Wild Flowers Part 1

Wild Flowers.

PREFACE

Surely a foreword of explanation is called for from one who has the temerity to offer a surfeited public still another book on wild flowers. Inasmuch as science has proved that almost every blossom in the world is everything it is because of its necessity to attract insect friends or to repel its foes - its form, mechanism, color, markings, odor, time of opening and closing, and its season of blooming being the result of natural selection by that special insect upon which each depends more or less absolutely for help in perpetuating its species - it seems fully time that the vitally important and interesting relationship existing between our common wild flowers and their winged benefactors should be presented in a popular book.

Is it enough to know merely the name of the flower you meet in the meadow? The blossom has an inner meaning, hopes and fears that inspire its brief existence, a scheme of salvation for its species in the struggle for survival that it has been slowly perfecting with some insect's help through the ages. It is not a pa.s.sive thing to be admired by human eyes, nor does it waste its sweetness on the desert air. It is a sentient being, impelled to act intelligently through the same strong desires that animate us, and endowed with certain powers differing only in degree, but not in kind, from those of the animal creation. Desire ever creates form.

Do you doubt it? Then study the mechanism of one of our common orchids or milkweeds that are adjusted with such marvelous delicacy to the length of a bee's tongue or of a b.u.t.terfly's leg; learn why so many flowers have sticky calices or protective hairs; why the skunk cabbage, purple trillium, and carrion flower emit a fetid odor while other flowers, especially the white or pale yellow night bloomers, charm with their delicious breath; see if you cannot discover why the immigrant daisy already whitens our fields with descendants as numerous as the sands of the seash.o.r.e, whereas you may tramp a whole day without finding a single native ladies' slipper. What of the sundew that not only catches insects, but secretes gastric juice to digest them? What of the bladderwort, in whose inflated traps tiny crustaceans are imprisoned, or the pitcher plant, that makes soup of its guests?

Why are gnats and flies seen about certain flowers, bees, b.u.t.terflies, moths or humming birds about others, each visitor choosing the restaurant most to his liking? With what infinite pains the wants of each guest are catered to! How relentlessly are pilferers punished! The endless devices of the more ambitious flowers to save their species from degeneracy by close inbreeding through fertilization with their own pollen, alone prove the operation of Mind through them. How plants travel, how they send seeds abroad in the world to found new colonies, might be studied with profit by Anglo-Saxon expansionists. Do vice and virtue exist side by side in the vegetable world also? Yes, and every sinner is branded as surely as was Cain. The dodder, Indian pipe, broomrape and beech-drops wear the floral equivalent of the striped suit and the shaved head. Although claiming most respectable and exalted kinsfolk, they are degenerates not far above the fungi. In short, this is a universe that we live in; and all that share the One Life are one in essence, for natural law is spiritual law. "Through Nature to G.o.d," flowers show a way to the scientist lacking faith.

Although it has been stated by evolutionists for many years that in order to know the flowers, their insect relationships must first be understood, it is believed that "Nature's Garden" is the first American work to explain them in any considerable number of species. Dr. Asa Gray, William Hamilton Gibson, Clarence Moores Weed, and Miss Maud Going in their delightful books or lectures have shown the interdependence of a score or more of different blossoms and their insect visitors. Hidden away in the proceedings of scientific societies' technical papers are the invaluable observations of such men as Dr. William Trelease of Wisconsin and Professor Charles Robertson of Illinois. To the latter especially, I am glad to acknowledge my indebtedness.

Sprengel, Darwin, Muller, Delpino, and Lubbock, among others, have given the world cla.s.sical volumes on European flora only, but showing a vast array of facts which the theory of adaptation to insects alone correlates and explains. That the results of illumining researches should be so slow in enlightening the popular mind can be due only to the technical, scientific language used in setting them forth, language as foreign to the average reader as Chinese, and not to be deciphered by the average student either, without the help of a glossary. These writings, as well as the vast array of popular books - too many for individual mention - have been freely consulted after studies made afield.

To Sprengel belongs the glory of first exalting flowers above the level of botanical specimens. After studying the wild geranium he became convinced, as he wrote in 1787, that "the wise Author of Nature has not made even a single hair without a definite design.

A hundred years before, one, Nehemias Grew, had said that it was necessary for pollen to reach the stigma of a flower in order that it might set fertile seed, and Linnaeus bad to come to his rescue with conclusive evidence to convince a doubting world that he was right. Sprengel made the next step forward, but his writings lay neglected over seventy years because he advanced the then incredible and only partially true statement that a flower is fertilized by insects which carry its pollen from its anthers to its stigma. In spite of his discoveries that the hairs within the wild geranium protect its nectar from rain for the insect benefactor's benefit; that most flowers which secrete nectar have what he termed "honey guides" - spots of bright color, heavy veining, or some such pathfinder for the visitor on the petals; that sometimes the male flowers, the staminate ones, are separated from the seed-bearing or pistillate ones on distinct plants, he left it to Darwin to show that cross-fertilization by insects, the transfer of pollen from one blossom to another - not from anthers to stigma of the same flower - is the great end to which so much marvelous floral mechanism is adapted. The wind is a wasteful, uncertain pollen distributor. Insects transfer it more economically, especially the more highly organized and industrious ones. In a few instances hummingbirds, as well, unwittingly do the flower's bidding while they feast now here, now there. In spite of Sprengel's most patient and scientific research, that shed great light on the theory of natural selection a half century before Darwin advanced it, he never knew that flowers are nearly always sterile to pollen of another species when carried to them on the bodies of insect visitors, or that cross-pollenized blossoms defeat the self-pollinated ones in the struggle for survival. These facts Darwin proved in endless experiments.

Because bees depend absolutely upon flowers, not only for their own food but for that of future generations for whom they labor; because they are the most diligent of all visitors, and are rarely diverted from one species of flower to another while on their rounds collecting, as they must, both nectar and pollen, it follows they are the most important fertilizing agents. It is estimated that, should they perish, more than half the flowers in the world would be exterminated with them! Australian farmers imported clover from Europe, and although they had luxuriant fields of it, no seed was set for next year's planting, because they had failed to import the b.u.mblebee. After his arrival, their loss was speedily made good.

Ages before men cultivated gardens, they had tiny helpers they knew not of. Gardeners win all the glory of producing a Lawson pink or a new chrysanthemum; but only for a few seasons do they select, hybridize, according to their own rules of taste. They take up the work where insects left it off after countless centuries of toil. Thus it is to the night-flying moth, long of tongue, keen of scent, that we are indebted for the deep, white, fragrant Easter lily, for example, and not to the florist; albeit the moth is in his turn indebted to the lily for the length of his tongue and his keen nerves: neither could have advanced without the other. What long vistas through the ages of creation does not this interdependence of flowers and insects open!

Over five hundred flowers in this book have been cla.s.sified according to color, because it is believed that the novice, with no knowledge of botany whatever, can most readily identify the specimen found afield by this method, which has the added advantage of being the simple one adopted by the higher insects ages before books were written. Technicalities have been avoided in the text wherever possible, not to discourage the beginner from entering upon one of the most enjoyable and elevating branches of Nature study. The scientific names and cla.s.sification follow that method adopted by the International Botanical Congress which has now superseded all others; nevertheless the t.i.tles employed by Gray, with which older botanists in this country are familiar, are also indicated where they differ from the new nomenclature.

NELTJE BLANCHAN, New York, March, 1900

"Let us content ourselves no longer with being mere 'botanists' - historians of structural facts. The flowers are not mere comely or curious vegetable creations, with colors, odors, petals, stamens and innumerable technical attributes. The wonted insight alike of scientist, philosopher, theologian, and dreamer is now repudiated in the new revelation. Beauty is not 'its own excuse for being,' nor was fragrance ever 'wasted on the desert air.'

The seer has at last heard and interpreted the voice in the wilderness. The flower is no longer a simple pa.s.sive victim in the busy bee's sweet pillage, but rather a conscious being, with hopes, aspirations and companionships. The insect is its counterpart. Its fragrance is but a perfumed whisper of welcome, its color is as the wooing blush and rosy lip, its portals are decked for his coming, and its sweet hospitalities humored to his tarrying; and as it speeds its parting affinity, rests content that its life's consummation has been fulfilled." - William Hamilton Gibson.

"I often think, when working over my plants, of what Linnaeus once said of the unfolding of a blossom: 'I saw G.o.d in His glory pa.s.sing near me, and bowed my head in worship.' The scientific aspect of the same thought has been put into words by Tennyson:

'Flower in the crannied wall I pluck you out of the crannies, I hold you here, root and all in my hand Little flower, - but if I could understand What you are, root and all, and all in all, I should know what G.o.d and man is.'

No deeper thought was ever uttered by poet. For in this world of plants, which, with its magician, chlorophyll, conjuring with sunbeams, is ceaselessly at work bringing life out of death, - in this quiet vegetable world we may find the elementary principles of all life in almost visible operation." - JOHN FISKE in "Through Nature to G.o.d."

FROM BLUE TO PURPLE FLOWERS

"If blue is the favorite color of bees, and if bees have so much to do with the origin of flowers, how is it that there are so few blue ones? I believe the explanation to be that all blue flowers have descended from ancestors in which the flowers were green; or, to speak more precisely, in which the leaves surrounding the stamens and pistil were green; and that they have pa.s.sed through stages of white or yellow, and generally red, before becoming blue." - Sir John Lubbock in "Ants, Bees, and Wasps."

VIRGINIA or COMMON DAY-FLOWER (Commelina Virginica) Spiderwort family

Flowers - Blue, 1 in. broad or less, irregular, grouped at end of stem, and upheld by long leaf-like bracts. Calyx of 3 unequal sepals; 3 petals, 1 inconspicuous, 2 showy, rounded. Perfect stamens 3; the anther of 1 incurved stamen largest; 3 insignificant and sterile stamens; 1 pistil. Stem: Fleshy, smooth, branched, mucilaginous. Leaves: Lance-shaped, 3 to 5 in.

long, sheathing the stem at base; upper leaves in a spathe-like bract folding like a hood about flowers. Fruit: A 3-celled capsule, seed in each cell.

Preferred Habitat - Moist, shady ground.

Flowering Season - June - September.

Distribution - Southern New York to Illinois and Michigan, Nebraska, Texas, and through tropical America to Paraguay. - Britton and Browne.

Delightful Linnaeus, who dearly loved his little joke, himself confesses to have named the day-flowers after three brothers Commelyn, Dutch botanists, because two of them - commemorated in the two showy blue petals of the blossom - published their works; the third, lacking application and ambition, amounted to nothing, like the inconspicuous whitish third petal! Happily Kaspar Commelyn died in 1731, before the joke was perpetrated in "Species Plantarum."

In the morning we find the day-flower open and alert-looking, owing to the sharp, erect bracts that give it support; after noon, or as soon as it has been fertilized by the female bees, that are its chief benefactors while collecting its abundant pollen, the lovely petals roll up, never to open again, and quickly wilt into a wet, shapeless ma.s.s, which, if we touch it, leaves a sticky blue fluid on our finger-tips.

The SLENDER DAY-FLOWER (C. erecta), the next of kin, a more fragile-looking, smaller-flowered, and narrower-leafed species, blooms from August to October, from Pennsylvania southward to tropical America and westward to Texas.

SPIDERWORT; WIDOW'S or JOB'S TEARS (Tradescantia Virginiana) Spiderwort family

Flowers - Purplish blue, rarely white, showy, ephemeral, 1 to 2 in. broad; usually several flowers, but more drooping buds, cl.u.s.tered and seated between long blade-like bracts at end of stern. Calyx of 3 sepals, much longer than capsule. Corolla of 3 regular petals; 6 fertile stamens, bearded; anthers orange; 1 pistil. Stem: 8 in. to 3 ft. tall, fleshy, erect, mucilaginous, leafy. Leaves: Opposite, long, blade-like, keeled, clasping, or sheathing stem at base. Fruit: 3-celled capsule.

Preferred Habitat - Rich, moist woods, thickets, gardens.

Flowering Season - May-August.

Distribution - New York and Virginia westward to South Dakota and Arkansas.

As so very many of our blue flowers are merely naturalized immigrants from Europe, it is well to know we have sent to England at least one native that was considered fit to adorn the grounds of Hampton Court. John Tradescant, gardener to Charles I, for whom the plant and its kin were named, had seeds sent him by a relative in the Virginia colony; and before long the deep azure blossoms with their golden anthers were seen in gardens on both sides of the Atlantic - another one of the many instances where the possibilities of our wild flowers under cultivation had to be first pointed out to us by Europeans.

Like its relative the dayflower, the spiderwort opens for part of a day only. In the morning it is wide awake and pert; early in the afternoon its petals have begun to retreat within the calyx, until presently they become "dissolved in tears," like Job or the traditional widow. What was flower only a few hours ago is now a fluid jelly that trickles at the touch. Tomorrow fresh buds will open, and a continuous succession of bloom may be relied upon for a long season. Since its stigma is widely separated from the anthers and surpa.s.ses them, it is probable the flower cannot fertilize itself, but is wholly dependent on the female bees and other insects that come to it for pollen. Note the hairs on the stamens provided as footholds for the bees.

The plant is a cousin of the "Wandering Jew" (T. repens), so commonly grown either in water or earth in American sitting-rooms. In a shady lane within New York city limits, where a few stems were thrown out one spring about five years ago, the entire bank is now covered with the vine, that has rooted by its hairy joints, and, in spite of frosts and blizzards, continues to bear its true-blue flowers throughout the summer.

PICKEREL WEED (Pontederia cordata) Pickerel-weed family

Flowers - Bright purplish blue, including filaments, anthers, and style; crowded in a dense spike; quickly fading; unpleasantly odorous. Perianth tubular, 2-lipped, parted into 6 irregular lobes, free from ovary; middle lobe of upper lip with 2 yellow spots at base within. Stamens 6, placed at unequal distances on tube, 3 opposite each lip. Pistil 1, the stigma minutely toothed.

Stem: Erect, stout, fleshy, to 4 ft. tall, not often over 2 ft.

above water line. Leaves: Several bract-like, sheathing stem at base; leaf only, midway on flower-stalk, thick, polished, triangular, or arrow-shaped, 4 to 8 in. long, 2 to 6 in. across base.

Preferred Habitat - Shallow water of ponds and streams.

Flowering Season - June-October.

Distribution - Eastern half of United States and Canada.

Grace of habit and the bright beauty of its long blue spikes of ragged flowers above rich, glossy leaves give a charm to this vigorous wader. Backwoodsmen will tell you that pickerels lay their eggs among the leaves; but so they do among the sedges, arums, wild rice, and various aquatic plants, like many another fish. Bees and flies, that congregate about the blossoms to feed, may sometimes fly too low, and so give a plausible reason for the pickerel's choice of haunt. Each blossom lasts but a single day; the upper portion, withering, leaves the base of the perianth to harden about the ovary and protect the solitary seed. But as the gradually lengthened spike keeps up an uninterrupted succession of bloom for months, more than ample provision is made for the perpetuation of the race - a necessity to any plant that refuses to thrive unless it stands in water. Ponds and streams have an unpleasant habit of drying up in summer, and often the pickerel weed looks as brown as a bulrush where it is stranded in the baked mud in August. When seed falls on such ground, if indeed it germinates at all, the young plant naturally withers away.

In the Bulletin of the Torrey Botanical Club, Mr. W. H. Leggett, who made a careful study of the flower, tells that three forms occur, not on the same, but on different plants, being even more distinctly trimorphic than the purple Loosestrife. As these flowers set no seed without insects' aid, the provisions made to secure the greatest benefit from their visits are marvelous. Of the three kinds of blossoms, one raises its stigma on a long style reaching to the top of the flower; a second form lifts its stigma only halfway up, and the third keeps its stigma in the bottom of the tube. Now, there are two sets of stamens, three in each set bearing pollen grains of different size and value.

Whenever the stigma is high, the two sets of stamens keep out of its way by occupying the lowest and middle positions, or just where the stigmas occur in the two other forms; or, let us say, whenever the stigma is in one of the three positions, the different sets of stamens occupy the other two. In a long series of experiments on flowers occurring in two and three forms - dimorphic and trimorphic - Darwin proved that perfect fertility can be obtained only when the stigma in each form is pollenized with grains carried from the stamens of a corresponding height.

For example, a bee on entering the flower must get his abdomen dusted with pollen from the long stamens, his chest covered from the middle-length stamens, and his tongue and chin from the set in the bottom of the tube nearest the nectary. When he flies off to visit another flower, these parts of his body coming in contact with the stigmas that occupy precisely the position where the stamens were in other individuals, he necessarily brushes off each lot of pollen just where it will do the most good. Pollen brought from high stamens, for example, to a low stigma, even should it reach it, which is scarcely likely, takes little or no effect. Thus cross-fertilization is absolutely essential, and in three-formed flowers there are two chances to one of securing it.

WILD HYACINTH, SCILLA or SQUILL. QUAMASH (Quamasia kyacinthina; Scilla Fraseri of Gray) Lily family

Flowers - Several or many, pale violet blue, or rarely white, in a long, loose raceme; perianth of 6 equal, narrowly oblong, widely spreading divisions, the thread-like filaments inserted at their bases; style thread-like, with 3-lobed stigma. Scape: 1 to 2 ft. high, from egg-shaped, nearly black bulb, 1 to 1 1/2 in.

long. Leaves: Gra.s.s-like, shorter than flowering scape, from the base. Fruit: A 3-angled, oval capsule containing shining black seeds.

Preferred Habitat - Meadows, prairies, and along banks of streams.

Flowering Season - April-May.

Distribution - Pennsylvania and Ohio westward to Minnesota, south to Alabama and Texas.
