Middle Ages": "When the great botanist was on one of his voyages, hearing his secretary highly extol the virtues of his divining-wand, he was willing to convince him of its insufficiency, and for that purpose concealed a purse of one hundred ducats under a ranunculus, which grew by itself in a meadow, and bid the secretary find it if he could. The wand discovered nothing, and Linnaeus's mark was soon trampled down by the company present, so that when he went to finish the experiment by fetching the gold himself, he was utterly at a loss where to find it. The man with the wand assisted him, and informed him that it could not lie in the way they were going, but quite the contrary so they pursued the direction of the wand, and actually dug out the gold. Linnaeus said that another such experiment would be sufficient to make a proselyte of him."

Many a well has been dug even in this land of liberty where our witch-hazel indicated; but here its kindly magic is directed chiefly through the soothing extract distilled from its juices.

FIVE-FINGER; COMMON CINQUEFOIL (Potentilla Canadensis) Rose family

Flowers - Yellow, 1/4 to 1/2 in. across, growing singly on long peduncles from the leaf axils. Five petals longer than the 5 acute calyx lobes with 5 linear bracts between them; about 20 stamens; pistils numerous, forming a head. Stem: Spreading over ground by slender runners or ascending. Leaves: 5-fingered, the digitate, saw-edged leaflets (rarely 3 or 4) spreading from a common point, petioled; some in a tuft at base. Preferred Habitat - Dry fields, roadsides, hills, banks. Flowering Season - April-August. Distribution - Quebec to Georgia, and westward beyond the Mississippi.

Everyone crossing dry fields in the eastern United States and Canada at least must have trod on a carpet of cinquefoil (cinque = five, feuilles = leaves), and have noticed the bright little blossoms among the pretty foliage, possibly mistaking the plant for its cousin, the trefoliate barren strawberry (q.v.). Both have flowers like miniature wild yellow roses. During the Middle Ages, when misdirected zeal credited almost any plant with healing virtues for every ill that flesh is heir to, the cinquefoils were considered most potent remedies, hence their generic name.

The SHRUBBY CINQUEFOIL, or PRAIRIE WEED (P. fructicosa), becomes fairly troublesome in certain parts of its range, which extends from Greenland to Alaska, and southward to New Jersey, Arizona, and California; as well as over northern Europe and Asia. It is a bushy, much branched, and leafy shrub, six inches to four feet high), with bright yellow, five-parted flowers an inch across, more or less, either solitary or in cymes at the tips of the branches. They appear from June to September. The honeybee, alighting in the center of a blossom and turning around, passes its tongue over the entire nectar-bearing ring at the base of the stamens, then proceeding to another flower to do likewise, effects cross-fertilization regularly. On a sunny day the bright blossoms attract many visitors of the lower grade out after nectar and pollen, the beetles often devouring the anthers in their greed. The leaves on this cinquefoil are usually compounded of one terminal and four side leaflets that are narrowly oblong, an inch or less in length, and silky hairy. Sometimes there may be seven leaflets pinnately, not digitately, arranged. Although the shrubby cinquefoil prefers swamps and moist, rocky places to dwell in, it wisely adapts itself, as globe-trotters should, to whatever conditions it meets.

SILVERY or HOARY CINQUEFOIL (P. argentea), found in dry soil, blooming from May to September from Canada to Delaware, Indiana, Kansas, and Dakota, also in Europe and Asia, has yellow flowers only about a quarter of an inch across, but foliage of special beauty. From the tufted, branching, ascending stems, four to twelve inches long, the finely cleft, five-foliate leaves are spread on foot stems that diminish in size as they ascend, not to let the upper leaves shut off the light from the lower ones. These leaves are smooth and green above, silvery on the under side, with fine white hairs, adapted for protection from excessive sunlight and too rapid transpiration of precious moisture. They entirely conceal the sensitive epidermis from which they grow.

YELLOW AVENS; FIELD AVENS (Geum strictum) Rose family

Flowers - Golden yellow, otherwise much resembling the lower growing white avens (q.v.). Preferred Habitat - Low ground, moist meadows, swamps. Flowering Season - June-August. Distribution - Pennsylvania, Missouri, and Arizona, far northward.

After the marsh marigolds have withdrawn their brightness from low-lying meadows, blossoms of yellow avens twinkle in their stead. In autumn the jointed, barbed styles, protruding from the seed clusters, steal a ride by the same successful method of travel to new colonizing ground adopted by burdocks, goose-grass, tick-trefoils (q.v.), agrimony, and a score of other "tramps of the vegetable world."

TALL or HAIRY AGRIMONY (Agrimonia hirsuta; Eupatoria of Gray) Rose family

Flowers - Yellow, small, 5-parted, in narrow, spike-like racemes. Stem: Usua11y 3 to 4 ft. tall, sometimes less or more clothed, with long, soft hairs. Leaves: Large, thin, bright green, compounded of (mostly) 7 principal oblong, coarsely saw-edged leaflets, with pairs of tiny leaflets between. Preferred Habitat - Woods, thickets, edges of fields. Flowering Season - June-August. Distribution - North Carolina, westward to California, and far north.

Quite a different species, not found in this country, is the common European Agrimony - A. Eupatoria of Linnaeus - which figures so prominently in the writings of medieval herbalists as a cure-all. Slender spires of green fruit below and yellow flowers above curve and bend at the borders of woodlands here apparently for no better reason than to enjoy life. Very few insects visit them, owing to the absence of nectar - certainly not the highly specialized and intelligent "Humble-Bee," to whom Emerson addressed the lines:

"Succory to match the sky, Columbine with horn of honey, Scented fern and agrimony, Clover, catch-fly, adder's-tongue, And brier-roses, dwelt among."

It is true the bumblebee may dwell among almost any flowers, but he has decided preferences for such showy ones as have adapted themselves to please his love of certain colors (not yellow), or have secreted nectar so deeply hidden from the mob that his long tongue may find plenty preserved when he calls. Occasional visitors alighting on the agrimony for pollen may distribute some, but the little blossoms chiefly fertilize themselves. When crushed they give forth a faint, pleasant odor. Pretty, nodding seed urns, encircled with a rim of hooks, grapple the clothing of man or beast passing their way, in the hope of dropping off in a suitable place to found another colony.

SENSITIVE PEA; WILD or SMALL-FLOWERED SENSITIVE PLANT (Cassia nictitans) Senna family

Flowers - Yellow, regular, 5-parted, about 1/4 in. across; 2 or 3 together in the axils. Stem: Weak, 6 to 15 in. tall, branching, leafy. Leaves: Alternate, sensitive, compounded of 12 to 44 small, narrowly oblong leaflets; a cup-shaped gland below lowest pair; stipules persistent. Fruit: A pod, an inch long or more, containing numerous seeds. Preferred Habitat - Dry fields, sandy wasteland, roadsides. Flowering Season - July-October. Distribution - New England westward to Indiana, south to Georgia and Texas.

How many of us ever pause to test the sensitiveness of this exquisite foliage that borders the roadsides, and in appearance is almost identical with the South American sensitive plant's, so commonly cultivated in hothouses here? Failing to see its fine little leaflets fold together instantly when brushed with the hand, as they do in the tropical species (Mimosa pudica), many pass on, concluding its title a misnomer. By simply touching the leaves, however roughly, only a tardy and slight movement follows. A sharp blow produces quicker effect, while if the whole plant be shaken by forcibly snapping the stem with the finger, all the leaves will be strongly affected; their sensitiveness being apparently more aroused by vibration through jarring than by contact with foreign bodies. The leaves, which ordinarily spread out flat, partly close in bright sunshine and "go to sleep" at night, not to expose their sensitive upper surfaces to fierce heat in the first case, and to cold by radiation in the second. "Lifeless things may be moved or acted on," says Asa Gray; "living beings move and act - plants less conspicuously, but no less really than animals. In sharing the mysterious gift of life they share some of its simpler powers."

The PARTRIDGE PEA or LARGE-FLOWERED SENSITIVE PLANT (C. Chamaecrista) likewise goes to sleep; the ten to fifteen pairs of leaflets which, with a terminal one, make up each pinnate leaf, slowly turning their outer edges uppermost after sunset, and overlapping as they flatten themselves against their common stem until the entire aspect of the plant is changed. By day the expanded foliage is feathery, fine, acacia-like; at night the bushy, branching, spreading plant, that measures only a foot or two high, appears to produce nothing but pods. These leaves respond slowly to vibration, just as the sensitive pea's do. In spite of their names, neither produces the butterfly-shaped (papilionaceous) blossom of true peas. The partridge pea bears from two to four showy flowers together, each measuring an inch or more across, on a slender pedicel from the axils. It fully expands only four of its five bright yellow petals; they are somewhat unequal in size, the upper ones, with touches of red at the base, as pathfinders, not, however, as nectar-guides, since no sweets are secreted here. Curiously enough, both right and left hand flowers are found upon the same plant; that is to say, the sickle-shaped pistil turns either to the right or the left. One lateral petal, instead of being flexible and spread like the rest, stands so stiffly erect and incurved that it commonly breaks on being bent back. Why? The pistil, it will be noticed, points away from the ten long black anthers. Obviously, then, the flower cannot fertilize itself. Its benefactors are bumblebee females and workers out after pollen. Cup-shaped nectaries ("extra nuptial") are situated on the upper side and near the base of the leaf stalks on these cassia plants, where they can have no direct influence on the fertilization of the blossoms. Apparently, they are free lunch-counters, kept open out of pure charity. Landing upon the long black anthers with pores in their tips to let out the pollen, the bumblebees "seize them between their mandibles, says Professor Robertson, "and stroke them downward with a sort of milking motion. The pollen...falls either directly upon the bee or upon the erect lateral petal which is pressed close against the bee's side. In this way the side of the bee which is next to the incurved petal receives the most pollen.... A bee visiting a left-hand flower receives pollen upon the right side, and then flying to a right-hand flower, strikes the same side against the stigma." When we find circular holes in these petals we may know the leaf-cutter or upholsterer bee (Megachile brevis) has been at work collecting roofs for her nurseries (see Hairy Ruellia). The partridge pea, which has a more westerly range than the sensitive pea's, extends it southward even to Bolivia. Game birds, migrants and rovers, which feed upon the seeds, have of course helped in their wider distribution. The plant blooms from July to September.

WILD or AMERICAN SENNA (Cassia Marylandica) Senna family

Flowers - Yellow, about 3/4 in. broad, numerous, in short axillary clusters on the upper part of plant. Calyx of 5 oblong lobes; 5 petals, 3 forming an upper lip, 2 a lower one; 10 stamens of 3 different kinds; 1 pistil. Stem: 3 to 8 ft. high, little branched. Leaves: Alternate, pinnately compounded of 6 to 10 pairs of oblong leaflets. Fruit: A narrow, flat curving pod, 3 to 4 in. long. Preferred Habitat - Alluvial or moist, rich soil, swamps, roadsides. Flowering Season - July-August. Distribution - New England, westward to Nebraska, south to the Gulf States.

Whoever has seen certain Long Island roadsides bordered with wild senna, the brilliant flower clusters contrasted with the deep green of the beautiful foliage, knows that no effect produced by art along the drives of public park or private garden can match these country lanes in simple charm. Bumblebees, buzzing about the blossoms, may be observed "milking" the anthers just as they do those of the partridge pea. No red spots on any of these petals guide the visitors, as in the previous species, however; for do not the three small, dark stamens, which are reduced to mere scales, answer every purpose as pathfinders here? The stigma, turned sometimes to the right, sometimes to the left, strikes the bee on the side; the senna being what Delpino, the Italian botanist, calls a pleurotribe flower.
