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 im- portant 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 per fecting with some insect’s help through the ages. It is not a pas- 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 mar- vellous delicacy to the length of a bee’s tongue or of a butterfly’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 seashore, 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 impris- oned, or the pitcher-plant, that makes soup of its guests? Why are gnats and flies seen about certain flowers, bees, butterflies, Vv Preface 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, broom-rape, 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 God,” 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 tha 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, | am glad to acknowledge my indebted- ness. Sprengel, Darwin, Miller, Delpino, and Lubbock, among others, have given the world classical 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 their illumining researches should be so slow in enlight- ening the popular mind can be due only to the technical, scien- tific 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 a aa mention—have been freely consulted after studies made afield. To Sprengel belongs the glory of first exalting flowers above the level of mere botanical specimens. After studying the wild geranium he became convinced, ashe wrote in 1787, that ‘‘the wise Author of Nature has not made even a single hair without a defi- nite design.” A hundred years before, one, Nehemias Grew, had said that it was necessary for pollen to reach the stigma of a flowet vi Preface in order that it might set fertile seed, and Linnaeus had 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 ade vanced the then incredible and only partially true statement that a flower is fertilized by insects which carry its pollen from its ane thers to itsstigma. In spite of his discoveries that the hairs within the wild geranium protect its nectar from rain for the insect bene= factor’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 some- times 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 marvellous 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 humming birds, as well, Snel do the flower’s bidding while they feast now here, now there. In spite of Sprengel’s most pa- tient 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 an- other 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 ailisent 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 fol- lows 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 bumblebee. 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 fora 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 cen- turies 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 vii Preface 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 inter dependence of flowers and insects open ! Over five hundred flowers in this book have been classified according to color, because it is believed that the novice, with no knowledge of botany whatever, can most Seat identify the specimen found afield by this method, which has the added ad- vantage 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 classification follow that method adopted by the International Botanical Congress which has now superseded all others; nevertheless the titles employed by Gray, with which older botanists in this country are familiar, are also indicated where they differ from the new nomenclature. Mr. Dugmore’s very beautiful photographs in color from the living flowers, and the no less exquisite portraits from life in black and white by Mr. Troth, cannot but prove the most attrace tive, as they are the most useful, feature of this book.

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 ts now repudiated in the new revelation. Beauty és 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 passive victim in the busy bee's sweet pillage, but rather a conscious being, with hopes, aspirations and companionships, The insectisits counterpart. Its fragrance ts but a perfumed whisper of welcome, its color is as the wooing blush and rosy kip, its portals are decked for his coming, and its sweet hospitalities humored 20 his tarrying ; and as tt speeds its parting affinity, rests content that tts Hfe’s consummation has been fufilled."—WittuaM Hamittos Gyss0n, “ I often think, when working over my plants, of what Linnaeus once said of the unfolding of a blossom: ‘1 saw God in His glory passing 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 L pluck you out of the crannies, L hold you here, root and all, in my hand Little flower,—but if [ could understand What you are, root and ail, and allin all, L should know what God and man is.’ NVo deeper thought was ever uttered by poet. For in this world of plants, which, with its magician, chlorophyl, conjuring with sunbeams, is cease- lessly at work bringing hfe out of death,—in this quiet vegetable world we may find the elementary principles of all life in almost visible operation.” —Joun Fiske in “ Through Nature to God.” FROM BLUE TO PURPLE FLOWERS “ Uf blue is the favourite colour 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? f 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 passed through stages of white or yellow, and generally red, before becoming blue.’ —SiR JOHN LUBBOCK in “Ants, Bees, and Wasps.” FROM BLUE TO PURPLE FLOWERS 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, 2showy, rounded. Perfect stamens 3 ; the anther of 1 incurved stamen largest ; 3 insig- nificant 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, 1 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 Para- guay.”—Britton and Browne. Delightful Linnzeus, who dearly loved his little joke, himself confesses to have named the day-flowers after three brothers Commelyn, Dutch botanists, because two of them—commemo- rated 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 per- petrated 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 mass, 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-leaved species, blooms from August to October, from Pennsylvania southward to tropical America and westward to Texas. 3 From Blue to Purple 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, clustered and seated between long blade-like bracts at end of stem. 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 man instances where the possibilities of our wild flowers under culti- vation had to be first pointed out to us by Europeans. Like its relative the day-flower, 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. To-morrow fresh buds will open, and a continuous succession of bloom may be relied upon for a long season. Since its stigma is widely sep- arated from the anthers and surpasses 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. 4 From Blue to Purple Pickerel Weed (Pontederia cordata) Pickerel-weed family Flowers—Bright es day blue, including filaments, anthers, and style ; crowded in a dense spike ; quickly fading ; unpleas- antly odorous. Perianth tubular, 2-lipped, parted into 6 irreg- ular 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, 1 to 4 ft. tall, not often over 2 ft. above water line. Leaves: Several bract- like, sheathing stem at base ; 1 leaf only, midway on flower- stalk, thick, polished, triangular, or arrow-shaped, 4 to 8 in., long, 2 to 6 in. across base: (Illustration, facing p. 20.) Lreferred 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 suc- cession 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 bullrush 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. Leg- gett, 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 marvellous. 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 half-way up, and the third keeps its stigma in the bottom of 5 From Blue to Purple 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 sta- mens occupy the other two. _In a long series of experiments on flowers occurring in two and three forms—dimorphic and tri- morphic—Darwin proved that perfect fertility can be obtained only when the stigma in each form is pollenized with grains car- ried 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 bot- tom 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 hyacinthina) Lily family (Scilla Fraseri of Gray) 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% in. long. Leaves: Grass-like, shorter than flowering scape, from the base. Fruit: A 3-angled, oval capsule cone taining 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. Coming with the crocuses, before the snow is off the ground, and remaining long after their regal gold and purple chalices have withered, the Siberian scillas sold by seedsmen here deserve a place in every garden, for their porcelain-blue color is rare as it is 6 From Blue to Purple charming; the early date when they bloom makes them espe- cially welcome; and, once planted and left undisturbed, the bulbs increase rapidly, without injury from overcrowding. Evidently they need little encouragement to run wild. Nevertheless they are not wild scillas, however commonly they may be miscalled so. Certainly ladies’ tresses, known as wild hyacinth in parts of New England, has even less right to the name. Our true native wild hyacinth, or scilla, is quite a different flower, not so pure a blue as the Siberian scilla, and paler; yet in the middle West, where it abounds, there are few lovelier sights in spring than a colony of these blossoms directed obliquely upward from slender, swaying scapes among the lush grass. heir upward slant brings the stigma in immediate contact with an incoming visitor’s pollen-laden body. As the stamens diverge with the spreading of the divisions of the perianth, to which they are attached, the stigma receives pollen brought from another flower, before the visitor dusts himself anew in searching for re- freshment, thus effecting cross-pollination. Ants, bees, wasps, flies, butterflies, and beetles may be seen about the wild hyacinth, which is obviously best adapted to the bees. The smallest in- sects that visit it may possibly defeat Nature’s plan and obtain nectar without fertilizing the flower, owing to the wide passage between stamens and stigma. In about an hour, one May morn- ing, Professor Charles Robertson captured over six hundred in- sects, representing thirty-eight distinct species, on a patch of wild hyacinths in Illinois. The bulb of a Mediterranean Scilla (S. maritima) furnishes the sou sweet syrup of squills used in medicine for bronchial troubles. The Grape Hyacinth (Muscari botryoides), also known as Baby’s Breath, because of its delicate faint fragrance, escapes from gardens at slight encouragement to grow wild in the roadsides and meadows from Massachusetts to Virginia and westward to Ohio. Its tiny, deep-blue, globular flowers, stiffly set around a fleshy scape that rises between erect, blade-like, channeled leaves, appear spring after spring wherever the small bulbs have been planted. On the east end of Long Island there are certain mead- ows literally blued with the little runaways. Purple Trillium, Ill-scented Wake-Robin, or Birth-root (Trillium erectum) Lily-of-the-Valley family } Flowers—Solitary, dark, dull purple, or purplish red ; rarely green« ish, white, or pinkish ; on erect or slightly inclined footstalk. 7 From Blue to Purple Calyx of 3 spreading sepals, 1 to 134 in. long, or about length of 3 pointed, oval petals ; stamens 6; anthers longer than filaments ; pistil spreading into 3 short, recurved stigmas. Stem: Stout, 8 to 16 in. high, from tuber-like rootstock. Leaves : In a whorl of 3; broadly ovate, abruptly pointed, netted-veined. Fruit: A 6-angled, ovate, reddish berry. Preferred Habitat—Rich, moist woods. Flowering Season—April—June. Distribution—Nova Scotia westward to Manitoba, southward to North Carolina and Missouri. Some weeks after the jubilant, alert robins have returned from the South, the purple trillium unfurls its unattractive, car- rion-scented flower. In the variable colors found in different regions, one can almost trace its evolution from green, white, and red to purple, which, we are told, is the course all flowers must follow to attain to blue. The’white and pink forms, however attractive to the eye, are never more agreeable to the nose than the reddish-purple ones. Bees and butterflies, with delicate ap- preciation of color and fragrance, let the blossom alone, since it secretes no nectar; and one would naturally infer either that it can fertilize itself without insect aid—a theory which closer study - of its organs goes far to disprove—or that the carrion-scent, so repellent to us, is in itself an attraction to certain insects need- ful for cross-pollination. Which are they? Beetles have been observed crawling over the flower, but without effecting any methodical result. One inclines to accept Mr. Clarence M. Weed’s theory of special adaptation to the common green flesh- flies (Lucilia carnicina), which would naturally be attracted to a flower resembling in color and odor a raw beefsteak of uncertain age. These little creatures, seen in every butcher shop through- out the summer, the flower furnishes with a free lunch of pollen in consideration of the transportation of a few grains to another blossom. Absence of the usual floral attractions gives the carrion flies a practical monopoly of the pollen food, which no doubt tastes as it smells. The Sessile-flowered Wake-Robin (7. sessile), whose dark purple, purplish-red, or greenish blossom, narrower of sepal and petals than the preceding, is seated in a whorl of three egg shaped, sometimes blotched, leaves, possesses a rather pleasant odor; nevertheless it seems to have no great attraction for insects. The stigmas, which are very large, almost touch the anthers surrounding them ; therefore the beetles which one fre- quently sees crawling over them to feed on the pollen so jar them, no doubt, as to self-fertilize the flower ; but it is scarcely pee these slow crawlers often transfer the grains from one lossom to another. A degraded flower like this has little need of 8 From Blue to Purple color and perfume, one would suppose ; yet it may be even now slowly perfecting its way toward an ideal of which we see a part only complete. In deep, rich, moist woods and thickets the ses- sile trillium blooms in April or May, from Pennsylvania, Ohio, and Minnesota southward nearly to the Gulf. Larger Blue Flag; Blue Iris; Fleur-de-lis; Flower-de-luce (/ris versicolor) Iris family Flowers—Several, 2 to 3 in. long, violet-blue variegated with yellow, green, or white, and purple veined. Six divisions of the peri- anth: Asses ones spreading, recurved; 1 of them bearded, much longer and wider than the 3 erect inner divisions ; all united into a short tube. Three stamens under 3 overhang- ing petal-like divisions of the style, notched at end; under each notch is a thin plate, smooth on one side, rough and moist (stigma) on side turned away from anther. Stem: 2 to ft. high, stout, straight, almost circular, sometimes branch~ ing above. Leaves: Erect, sword-shaped, shorter than stem, somewhat hoary, from % to 1 in. wide, folded, and in a _ compact flat cluster at base; bracts usually longer than stem _ of flower. Fruit: Oblong capsule, not prominently 3-lobed, % and with 2 rows of round, flat seeds closely packed in each cell. | ‘Rootstock: Creeping, horizontal, fleshy. Preferred Habitat—Marshes, wet meadows. Flowering Season—May—J uly. casa a and Manitoba to Arkansas and orida. ‘The fleur-de-lys, which is the flower of chivalry,” says Ruskin, ‘‘has a sword for its leaf and a lily for its heart.””, When that young and pious Crusader, Louis VII., adopted it for the emblem of his house, spelling was scarcely an exact science, and the fleur-de-Louzs soon became corrupted into its present form. Doubtless the royal flower was the white iris, and as /z is the Celtic for white, there is room for another theory as to the origin of the name. It is our far more regal looking, but truly demo- cratic blossom, jostling its fellows in the marshes, that is indeed **born in the purple.” When Napoleon wished to pose as the true successor of those ancient French kings whose territory included the half of Europe—ignoring every Louis who ever sat on the throne, for their very name and emblem had become odious to the people— he discarded the fleur-de-lis, to replace it with golden bees, 9 From Blue to Purple the symbol in armory for industry and perseverance. It is said some relics of gold and fine stones, somewhat resembling an insect in shape, had been found in the tomb of Clovis’s father, and on the supposition that these had been bees, Napoleon appro- priated them for the imperial badge. Henceforth ‘‘ Napoleonic bees” appeared on his coronation robe and wherever a heraldic emblem could be employed. But even in the meadows of France Napoleon need not have looked far from the fleurs-de-lis growing there to find bees. Indeed, this gorgeous flower is thought by scientists to be all that it is for the bees’ benefit, which, of course, is its own also. Abundant moisture, from which to manufacture nectar—a prime necessity with most irises—certainly is for our blue flag. The large showy blossom cannot but attract the passing bee, whose favorite color (according to Sir John Lubbock) it waves. The bee alights on the convenient, spreading platform, and, guided by the dark veining and golden lines leading to the nectar, sips the delectable fluid shortly to be changed to honey. Now, as he raises his head and withdraws it from the nectary, he must rub it against the pollen-laden anther above, and some of the pollen necessarily falls on the visitor. As the sticky side of the plate (stigma), just under the petal-like division of the style, faces away from the anther, which is below it in any case, the flower is marvellously guarded against fertilization from its own pollen. The bee, flying off to another iris, must first brush past the projecting lip of the over-arching style, and leave on the stigmatic outer surface of the plate some of the pollen brought from the first flower, before reaching the nectary. Thus cross-fertilization is effected; and Darwin has shown how necessary this is to insure the most vigor- ous and beautiful offspring. Without this wonderful adaptation of the flower to the requirements of its insect friends, and of the insect to the needs of the flower, both must perish; the former from hunger, the latter because unable to perpetuate its race. And yet man has greedily appropriated all the beauties of the floral kingdom as designed for his sole delight ! The name iris, meaning a deified rainbow, which was given this group of plants by the ancients, shows a fine appreciation of their superb coloring, their ethereal texture, and the evanescent beauty of the blossom. In spite of the name given to another species, the Southern Blue Flag (/. hexagona) is really the larger one ; its leaves, which are bright green, and never hoary, often equalling the stem in its height of from two to three feet. The handsome solitary flower, similar to that of the larger blue flag, nevertheless has its broad outer divisions fully an inch larger, and is seated in the axils at the top of the circular stem. The oblong, cylindric, six-angled capsule also contains two rows of seeds in each cavity. From Io From Blue to Purple South Carolina and Florida to Kentucky, Missouri, and Texas one finds this iris blooming in the swamps during April and May. The Slender Blue Flag (/. prismatica) (I. Virginica of Gray), found growing from New Brunswick to North Carolina, but mainly ‘near the coast, and often in the same oozy ground with the larger blue flag, may be known by its grass-like leaves, two or three of which usually branch out from the slender flexuous stem ; by its solitary or two blue flowers, variegated with white and veined with yellow, that rear themselves on slender foot-stems ; and by the sharply three-angled, narrow, oblong capsule, in which but one row of seeds is borne in each cavity. This is the most graceful member of a rather stiffly stately family. Pointed Blue-eyed Grass; Eye-bright; Blue Star (Sisyrinchium angustifolium) Iris family Flowers—From blue to purple, with a yellow centre ; a Western variety, white ; usually several buds at the end of stem, between 2 erect unequal bracts; about % in. across; perianth of 6 spreading divisions, each pointed with a bristle from a notch ; stamens 3, the filaments united to above the middle ; pistil 1, its tip 3-cleft. Stem: 3 to 14 in. tall, pale hoary green, flat, rigid, 2-edged. Leaves: Grass-like, pale, rigid, mostly from base. Fruzt: 3-celled capsule, nearly globose. Preferred Habitat—Moist fields and meadows. Flowering Season—May—August. Distribution—Newfoundland to British Columbia, from eastern slope of Rocky Mountains to Atlantic, south to Virginia and Kansas. Only for a day, and that must be a bright one, will this ‘‘little sister of the stately blue flag’ open its eyes, to close them in in- dignation on being picked ; nor will any coaxing but the sun- shine’s induce it to open them again in water, immediately after. The dainty flower, growing in dense tufts, makes up in numbers what it lacks in size and lasting power, flecking our meadows with purplish ultramarine blue in a sunny June morning. Later in the day, apparently there are no blossoms there, for all are tightly closed; never to bloom again. New buds will unfold to tinge the field on the morrow. : Usually three buds nod from between a pair of bracts, the lower one of which may be twice the length of the upper one ; but only one flower opens at a time. Slight variations in this plant have been considered sufficient to differentiate several species formerly included by Gray and other American botanists under the name of S. Bermudiana. i From Blue to Purple Large, or Early, Purple-fringed Orchis (Habenaria grandiflora) Orchid family (H. fimbriata of Gray) Flowers—Pink-purple and pale lilac, sometimes nearly white ; fragrant, alternate, clustered in thick, dense spikes from 3 to 15 in. long. Upper sepal and toothed petals erect; the lip of deepest shade, % in. long, fan-shaped, 3-parted, fringed half its length, and prolonged at base into slender, long spur; stamen united with style into short column; 2 anther sacs slightly divergent, the hollow between them glutinous, stigmatic. Stem. 1 to 5 ft. high, angled, twisted. Leaves: Oval, large, sheathing the stem below; smaller, lance-shaped ones higher up; bracts above. Root: Thick, fibrous. Preferred Habitat—Rich, moist meadows, muddy places, woods. Flowering Season-—June—August. Distribution—New Brunswick to Ontario; southward to North Carolina, westward to Michigan. Because of the singular and exquisitely unerring adaptations of orchids as a family to their insect visitors, no group of plants has greater interest for the botanist since Darwin interpreted their marvellous mechanism, and Gray, his instant disciple, revealed the hidden purposes of our native American species, no less wonderfully constructed than the most costly exotic in a millionaire’s hothouse. A glance at the spur of this orchid, one of the handsomest and most striking of its clan, and the heavy perfume of the flower, would seem to indicate that only a moth with a long proboscis could reach the nectar secreted at the base of the thread-like passage. Butterflies, attracted by the conspicuous color, sometimes hover about the showy spikes of bloom, but it is probable that, to secure a sip, all but possibly the very largest vf them must go to the smaller purple-fringed orchis, whose shorter spur holds out a certain prospect of reward; for, in these two cases, as in so many others, the flower’s welcome for an insect is in exact proportion to the length of its visitor’s tongue. Doubtless it is one of the smaller sphinx moths, such as we see at dusk working about the evening primrose and other flowers deep of chalice, and heavily perfumed to guide visitors to their feast, that is the great purple-fringed orchid’s benefactor, since the length of its tongue is perfectly adapted to its needs. At- tracted by the showy, broad lower petal, his wings ever in rapid motion, the moth proceeds to unroll his proboscis and drain the cup, that is frequently an inch and a half deep. Thrusting in his head, 12 we From Blue to Purple either one or both of his large, projecting eyes are pressed against the sticky button-shaped disks to which the pollen masses are attached by a stalk, and as he raises his head to depart, feeling that he is caught, he gives a little jerk that detaches them, and away he flies with these still fastened to his eyes. Even while he is flying to another flower, that is to say, in half a minute, the stalks of the pollen masses bend downward from the perpendicular and slightly toward the centre, or just far enough to require the moth, in thrusting his probosis into the nectary, to strike the glutinous, sticky stigma. Now, withdraw- ing his head, either or both of the golden clubs he brought in with him will be left on the precise spot where they will fertilize the flower. Sometimes, but rarely, we catcha butterfly or moth from the smaller or larger purple orchids with a pollen mass attached to his tongue, instead of to his eyes; this is when he does not make his entrance from the exact centre—as in these flowers he is not obliged to do—and in order to reach the nectary his tongue necessarily brushes against one of the sticky anther sacs. The performance may be successfully imitated by thrust- ing some blunt point about the size of ‘a moth’s head, a dull pen- cil or a knitting-needle, into the flower as an insect would enter. Withdraw the pencil, and one or both of the pollen masses will be found sticking to it, and already automatically changing their attitude. In the case of the large, round-leaved orchis, whose greenish-white flowers are fertilized in a similar manner by the sphinx moth, the anther sacs converge, like little horns; and their change of attitude while they are being carried to fer- tilize another flower is quite as exquisitely exact. Usually in wetter ground than we find its more beautiful big sister growing in, most frequently in swamps and bogs, the Smaller Purple-fringed Orchis (H. psycodes) lifts its perfumed lilac spires. Thither go the butterflies and long-lipped bees to feast in July and August. Inasmuch as without their aid the orchid must perish from its inability to set fertile seed, no wonder it woos its benefactors with a showy mass of color, charming fringes, sweet perfume, and copious draughts of nectar, and makes their visits of the utmost value to itself by the ingenious mechanism described above. Here is no waste of pollen; that is snugly packed in little bundles, ready to be carried off, but placed where they cannot come in contact with the adjoining stigma, since every orchid, almost without exception, refuses to be deteriorated through self-fertilization. From New Jersey and Illinois southward, particularly in mountainous regions, if not among the mountains themselves, the Fringeless Purple Orchis (H. peramoena) may be found bloom- ing in moist meadows through July and August. Moisture, from 13 From Blue to Purple which to manufacture the nectar that orchids rely upon so largely to entice insects to work for them, is naturally a prime necessity ; yet Sprengel attempted to prove that many orchids are gaudy shams and produce no nectar, but exist by an organized system of deception. ‘‘ Scheinsaftblumen” he called them. From the number of butterflies seen hovering about this fringeless orchis and its more attractive kin, it is small wonder their nectaries are soon exhausted and they are accused of being gay deceivers. Sprengel’s much-quoted theory would credit moths, butterflies, and even the highly intelligent bees with scant sense; but Dar- win, who thoroughly tested it, forever exonerated these insects from imputed stupidity and the flowers from gross dishonesty. He found that many European orchids secrete their nectar between the outer and inner walls of the tube, which a bumblebee can easily pierce, but where Sprengel never thought to look for it. The large lip of this orchis is not fringed, but has a fine picotée edge. The showy violet-purple, long-spurred flowers are alter- nately set on a stem that is doing its best if it reach a height of two and a half feet. Water-shield, or Water Target (Brasenia purpurea) Water-lily family (B. peltata of Gray) Flowers—Small, dull purplish, about ¥% in. across, on stout foote stalks from axils of upper leaves; 3 narrow sepals and petals; stamens 12 to 18; pistils 4 to 18, forming 1 to 3-seeded pods. Stem ; From submerged rootstock; slender, branching, several feet long, covered with clear jelly, as are footstalks and lower leaf surfaces. Leaves: On long petioles attached to centre of under side of leaf, floating or rising, oval to roundish, 2 to 4 in. long, 134 to 2 in. wide. Preferred Habitat—Still, rather deep water of ponds and slow streams. Flowering Season—All summer. Distribution—Parts of Asia, Africa, and Australia, Nova Scotia to Cuba, and westward from California to Puget Sound. Of this pretty water plant Dr. Abbott says, in ‘‘ Wasteland Wanderings”: ‘‘I gathered a number of floating, delicate leaves, and endeavored to secure the entire stem also; but this was too difficult a task for an August afternoon. The under side of the stem and leaf are purplish brown and were covered with trans- lucent jelly, embedded in which were millions of what I took to be insects’ eggs. They certainly had that appearance. I was 14 From Blue to Purple far more interested to find that, usually, beneath each leaf there was hiding a little pike. The largest was not two inches in length. When disturbed, they swam a few inches, and seemed wholly ‘at sea’ if there was not another leaf near by to afford them shelter.” European, or Common Garden, Columbine (Aquilegia vulgaris) Crowfoot family Flowers—Showy, blue, purple, or white, 114 to 2 in. broad, or about as broad as long ; spurs stout and strongly incurved. General characteristics of plant resembling wild columbine. Preferred Habitat—Escaped from gardens to woods and fields in Eastern and Middle States. Native of Europe. Flowering Season—May—July. A heavier, less graceful flower than either the wild red and yellow columbine or the exquisite, long-spurred, blue and white species (A. caerulea) of the Rocky Mountain region; nevertheless this European immigrant, now making itself at home here, is a charming addition to our flora. How are insects to reach the well of nectar secreted in the tip of its incurved, hooked spur? Certain of the long-lipped bees, large bumble-bees, whose tongues have developed as rapidly as the flower, are able to drain it. Humming-birds, partial to red flowers, fertilize the wild colum-: bine, but let this one alone. Muller watched a female bumblebee making several vain attempts to sip this blue one. Soon the bril- liant idea of biting a hole through each spur flashed through her little brain, and the first experiment proving delightfully success- ful, she proceeded to bite holes through other flowers without first trying to suck them. Apparently she satisfied her feminine con- science with the reflection that the flower which made dining so difficult for its benefactors deserved no better treatment. Field, or Branched, Larkspur; Knight’s-spur3 Lark-heel (Delphinium Consolida) Crowfoot family Flowers—Blue to pinkish and whitish, 1 to 1% in. long, hung on slender stems, and scattered along spreading branches; 5 petal-like sepals, the rear one prolonged into long, slender, curving spur; 2 petals, united. Stem: 1 to 2% ft. high.. Leaves; Divided into very finely cut linear segments, 15 From Blue to Purple Fruit: Erect, smooth pod tipped with a short beak; open on one side. Preferred Habitat—Roadsides and fields. Flowering Season—June—August. Distribution—Naturalized from Europe; from New Jersey south- ward, occasionally escaped from gardens farther north. Keats should certainly have extolled the larkspurs in his sonnet on blue. No more beautiful group of plants contributes to the charm of gardens, woods, and roadsides, where some have escaped cultivation and become naturalized, than the delphinium, that take their name from a fancied resemblance to a dolphin (del~ phin), given them by Linnzeus in one of his wild flights of imagina~ tion. Having lost the power to fertilize themselves, according to Miller, they are pollenized by both bees and butterflies, insects whose tongues have kept pace with the development of certain flowers, such as the larkspur, columbine, and violet, that they may reach into the deep recesses of the spurs where the nectar is hidden from all but benefactors. The Tall Wild Larkspur (D. urceolatum, or D. exaltatum of Gray) waves long, crowded, downy wands of intense purplish blue in the rich woods of Western Pennsylvania, southward to the Carolinas and Alabama, and westward to Nebraska. Its spur is nearly straight, not to increase the difficulty a bee must have in pressing his lips through the upper and lower petals to reach the nectar at the end of it. First, the stamens successively raise them- selves in the passage back of the petals to dust his head; then, when each has shed its pollen and bent down again, the pistil takes its turn in occupying the place, so that a pollen-laden bee, coming to visit the blossom from an earlier flower, can scarcely help fertilizing it. It is said there are but two insects in Europe with lips long enough to reach the bottom of the long horn of plenty hung by the Bee Larkspur (D. e/atum), that we know only in gardens here. Its yellowish bearded lower petals readily de- ceive one into thinking a bee has just alighted there. From April to June the Dwarf Larkspur or Stagger-weed (D. tricorne), which, however, may sometimes grow three feet high, lifts a loose raceme of blue, rarely white, flowers an inch or more long, at the end of a stout stem rising from a tuberous root. Its slightly ascending spur, its three widely spreading seed vessels, and the deeply cut leaf of from five to seven divisions are distinguishing characteristics. From Western Pennsylvania and Georgia to Arkansas and Minnesota it is found in rather stiff soil. Butterflies, which prefer erect flowers, have some difficulty to cling while they drain the almost upright spurs, especially the Papilios, which usually suck with their wings in motion. But the bees, to 16 From Blue to Purple ‘which the delphinium are best adapted, although butterflies visit them quite as frequently, find a convenient landing place prepared for them, and fertilize the flower while they sip with ease. More slender, downy, and dwarf of stem than the preceding is the Carolina Larkspur (D. Carolinianum), whose blue flowers, varying to white, and its very finely cleft leaves, may be found in the South, on prairies in the North and West, and in the Rocky Mountain region. Liver-leaf; Hepatica; Liverwort; Round- lobed, or Kidney Liver-leaf; Noble Liver- wort; Squirrel Cup (Hepatica Hepatica) Crowfoot family (H. triloba of Gray) Even under the snow itself bravely blooms the delicate hepatica, wrapped in fuzzy furs as if to protect its stems and nod- ding buds from cold. After the plebeian skunk cabbage, that ought scarcely to be reckoned among true flowers—and William Hamilton Gibson claimed even before it—it is the first blossom to appear. Winter sunshine, warming the hillsides and edges of woods, opens its eyes, ** Blue as the heaven it gazes at, Startling the loiterer in the naked groves With unexpected beauty ; for the time Of blossoms and green leavés is yet afar.” s 17 from Stue vo Purpfe ‘‘ There are many things left for May,” says John Burroughs, ‘‘but nothing fairer, if as fair, as the first flower, the hepatica. i find I have never admired this little firstling half enough. When at the maturity of its charms, it is certainly the gem of the woods. What an individuality it has! No two clusters alike; all shades and sizes. . . . A Solitary blue-purple one, fully expanded and rising over the brown leaves or the green moss, its cluster of minute anthers showing like a group of pale stars on its little firmament, is enough to arrest and hold the dullest eye. Then, . . . there are individual hepaticas, or individual fami- lies among them, that are sweet scented. The gift seems as capricious as the gift of genius in families. You cannot tell which the fragrant ones are till you try them. Sometimes it is the large white ones, sometimes the large purple ones, sometimes the small pink ones. The odor is faint, and recalls that of the sweet violets. A correspondent, who seems to. have carefully observed these fragrant hepaticas, writes me that this gift of odor is constant in the same plant; that the plant which bears sweet- scented flowers this year will bear them next.” It is not evident that insect aid is necessary to transfer the tiny, hairy spiral ejected from each cell of the antherid, after it has burst from ripeness, to the canal of the flask-shaped organ at whose base the germ-cell is located. Perfect flowers can fertilize themselves. But pollen-feeding flies, and female hive bees which collect it,.and the earliest butterflies trifle about the blossoms when the first warm days come, Whether they are rewarded by finding nectar or notis still a mooted question. Possibly the papillze which cover the receptacle secrete nectar, for almost without exception the insect visitors thrust their proboscides down between the spreading filaments as if certain of asip. None merely feed on the pollen except the flies and the hive bee. oe The Sharp-lobed Liver-leaf (Hepatica acuta) differs chiefly from the preceding in having the ends of the lobes of its leaves and the tips of the three leaflets that form its involucre. quite sharply pointed. Its range, while perhaps ‘not actually’ more westerly, appears so, since it is rare in the East, where its cousin is so abundant; and common in the West, where the round-lobed liver-leaf is scarce. It blooms in March and April. Professor Halsted has noted that this species bears staminate flowers on one plant and pistillate flowers on another; whereas the Hepatica Hepatica usually bears flowers of both sexes above the same root. The blossoms, which close at night to keep warm, and open in the morning, remain on the beautiful plant for a long time to ace commodate the bees and flies that, in this case, are essential to the perpetuation of the species, From Blue to Purple Purple Virgin’s Bower (Atragene Americana) Crowfoot family Flowers—Showy, purplish blue, about 3 in. across; 4 sepals, broadly expanded, thin, translucent, strongly veined, very large, simu- lating petals ; petals small, spoon-shaped ; stamens very nu- merous ; styles long, persistent, plumed throughout. Stem: Trailing or partly climbing with the help of leafstalks and leaflets. Leaves: Opposite, compounded of 3 egg-shaped, pointed leaflets on slender petioles. Preferred Habitat—Rocky woodlands. Flowering Season—May—June. Distribution—Hudson Bay westward, south to Minnesota and Virginia. The day on which one finds this rare and beautiful flower in some rocky ravine high among the hills or mountains becomes memorable to the budding botanist. At an elevation of three thousand feet in the Catskills it trails its way over the rocks, fallen trees, and undergrowth of the forest, suggesting some of the handsome Japanese species introduced by Sieboldt and For- tune to Occidental gardens. No one who sees this broadly ex- panded blossom could confuse it either with the thick and bell- shaped purple Leather-flower (C. Viorna), so exquisitely feathery in fruit, that grows in rich, moist soil from Pennsylvania south- ward and westward; or with the far more graceful and deliciously fragrant purple Marsh Clematis (C. créspa) of our Southern States. The latter, though bell-shaped also, has thin, recurved sepals, and its persistent styles are silky, not feathery at seed-time. Orpine; Live-forever; Midsummer-Men; Live- long; Pudding-bag Plant; Garden Stone- crop; Witches’ Money (Sedum Telephium) Orpine family Flowers—Dull purplish, very pale or bright reddish purple in close, round, terminal clusters, each flower % in. or less across, 5- parted, the petals twice as long as the sepals; 10 stamens, alternate ones attached to petals; pistils 4or5. Stem: 2 ft. high or less, erect, simple, in tufts, very smooth, pale green, juicy, leafy. Leaves: Alternate, oval, slightly scalloped, thick, fleshy, smooth, juicy, pale gray green, with stout midrib, seated on stalk. 19 From Blue to Purple Preferred Habitat—Fields, waysides, rocky soil, originally escaped from gardens. Flowering Season—June—September. Distribution—Quebec westward, south to Michigan and Maryland, Children know the live-forever, not so well by the variable flower—for it is a niggardly bloomer—as by the thick leaf that they delight to hold in the mouth until, having loosened the mem- brane, they are able to inflate it like a paper bag. Sometimes dull, sometimes bright, the flower clusters never fail to attract many insects to their feast, which is accessible even to those of short tongues. Each blossom is perfect in itself, z.¢., it contains both stamens and pistils; but to guard against self-fertilization it ripens its anthers and sheds its pollen on the insects that carry it away to older flowers before its own stigmas mature and be- come susceptible to imported pollen. After the seed-cases take on color, they might be mistaken for blossoms. As if the plant did not already possess enough popular names, it needs must share with the European golden-rod and our com- mon mullein the title of Aaron’s rod. Sedere, to sit, the root of the generic name, applies with rare appropriateness to this entire group that we usually find seated on garden walls, rocks, or, in urope, even on the roofs of old buildings. Rooting freely from the joints, our plant forms thrifty tufts where there is little apparent nourishment; yet its endurance through prolonged drought is remarkable. Long after the farmer’s scythe, sweeping over the roadside, has laid it low, it thrives on the juices stored up in flesh leaves and stem until it proves its title to the most lusty of all folk names. Purple or Water Avens (Geum rivale) Rose family Flowers—Purple, with some orange chrome, 1 in. broad or less, terminal, solitary, nodding; calyx 5-lobed, purplish, spread- ing; 5 petals, abruptly narrowed into claws, forming a cup- shaped corolla; stamens and pistils of indefinite number; the styles, jointed and bent in middle, persistent, feathery below. Stem: 1 to 2 ft. high, erect, simple or nearly so, hairy, from thickish rootstock. Leaves: Chiefly from root, on footstems; lower leaves irregularly parted; the side segments usually few and small; the 1 to 3 terminal segments sharply, irregu- larly lobed; the few distant stem leaves 3-foliate or simple, mostly seated on stem. Fruit: A dry, hairy head stalked in calyx. Preferred Habitat—Swamps and low, wet ground. lowering Season—May—July. 20 From Blue to Purple Distribution—Newfoundland far westward, south to Colorado, : eastward to Missouri and Pennsylvania, also northern parts of Old World. Mischievous bumblebees, thrusting their long tongues be-' tween the sepals and petals of these unopened flowers, steal nec. tar without conferring any favor in return. Later, when they behave properly and put their heads inside to feast at the disk on which the stamens are inserted, they dutifully carry pollen from old flowers to the early maturing stigmas of younger ones. Self fertilization must occur, however, if the bees have not removed all the pollen when a blossom closes. When the purple avens opens in Europe, the bees desert even the primrose to feast upon its abundant nectar. Since water is the prime necessity in the manufacture of this sweet, and since insects that feed upon it have so much to do with the multiplication of flowers, it is not surpris- ing that the swamp, which has been called ‘‘ nature’s sanctuary,” should have its altars so exquisitely decked. This blossom hangs its head, partly to protect its precious nectar from rain, and partly to make pilfering well-nigh impossible to the unwelcome crawling insect that may have braved the forbidding hairy stems. Wild Lupine; Old Maid’s Bonnets; Wild Pea; Sun Dial (Lupinus perennis) Pea family Flowers—Vivid blue, very rarely pink or white, butterfly-shaped ; corolla consisting of standard, wings, and keel; about % in. long, borne in a long raceme at end of stem; calyx 2-lipped, deeply toothed. Stem: Erect, branching, leafy, 1 to 2 ft. high. Leaves; Palmate, compounded of from 7 to 11 (usually 8) leaflets. Fruit: A broad, flat, very hairy pod, 134 in. long, and containing 4 or 5 seeds. Preferred Habitat—Dry, sandy places, banks, and hillsides. Flowering Season—May—June. Distribution — United States east of Mississippi, and eastern Canada. Farmers once thought that this plant preyed upon the fertility of their soil, as we see in the derivation of its name, from lupus, a wolf; whereas the lupine contents itself with sterile waste land no one should grudge it—steep gravelly banks, railroad tracks, exposed sunny hills, where even it must often burn out under fierce sunshine did not its root penetrate to surprising depths. It spreads far and wide in thrifty colonies, reflecting the vivid color of June skies, until, as Thoreau says, ‘‘the earth is blued with it.” 21 From Blue to Purple What is the advantage gained in the pea-shaped blossom? As usual, the insect that fertilizes the flower best knows the answer. The corolla has five petals, the upper one called the standard, chiefly a flaunted advertisement; two side wings, or platforms, to alight on; and a keel like a miniature boat, formed by the two lower petals, whose edges meet. In this the pistil, stamens, and nectar are concealed and protected. The pressure of a bee’s weight as he alights on the wings, light as it must be, is nevertheless sufficient to depress and open the keel, which is elastically affected by their motion, and so to expose the pollen just where the long-lipped bee must rub off some against his under side as he sucks the nectar. He actually seems to pump the pollen that has fallen into the forward part of the keel upon him- self, as he moves about. As soon as he leaves the flower, the elastic wings resume their former position, thus closing the keel to prevent waste of pollen. Take a sweet pea from the garden, press down its wings with the thumb and forefinger to imitate the action of the bee on them; note how the keel opens to dis- play its treasures, and resumes its customary shape when the pressure is removed. The lupine is another of those interesting plants which go to sleep at night. Some members of the genus erect one half of the leaf and droop the other half until it becomes a vertical instead of the horizontal star it is by day. Frequently the leaflets rotate as much as go° on their own axes. Some lupines fold their leaf- lets, not at night only, but during the day also there is more or less movement in the leaves. Sun dial, a popular name for the wild lupine, has reference to this peculiarity. The leaf of our species shuts downward around its stem, umbrella fashion, or the leaflets are erected to prevent the chilling which comes to horizontal sure faces by radiation, some scientists think. ‘‘ That the sleep move- ments of leaves are in some manner of high importance to the plants which exhibit them,” says Darwin, ‘‘few will dispute who have observed how complex they sometimes are.” Canadian or Showy Tick-trefoil (Meibomia Canadensis) Pea family (Desmodium Canadense of Gray) Flowers—Pinkish or bluish purple, butterfly-shaped, about %-in. long, borne in dense, terminal, elongated racemes. Stem; Erect, hairy, leafy, 2 to 8 ft. high. Leaves: Compounded of 3 oblong leaflets, the central one largest; upper leaves nearly seated on stem; bracts, conspicuous before flowering, early falling off. Fruit: A flat pod, about 1 in. long, jointed, and 22 From Blue to Purple covered with minute hooked bristles, the lower edge of pod scalloped; almost seated in calyx. Preferred Habitat—Thickets, woods, river banks, bogs. Flowering Season—July—September. Distribution—New Brunswick to Northwest Territory, south to North Carolina, westward to Indian Territory and Dakota. As one travels hundreds or even thousands of miles in a comfortable railway carriage and sees the same flowers growing throughout the length and breadth of the area, one cannot but wonder how ever the plants manage to make the journey. We know some creep along the ground, or under it, a tortoise pace, but a winning one; that some send their offspring flying away from home, like dandelions and thistles; and many others with wings and darts are blown by the wind. Berries have their seeds dropped afar by birds. Aquatic plants and those that grow beside running water travel by river and flood. European species reach our shores among the ballast. Darwin raised over sixty wild plants from seed carried in a pellet of mud taken from the leg of a partridge. Soonandsoon. The imagination delights tc picture these floral vagabonds, each with its own clever method of getting a fresh Start in the world. But by none of these methods just mentioned do the tick-trefoils spread abroad. Theirs is indeed a by hook or by crook system. The scalloped, jointed pod, where the seeds lie concealed, has minute crooked bristles, which catch in the clothing of man or beast, so that every herd of sheep, every dog, every man, woman, or child who passes through a patch of tre~ foils gives them a lift. After a walk through the woods and lanes of late summer and autumn, one’s clothes reveal scores of tramps that have stolen a ride in the hope of being picked off and dropped amid better conditions in which to rear a family. Only the largest bees can easily ‘‘explode” the showy tick-/ trefoil. A humblebee alights upon a flower, thrusts his head under the base of the standard petal, and, forces apart the siti etals with his legs, in order to dislodge them from the standard. his motion causes the keel, also gonnected with the standard, to snap down violently, thus releasing the column within and send- ing upward an explosion of pollen on the under surface of the bee. Here we see the wing petals acting as triggers to discharge the flower. Depress them and up flies the fertilizing dust—once. The little gun will not ‘‘ go off” twice. No nectar rewards the visitor, which usually is a pollen-collecting bee. The highly in- telligent and important humblebee has the advantage over his smaller kin in being able to discharge the pollen from both large and smaller flowers. The Naked-flowered Tick-trefoil (M. nudiflora or D. nudi- Yorum of Gray) lifts narrow, few-flowered panicles of rose- 23 From Blue to Purple purple blooms during July and August. The flowers are much smaller than those of the showy trefoil; however, when seen in masses, they form conspicuous patches of color in dry woods. Note that there is a flower stalk which is usually leafless and also a leaf-bearing stem rising from the base of the plant, the latter with its leaves all crowded at the top, if you would distinguish this very common species from its multitudinous kin. The tre- foliate leaves are pale beneath. The two or three jointed pod rises far above the calyx on its own stalk, as in the next species. The Pointed-leaved Tick-trefoil (M. grandifiora, or D. acu minatum of Gray) has for its distinguishing feature a cluster of leaves high up on the same stem from which rises a stalk bearing a quantity of purple flowers that are large by comparison only. The leaves have leaflets from two to six inches long, rounded on the sides, but acutely pointed, and with scattered hairs above and below. This trefoil is found blooming in dry or rocky woods, throughout a wide range, from June to September. Lying outstretched for two to six feet on the dry ground of open woods and copses east of the Mississippi, the Prostrate Tick- trefoil (M. Michauxi or D. rotundtfolium of Gray) can certainly be named by its soft hairiness, the almost perfect roundness of its trefoliate leaves, its rather loose racemes of deep purple flows ers that spring both from the leaf axils and from the ends of the sometimes branching stem; and by its three to five jointed pod, which is deeply scalloped on its lower edge and somewhat in- dented above, as well. Blue, Tufted, or Cow Vetch or Tare; Cat Peas; Tinegrass (Vicia Cracca) Pea family Florucrs —Blue, later purple; % in. long, growing downward in 1-sided spike, 15 to 40 flowered; calyx oblique, small, with unequal teeth ; ccrolla butterfly-shaped, consisting of standard, wings, and keel, all oblong; the first clawed, the second oblique, and adhering to the shorter keel; 10 stamens, 1! detached from other 9. Stem: Slender, weak, climbing of trailing, downy, 2 to 4 ft. long. Leaves :- Tendril bearing, divided into 18 to 24 thin, narrow, oblong leaflets. Fruit: A smooth pod 1 in. long or less, 5 to 8 seeded. Preferred Habitat—Dry soil, fields, waste land. Flowering Season—June—August. Distribution—United States from New Jersey, Kentucky, and lowa northward and northwestward. Europe and Asia. 24 From Blue to Purple Dry fields blued with the bright blossoms of the tufted vetch, and roadsides and thickets where the angular vine sends forth vivid patches of color, resound with the music of happy bees. Al- though the parts of the flower fit closely together, they are elastic, and opening with the energetic visitor’s weight and movement give ready access to the nectary. On his departure they resume their original position, to protect both nectar and pollen from rain and pil- ferers whose bodies are not perfectly adapted to further the flower’s cross-fertilization. The common humblebee (Bombus terrestris) plays a mean trick, all too frequently, when he bites a hole at the base of the blossom, not only gaining easy access to the sweets for himself, but opening the way for others less intelligent than he, but quite ready to profit by his mischief, and so defeat nature’s plan. Dr. Ogle observed that the same bee always acts in the same manner, one sucking the nectar legitimately, another always biting a hole to obtain it surreptitiously, the natural inference, of course, being that some bees, like small boys, are naturally depraved. In cultivated fields and waste places farther south and west- ward to the Pacific Coast roams the Common or Pebble Vetch or Tare (V. sativa), another domesticated weed that has come to us from Europe, where it is extensively grown for fodder. Let no reproach fall on these innocent plants that bear an opprobrious name: the tare of Scripture is altogether different, the bearded darnel of Mediterranean regions, whose leaves deceive one by simulating those of wheat, and whose smaller seeds, instead of nourishing man, poison him. Only one or two light blue-purple flowers grow in the axils of the leaves of our common vetch. The leaf, compounded of from eight to fourteen leaflets, indented at the top, has a long terminal tendril, whose little sharp tip assists the awkward vine, like a grappling hook. The American Vetch, or Tare, or Pea Vine (V. Americana) boasts slightly larger bluish-purple flowers than the blue vetch, but fewer of them; from three to nine only forming its loose raceme. In moist soil throughout a very broad northerly and westerly range it climbs and trails its graceful way, with the help of the tendrils onthe tips of leaves compounded of from eight to fourteen oblong, blunt, and veiny leaflets. Beach, Sea, Seaside, or Everlasting Pea (Lathyrus maritimus) Pea family Flowers—Purple, butterfly-shaped, consisting of standard petal, wings, and keel; 1 in. long or less, clustered in short raceme at end of slender footstalk from leaf axils; calyx 5-toothed; 25 From Blue to Purple stamens 10 (9 and 1); style curved, flattened, bearded on inner side. Stem: 1 to 2 ft. long, stout, reclining, spreading, leafy. Leaves: Compounded of 3 to 6 pairs of oblong leaflets somewhat larger than halbert-shaped stipules at base of leaf; _ branched tendrils at end of it. Frudt: A flat, 2-valved, veiny pod, continuous between the seeds. Preferred Habitat—Beaches of Atlantic and Pacific veeans, also of Great Lakes. Flowering Season—May—August. Sometimes blooming again in autumn. Distribution—New Jersey to Arctic Circle ; also Northern Europe and Asia. Sturdy clumps of the beach pea, growing beyond reach of the tide in the dunes and sandy wastelands back of the beach, afford the bee the last restaurant where he may regale himself without fear of drowning. From some members of the pea fam- ily, as from the wild lupine, for example, his weight, as he moves ahont, actually pumps the pollen that has fallen into the forward part of the blossom’s keel onto his body, that he may transfer it to another flower. In some other members his weight so de- presses the keel that the stamens are forced out to dust him over, the flower resuming its original position to protect its nectar and the remaining pollen just as soon as the pressure is removed. Other peas, again, burst at his pressure, and discharge their pollen on him. Now, in the beach pea, and similarly in the vetches, the style is hairy on its inner side, to brush out the pollen on the visitor who sets the automatic sweeper in motion as he alights and moves about. So perfectly have many members of this in- teresting family adapted their structure to the requirements of insects, and so implicitly do they rely on their automatic mechan ism, that they have actually lost the power to fertilize themselves. In moist or wet ground throughout a northern range from ocean to ocean, the Marsh Vetchling (Lathyrus palustris) bears its purple, butterfly-shaped flowers, that are the merest trifle over half the size of those of the beach pea. From two to six of these little blossoms are alternately set along the end of the stalk. The leaflets, which are narrowly oblong, and acute at the apex, stand up opposite each other in pairs (from two to four) along the main leafstalk, that splits at the end to form hooked tendrils. Butterfly or Blue Pea (Ciitorta Mariana) Pea family Flowers—Bright lavender blue, showy, about 2 in. long; from ! to 3 borne ona short peduncle. Calyx tubular, 5-toothed; 26 From Blue to Purple corolla butterfly-shaped, consisting of very large, erect stand ard petal, notched at rounded apex; 2 oblong, curved wings, and shorter, acute keel; 10 stamens; style incurved, and hairy along inner side. Stem: Smooth, ascending or partly twin- ing, 1 to 3 ft. high. Leaves: Compounded of 3 oblong leaf- lets, paler beneath, each on short stalk. Fruit: A fewe seeded, acutely pointed pod about 1 in. long. Preferred Habitat—Dry soil. Flowering Season—June—July. Distribution—New Jersey to Florida, westward to Missouri, Texas, and Mexico, A beautiful blossom, flaunting a large banner out of all propor tion to the size of its other parts, that it may arrest the attention of its benefactors the bees. According to Henderson, the plant, which is found in our Southern States and over the Mexican border, grows also in the Khasia Mountains of India, but in no intervening lace. Several members of the tropic-loving genus, that produce arge, highly colored flowers, have been introduced to American hothouses; but the blue butterfly pea is our only native repre- sentative. The genus is thought to take its name from £/eio, to shut up, in reference to the habit these peas have of seeding long before the flower drops off. : Wild or Hog Peanut (Falcata comosa) Pea family (Amphicarpea monoica of Gray) Flowers—Numerous small, showy ones, borne in drooping clusters from axils of upper leaves; lilac, pale purplish, or rarely white, butterfly-shaped, consisting of standard petal partly enfolding wings and keel. Calyx tubular, 4 or 5 toothed; 10 stamens (9 and 1); 1 pistil. (Also solitary fertile flowers, lacking petals, on thread-like, creeping branches from lower axils or underground). Stem: Twining wiry brownish-hairy, 1 to 8 ft. long. Leaves : Compounded of 3 thin leaflets, egg-shaped at base, acutely pointed at tip. Frudt Hairy pod 1 in long. Also 1-seeded, pale, rounded, underground peanut. Preferred Habitat—Moist thickets, shady roadsides. Flowering Season—August—September. Distribution—New Brunswick westward to Nebraska, south to Gulf of Mexico. Amphicarpea (‘‘seed at both ends”), the Greek name by which this graceful vine was formerly known, emphasizes its most 27 From Blue to Purple interesting feature, that, nevertheless, seems to mary a foolish dus plication of energy on Nature’s part. Why should the same plant bear two kinds of blossoms and seeds? Among the foliage of low shrubbery and plants in shady lanes and woodside thickets, we see the delicate, drooping clusters of lilac blossoms hanging where bees can readily discover them and, in pilfering their sweets, trans- fer their pollen from flower to flower. Butin case of failure to intercross these blossoms that are dependent upon insect help to set fertile seed, what then? Must the plant run the risk of ex- tinction? Self-fertilization may be an evil, but failure to produce seed at all is surely the greatest one. To guard against sucha calamity, insignificant looking flowers that have no petals to open for the enticing of insects, but which fertilize themselves with their own pollen, produce abundant seed close to the ground or under it. Then what need of the showy blossoms hanging in the thicket above? Close inbreeding in the vegetable world, as in the animal, ultimately produces degenerate offspring; and although the showy lilac blossoms of the wild peanut yield comparatively few cross fertilized seeds, these are quite sufficient to enable the vine to maintain those desired features which are the inheritance from an cestors that struggled in their day and generation after perfection. No plant dares depend upon its cleistogamous or blind flowers alone for offspring; and in the sixty or more genera containing these curious growths, that usually look like buds arrested in de- velopment, every plant that bears them bears also showy flowers dependent upon cross-pollination by insect aid. The boy who “* Drives home the cows from the pasture Up through the long shady lane ” knows how reluctantly they leave the feast afforded by the wild peanut. Hogs, rooting about in the moist soil where it grows, unearth the hairy pods that should produce next year’s vines; hence the Pp or excuse for branding a charming plant witha repellent folk-name. Violets (Viola) Violet family Lacking perfume only to be a perfectly satisfying flower, the Common, Purple, Meadow, or Hooded Blue Violet (V. obli- qua)—the V. cucullata of Gray—has nevertheless established it- self in the hearts of the people from the Arctic to the Gulf as no sweet-scented, showy, hothouse exotic has ever done. Royal in color as in lavish profusion, it blossoms every where—in woods, waysides, meadows, and marshes, but always in finer form in cool, shady dells; with longer flowering scapes in meadow bogs; 28 From Blue to Purple and with longer leaves than wide in swampy woodlands. The heart-shaped, saw-edged leaves, folded toward the centre when newly put forth, and the five-petalled, bluish-purple, golden- hearted blossom are too familiar for more detailed description. From the three-cornered stars of the elastic capsules, the seeds are Scattered abroad. Beards on the spurred lower petal and the two side petals give the bees a foothold when they turn head downward, as some must, to suck nectar. This attitude enables them to receive the pollen dusted on their abdomens, when they jar the flower, at a point nearest their pollen-collecting hairs. It is also an economical advantage to the flower which can sift the pollen downward on the bee instead of exposing it to the pollen-eating interlopers. Among the latter may be classed the humblebees and butterflies whose long lips and tongues pilfer ad libitum. ‘‘ For the proper visitors of the bearded violets,” says Professor Robertson, ‘‘ we must look to the small bees, among which the Osmias are the most important.” When science was younger and hair splitting an uncom- mon indulgence of botanists, the Early Blue Violet (Viola pal- mata) was thought to be simply a variety of the common purple violet, whose heart-shaped leaves frequently show a tendency to divide into lobes. But the early blue violet, however roundish or heart-shaped its early leaves may be, has the later ones variously divided into from three to thirteen lobes, often almost as much cut on the sides as the leaves of the bird’s-foot violet. In dry soil, chiefly in the woods, this violet may be found from Southern Canada westward to Minnesota, and south to northern boundaries of the Gulf States. Only its side petals are bearded to form foot- rests for the insects that search for the deeply secreted nectar. Many butterflies visit this flower. On entering it a bee must first touch the stigma before any fresh golden pollen is released from the anther cone, and cross-fertilization naturally results. In shale and sandy soil, even in the gravel of hillsides, one finds the narrowly divided, finely cut leaves and the bicolored beardless blossom of the Bird’s-foot Violet (V. pedata), pale bluish purple on the lower petals, dark purple on one or two upper ones, and with a heart of gold. The large, velvety, pansy-like blossom and the unusual foliage which rises in rather dense tufts are suffi- cient to distinguish the plant from its numerous kin. This spe- cies produces no cleistogamous or blind flowers. Frequently the bird’s-foot violet blooms a second time, in autumn, a delightful eccentricity of this family. The spur of its lower petal is long and very slender, and, as might be expected, the longest-tongued bees and butterflies are its most frequent visitors. These receive the pollen on the base of the proboscis. 29 From Blue to Purple The Woolly Blue Violet (V. sororia), whose stems and younger leaves, at least, are covered with hairs, and whose pur- plish-blue flowers are more or less bearded within, prefers a shady but dry situation; whereas its next of kin, the Arrow-leaved Violet (VY. sagittata), delights in moist but open meadows and marshes. The latter’s long, arrow, or halbert-shaped leaves, usually entire above the middle, but slightly lobed below it, may rear themselves nine inches high in favorable soil, or in dry uplands perhaps only twoinches. The flowering scapes grow as tall as the leaves. All but the lower petal of the large, deep, dark, purplish-blue flower are bearded. This species produces an abundance of late cleis- togamous flowers on erect stems. These peculiar greenish flowers without petals, that are so often mistaken for buds or seed vessels; that never open, but without insect aid ripen quantities of fertile seed, are usually borne, if not actually under ground, then not far above it, on nearly all violet plants. It will be observed that all species which bear blind flowers rely somewhat on showy, cross-fertilized blossoms also to counteract degeneracy from close inbreeding. The Ovate-leaved Violet (V. ovata), formerly reckoned as a mere variety of the former species, is now accorded a distinct rank. Not all the blossoms, but an occasional clump, has a faint perfume like sweet clover. The leaf is elongated, but rather too round to be halbert-shaped ; the stems are hairy ; and the flowers, which closely resemble those of the arrow-leaved violet, are earlier; making these two species, which are popularly mistaken for one, among the earliest and commonest of their clan. The dry soil of pane woods and thickets is the ovate-leaved violet’s preferred abitat. In course of time the lovely English, March, or Sweet Violet, (V. odorata), which has escaped from gardens, and which is now rapidly increasing with the help of seed and runners on the Atlantic and the Pacific coasts, may be established among our wild flowers. No blossom figures so prominently in European literature. In France, it has even entered the political field since Napoleon’s day. Yale University has adopted the violet for its own especial flower, although it is the corn-flower, or bachelor’s button (Centaurea cyanus) that is the true Yale blue. Sprengel, who made a most elaborate study of the violet, condensed the result of his research into the following questions and answers, which are given here because much that he says applies to our own native species, which have been too little studied in the modern scientific spirit : “1. Why is the flower situated on a long stalk which is up- right, but curved downwards at the free end? In order that it may hang down; which, firstly, prevents rain from obtaining 30 From Blue to Purple access to the nectar; and, secondly, places the stamens in such a position that the pollen falls into the open space between the pistil and the free ends of the stamens. If the flower were up- right, the pollen would fall into the space between the base of the stamen and the base of the pistil, and would not come in contact with the bee. ‘*2. Why does the pollen differ from that of most other insect-fertilized flowers? In most of such flowers the insects themselves remove the pollen from the anthers, and it is therefore important that the pollen should not easily be detached and carried away by the wind. In the present case, on the contrary, it is desirable that it should be looser and dryer, so that it may easily fall into the space between the stamens and the pistil. If it re- mained attached to the anther, it would not be touched by the bee, and the flower would remain unfertilized. **3, Why is the base of the style so thin? In order that the bee may be more easily able to bend the style. ‘4. Why is the base of the style bent? For the same reason. The result of the curvature is that the pistil is much more easily bent than would be the case if the style were straight. ‘«s. Finally, why does the membranous termination of the upper filament overlap the corresponding portions of the two middle stamens? Because this enables the bee to move the pistil, and thereby to set free the pollen more easily than would be the case under the reverse arrangement.” In high altitudes of New England, Colorado, and northward, where the soil is wet and cold, the pale lilac, slightly bearded petals, streaked with darker veins, of the Marsh Violet (V. palustris), with its almost round leaves, may be found from May to June. All through the White Mountains one finds it abundant. A peculiarity of the Dog or Running Violet (V. Labradorica) is that its small, heart-shaped leaves are set along the branching stem, and its pale purple blossoms rise from their angles, pansy fashion. From March to May it blooms throughout its wide range in wet, shady places. Its English prototype, called by the same invidious name, was given the prefix ‘‘dog,” because the word, which is always intended to express contempt in the British mind, is applied in this case for the flower’s lack of fragrance. Whena bee visits this violet, his head coming in contact with the stigma jars it, thus opening the little pollen box, whose contents must fall out on his head and be carried away and rubbed off where it will fertilize the next violet visited. 31 From Blue to Purple Sea Lavender; Marsh Rosemary; Canker- root; Ink-root (Limonium Carolinianum) Plumbago family (Statice Limonium of Gray) Flowers—Very tiny, pale, dull lavender, erect, set along upper side of branches. Calyx 5-toothed, tubular, plaited; corolla of 5 petals opposite as many stamens; 1 pistil with 5 thread-like styles. Scape: 1 to 2 ft. high, slender, leafless, much branched above. Leaves: All from thick, fleshy rootstock, narrowly oblong, tapering into margined petioles, thick, the edges slightly waved, not toothed; midrib prominent. Preferred Habitat—Salt meadows and marshes. Flowering Season—)uly—October. Distribution — Atlantic coast from Labrador to Florida, westward along the Gulf to Texas; also in Europe. Seen in masses, from a little distance, this tiny flower looks like blue-gray mist blown in over the meadows from sea, and on closer view each plant suggests sea-spray itself. Thrifty house- wives along the coast dry it for winter bouquets, partly for orna- ment and partly because there is an old wives’ tradition that it keeps away moths. Statice, from the Greek verb to stop, hence an astringent, was the generic name formerly 9 to the plants, with whose roots these same old women believed they cured canker sores. Fringed Gentian (Gentiana crinita) Gentian family Flowers—Deep, bright blue, rarely white, several or many, about 2 in. high, stiffly erect, and solitary at ends of very long foot- Stalk. Calyx of 4 unequal, acutely pointed lobes. Corolla funnel form, its four lobes spreading, rounded, fringed around ends, but scarcely on sides. Four stamens inserted en corolla tube ; 1 pistil with 2 stigmas. Stem: 1 to 3 ft. high, usually branched, leafy. Leaves : Opposite, upper ones acute at tip, broadening to heart-shaped base, seated on stem. Fruit: A spindle-shaped, 2-valved capsule, contain- ing numerous scaly, hairy seeds. ; i 7 Preferred Habitat—Low, moist meadows and woods. Flowering Season—September—November. Distribution—Quebec, southward to Georgia, and westward be- yond the Mississippi. ' 32 From Blue to Purple ** Thou waitest late, and com’st alone When woods are bare and birds have flown, And frosts and shortening days portend The aged year is near his end. ** Then doth thy sweet and quiet eye Look through its fringes to the sky, Blue—blue—as if that sky let fall A flower from its cerulean wall.” When we come upon a bed of gentians on some sparkling October day, we can but repeat Bryant’s thoughts and express them prosaically who attempt description. In dark weather this sunshine lover remains shut, to protect its nectar and pollen from possible showers. An elusive plant is this gentian, which by no means always reappears in the same places year after year, for it is an annual whose seeds alone perpetuate it. Seating them- selves on the winds when autumn gales shake them from out the home wall, these little hairy scales ride afar, and those that are so fortunate as to strike into soft, moist soil at the end of the journey, germinate. Because this flower is so rarely beautiful that few can resist the temptation of picking it, it is becoming sadly rare near large settlements. The special importance of producing a quantity of fertile seed has led the gentians to adopt proterandry—one of the commonest, because most successful, methods of insuring it. The anthers, coming to maturity early, shed their pollen on the bumblebees that have been first attracted by their favorite color and the entic- ing fringes before they crawl half way down the tube where they can reach the nectar secreted in the walls. After the pollen has been carried from the early flowers, and the stamens begin to wither, up rises the pistil to be fertilized with pollen brought from . anewly opened blossom by the bee or butterfly. The late de- velopment of the pistil accounts for the error often stated, that some gentians have none. No doubt the fringe, which most scientists regard simply as an additional attraction for winged insects, serves a double purpose in entangling the feet of ants and other crawlers that would climb over the edge to pilfer sweets clearly intended for the bumblebee alone. Fifteen species of gentian have been gathered during a half- hour walk in Switzerland, where the pastures are spread with sheets of blue. Indeed, one can little realize the beauty of these heavenly flowers who has not seen them among the Alps. The Five-flowered or Stiff Gentian, or Ague-weed (Gentiana guinquefolia)—G. quinquefiora of Gray—has its five-parted, small, picotee-edged blue flowers arranged in clusters, not exceed- ing seven, at the ends of the branches or seated in the leaf-axils. The slender, branching, ridged stem may rise only two inches in dry soil; or perhaps two feet in rich, moist, rocky ground, where 3 33 j From Blue to Purple it grows to perfection, especially in mountainous regions. From Canada to Florida and westward to Missouri is its range, and be- ginning to bloom in August southward, it may not be found until September in the Catskills, and in October it is still in its glory in Ontario. The colorless, bitter juice of many of the gentian tribe has long been valued as a tonic in medicine. Evidently the but- terflies that pilfer this ‘‘ague-weed,” and the bees that are its legitimate feasters, find something more delectable in its blue walls. A deep, intense blue is the Closed, Blind, or Bottle Gentian (G. Andrewsii), more truly the color of the ‘‘male bluebird’s back,” to which Thoreau likened the paler fringed gentian. Rarely some degenerate plant bears white flowers. As it is a perennial, we are likely to find it in its old haunts year after year ; nevertheless its winged seeds sail far abroad to seek pastures new. This gentian also shows a preference for moist soil. Gray thought that it expanded slightly, and for a short time only in sunshine, but added that, although it is proterandrous, 7.¢. it matures and sheds its pollen before its stigma is susceptible to any, he believed it finally fertilized itself by the lobes of the stigma curling backward until they touched the anthers. But Gray was doubtless mistaken. Several authorities have recently proved that the flower is adapted to bumblebees. It offers them the last feast of the season. for although it comes into bloom in August southward, farther northward it lasts through October. % x : Now, how can a bumblebee enter this inhospitable-looking! flower? If he did but know it, it keeps closed for his special benefit, having no fringes or hairs to entangle the feet of crawling pilferers, and no better way of protecting its nectar from rain and marauding butterflies that are not adapted to itsneeds. But he is a powerful fellow. Watch him alight on a cluster of blossoms,’ select the younger, nectar-bearing ones, that are distinctly marked white against a light-blue background at the mouth of the corolla for his special guidanee. Old flowers from which the nectar has been removed turn deep reddish purple, and the white path- finders become indistinct. With some difficulty, it is true, the bumblebee (B. Americanorum) thrusts his tongue through the valve of the chosen flower where the five plaited lobes overlap one another; then he pushes with all his might until his head hav- ing passed the entrance most of his body follows, leaving only his hind legs and the tip of his abdomen sticking out as he makes the circuit. He has much sense as well as muscle, and does not risk imprisonment in what must prove a tomb by a total and unneces- sary disappearance within the bottle. Presently he backs out, brushes the pollen from his head and thorax into his baskets, and is off to fertilize an older, stigmatic flower with the few grains of quickening dust that must remain on his velvety head. 4 COMMON PURPLE VIOLET CLOSED OR BLIND GENTIAN From Blue to Purple Wild Blue Phlox (Phlox divaricata) Phlox family Flowers—Pale lilac blue, slightly fragrant, borne on sticky pcdicels, in loose, spreading clusters. Calyx with 5 long, sharp teeth. Corolla of 5 flat lobes, indented like the top of a heart, and united into a slender tube ; 5 unequal, straight, short stamens in corolla tube; 1 pistil with 3 stigmas. Stem. 1 to 2 ft. high, finely coated with sticky hairs above, erect or spread- ing, and producing leafy shoots from base. Leaves: Of flower- ing stem—opposite, oblong, tapering to a point; of sterile shoots—oblong or egg-shaped, not pointed, 1 to 2 in. long. Preferred Habitat—Moist, rocky woods. Flowering Season—April—June. Distribution—Eastern Canada to Florida, Minnesota to Arkansas. The merest novice can have no difficulty in naming the flower whose wild and cultivated relations abound throughout North America, the almost exclusive home of the genus, although it is to European horticulturists, as usual the first to see the pos- sibilities in our native flowers, that we owe the gay hybrids in our gardens. Mr. Drummond, a collector from the Botanical Society of Glasgow, early in the thirties sent home the seeds of a species from Texas, which became the ancestor of the gorgeous annuals, the Drummond phloxes ofcommerce to-day ; and although he died of fever in Cuba before the plants became generally known, not even his kinsman, the author of ‘‘ Natural Law in the Spiritual World,” has done more to immortalize the family name. While the wild blue phlox is sometimes cultivated, it is the Garden Phlox (P. paniculata), common in woods and thickets from Pennsylvania to Illinois and southward, that undera gardener’s care bears the large terminal clusters of purple, magenta, crimson, pink, and white flowers abundant in old-fashioned, hardy borders. From these it has escaped so freely in many sections of the North and East as to be counted among the local wild flowers. Unless the young offshoots are separated from the parent and given a nook of their own, the flower quickly reverts to the original type. Euro- ag cultivators claim that the most brilliant colors are obtained yy crossing annual with perennial phloxes. Wild Sweet William (P. maculata), another perennial much sought by cultivators, loves the moisture of low woods and the neighborhood of streams in the Middle and Western States when it is free to choose its habitat ; but it, too, has so freely escaped from gardens farther north into dry and dusty roadsides, that any 35 From Blue to Purple one who has passed the ruins of Hawthorne’s little red cottage at Lenox, for example, and seen the way his wife’s clump of white phlox under his study window has spread to cover an acre of hillside, would suppose it to be luxuriating in its favorite locality. This variety of the species (var. Candida) lacks the purplish flec on stem and lower leaves responsible for the specific name of the type. Pinkish purple or pink blossoms are borne in a rather narrow, elongated panicle on the typical Sweet William. Most members of the phlox family resort to the trick of coat- ing the upper stem and the peduncles immediately below the flowers with a sticky secretion in which crawling insects, intent on pilfering sweets, meet their death, just as birds are caught on limed twigs. Butterflies, for whom phloxes have narrowed their tubes to the exclusion of most other insects, are their benefactors; but long-tongued bees and flies often seek their nectar. Indeed, the number of strictly butterfly-flowers is surprisingly small. Virginia Cowslip; Tree or Smooth Lungwort; Blue-bells (Mertensta Virginica) Borage family Fliowers—Pinkish in bud, afterward purplish blue, fading to light blue ; about 1 in. long, tubular, funnel form, the tube of corolla not crested; spreading or hanging on slender pedicels in showy, loose clusters at end of smooth stem from | to 2 ft. high; stamens 5, inserted on corolla; 1 pistil; ovary of 4 divisions. Leaves: Large, entire, alternate, veiny, oblong or obovate, the upper ones seated on stem ; lower very large ones diminishing toward base into long petioles; at first rich, dark purple, afterward pale bluish gray. Fruit: 4 seed-like little nuts, leathery, wrinkled when mature. Preferred Habitat—Alluvial ground, low meadows, and along streams. Flowering Season—March—May. Disiribution—Southern Canada to South Carolina and Kansas, west to Nebraska; most abundant in middle West. Not to be outdone by its cousins the heliotrope and the forget-me-not, this lovely and far more showy spring flower has found its way into the rockwork and sheltered, moist nooks of many gardens, especially in England, where Mr. W. Robinson, who has appealed for its wider cultivation in that perennially charming book, ‘‘The English Flower Garden,” says of the Mertensias : ‘‘ There is something about them more beautiful in form of foliage and stem, and in the graceful way in which they tise to panicles of blue, than in almost any other family. . . 4 36 From Blue to Purple Handsomest of all is the Virginia cowslip.” And yet Robinson never saw the alluvial meadows in the Ohio Valley blued with lovely masses of the plant in April. A great variety of insects visit this blossom, which, being tubular, conducts them straight to the ample feast ; but not until they have deposited some pollen brought from another flower on the stigma in their way. The anthers are too widely separated from the stigma to make self-fertilization likely. Occasionally one finds the cowslips perforated by clever bumblebees. As only the females, which are able to sip far deeper cups, are flying when they bloom, they must be either too mischievous or too lazy to drain them in the legitimate manner. Butterflies have only to stand ona flower, not to enter it, in order to sip nectar from the four glands that secrete it abundantly. Forget-me-not; Mouse-ear; Scorpion Grass; Snake Grass; Love Me (Myosotis palustris) Borage family Flewers—Pure blue, pinkish, or white, with yellow eye; flat, 5- lobed, borne in many-flowered, long, often 1-sided racemes. Calyx 5-cleft ; the lobes narrow, spreading, erect, and open in fruit; 5 stamens inserted on corolla tube ; style thread- like ; ovary 4-celled. Stem: Low, branching, leafy, slender, hairy, partially reclining. Leaves: (Myosotis = mouse-ear) oblong, alternate, seated on stem, hairy. Fruit: Nutlets, angled and keeled on inner side. Preferred Habitat—Escaped from gardens to brooksides, marshes, and low meadows. flowering Season—May—July. Distribution—Native of Europe and Asia, now rapidly spreading from Nova Scotia southward to New Jersey, Pennsylvania, and beyond. How rare a color blue must have been originally among our flora is evident from the majority of blue and purple flowers that, although now abundant here and so perfectly at home, are really quite recent immigrants from Europe and Asia, But our dryer, hotter climate never brings to the perfection attained in England “The sweet forget-me-nots That grow for happy lovers.” Tennyson thus ignores the melancholy association of the flower in the popular legend which tells how a lover, when trying 4 From Blue to Purple to gather some of these blossoms for his sweetheart, fell into a deep pool, and threw a bunch on the bank, calling out, as he sank for- ever from her sight, ‘‘Forget me not.” Another dismal myth sends its hero forth seeking hidden treasure caves in a mountain, under the guidance of a fairy. He fills his pockets with gold, but not heeding the fairy’s warning to ‘‘ forget not the best”’—z.2., the myosotis—he is crushed by the closing together of the moun- tain. Happiest of all is the folk-tale of the Persians, as told by their poet Shiraz: ‘‘It was in the golden morning of the early world, when an angel sat weeping outside the closed gates of Paradise. He had fallen from his high estate through loving a daughter of earth, nor was he permitted to enter again until she whom he loved had planted the flowers of the forget-me-not in every corner of the world. He returned to earth and assisted her, and together they went hand in hand. When their task was ended, they entered Paradise together, for the fair woman, without tasting the bitterness of death, became immortal like the angel whose love her beauty had won when she sat by the river twining forget-me- nots in her hair.” It was the golden ring around the forget-me-not’s centre that first led Sprengel to believe the conspicuous markings at the en- trance of many flowers served as pathfinders to insects. This golden circle also shelters the nectar from rain, and indicates to the fly or bee just where it must probe between stigma and anthers to touch them with opposite sides of its tongue. Since it may probe from any point of the circle, it is quite likely that the side of the tongue that touched a pollen-laden anther in one flower will touch the stigma in the next one visited, and so cross- fertilize it. But forget-me-nots are not wholly dependent on in- sects. When these fail, a fully mature flower is still able to set fertile seed by shedding its own pollen directly on the stigma. The Smaller Forget-me-not (M. Jaxa), formerly accounted a mere variety of palustris, but now defined as a distinct species, is a native, and therefore may serve to show how its European relative here will deteriorate in the dryer atmosphere of the New World. Its tiny turquoise flowers, borne on long stems from a very loose raceme, gleam above wet, muddy places from New- foundland and Eastern Canada to Virginia and Tennessee. Even smaller still are the blue or white flowers of the Field Forget-me-not, Scorpion Grass, or Mouse-ear (M. arvenis), whose stems and leaves are covered with bristly hairs. It blooms from August to July in dry places, even on hillsides, an unusual locality in which to find a member of this moisture-loving clan. All the flowers remain long in bloom, continually forming new es on a lengthening stem, and leaving behind little empty green calices. 38 From Blue to Purpie Viper’s Bugloss; Blue-weed; Viper’s Herb or Grass; Snake-flower; Blue-thistle (Echtum vulgare) Borage family Flowers—Bright blue, afterward reddish purple, pink in the bud, numerous, clustered on short, !-sided, curved spikes rolled up at first, and straightening out as flowers expand. Calyx deeply 5-cleft; corolla 1 in. long or less, funnel form, the 5 lobes unequal, acute; 5 stamens inserted on corolla tube, the filaments spreading below, and united above into slen- der appendage, the anthers forming a cone. 1 pistil with 2 stigmas. Stem: 1 to 2% ft. high; bristly-hairy, erect, spotted. Leaves: Hairy, rough, oblong to lance-shaped, alternate, seated on stem, except at base of plant. Preferred Habitat—Dry fields, waste places, roadsides. Flowering Season—June—July. Distribution—New Brunswick to Virginia, westward to Nebraska; Europe and Asia. In England, from whose gardens this plant escaped long ago, a war of extermination that has been waged against the vigorous, beautiful weed by the farmers has at last driven it to the extrem- ity of the island, where a few stragglers about Penzance testify to the vanquishing of what must once have been a mighty army. From England a few refugees reached here in 1683, no one knows how; but they proved to be the vanguard of an aggressive and victorious host that quickly overran our open, hospitable country, as if to give vent to revenge for long years of persecution at the hands of Europeans. ‘‘It is a fact that all our more pernicious weeds, like our vermin, are of Old-World origin,” says John Bur- roughs. ‘*. . . Perhaps the most notable thing about them, when compared with our native species, is their persistence, not to say pugnacity. They fight for the soil; they plant colonies here and there, and willnot berooted out. Our native weedsare for the most part shy and harmless, and retreat before civilization. We have hardly a weed we can call our own.” Years ago, when simple folk believed God had marked plants with some sign to indicate the special use for which each was intended, they regarded the spotted stem of the bugloss, and its seeds shaped like a serpent’s head, as certain indications that the herb would cure snake bites. Indeed, the genus takes its name from Echis, the Greek for viper. Because it is showy and offers accessible nectar, a great va- riety of insects visit the blue-weed; Miller alone observed sixty- seven species about it. We need no longer wonder at its fertil- ity. Of the five stamens one remains in the tube, while the 39 From Blue to Purple other four project and form a convenient alighting place for visitors, which necessarily dust their under sides with pollen as they enter; for the red anthers were already ripe when the flower opened. Then, however, the short, immature pistil was kept below. After the stamens have shed their pollen and there can be no longer danger of self-fertilization, it gradually elongates itself beyond the point occupied by them, and divides into two little horns whose stigmatic surfaces an incoming pollen-laden insect cannot well fail to strike against. Cross-pollination is so thoroughly secured in this case that the plant has completely lost the power of fertilizing itself. Umnwelcome visitors like ants, which would pilfer nectar without rendering any useful service in return, are warded off by the bristly, hairy foliage. Several kinds of female bees seek the bugloss exclusively for food for their larvze as well as for themselves, sweeping up the abundant pollen with their abdominal brushes as they feast without effort. Blue Vervain; Wild Hyssop: Simpler’s Joy (Verbena hastata) Vervain family Flowers—Very small, purplish blue, in numerous slender, erect, compact spikes. Calyx 5-toothed ; corolla tubular, unequally 5-lobed ; 2 pairs of stamens ; 1 pistil. Stem; 3 to 7 ft. high, rough, branched above, leafy, 4-sided. Leaves: Opposite, stemmed, lance-shaped, saw-edged, rough ; lower ones lobed at base. Preferred Habitat—Moist meadows, roadsides, waste places. Flowering Season—June—September. Distribution—United States and Canada in almost every part. Seeds below, a circle of insignificant purple-blue flowers in the centre, and buds at the top of the vervain’s slender spires do not produce a striking effect, yet this common plant certainly does not lack beauty. John Airrounks, ever ready to say a kindly, appreciative word for any weed, speaks of its drooping, knotted threads, that ‘‘make a pretty etching upon the winter snow.” Bees, the vervain’s benefactors, are usually seen cling- ing to the blooming spikes, and apparently sleep on them. Bor- rowing the name of simpler’s joy from its European sister, the flower has also appropriated much of the tradition and folk-lore centred about that plant which herb-gatherers, or simplers, truly delighted to see, since none was once more salable. European Vervain (V. officinalis) Herb-of-the-Cross, Berbine, Holy-herb, Enchanter’s Plant, Juno’s Tears, Pigeon-grass, Light ning Plant, Simpler’s Joy, and so on through a long list of popu- 40 From Blue to Purple lar names for the most part testifying to the plant’s virtue as a love-philter, bridal token, and general cure-all, has now become naturalized from the Old World on the Atlantic and Pacific Slopes, and is rapidly appropriating waste and cultivated ground until, in many places, it is truly troublesome. In general habit like the blue vervain, its flowers are more purplish than blue, and are scattered, not crowded, along the spikes. The leaves are deeply, but less acutely, cut. Ages before Christians ascribed healing virtues to the ver- vain—found growing on Mount Calvary, and therefore possessing every sort uf miraculous power, according to the logic of simple peasant folk—the Druids had counted it among their sacred plants. ‘‘When the dog-star arose from unsunned spots” the priests gathered it. Did not Shakespeare’s witches learn some of their uncanny rites from these reverend men of old? One is impressed with the striking similarity of many customs recorded of both. Two of the most frequently used ingredients in witches’ cauldrons were the vervain and the rue. ‘‘ The former probably derived its notoriety from the fact of its being sacred to Thor, an honor which marked it out, like other lightning plants, as pecu- liarly adapted for occult uses,” says Mr. Thiselton Dyer in his ‘* Folk-lore of Plants.” ‘‘ Although vervain, therefore, as the en- chanter’s plant, was gathered by witches to do mischief in their incantations, yet, as Aubrey says, it ‘hinders witches from their will,’ a circumstance to which Drayton further refers when he speaks of the vervain as ‘’gainst witchcraft much avayling.’” ow we understand why the children of Shakespeare’s time hung vervain and dill with a horseshoe over the door. In his eighth Eclogue, Virgil refers to vervain as a charm to recover lost love. Doubtless this was the verbena, the herba Sacra employed in ancient Roman sacrifices, according to Pliny. In his day the bridal wreath was of verbena, gathered by the bride herself. Narrow-ieaved Vervain (V. angustifolia), like the blue vervain, has a densely crowded spike of tiny purple or blue flowers that quickly give place to seeds, but usually there is only one spike at the end of a branch. The leaves are narrow, lance-shaped, acute, saw-edged, rough. From Massachusetts and Florida westward to Minnesota and Arkansas one finds the plant blooming in dry fields from June to August, after the parsimonious manner of the vervain tribe. It is curious that the vervain, or verbena, employed by brides for centuries as the emblem of chastity, should be one of the notorious botanical examples of a wilful hybrid. Generally, the individuals of distinct species do not interbreed ; but verbenas are often difficult to name correctly in every case because of theif susceptibility to each other’s pollen—the reason why the garden ai From Blue to Purple verbena may so easily be made to blossom forth into whatever hue the gardener wills. His plants have been obtained, for the most part, from the large-flowered verbena, the beautiful purple, blue, or white species of our Western States (VY. Canadensis)| crossed with brilliant-hued species imported from South America. Mad-dog Skullcap or Helmet-flower; Mad- weed; Hoodwort (Scutellaria lateriflora) Mint family Flowers—Blue, varying to whitish ; several or many, % in. long, growing in axils of upper leaves or in 1-sided spike-like racemes. Calyx 2-lipped, the upper lip with a helmet-like rotuberance; corolla 2-lipped; the lower, 3-lobed lip spread- ing; the middle lobe larger than the side ones. Stamens, 4, in pairs, under the upper lip; upper pair the shorter ; one pis- til, the style unequally cleft in two. Stem: Square, smooth, leafy, branched, 8 in. to 2 ft. high. Leaves: Opposite, oblong to lance-shaped, thin, toothed, on slender pedicles, 1 to 3 in. long, growing gradually smaller toward top of stem. Fruit; 4 nutlets. Preferred Habitat—Wet, shady ground. Flowering Season—July—September. Distribution—Uneven throughout United States and the British Possessions. By the helmet-like appendage on the upper lip of the calyx, which to the imaginative mind of Linneus suggested Scutellum (a little dish), which children delight to spring open for a view of the four tiny seeds attached at the base when in fruit, one knows this to be a member of the skullcap tribe, a widely scattered genus of blue and violet two-lipped flowers, some small to the point of insignificance, like the present species, others showy enough for the garden, but all rich in nectar, and eagerly sought by bees. The wide middle lobe of the lower lip forms a convenient plat- form on which to alight; the stamens in the roof of a newly opened blossom dust the back of the visitor as he explores the nectary ; and as the stamens of an older flower wither when they have shed their pollen, and the style then rises to occupy their position, it follows that, in flying from the top of one spike of flowers to the bottom of another, where the older ones are, the visitor, for whom the whole scheme of color, form, and arrange- ment was planned, deposits on the sticky top of the style some of the pollen he has brought with him, and so cross-fertilizes the flower. When the seeds begin to form and the now useless corolla drops off, the helmet-like appendage on the top of the calyx 42 From Blue to Purple enlarges and meets the lower lip, so enclosing and protecting the tiny nutlets. After their maturity, either the mouth gapes from dryness, or the appendage drops off altogether, from the same cause, to release the seeds. Old herb doctors, who professed to cure hydrophobia with this species, are responsible for its English misnomer. Perhaps the most beautiful member of the genus is the Showy Skullcap (S. serrata), whose blue corolla, an inch long, has its narrow upper lip shorter than the spreading lower one. The flowers are set opposite each other at the end of the smooth stem, which rises from one to two feet high in the woods throughout a southerly and westerly range. As several other skullcaps have distinctly saw-edged leaves, this plant might have been given a more distinctive adjective, thinks one who did not have the naming of 200,000 species ! Above dry, sandy soil from New York and Michigan south- ward the Hairy Skullcap (S. pilosa) lifts short racemes of blue flowers that are only half an inch long, and whose lower lip and lobes at either side are shorter than the arched upper lip. Most parts of the plant are covered with down, the lower stem being especially hairy ; and this fact determines the species when con-~ nected with its rather distant pairs of indented, veiny leaves, rang-~ ing from oblong to egg-shaped, and furnished with petioles which grow gradually shorter toward the top, where pairs of bracts, seated on the stem, part to let the flowers spring from their axils. The Larger or Hyssop Skullcap (S. integrifolia) rarely has a dent in its rounded oblong leaves, which, like the stem, are covered with fine down. Its lovely, bright blue flowers, an inch long, the lips of about. equal length, are grouped opposite each other at the top of a stem that never lifts them higher than two feet ; and so their beauty is often concealed in the tall grass of roadsides and meadows and the undergrowth of woods and thickets, where they bloom from May to August, from southern New England to Gulf of Mexico, westward to Texas. This tribe of plants is almost exclusively North American, but the hardy Marsh Skullcap, or Hooded Willow-herb (S. galericulata), at least, roams over Europe, and Asia also, with the help of runners, as well as seeds that, sinking into the soft earth of swamps and the borders of brooks, find growth easy. The blue flowers which grow singly in the axils of the upper leaves are quite as long as those of the larger and the showy skullcaps ; the oblong, lance- shaped leaves, which are mostly seated on the branching stem, opposite each other, have low teeth. Why do leaves vary as they 43 From Blue to Purple do, especially in closely allied species P ‘‘ The causes which have led to the different forms of leaves have been, so far as I know,” says Sir John Lubbock, ‘‘ explained in very few cases: those of the shapes and structure of seeds are tolerably obvious in some species, but in the majority they are still entirely unexplained ; and, even as regards the blossoms themselves, in spite of the numerous and conscientious labors of so many eminent naturalists, there is as yet no single species thoroughly known to us.” Ground Ivy or Joy; Gill-over-the-Ground; Field Balm; Creeping Charlie (Glecoma hederacea) Mint family (Nepeta Glechoma of Gray) Flowers—Light bluish purple, dotted with small specks of reddish violet ; growing singly or in clusters along stem, seated in leaf axils ; calyx hairy, with 5 sharp teeth ; corolla tubular, over % in. long, 2-lipped, the upper lip 2-lobed, lower lip with 3 spreading lobes, middle one largest; 4 stamens in pairs under upper lip; the anther sacs spreading ; 1 pistil with 2-lobed style. Stem: Trailing, rooting at intervals, sometimes 18 in. long, leafy, the branches ascending. Leaves: From % to1¥% in. across ; smooth, rounded, kidney-shaped, scallop-edged. Preferred Habitat—Waste places, shady ground. Flowering Season—March—May. Distribution—Eastern half of Canada and the United States, from Georgia and Kansas northward. Besides the larger flowers, containing both stamens and pistils, borne on this little immigrant, smaller female flowers, containing a pistil only, occur just as they do in thyme, mint, marjoram, and doubtless other members of the great family to which all belong. Miller attempted to prove that these small flowers, being the least showy, are the last to be visited by insects, which, having pre- viously dusted themselves with pollen from the stamens of the larger flowers when they first open, are in a condition to make cross-fertilization certain. So much for the small flower’s method of making insects serve its end ; the larger flowers have another way. At first they are male ; that is, the pistil is as yet undevel- oped and the four stamens are mature, ready to shed pollen on any insect alighting on the lip. Later, when the stamens are past maturity, the pistil elongates itself and is ready for the ecep- tion of pollen brought from younger flowers. Many bl. 3soms are male on the first day of opening, and female later, to protect themselves against self-fertilization. 44 From Blue to Purplé In Europe, where the aromatic leaves of this little creeper were Jong ago used for fermenting and clarifying beer, it is known by such names as ale-hoof and gill ale—gill, it is said, being derived from the old French word, guiller, to ferment or make merry. Having trailed across Europe, the persistent hardy plant is now creeping its way over our continent, much to the disgust of cattle, which show unmistakable dislike for a single leaf caught up in a mouthful of herbage. Very closely allied to the ground ivy is the Catmint or Catnip (Nepeta Cataria\, whose pale-purple, or nearly white flowers, dark- spotted, may be most easily named by crushing the coarsely toothed leaves in one’s hand. It is curious how cats will seek out this hoary-hairy plant in the waste places where it grows and become half-crazed with delight over its aromatic odor. Self-heal: Heal-all: Blue Curls: Heart-of-the- Earth; Brunella (Prunella vulgaris) Mint family Flowers—Purple and violet, in dense spikes, somewhat resem- bling a clover head; from 34 to 1in. long in flower, becoming 4 times the length in fruit. Corolla tubular, irregularly 2-lipped, the upper lip darker and hood-like ; the lower one 3-lobed, spreading, the middle and largest lobe fringed ; 4 twin-like stamens ascending under upper lip; filaments of the lower and longer pair 2-toothed at summit, one of the teeth bearing an anther, the other tooth sterile ; style thread-like, shorter than stamens, and terminating in a 2-cleft stigma. Calyx 2-parted, half the length of corolla, its teeth often hairyon edges. Stem: 2 in. to 2 ft. high, erect or reclining, simple or branched. Leaves: Opposite, oblong. Fruit: 4 nutlets, round and smooth. Preferred Habitat—Fields, roadsides, waste places. Flowering Season—May—October. Distribyution—North America, Europe, Asia. This humble, rusty green plant, weakly lopping over the sur- rounding grass, so that often only its insignificant purple, clover- like flower heads are visible, is another of those immigrants from the old countries which, having proved fittest in the fiercer struggle for existence there, has soon after its introduction here exceeded most of our more favored native flowers in numbers. Every- where we find the heal-all, sometimes dusty and stunted by the roadside, sometimes truly beautiful in its fresh purple, violet, and white when perfectly developed under happy conditions. In 45 From Blue to Purple England, where most flowers are deeper hued than with us, the heal-all is rich purple. What is the secret of this flower’s success- ful march across three continents? As usual, the chief reason is to be found in the facility it offers insects to secure food ; and the quantity of fertile seed it is therefore able to ripen as the result of their visits is its reward. Also, its flowering season is unusu- ally long, and it is a tireless bloomer. It is finical in no respect ; its sprawling stems root easily at the joints, and it is very hardy. Several species of bumblebees enter the flower, which being set in dense clusters enables them to suck the nectar from each with the minimum loss of time, the smaller bee spending about two seconds to each. After allowing for the fraction of time it takes him to sweep his eyes and the top of his head with his forelegs to free them from the pollen which must inevitably be shaken from the stamen in the arch of the corolla as he dives deeply after the nectar in the bottom of the throat, and to pass the pollen, just as honey-bees do, with the most amazing quickness, from the forelegs to the middle ones, and thence to the hair ‘basket’ on the hind ones—after making all allowances for suc delays, this small worker is able to fertilize all the flowers in the fullest cluster in halfa minute! When the contents of the baskets of two different species of bumblebees caught on this blossom were examined under the microscope, the pollen in one case proved to be heal-all, with some from the golden-rod, and a few grains of a third kind not identified ; and in the other case, heal-all pollen and a small proportion of some unknown kind. Bees that are evidently out for both nectar and pollen on the same trip have been detected visiting white and yellow flowers on their way from one heal-all cluster to another ; and this fact, together with the presence of more than one kind of pollen in the basket, shows that the generally accepted statement that bees confine them- selves to flowers of one kind or color during a trip is not always according to fact. The older name of the plant, Brunella, and the significant one, altered by Linnzus into the softer sound it now bears, is doubt- less derived from the German word, bradne, the quinsy. Quaint old Parkinson reads : ‘‘ This is generally called prunella and bru- nella from the Germans who called it brunellen, because it cureth that disease which they call die bruen, common to soldiers in campe, but especially in garrison, which is an inflammation of the mouth, throat, and tongue.” Among the old herbalists who pre- tended to cure every ill that flesh is heir to with it, it was various! known as carpenter’s herb, sicklewort, hook-heal, slough-heal, and brownwort. From Blue to Purple American or Mock Pennyroyal; Tickweed; Squaw Mint (Hedeoma pulegioides) Mint family Flowers—Very small, bluish purple, clustered in axils of upper leaves. Calyx tubular, unequally 5-cleft; teeth of upper lip triangular, hairy in throat. Corolla 2-lipped, upper lip erect, notched; lower one 3-cleft, spreading; 2 anther-bearing stamens under upper lip; 2 sterile but apparent; 1 pistil with 2-cleft style. Stem: Low, erect, branched, square, hairy, 6 to 18 in. high. Leaves: Small, opposite, ovate to oblong, scant- ily toothed, ey aromatic, pungent. Preferred Habitat—Dry fields, open woodland. Flowering Season—July—September. a eal Breton Island westward to Nebraska, south te orida. However insignificant its flower, this common little plant un- mistakably proclaims its presence throughout the neighborhood. So powerful is the pungent aroma of its leaves that dog doctors sprinkle them about freely in the kennels to kill fleas, a pest by no means exterminated in Southern Europe, however, where the true pennyroyal of commerce (Mentha Pulegium) is native. Herb gatherers who collect our pennyroyal, that is so similar to the Eu- ropean species it is similarly employed in medicine, say they can scent it from a greater distance than any other plant. Bastard Pennyroyal, which, like the Self-heal, is sometimes called Blue Curls (Trichostema dicholomum), chooses dry fields, but preferably sandy ones, where we find its abundant, tiny blue flowers, that later change to purple, from July to October. Its balsam-like odor is not agreeable, neither has the plant beauty to recommend it; yet where it grows, from Maine to Florida, and west to Texas, it is likely to be so common we cannot well pass it unnoticed. The low, stiff, slender, much-branched, and rather clammy stem bears opposite, oblong, smooth-edged leaves nar- rowed into petioles. One, two, or three flowers, borne at the tips of the branches, soon fall off, leaving the 5-cleft calyx to cradle four exposed nutlets. From the five-lobed tubular corolla protrude four very long, curling, blue or violet stamens—hair stamens the Greek generic title signifies—and the pretty popular name of blue curls also has ra to these conspicuous filaments that are spirally coiled in the bud. In general habit like the two preceding plants, the False Pene 47 From Blue to Purple nyroyal (/santhus brachiatus) nevertheless prefers that its sandy home should be near streams. From Quebec to Georgia, west- ward to Minnesota and Texas, it blooms in midsummer, lifting its small, tubular, pale-blue flowers from the axils of pointed, opposite leaves. An unusual characteristic in one of the mint tribe is that the five sharp lobes of its bell-shaped calyx, and the five rounded, spreading lobes of the corolla, are of equal length, hence its Greek name signifying an equal flower. Wild or Creeping Thyme (Thymus Serpylium) Mint family Flowers—Very small purple or pink purple, fragrant, clustered at ends of branches or in leaf axils. Hairy calyx and corolla 2- lipped, the latter with lower lip 3-cleft; stamens 4; style 2- cleft. Leaves: Oblong, opposite, aromatic. Stem: 4 to 12 in. long, creeping, woody, branched, forming dense cushions. Preferred Habitat—Roadsides, dry banks, and waste places. Flowering Season—June—September. Re ore from Europe. Nova Scotia to Middle tates. “1 know a bank where the wild thyme blows, Where oxlips and the nodding violet grows ; Quite over-canopied with luscious woodbine, With sweet musk-roses, and with eglantine.” —A Midsummer Night's Dream, According to Danish tradition, any one waiting by an elder- bush on Midsummer Night at twelve o’clock will see the king of fairyland and all his retinue pass by and disport themselves in favorite haunts, among others the mounds of fragrant wild thyme. How well Shakespeare knew his folk-lore! Thyme is said to have been one of the three plants which made the Virgin Mary’s bed. Indeed, the European peasants have as many myths as there are quotations from the poets about this classic plant. Its very name denotes that it was used as an in- cense in Greek temples. No doubt it was the Common Thyme (T. vulgaris), an erect, tall plant cultivated in gardens here as a savory, that Horace says the Romans used so extensively for bee culture. Dense cushions of creeping thyme usually contain two forms of blossoms on separate plants—hermaphrodite (male and female), which are much the commoner; and pistillate, or only female, flowers, in which the stamens develop no pollen. The latter are more fertile ; none can fertilize itself. But blossoms so rich in nectar naturally attract quantities of insects—bees and butterflies 48 From Blue to Purple chiefly. A newly opened hermaphrodite flower, male on the first day, dusts its visitors as they pass the ripe stamens. This pollen they carry to a flower two days old, which, having reached the female stage, receives it on the mature two-cleft stigma, now erect and tall, whereas the stamens are past maturity. Garden, Spear, or Mackerel Mint (Mentha spicata) Mint family (M. viridis of Gray) Flowers—Small, pale bluish, or pinkish purple, in whorls, forming terminal, interrupted, narrow spikes, 2 to 4 in. long in fruit, the central one surpassing lateral ones. Calyx bell-shaped, toothed; corolla tubular, 4-cleft. Stamens 4; style 2-cleft. Stem : Smooth, 1 to 1% ft. high, branched. Leaves ; Oppo- site, narrowly oblong, acute, saw-edged, aromatic. Preferred Habitat—Moist soil. Flowering Season—July—September. Distribution—Eastern half of Canada and United States. Also Europe and Asia. The poets tell us that Proserpine, Pluto’s wife, in a fit of Jaloey changed a hated rival into the mint plant, whose name entha, in its Latin form, or Minthe, the Greek equivalent, is still that of the metamorphosed beauty, a daughter of Cocytus, who was also Pluto’s wife. Proserpine certainly contrived to keep her rival’s memory fragrant. But how she must aeliant in seeing her under the chopping-knife and served up as sauce It is acurious fact that among the Labiates, or two-lipped blos- soms to which thymes and mints belong, there very frequentl occur species bearing flowers that are male on the first day (stami~ nate) and female, or pistillate, on the second day, and also srnaller female flowers on distinct plants. Miller believed this plan was devised to attract insects, first by the more showy hermaphrodite flower, that they might carry its pollen to the less conspicuous female flower, which they would naturally visit last; but this in- teresting theory has yet to be proved. Nineteen species of flies, to which the mints are specially adapted, have been taken in the act of transferring pollen. Ten varieties of the lower hymenoptera (bees, wasps, and others) commonly resort to the fragrant spikes of bloom. Peppermint (M. piperita), similar in manner of growth to the preceding, is another importation from Europe now thoroughly at home here in wet soil. The volatile oil obtained by distilling 49 From Blue to Purple its leaves has long been an important item of trade in Wayne County, New York. One has only to crush the leaves in one’s hand to name the flower. Ournative Wild Mint (M. Canadensis), common along brook- sides and in moist soil from New Brunswick to Virginia and far westward, has its whorls of small purplish flowers seated in the leaf axils. Its odor is like pennyroyal. The true pennyroyal, not to be confused with our spurious woodland annual, ts M. Pule- gium, a native of Europe, whence a number of its less valuable relatives, all perennials, have travelled to become naturalized Americans. In dry open woods and thickets and by the roadside, from late August throughout September, we find blooming the aromatic fragrant Stone Mint, Sweet Horse-mint, or American Dittany (Cuntla origanoides)—C. Mariana of Gray. Its small pink-pur- ple, lilac, or whitish flowers, that are only about half as long as the protruding pair of stamens, are borne in loose terminal clusters at the ends of the stiff, branched, slender, sometimes reddish, stem. A pair of rudimentary, useless stamens remain within the two- lipped tube; the exserted pair, affording the most convenient alighting place for the visiting flies, dust their under sides with pollen the first day the flower opens; on the next, the stigma will be ready to receive pollen carried from young flowers. Nightshade; Blue Bindweed; Felonwort; Bit- tersweet: Scarlet or Snake Berry; Poison- flower; Woody Nightshade (Solanum Dulcamara) Potato family Flowers—Blue, purple, or, rarely, white with greenish spots on each lobe; about % in. broad, clustered in slender, drooping cymes. Calyx 5-lobed, oblong, persistent on the berry; corolla deeply, sharply 5-cleft, wheel-shaped, or points curved back- ward; 5 stamens inserted on throat, yellow, protruding, the anthers united to form a cone; stigma small. Stem: Climb- ing or straggling, woody below, branched, 2 to 8 ft. long. Leaves: Alternate, 2 to 4 in. long, 1 to 2% in. wide, pointed at the apex, usually heart-shaped at base; some with 2 dis- tinct leaflets below on the petiole, others have leaflets united with leaf like lower lobes or wings. Fruit; A bright red, oval berry. Preferred Habitat—Moist thickets, fencerows. Flowering Season—May—September. 50 From Blue to Purple Distribution—United States east of Kansas, north of New Jersey. Canada, Europe, and Asia. More beautiful than the graceful flowers are the drooping cymes of bright berries, turning from green to yellow, then to orange and scarlet, in the tangled thicket by the shady roadside in autumn, when the unpretending, shrubby vine, that has crowded its way through the rank midsummer vegetation, becomes a joy to the eye. Another bittersweet, so-called, festoons the hedge- rows with yellow berries which, bursting, show their scarlet-coated seeds. Rose hips and mountain-ash berries, among many other conspicuous bits of color, arrest attention, but not for us were they designed. Now the birds are migrating, and, hungry with their long flight, they gladly stop to feed upon fare so attractive. Hard, indigestible seeds traverse the alimentary canal without alteration and are deposited many miles from the parent that bore them. Nature’s methods for widely distributing plants cannot but stir the dullest imagination. The purple pendent flowers of this nightshade secrete no nectar, therefore many insects let them alone; but it is now be- lieved that no part of the plant is poisonous. Certainly one that claims the potato, tomato, and egg-plant among its kin has no _ tight to be dangerous. The Black, Garden, or Deadly Nightshade, also called Morel (S. nigrum), bears jet-black berries that are alleged to be fatal. Nevertheless, female bumblebees, to whichits white flowers are specially adapted, visit them to draw out pollen from the chinks of the anthers with their jaws, just as they do in the case of the wild, sensitive plant, and with no more disastrous result. It has been well said that the nightshades are a blessing both to the sick and to the doctors. The present species takes its name from dulcis, sweet, and amaras, bitter, referring to the taste of the juice; the generic name is derived from solamen, solace or consolation, referring to the relief afforded by the nares cotic properties of some of these plants. Blue or Wild Toadflax; Blue Linaria (Linaria Canadensis) Figwort family Flowers—Pale blue to purple, small, irregular, in slender spikes. Calyx 5-pointed; corolla 2-lipped, with curved spur longer than its tube, which is nearly closed by a white, 2-ridged pro- jection or palate; the upper lip erect, 2-lobed; lower lip 3- lobed, spreading. Stamens 4, in pairs, in throat; 1 pistil. Stem: Slender, weak, of sterile shoots, prostrate; flowering stem, ascending or erect, 4 in. to 2 ft. high. Leaves: Small, linear, alternately scattered along stem, or oblong in pairs ot threes on leafy sterile shoots. 5 From Blue to Purple Preferred Habitat—Dry soil, gravel, or sand. Flowering Season—May—October. Distribution—North, Central, and South Americas. Sometimes lying prostrate in the dust, sometimes erect, the linaria’s delicate spikes of bloom wear an air of injured innocence; yet the plant, weak as it looks, has managed to spread over three Americas from ocean to ocean. More beautiful than the rather scrawny flowers are the tufts of cool green foliage made by the sterile shoots that take complete possession of a wide area around the parent plants. Unlike its relative butter-and-eggs, the corolla of this toadflax is so contracted that bees cannot enter it; but by inserting their long tongues, they nevertheless manage to drain it. Small, short- tongued bees contrive to reach only a little nectar. The palate, so valuable to the other linaria, has in this one Jost its function; and the larger flies, taking advantage of the flower’s weakness, pilfer both sweets and pollen. Butterflies, to which a slender- spurred flower is especially attractive, visit this one in great num- bers, and as they cannot regale themselves without touching the anthers and stigma, they may be regarded as the legitimate visitors. Wolf, rat, mouse, sow, cow, cat, snake, dragon, dog, toad, are among the many animal prefixes to the names of flowers that the English country people have given for various and often most in- teresting reasons. Just as dog, used as a prefix, expresses an idea of worthlessness to them, so toad suggests a spurious plant; the toadflax being made to bear what is meant to be an odious name because before flowering it resembles the true flax, /inum, from which the generic title is derived. Maryland Figwort; Bee Plant; Knotted Fig- wort; Heal-all; Pilewort (Scrophularia Marylandica) Figwort family (S. nodosa of Gray.) Flowers—Very small, dull green on outside ; vivid, shining brown- ish purple within ; borne in almost leafless terminal clusters on slender stems. Calyx 5-parted; corolla of 5 rounded lobes, the 2 upper ones erect, side ones ascending, lower one bent downward; 5 stamens, 4 of them twin-like and bearing anthers, the fifth sterile, a mere scale on roof of the globular corolla tube; style with knot-like stigma. Stem: From 3 to to ft. high, square, with grooved sides, widely branching. Leaves: From 3 to 12 in. long, oblong, pointed, coarsely toothed, on slender stems, strong smelling. 52 From Blue to Purple Preferred Habitat—Moist, shady ground. Flowering Season—)uly—September. Distribution—New York to the Carolinas, westward to Tennessee and Kansas; possibly beyond. An insignificant little flower by itself, conspicuous only because it rears itself in clusters on a level with one’s eyes, lack- ing beauty, perfume, and all that makes a blossom charming to the human mind—why has it been elevated by the botanists to the dignity of lending its name to a large and important family, and why is it mentioned at all in a popular flower book beside the more showy ornaments of nature’s garden? Both questions have the same answer: Because it is the typical flower of the family, and therefore serves as an illustration of the manner in which many others are fertilized. Beautiful blossoms are by no means always the most important ones. It well repays one to observe the relative times of matur- ing anthers and stigmas in the flowers, as thereby hangs a tale in which some insect plays an interesting réle. The figwort matures its stigma at the lip of the style before its anthers have ripened their pollen. Why? By having the stigma of a newly opened flower thrust forward to the mouth of the corolla, an insect alighting on the lip, which forms his only convenient landing place, must brush against it and leave upon it some pollen brought from an older flower, whose anthers are already matured. At this early stage of the flower’s development its stamens lie curved over in the tube of the corolla; but presently, as the already fertilized style begins to wither, and its stigma is dry and no longer receptive to pollen, then, since there can be no longer any fear of self-pollination—the horror of so many flowers—the figwort uncurls and elevates its stamens. The insect visitor in search of nectar must get dusted with pollen from the late maturing anthers now ready for him. By this ingenious method the flower becomes cross-fertilized and wastes the least pollen. Bees and wasps evidently pursue opposite routes in going to work, the former beginning at the bottom of a spike or raceme, where the older, more mature flowers are, and working upward; the wasps commencing at the top, among the newly opened ones. In spite of the fact that we usually see hive bees about this plant, pilfering the generous supply of nectar in each tiny cup, it 1s un- doubtedly the wasp that is the flower’s truest benefactor, since he carries pollen from the older blossoms of the last raceme visited to the projecting stigmas of the newly opened flowers at the top of the next cluster. Manifestly no flower, even though it were especially adapted to wasps, as this one is, could exclude bees. About one-third of all its visitors are wasps. 53 From Blue to Purple Hairy Beard-Tongue (Pentstemon hirsutus) Figwort family (P. pubescens of Gray) Flowers—Dull violet or lilac and white, about 1 in. long, borne ina loose spike. Calyx 5-parted, the sharply pointed sepals over- lapping; corolla, a gradually inflated tube widening where the mouth divides into a 2-lobed upper lip and a 3-lobed lower lip; the throat nedrly closed by hairy palate at base of lower lip; sterile fifth stamen densely bearded for half its length; 4 anther-bearing stamens, the anthers divergent. Sfem. 1 to 3 ft. high, erect, downy above. Leaves : Oblong to lance shape, upper ones seated on stem; lower ones narrowed into petioles. Preferred Habitat—Dry or rocky fields, thickets, and open woods. Flowering Season—May—July. Distribution—Ontario to Florida, Manitoba to Texas. It is the densely bearded, yellow, fifth stamen (pente = five, stemon = a stamen) which gives this flower its scientific name and its chief interest to the structural botanist. From the fact that a blossom has a lip in the centre of the lower half of its corolla, that an insect must use as its landing place, comes the necessity for the pistil to occupy a central position. Naturally, a fifth stamen would be only in its way, an encumbrance to be banished in time. In the figwort, for example, we have seen the fifth stamen reduced, from long sterility, to a mere scale on the roof of the corolla tube; in other lipped flowers, the useless organ has disappeared ; but in the beard-tongue, it goes through a series of curious curves from the upper to the under side of the flower to get out of the way of the pistil. Yet it serves an admirable purpose in helping close the mouth of the flower, which the hairy lip alone could not ade- quately guard against pilferers. A long-tongued bee, thrusting in his head up to his eyes only, receives the pollen in his face. The blossom is male (staminate) in its first stage and female (pistillate) in its second. While this is the beard-tongue commonly found in the Eastern United States, particularly southward, and one of the most beautiful of its clan, the western species have been selected by the gardeners for hybridizing into those more showy, but often less charming, flowers now quite extensively cultivated. Several varieties of these, having escaped from gardens in the East, are locally common wild. The Large-flowered Beard-tongue (P. grandiflorus), one of the finest prairie species, whose lavender-blue, bell-shaped corolla 54 From Blue to Purple is abruptly dilated above the calyx, measures nearly two inches long. Its sterile filament, curved over at the summit, is bearded there only. Handsomest of all is the Cobea Beard-tongue, a native of the Southwest, with a broadly rounded, bell-shaped corolla, hai without, like the leaves, but smooth within. The pale purple blossom, delicately suffused with yellow, and pencilled with red lines—pathfinders for the bees—has the base of its tube creamy white. Few flowers hang from each stout clammy spike. The more densely crowded spikes of the large Smooth Beard-tongue (P. glaber), a smaller blue or purple flowered, narrower-leaved species, that shows an unusual preference for moist soil throughout its range, is, like the other beard-tongues mentioned, better known to the British gardener, perhaps, than to Americans, who have yet to learn the value of many of their wild flowers under cultivation. The tall Foxglove Beard-tongue (P. digitalis), with large, showy white blossoms tinged with purple, the one most com- monly grown in gardens here, escapes on the slightest encourage- ment to run wild again from Maine to Virginia, west to Illinois and Arkansas. Small bees crawl into the broad tube, and butter- flies drain the nectar evidently secreted for long-tongued bees, but without certainly transferring pollen. To insure cross-fertili- zation, the flower first develops its anthers, whose saw-edges grating against the visitor’s thorax, aid in sifting out the dry pollen; and later the style, which when immature clung to the top of the corolla, lowers its receptive stigma to oppose the bee’s entrance. Professor Robertson has frequently detected the com- mon wasp nipping holes with her sharp jaws in the base of the tube. With remarkable intelligence she invariably chose to insert her tongue at the precise spots where the nectar is stored on either side of the sterile filament. Blue-eyed Mary; Innocence; Broad-leaved Collinsia (Collinsia verna) Figwort family Flowers—On slender, weak stalks ; whorled in axils of upper leaves. Blue on lower lip of corolla, its middle lobe folded lengthwise to enclose 4 adhering stamens and 1 pistil; upper lip white, with scalloped margins; corolla from % to % in. long, its throat about equalling the deeply 5-cleft calyx. Stem: Hoary, 55 From Blue to Purple slender, simple or branched, from 6 in. to 2 ft. high. Leaves: Thin, opposite; upper and more acute ones clasping the stem; lower, ovate ones on short petioles. Fruzt: Around capsule to which the enlarged calyx adheres. Preferred Habitat—Moist meadows, woods, and thickets. Flowering Season—April—June. Distribution—Western New York and Pennsylvania to Wisconsin, Kentucky, and Indian Territory. Next of kin to the great Paulonia tree, whose deliciously sweet, vanilla-scented, trumpet-shaped violet flowers are happily fast becoming as common here as in their native Japan, what hay this fragile, odorless blossom of the meadows in common with it? Apparently nothing ; but superficial appearances count for little or nothing among scientists, to whom the structure of floral organs is of prime importance ; and analysis instantly shows the close relationship between these dissimilar-looking cousins. Even with- out analysis one can readily see that the monkey flower is not far removed. Because few writers have arisen as yet in the newly settled regions of the middle West and Southwest, where blue-eyed Mary dyes acres of meadow land with her heavenly color, her praises are little sung in the books, but are loudly buzzed by myriads of bees that are her most devoted lovers. ‘‘I regard the flower as especially adapted to the early flying bees with abdom- inal collecting brushes for pollen—z.e., species of Osmza—and these bees,”’ says Professor Robertson of Illinois, ‘‘ although not the exclusive visitors, are far more abundant and important than all the other visitors together.” For them are the brownish marks on the palate provided as pathfinders. At the pressure of their strong heads the palate yields to give them entrance, and at their removal it springs back to protect the pollen against the inroads of flies, mining bees, and beetles. As the longer stamens shed their pollen before the shorter ones mature theirs, bees must visit the flower several times to collect it all. Monkey-flower (Minulus ringens) Figwort family Flowers—Purple, violet, or lilac, rarely whitish; about 1 in. long, solitary, borne on slender footstems from axils of uppef leaves. Calyx prismatic, 5-angled, 5-toothed; corolla irregu- lar, tubular, narrow in throat, 2-lipped; upper lip 2-lobed, erect; under lip 3-lobed, spreading; 4 stamens, a long anda short pair, inserted on corolla tube; 1 pistil with 2-lobed, plate-like stigma. Stem: Square, erect, usually branched, I 56 From Blue to Purple to 3 feet high. Leaves: Opposite, oblong to lance-shaped, saw-edged, mostly seated on stem. Preferred Habitat—Swamps, beside streams and ponds. Hlowering Season—June—September. tie toe Mantas, Nebraska, and Texas, eastward to Atlantic . Ocean. No wader is the square-stemmed Monkey-flower whose grin- ning corolla peers at one from grassy tuffets in swamps, from the brookside, the springy soil of low meadows, and damp hollows beside the road; but moisture it must have to fill its nectary and to soften the ground for the easier transit of its creeping rootstock. Imaginative eyes see what appears to them the gaping (ringens) face of a little ape or buffoon (mimulus) in this common flower whose drolleries, such as they are, call forth the only applause desired—the buzz of insects that become pollen-laden during the entertainment. Now the advanced stigma of this flower is peculiarly irritable, and closes up on contact with an incoming visitor’s body, thus exposing the pollen-laden anthers behind it, and, except in rare cases, preventing self-fertilization. Delpino was the first to guess what advantage so sensitive a stigma might mean. Probably the smaller bees find the tube too long for their short tongues. The yellow palate, which partially guards the entrance to the nec- tary from pilferers, of course serves also as a pathfinder to the long-tongued bees. American Brooklime (Veronica Americana) Figwort family Flowers—Light blue to white, usually striped with deep blue or purple ; structure of flower similar to that of V. officinalis, but borne in long, loose racemes branching outward on stems that spring from axils of most of the leaves. Stem: With- out hairs, usually branched, 6 in. to 3 ft. long, lying partly on ground and rooting from lower joints. Leaves: Oblong, lance-shaped, saw-edged, opposite, petioled, and lacking hairs ; 1 to 3in. long, 4% to1in. wide. Fruzt: A nearly round, compressed, but not flat, capsule with flat seeds in 2 cells. Preferred Habitat—\n brooks, ponds, ditches, swamps. Flowering Season—April—September. Distribution—From Atlantic to Pacific, Alaska to California and New Mexico, Quebec to Pennsylvania. This, the perhaps most beautiful native speedwell, whose sheets of blue along the brookside are so frequently mistaken for 57 From Biue to Purple masses of forget-me-nots by the hasty observer, of course shows marked differences on closer investigation ; its tiny blue flowers are marked with purple pathfinders, and the plant is not hairy, to mention only two. But the poets of England are responsible for most of whatever confusion stills lurks in the popular mind con- cerning these two flowers. Speedwell, a common medizval benediction from a friend, equivalent to our farewell or adieu, and forget-me-not of similar intent, have been used interchangeably by some writers in connection with parting gifts of small blue flowers. It was the germander speedwell that in literature and botanies alike was most commonly known as the forget-me-not for over two hundred years, or until only fifty years ago. When the ‘‘ Mayflower” and her sister ships were launched, ‘‘ Speed- wel ” was considered a happier name for a vessel than it proved to be. The Water Speedwell, or Pimpernel (V. Anagallis-aquatica), differs from the preceding chiefly in having most of its leaves seated on the stalk, only the lower ones possessing stems, and those short ones. In autumn the increased growth of sterile shoots from runners produce almost circular leaves, often two inches broad, a certain aid to identification. Another close relation, the Marsh or Skullcap Speedwell (V. scutellata), on the other hand, has long, very slender, acute leaves, their teeth far apart; and as these three species are the only members of their clan likely to be found in watery places within our limits, a close examination of the leaves of any water- loving plant bearing small four-lobed blue flowers, usually marked with lines of a deeper blue or purple, should enable one to correctly name the species. None of these blossoms can be carried far after being picked; they have a tantalizing habit of dropping off, leaving a bouquet of tiny green calices chiefly. Many kinds of bees, wasps, flies, and butterflies fertilize all these little flowers, which are first staminate, then pistillate, simply by crawling over them in search of nectar. Common Speedwell; Fluellin; Paul’s Betony; Ground-hele (Veronica officinalis) Figwort family Flowers—Pale blue, very small, crowded on spike-like racemes from axils of leaves, often from alternate axils. Calyx 4-parted; corolla of 4 lobes, lower lobe commonly narrowest ; 2 di- vergent stamens inserted at base and on either side of uppet 58 From Blue to Purple corolla lobe ; a knob-like stigma on solitary pistil. Stem: From 3 to 10 in. long, hairy, often prostrate, and rooting at joints. Leaves: Opposite, oblong, obtuse, saw-edged, nar- towed at base. Fruit: Compressed heart-shaped capsule, containing numerous flat seeds. Preferred Habitat—Dry fields, uplands, open woods. Flowering Season—May—August. Distribution—From Michigan and Tennessee eastward, also from are to Nova Scotia. Probably an immigrant from Europe and Asia. An ancient tradition of the Roman Church relates that when Jesus was on His way to Calvary, He passed the home of a certain Jewish maiden, who, when she saw the drops of agony on His brow, ran after Him along the road to wipe His face with her kerchief. This linen, the monks declared, ever after bore the impress of the sacred features—vera iconica, the true likeness. When the Church wished to canonize the pitying maiden, an abbreviated form of the Latin words was given her, St. Veronica, and her kerchief became one of the most precious relics at St. Peter’s, where it is said to be still preserved. Medieval flower lovers, whose piety seems to have been eclipsed only by their imaginations, named this little flower from a fancied resemblance to the relic. Of course, special healing virtue was attributed to the square of pictured linen, and since all could not go to Rome to be cured by it, naturally the next step was to employ the common, wayside plant that bore the saint’s name. Mental healers will not be surprised to learn that because of the strong popular belief in its efficacy to cure all fleshly ills, it actually seemed to possess miracu- lous powers. For scrofula it was said to be the infallible remedy, and presently we find Linnzus grouping this flower, and all its relatives under the family name of Scrofulariacee. ‘‘What’sina name?” Religion, theology, medicine, folk-lore, metaphysics, what not? One of the most common wild flowers in England is this same familiar little blossom of that lovely shade of blue known by Chinese artists as ‘‘the sky after rain.” ‘‘ The prettiest of all humble roadside flowers I saw,” says Burroughs, in ‘‘ A Glance at British Wild Flowers.” ‘‘It is prettier than the violet, and larger and deeper colored them our houstonia. It is a small and delicate edition of our hepatica, done in indigo blue, and wonted to the grass in the fields and by the waysides. ‘The little speedwell’s darling blue” sings Tennyson. I saw it blooming with the daisy and _butter- cup upon the grave of Carlyle. The tender human and poetic element of his stern, rocky nature was well expressed by it.” Only as it grows in masses is the speedwell conspicuous—2 From Blue to Purple sufficient reason for its habit of forming colonies and of gathering its insignificant blossoms together into dense spikes, since by these methods it issues a flaunting advertisement of its nectar. The flower that simplifies dining for insects has its certain reward in rapidly increased and vigorous descendants. To save repetition, the reader interested in the process of fertilization is referred to the account of the Maryland figwort, since many members of the large family to which both belong employ the same method of economizing pollen and insuring fertileseed. In this case visitors have only to crawl over the tiny blossoms. From Labrador to Alaska, throughout almost every section of the United States, in South America, Europe, and Asia, roams the Thyme-leaved Speedwell (V. serpyliifolia), by the help of its numerous flat seeds, that are easily transported on the wind, and by its branching stem, that lies partly on the ground, rooting where the joints touch earth. The small oval leaves, barely half an inch long, grow in pairs. The tiny blue, or sometimes white, flowers, with dark pathfinders to the nectary, are borne on spike-like racemes at the ends of the stem and branches that rear themselves upward in fields and thickets to display their bloom before the passing bee. Pale, or Naked, or One-flowered Broom- rape (Thalesia uniflora) Broom-rape family (Aphylion uniflorum of Gray) Flowers—Violet, rarely white, delicately fragrant, solitary at end of erect, glandular peduncles. Calyx hairy, bell-shaped, 5-toothed, not half the length of corolla, which is 1 in. or less long, with curved tube spreading into 2 lips, 5-lobed, yellow-bearded within ; 4 stamens, in pairs, inserted on tube of corolla; 1 pistil. Stem: About 1 in. long, scaly, often entirely underground; the 1 to 4 brownish scape-like pe- duncles, on which flowers are borne, from 3 to 8 in. high. Leaves: None. Fruit; An elongated, egg-shaped, 1-celled capsule containing numerous seeds. Preferred Habitat—Damp woods and thickets. Flowering Season—April—June. Distribution—British Possessions and United States from coast to coast, southward to Virginia, and Texas. A curious, beautiful parasite, fastened on the roots of honest plants from which it draws its nourishment. The ancestors 60 From Blue to Purple of this species, having deserted the path of rectitude ages ago to live by piracy, gradually lost the use of their leaves, upon which virtuous plants depend as upon a part of their digestive apparatus ; they grew smaller and smaller, shrivelled and dried, until now that the one-flowered broom-rape sucks its food, rendered already digestible through another’s assimilation, no leaves remain on its brownish scapes. Disuse of any talent in the vegetable kingdom, as in the spiritual, leads to inevitable loss: ‘‘ Unto every one which hath shall be given ; and from him that hath not, even that he hath shall be taken away.” Hairy Ruellia (Ruellia ciliosa) Acanthus family Flowers—Pale violet blue, showy, about 2 in. long, ey or clustered in the axils or at the end of stem. Calyx of 5 bris- tle-shaped hairy segments; corolla with very slender tube ex- panding above in 5 nearly equal obtuse lobes; stamens 4; 1 pistil with recurved style. Stem: Hairy, especially above, erect, I to 2% ft. high. Leaves: Opposite, oblong, narrowed at apex, entire, covered with soft white hairs. Perferred Habitat—Dry soil. Flowering Season—June—September. Distribution—New Jersey southward to the Gulf and westward to Michigan and Nebraska. Many charming ruellias from the tropics adorn hothouses and window gardens in winter; but so far north as the New Jer- sey pine barrens, and westward where killing frosts occur, this oa proves to be perfectly hardy. In addition to its showy lossoms, which so successfully invite insects to transfer their pol- len, thereby counteracting the bad effects of close in-breeding, the lant bears inconspicuous cleistogamous or blind ones also. hese look like arrested buds that never open; but, being fertilized with their own pollen, ripen abundant seed nevertheless. One frequently finds holes bitten in these flowers, as in so many others long of tube or spur. Bumblebees, among the most intelligent and mischievous of insects, are apt to be the chief of- fenders; but wasps are guilty too, and the female carpenter bee, which ordinarily slits holes to extract nectar, has been detected in the act of removing circular pieces of the corolla from this ruel- lia with which to plug up a thimble-shaped tube in some decayed tree. Here she deposits an egg on top of a layer of baby food, consisting of a paste of pollen and nectar, and seals up the nursery with another bit of leaf or flower, repeating the process until the long tunnel is filled with eggs and food for larve. Then she dies, Jeaving her entire race apparently extinct, and living only in eme 61 From Blue to Purple bryo for months. This is the bee which commonly cuts her round plugs from rose leaves. The Smooth Ruellia (R. strepens), an earlier bloomer than the preceding, and with a more southerly range, has a_ shorter, thicker tube to its handsome blue flower, and lacks the hairs which guard its relative from crawling pilferers. Biuets: Innocence; Houstonia; Quaker Ladies; Quaker Bonnets: Venus’ Pride (Houstonia coerulea) Madder family Flowers—Very small, light to purplish blue or white, with yellow centre, and borne at end of each erect slender stem that rises from 3 to 7 in. high. Corolla funnel-shaped, with 4 oval, pointed, spreading lobes that equal the slender tube in length; rarely the corolla has more divisions; 4 stamens in- serted on tube of corolla; 2 stigmas; calyx 4-lobed. Leaves: Opposite, seated on stem, oblong, tiny; the lower ones spatu- late. Fruit: A 2-lobed pod, broader than long, its upper half free from calyx; seeds deeply concave. Rootstock: Slen- der, spreading, forming dense tufts. Preferred Habitat—Moist meadows, wet rocks and banks. Flowering Season—April—July, or sparsely through summer. Distribution—Eastern Canada and United States west to Michigan, south to Georgia and Alabama. Millions of these dainty wee flowers, scattered through the grass of moist meadows and by the wayside, reflect the blue and the serenity of heaven in their pure, upturned faces. Where the white variety grows, one might think a light snowfall had powdered the grass, or a milky way of tiny floral stars had streaked a terrestrial path. Linnzus named the flower for Dr. Houston, a young English physician, botanist, and collector, who died in South America in 1733, after an exhausting tramp about the Gulf of Mexico. To secure cross-fertilization, the object toward which so much marvellous fioral organism is directed, this little plant puts forth two forms of blossoms—one with the stamens in the lower portion of the corolla tube, and the stigmas exserted; the other form with the stigmas below, and the stamens elevated to the mouth of the corolla. But the two kinds do not grow in the same patch, seed from either producing after its kind. Many insects visit these blossoms, but chiefly small bees and butter- flies. Conspicuous among the latter is the common little meadow fritillary (Brenthis bellona), whose tawny, dark-speckled wings 62 From Blue to Purple’ expand and close in apparent ecstasy as he tastes the tiny drop of nectar in each dainty enamelled cup. Coming to feast with his tongue dusted from anthers nearest the nectary, he pollenizes the large stigmas of a short-styled blossom without touching its tall anthers. But it is evident that he could not be depended on to fertilize the long-styled form, with its smaller stigma, because of this ability to insert his slender tongue from the side where it avoids contact. Flies and beetles enter the blossoms, but small bees are best adapted as all-round benefactors. This simple-look- ing blossom, that measures barely half an inch across, is clever enough to multiply its lovely species a thousand fold, while many a larger, and therefore one might suppose a wiser, flower dwindles toward extinction. John Burroughs found a single bluet in blossom one January, near Washington, when the clump of earth on which it grew was frozen solid. A pot of roots gathered in autumn and placed in a sunny window has sent up a little colony of star-like flowers throughout a winter. : Wild, Common, or Card Teazel; Gypsy Combs (Dipsacus sylvestris) Teazel family Flowers—Purple or lilac, small, packed in dense, cylindric heads, 3 to 4in. long; growing singly on ends of footstalks, the flowers set among stiffly pointed, slender scales. Calyx cup-shaped, 4-toothed. Corolla 4-lobed; stamens 4; leaves of involucre, slender, bristled, curved upward as high as flower-head or beyond. Stems: 3 to 6 ft. high, stout, branched, leafy, with numerous short prickles. Leaves: Opposite, lance-shaped, seated on stem, with bristles along the stout midrib. Preferred Habitat—Roadsides and waste places. Flowering Season—July—September. Distribution—Maine to Virginia, westward to Ontario and the Mississippi. Europe and Asia. Manufacturers find that no invention can equal the naturat teazel head for raising a nap on woollen cloth, because it breaks at any serious obstruction, whereas a metal substitute, in such a case, tears the material. Accordingly, the plant is largely culti- vated in the west of England, and quantities that have been im- ported from France and Germany may be seen in wagons on the way to the factories in any of the woollen-trade towns. After the flower-heads wither, the stems are cut about eight inches long, stripped of prickles, to provide a handle, and after drying, the natu- ral tool is ready for use. Bristling with armor, the teazel is not often attacked by brows- 63 From Blue to Purple ing cattle. Occasionally even the upper leaf surfaces .are dotted over with prickles enough to tear a tender tongue. This is a curious feature, for prickles usually grow out of veins. In the receptacle formed where the bases of the upper leaves grow to- gether, rain and dew are found collected—a certain cure for warts, country people say. Venus’ Cup, Bath, or Basin, and Water Thistle, are a few of the teazel’s folk names earned by its curious little tank. In it many small insects are drowned, and these are supposed to contribute nourishment to the plant; for Mr. Francis Darwin has noted that protoplasmic filaments reach out into the liquid. Owing to the stiff spines which radiate from the flower clus- ter, the bumblebees, which principally fertilize it, can reach the florets only with their heads, and not pollenize them by merely crawling over them as in the true composite. But by first matur- ing its anthers, then when they have shed their pollen, elevating its stigmas, the teazel prevents self-fertilization. Harebell or Hairbell; Blue Bells of Scotland; Lady’s Thimble (Campanula rotundifolia) Bellflower family Flowers—Bright blue or violet blue, bell-shaped, % in. long or over, drooping from hair-like stalks. Calyx of 5-pointed, narrow, spreading lobes ; 5 slender stamens alternate with lobes of corolla, and borne on summit of calyx tube, which is adherent to ovary; 1 pistil with 3 stigmas in maturity only. Siem: Very slender, 6 in. to 3 ft. high, often several from same root; simple or branching. Leaves: Lower ones nearly round, usually withered and gone by flowering sea- son; stem leaves narrow, pointed, seated onstem. Fruit: An egg-shaped, pendent, 3-celled capsule with short openings near base; seeds very numerous, tiny. Preferred Habttat—Moist rocks, uplands. Flowering Season—June—September. Distribution—Arctic regions of Europe, Asia, and America; south- ward on this continent, through Canada to New Jersey and Pennsylvania; westward to Nebraska, to Arizona in the Rockies, and to California in the Sierra Nevadas. The inaccessible crevice of a precipice, moist rocks sprayed with the dashing waters of a lake or some tumbling mountain stream, wind-swept upland meadows, and shady places by the roadside may hold bright bunches of these hardy bells, swaying with exquisite grace on tremulous, hair-like stems that are fitted to withstand the fiercest mountain blasts, however frail they appear. 64 From Blue to Purple How dainty, slender, tempting these little flowers are! One gladly risks a watery grave or broken bones to bring down a bunch from its aérial cranny. It was a long stride forward in the evolutionary scale when the harebell welded its five once separate petals together; first at the base, then farther and farther up the sides, until a solid _bell- shaped structure resulted. This arrangement which makes insect fertilization a more certain process because none of the pollen is lost through apertures, and because the visitor must enter the flower only at the vital point where the stigmas come in contact with his pollen-laden body, has given to all the flowers that have attained to it, marked ascendency. Like most inverted blossoms, the harebell hangs its head to protect its nectar and pollen, not only from rain, but from the in- trusion of undesirable crawling insects which would simply brush off its pollen in the grass before reaching the pistil of another flower, and so defeat cross-fertilization, the end and aim of so many blossoms. Advertising for winged insects by its bright color, the harebell attracts bees, butterflies, and many others. These visitors cannot well walk on the upright petals, and sooner or later must clasp the pistil if they would secure the nectar secreted at the base. In doing so, they will dust themselves and the imma- ture pistil with the pollen from the surrounding anthers; but a newly opened flower is incapable of fertilization. The pollen, although partially discharged in the unopened bud, is prevented from falling out by a coat of hairs on the upper part of the style. By the time all the pollen has been removed by visitors, however, and the stamens which matured early have withered, the pistil has grown longer, until it looks like the clapper in a bell; the stigma at its top has separated into three horizontal lobes which, being sticky on the under side, a pollen-laden insect on entering the bell must certainly brush against them and render them fertile. But humblebees, its chief benefactors, and others may not have done their duty by the flower; what then? Why, the stigmas in that case finally bend backward to reach the left-over pollen, and fertilize themselves, obviously the next best thing for them to do. How one’s reverence increases when one begins to understand, be it ever so little of, the divine plan! ‘*Probably the most striking blie and purple wild flowers we have,” says John Burroughs, ‘‘ are of European origin. These colors, except with the fall asters and gentians, seem rather un- stable in our flora.” This theory is certainly borne out in the case of the Rampion, European, or Creeping Bellflower (C. rapun- culotdes), now detected in the act of escaping from gardens from New Brunswick to Ontario, Southern New York, Pennsylvania, and Ohio, and making itself very much at home in our fields and along the waysides. Compared with the delicate little harebell, itis 5 65 From Blue to Purple a plant of rank, rigid habit. Its erect, rather stout stem, set with elongated oval, hairy, alternate leaves, and crowned with a one- sided raceme of widely expanded, purple-blue bells rising about two feet above the ground, has little of the exquisite grace of its cousin. It blooms from July to September. This is the species whose roots are eaten by the omnivorous European peasant. One of the few native campanulas, the Tall Bellflower (C. Americana), waves long, slender wands studded with blue or sometimes whitish flowers high above the ground of moist thickets and woods throughout the eastern half of this country, but rarely near the sea. Doubtless the salt air, which intensifies the color of so many flowers, would brighten its rather slatey blue. The corolla, which is flat, round, about an inch across, and deeply cleft into five pointed petals, has the effect of a miniature pinwheel in motion. Mature flowers have the style elongated, bent down- ward, then curved upward, that the stigmas may certainly be in the way of the visiting insect pollen-laden from an_ earlier bloomer, and be cross-fertilized. The larger bees, its benefactors, which visit it for nectar, touch only the upper side of the style, on which they must alight ; but the anthers waste pollen by shedding it on all sides. No insect can take shelter from rain or pass the night in this flower, as he frequently does in its more hospitable relative, the harebell. English gardeners, more appre- ciative than our own of our native flora, frequently utilize this charming plant in their rockwork, increasing their stock by a division of the dense, leafy rosettes. Venus’ Looking-glass; Clasping Bellflower (Legouzia perfoliata) Bellflower family (Specularia perfoliata of Gray) Flowers—Violet blue, from 3% to 34 in. across ; solitary or 2 or 3 together, seated, in axils of upper leaves. Calyx lobes vary- ing from 3 to 5 in earlier and later flowers, acute, rigid ; corolla a 5-spoked wheel ; 5 stamens; 1 pistil with 3 stig- mas. Siem: 6 in. to 2 ft. long, hairy, densely leafy, slender, weak. Leaves: Round, clasped about stem by heart-shaped base. Preferred Habitat—Sterile waste places, dry woods. Flowering Season—May—September. Distribution—From British Columbia, Oregon, and Mexico, east to Atlantic Ocean. At the top of a gradually lengthened and apparently over- burdened leafy stalk, weakly leaning upon surrounding vegeta- 66 SELF-HEAL OR BLUE CURLS OR SUCCORY CHICORY From Blue to Purple tion, a few perfect blossoms spread their violet wheels, while below them insignificant earlier flowers, which, although they have never opened, nor reared their heads above the hollows of the little shell-like leaves where they lie secluded, have, never- theless, been producing seed without imported pollen while their showy sisters slept. But the later blooms, by attracting insects, set cross-fertilized seed to counteract any evil tendencies that might weaken the species if it depended upon self-fertiliza- tion only. When the European Venus’ looking-glass used to be cultivated in gardens here, our grandmothers tell us it was alto- gether too prolific, crowding out of existence its less fruitful, bu* more lovely, neighbors. The Small Venus’ Looking-glass (L. biflora), of similar habit to the preceding, but with egg-shaped or oblong leaves seated on, not clasping, its smooth and very slender stem, grows in the South and westward to California. Great Lobelia; Blue Cardinal-flower (Lobelia syphilitica) Bellflower family flowers—Bright blue, touched with white, fading to pale blue, about 1 in. long, borne on tall, erect, leafy spike. Calyx 5- parted, the lobes sharply cut, hairy. Corolla tubular, open to base on one side, 2-lipped, irregularly 5-lobed, the petals pro- nounced at maturity only. Stamens 5, united by their hairy anthers into a tube around the style; larger anthers smooth. Stem: 1 to 3 ft. high, stout, simple, leafy, slightly hairy. Leaves: Alternate, oblong, tapering, pointed, irregularly toothed, 2 to 6 in. long, § to2in. wide. Preferred Habitat—Moist or wet soil; beside streams. Flowering Season—July—October. Distribution—Ontario and northern United States west to Dakota, south to Kansas and Georgia. To the evolutionist, ever on the lookout for connecting links, the lobelias form an interesting group, because their corolla, slit down the upper side and somewhat flattened, shows the begin- ning of the tendency toward the strap or ray flowers that are nearly confined to the composites of much later development, of course, than tubular single blossoms. Next to massing their flowers in showy heads, as the composites do, the lobelias have the almost equally advantageous plan of crowding theirs along a stem so as to make a conspicuous advertisement to attract the passing bee and to offer him the special inducement of numerous feeding places close together. The handsome Great Lobelia, constantly and invidiously come 67 From Blue to Purple pared with its gorgeous sister the cardinal flower, suffers un- fairly. When asked what his favorite color was, Eugene Field replied: ‘‘ Why, I like any color at all so long as it’s red!” Most men, at least, agree with him, and certainly humming-birds do; our scarcity of red flowers being due, we must believe, to the scarcity of humming-birds, which chiefly fertilize them. But how bees love the blue blossoms! There are many cases where the pistil of a flower necessarily comes in contact with its own pollen, yet fertilization does not take place, however improbable this may appear. Most orchids, for example, are not susceptible to their own pollen. It would seem as if our lobelia, in elevating its stigma through the ring formed by the united anthers, must come in contact with some of the pollen they have previously discharged from their tips, not only on the bumblebee that shakes it out of them when he jars the flower, but also within the tube. But when the anthers are mature, the two lobes of the still immature stigma are pressed together, and cannot be fertilized. Nevertheless, the hairy tips of some of the anthers brush off the pollen grains that may have lodged on the stigma as it passes through the ring in its ascent, thus making surety doubly sure. Only after the stigma projects beyond the ring of anthers does it expand its lobes, which are now ready to receive pollen brought from another later flower by the incoming bumblebee to which it is adapted. Linnzus named this group of plants for Matthias de I’Obel, a Flemish botanist, or herbalist more likely, who became physician to James I. of England. Preferably in dry, sandy soil or in meadows, and over a wide range, the slender, straight shoots of Pale Spiked Lobelia (L. spi- cata) bloom early and throughout the summer months, the in- florescence itself sometimes reaching a height of two feet. At the base of the plant there is usually a tuft of broadly oblong leaves; those higher up narrow first into spoon-shaped, then into pointed, bracts, along the thick and gradually lengthened spike of scattered bloom. The flowers are often pale enough to be called white. Like their relatives, they first ripen their anthers to prevent self-fertilization. The lithe, graceful little Brook Lobelia (L. Kalmiz), whose light-blue flowers, at the end of thread-like footstems, form a loose raceme, sways with a company of its fellows among the grass on wet banks, beside meadow runnels and brooks, particularly in limestone soil, from Nova Scotia to the Northwest Territory and southward to New Jersey. It bears an insignificant capsule, not inflated like the Indian tobacco’s; and long, narrow, spoon-shaped leaves. Twenty inches is the greatest height this little plant may hope to attain. 68 from Blue to Purple Not only beside water, and in it, but often totally immersed, grows the Water Lobelia or Gladiole (L. Dortmanna). The slender, hollow, smooth stem rises from a submerged tuft of round, hol- low, fleshy leaves longitudinally divided by a partition, and bears at the top a scattered array of pale-blue flowers from August to September. Indian or Wild Tobacco: Gag-root; Asthma- weed; Bladder-pod Lobelia (Lobelia inflata) Bellflower family Flowers—Pale blue or violet, small, borne at short intervals in spike-like leafy racemes. Calyx 5-parted, its awl-shaped lobes % in. long, or as long as the tubular, 2-lipped, 5-cleft, corolla that opens to base of tube on upper side. Stamens, 5 united by their hairy anthers into a ring around the 2-lobed style. Stem: From 1 to 3 feet high, hairy, very acrid, much branched, leafy. Leaves: Alternate, oblong or ovate, toothed, the upper ones acute, seated on stem; lower ones obtuse, petioled, I to 2% in. long. Fruit: A much inflated, rounded, ribbed, many seeded capsule. Preferred Habitat—Dry fields and thickets; poor soil. Flowering Season—July—November. Distribution—Labrador westward to the Missouri River, south to Arkansas and Georgia. The most stupid of the lower animals knows enough to let this poisonous, acrid plant alone; but not so man, who formerly made a quack medicine from it in the days when a drug that set one’s internal organism on fire was supposed to be especially beneficial. One taste of the plant gives a realizing sense of its value as an emetic. How the red man enjoyed smoking and chewing the bitter leaves, except for the drowsiness that followed, is a mystery. On account of the smallness of its flowers and their scanti- ness, the Indian tobacco is perhaps the least attractive of the lobe- lias, none of which has so inflated a seed vessel, the distinguish- ing characteristic of this common plant. Chicory: Succory; Blue Sailors; Bunk (Cichorium Intybus) Chicory family Flower-head—Bright, deep azure to gray blue, rarely pinkish or white, 1 to 1% in. broad, set close to stem, often in small clusters for nearly the entire length; each head a composite 69 From Blue to Purple of ray flowers only, 5-toothed at upper edge, and set in a flat green receptacle. Stem: Rigid, branching, 1 to 3 ft. high. Leaves: Lower ones spreading on ground, 3 to 6 in. long, spatulate, with deeply cut or irregular edges, narrowed into petioles, from a deep tap-root ; upper leaves of stem and branches minute, bract-like. Preferred Habitat—Roadsides, waste places, fields. Flowering Season—July—October. Distribuon—Common in Eastern United States and Canada, south to the Carolinas ; also sparingly westward to Nebraska. At least the dried and ground root of this European invader is known to hosts of people who buy it undisguised or not, accord- ing as they count it an improvement to their coffee or a disagreea- ble adulterant. So great is the demand for chicory that, notwith- standing its cheapness, it is often in its turn adulterated with roasted wheat, rye, acorns, and carrots. Forced and blanched ina warm, dark place, the bitter leaves find a ready market as a salad known as ‘‘barbe de Capucin” by the fanciful French. Endive and dandelion, the chicory’s relatives, appear on the table too, in spring, where people have learned the possibilities of salads, as they certainly have in Europe. From the depth to which the tap-root penetrates, it is not un- likely the succory derived its name from the Latin succurrere = to run under. The Arabic name chicourey testifies to the almost universal influence of Arabian physicians and writers in Europe after the Conquest. As chicorée, achicoria, chicoria, cicorea, chicorte, cichoret, cikorie, tsikoret, and cicorie the plant is known respectively to the French, Spanish, Portuguese, Italians, Germans, Dutch, Swedes, Russians, and Danes. On cloudy days or in the morning only throughout midsum- mer the ‘‘ peasant posy” opens its ‘‘ dear blue eyes” *“Where tired feet Toil to and fro ; Where flaunting Sin May see thy heavenly hue, Or weary Sorrow look from thee Toward a tenderer blue !” —Marcaret DELAND. In his ‘‘ Humble Bee” Emerson, too, sees only beauty in the **Succory to match the sky ;” but, mdirabile dictu, Vergil, rarely caught in a prosaic, practical mood, wrote, ‘* And spreading succ’ry chokes the rising field.” 7O From Blue to Purple Iron-weed; Flat Top (Vernonia Noveboracensis) Thistle family. Flower-head—Composite of tubular florets only, intense reddish purple thistle-like heads, borne on short, branched peduncles and forming broad, flat clusters ; bracts of involucre, brown- ish purple, tipped with awl-shaped bristles. Stem; 3 to 9 ft. high, rough or hairy, branched. Leaves: Alternate, narrowly oblong or lanceolate, saw-edged, 3 to 10 in. long, rough. Preferred Habitat—Moist soil, meadows, fields. Flowering Season—luly—September. Distribution—Massachusetts to Georgia, and westward to the Mississippi. Emerson says a weed is a plant whose virtues we have not yet discovered ; but surely it is no small virtue in the iron-weed to brighten the roadsides and low meadows throughout the sum- mer with bright clusters of bloom. When it is on the wane, the asters, for which it is sometimes mistaken, begin to appear, but an instant’s comparison shows the difference between the two flowers. After noting the yellow disk in the centre of an aster, it is not likely the iron-weed’s thistle-like head of ray florets only will ever again be confused with it. Another rank-growing neighbor with which it has been confounded by the novice is the Joe Pye weed, a far paler, pinkish flower, as one who does not meet them both afield may see on comparing the colored plates in this book. To each tiny floret, secreting nectar in its tube, many insects, attracted by the bright color of the iron-weed standing high above surrounding vegetation, come to feast. Long-lipped bees and flies rest awhile for refreshment, but butterflies of many beautiful kinds are by far the mcst abundant visitors. Pollen car- ried out by the long, hairy styles as they extend to maturity must attach itself to their tongues. The tiger swallow-tail butterfly ‘appears to have a special preference for this flower. Common or Scaly Blazing Star; Colic-root; Rattlesnake Master; Button Snakeroot (Lacinaria squarrosa) Thistle family (Liatris squarrosa of Gray) Flower-heads—Composite, about 1 in. long, bright purple or rose purple, of tubular florets only, from an involucre of over- lapping, rigid, pointed bracts ; each of the few flower-heads 71 From Blue to Purple from the leaf axils along a slender stem in a wand-like raceme. Stem: ¥% to 2 ft. high. Leaves: Alternate, narrow, entire. Preferred Habitat—Dry, rich soil. Flowering Season—June—September. oe ee to the Gulf of Mexico, westward to Ne- raska. Beginning at the top, the apparently fringed flower-heads open downward along the wand, whose length depends upon the richness of the soil. All of the flowers are perfect and attract long-tongued bees and flies (especially Exoprosopa fasctata) and butterflies, which, as they sip from the corolla tube, receive the oe carried out and exposed on the long divisions of the style. ome people have pretended to cure rattlesnake bites with appli- cations of the globular tuber of this and the next species. The Large Button Snakeroot, Blue Blazing Star, or Gay Feather (L. scariosa), may attain six feet, but usually not more than half that height; and its round flower-heads normally stand well away from the stout stem on foot-stems of their own. The bristling scales of the involucre, often tinged with purple at the tips, are a conspicuous feature. With much the same range and choice of habitat as the last species, this Blazing Star is a later bloomer, coming into flower in August, and helping the golden-rods and asters brighten the landscape throughout the early autumn. The name of gay feather, miscellaneously applied to several blazing Stars, is especially deserved by this showy beauty of the family. Unlike others of its class, the Dense Button Snakeroot, Devil’s Bit, Rough or Backache Root, Prairie Pine or Throatwort (L. spicata), the commonest species we have, chooses moist soil, even salt marshes near the coast, and low meadows throughout a range nearly corresponding with that ofthe scaly blazing star. Resembling its relatives in general manner of growth, we note that its oblong involucre, rounded at the base, has blunt, not sharply pointed, bracts; that the flower-heads are densely set close to the wand for from four to fifteen inches ; that the five to thirteen bright rose-purple florets which compose each head occasionally come white ; that its leaves are long and very narrow, and that October is not too late to find the plant in bloom. tue and Purple Asters or Starworts Thistle family Evolution teaches us that thistles, daisies, sunflowers, asters, and all the triumphant horde of composites were once very dif- ferent flowers from what we see to-day. Through ages of natural 72 From Blue to Purple selection of the fittest among their ancestral types, having finally arrived at the most successful adaptation of their various parts to their surroundings in the whole floral kingdom, they are now Overrunning the earth. Doubtless the aster’s remote ancestors were simple green leaves around the vital organs, and depended upon the wind, as the grasses do—a most extravagant method— to transfer their pollen. Then some rudimentary flower changed its outer row of stamens into petals, which, gradually took on color to attract insects and insure a more economical method of transfer. Gardeners to-day take advantage of a blossom’s natural tendency to change stamens into petals when they wish to pro- duce double flowers. As flowers and insects developed side by side, and there came to be a better and better understanding be- tween them of each other’s requirements, mutual adaptation fol- lowed. The flower that offered the best advertisement, as the composites do, by its showy rays; that secreted nectar in tubu- lar flowers where no useless insect could pilfer it ; that fastened. its stamens to the inside wall of the tube where they must dust with pollen the under side of every insect, unwittingly cross-fer- tilizing the blossom as he crawled over it; that massed a great number of these tubular florets together where insects might readily discover them and feast with the least possible loss of time—this flower became the winner in life’s race. Small wonder that our June fields are white with daisies and the autumn land- scape is glorified with golden-rod and asters ! Since North America boasts the greater part of the two hundred and fifty asters named by scientists, and as varia~ tions in many of our common species frequently occur, the tyro need expect no easy task in identifying every one he meets afield. However, the following are possible acquaintances to every one: In dry, shady places the Large, or Broad-leaved Aster (A. ma- crophyllus), so called from its three or four conspicuous, heart- shaped leaves on long petioles, in a clump next the ground, may be more easily identified by these than by the pale lavender or violet flower-heads of about sixteen rays each which crown its reddish angular stem in August and September. The disk turns reddish brown. In prairie soil, especially about the edges of woods in western New York, southward and westward to Texas and Minnesota, the beautiful Sky-blue Aster (4. azureus) blooms from August till after frost. Its slender, stiff, rough stem branches above to display the numerous bright blue flowers, whose ten to twenty rays measure only about a quarter of an inch in length. The upper leaves are reduced to small flat bracts ; the next are linear ; and the lower ones, which approach a heart shape, are rough on both sides, and may be five or six inches long. Much more branched and bushy is the Common Blue, Branch- ing, Wood, or Heart-leaved Aster (A. cordifolius), whose generous 73 From Blue to Purple masses of small, pale lavender flower-heads look like a mist hang ing from one to five feet above the earth in and about the woods and shady roadsides from September even to December in favored laces. The Wavy or Various-leaved Aster or Small Fleabane (A. un- dulatus) has a stiff, rough, hairy, widely branching stalk, whose thick, rough lowest leaves are heart-shaped and set on long foot- stems ; above these, the leaves have shorter stems, dilating where they clasp the stalk; the upper leaves, lacking stems, are seated on it, while those of the branches are shaped like tiny awls. The flowers, which measure less than an inch across, often grow along one side of an axis as well as in the usual raceme. Eight to fifteen pale blue to violet rays surround the disks which, yel- low at first, become reddish brown in maturity. We find the plant in dry soil, blooming in September and October. By no means tardy, the Late Purple Aster, so-called, or Purple Daisy (A. patens), begins to display its purplish-blue, daisy-like flower-heads early in August, and farther north may be found in dry, exposed places only until October. Rarely the solitary flow- ers, that are an inch across or more, are a deep, rich violet. The twenty to thirty rays which surround the disk, curling in- ward to dry, expose the vase-shaped, green, shingled cups that terminate each little branch. The thick, somewhat rigid, oblong leaves, tapering at the tip, broaden at the base to clasp the rough,, slender stalk. Range similar to next. «Certainly from Massachusetts, northern New York, and Min- nesota southward to the Gulf of Mexico one may expect to find the New England Aster or Starwort (4. Nove-Anglia), one of the most striking and widely distributed of the tribe, in spite of its localname. . . . «. « « «© | The branching clus- ters of violet or magenta-purple flower-heads, from one to two inches across—composites containing as many as forty to fifty purple ray florets around a multitude of perfect five-lobed, tubu- lar, yellow disk florets in a sticky cup—shine out with royal splendor above the swamps, moist fields, and roadsides from Au- gust to October. Thestout, bristle-hairy stem bears a quantity of alternate lance-shaped leaves lobed at the base where they clasp it. In even wetter ground we find the Red-stalked, Purple- stemmed, or Early Purple Aster, Cocash, Swanweed, or Meadow Scabish (A. puniceus) blooming as early as July or as late as November. _ Its stout, rigid stem, bristling with rigid hairs, may reach a height of eight feet to display the branching clusters of pale violet or lavender flowers. The long, blade-like leaves, usually very rough above and hairy along the midrib beneath, are seated on the stem. The lovely Smooth or Blue Aster (4. /evis), whose sky-blue or violet flower-heads, about one inch broad, are common through September and October in dry soil and open woods, has strongly 74 From Blue to Purple clasping, oblong, tapering leaves, rough margined, but rarely with a saw-tooth, toward the top of the stem, while those low down on it gradually narrow into clasping wings. In dry, sandy soil, mostly near the coast, from Massachusetts to Delaware, grows one of the loveliest of all this beautiful clan, the Low, Showy, or Seaside Purple Aster (A. spectabilis). The stiff, usually unbranched stem does its best in attaining a height of two feet. Above, the leaves are blade-like or narrowly oblong, seated on the stem, whereas the tapering, oval basal leaves are furnished with long footstems, as is customary with most asters. The handsome, bright, violet-purple flower-heads, measuring about an inch and a half across, have from fifteen to thirty rays, or only about half as many as the familiar New England aster. Season : August to November. The low-growing Bog Aster (A. nemoralis), not to be con- fused with the much taller Red-stalked species often found growing in the same swamp, and having, like it, flower-heads measuring about an inch anda half across, has rays that vary from light vio- let purple to rose pink. Its oblong to lance-shaped leaves, only two inches long at best, taper toa point at both ends, and are seated on the stem. We look for this aster in sandy bogs from New ae northward and westward during August and September. he Stiff or Savory-leaved Aster, Sandpaper, or Pine Starwort (lonactis linariifolius), now separated from the other asters into a genus by itself, is a low, branching little plant with no basal leaves, but some that are very narrow and blade-like, rigid, entire and one-nerved, ascending the stiff stems. The leaves along the branches are minute and awl-shaped, like those on a branch of pine. Only from ten to fifteen violet ray flowers (pistillate) surround the perfect disk florets. From Quebec to the Gulf of Mexico, and westward beyond the Mississippi this prim little shrub grows in tufts on dry or rocky soil, and blooms from July to October. Robin’s, or Poor Robin’s, or Robert’s Plan- tain; Blue Spring Daisy; Daisy-leaved Fleabane (Erigeron pulchellus) Thistle family (E. bellifolium of Gray) Flower-heads—Composite, daisy-like, 1 to 174 in. across ; the outer circle of about 50 pale bluish-violet ray florets; the disk florets greenish yellow. Stem: Simple, erect, hairy, juicy, flexible, from 10 in. to 2 ft. high, producing runners and offsets from base. Leaves: Spatulate, in a flat tuft about the root; stem leaves narrow, more acute, seated, or partly clasping. 75 From Blue to Purple Preferred Habitat—Moist ground, hills, banks, grassy fields. Flowering Season—April—June. Distribution—United States and Canada, east of the Mississippi. Like an aster blooming long before its season, Robin’s plantain wears a finely cut lavender fringe around a yellow disk of minute florets ; but one of the first, not the last, in the long procession of composites has appeared when we see gay companies of these flowers nodding their heads above the grass in the spring breezes as if they were village gossips. Doubtless it was the necessity for attracting insects which led the Robin’s plantain and other composites to group a quantity of minute florets, each one of which was once an independent, detached blossom, into a common head. In union there is strength. Each floret still contains, however, its own tiny drop of nectar, its own stamens, its own pistil connected with em- bryonic seed below ; therefore, when an insect alights where he can get the greatest amount of nectar for the least effort, and turns round and round to exhaust each nectary, he is sure to dust the pistils with pollen, and so fertilize an entire flower-head in a trice. The lavender fringe and the hairy involucre and stem serve the end of discouraging crawling insects, which cannot transfer pollen from plant to plant, from pilfering sweets that cannot be properly paid for. Small wonder that, although the composites have attained to their socialistic practices at a comparatively recent day as evolutionists count time, they have become as individuals and us species the most numerous in the world ; the thistle family, dominant everywhere, containing not less than ten thousand members. : Common or Philadelphia Fleabane, or Skevish (E. Philadel- phicus), a smaller edition of Robin’s plantain, with a more finely cut fringe, its reddish-purple ray florets often numbering one hun- dred and fifty, may be found in low fields and woods throughout North America, except in the circumpolar regions. Thistles (Carduus) Thistle family Is land fulfilling the primal curse because it brings forth thistles? So thinks the farmer, no doubt, but not the goldfinches which daintily feed among the fluffy seeds, nor the bees, nor the ‘‘painted lady,” which may be seen in all parts of the world where thistles grow, hovering about the beautiful rose-purple flowers. In the prickly cradle of leaves, the caterpillar of this thistle butterfly weaves a web around its main food store. 76 From Blue to Purple When the Danes invaded Scotland, they stole a silent night march upon the Scottish camp by marching barefoot; but a Dane inadvertently stepped on a thistle, and his sudden, sharp cry, arousing the sleeping Scots, saved them and their country: hence the Scotch emblem. From July to November blooms the Common, Burr, Spear, Plume, Bank, Horse, Bull, Blue, Button, Bell, or Roadside Thistle (C. lanceolatus or Circitum lanceolatum of Gray), a native of Europe and Asia, now a most thoroughly naturalized American from New- foundland to Georgia, westward to Nebraska. Its violet flower- heads, about an inch and a half across, and as high as wide, are mostly solitary at the ends of formidable branches, up which few crawling creatures venture. But in the deep tube of each floret there is nectar secreted for the flying visitor who can properly transfer pollen from flower to flower. Such a one suffers no in- convenience from the prickles, but, on the contrary, finds a larger feast saved for him because of them. Dense, matted, wool-like hairs, that cover the bristling stems of most thistles, make climbing mighty unpleasant for ants, which ever delight in pilfering sweets. Perhaps one has the temerity to start upward. ‘* Fain would I climb, yet fear I to fall.” “If thy heart fail thee, climb not at all,” might be the ant’s passionate outburst to the thistle, and the thistle’s reply, instead of a Sir Walter and Queen Elizabeth coup- let. Long, lance-shaped, deeply cleft, sharply pointed, and prickly dark green leaves make the ascent almost unendurable; never- theless the ant bravely mounts to where the bristle-pointed, over- lapping scales of the deep green cup hold the luscious flowers. Now his feet becoming entangled in the cottony fibres wound about the scaly armor, and a bristling bodyguard thrusting spears at him in his struggles to escape, death happily releases him. All this tragedy to insure the thistle’s cross-fertilized seed that, seated on the autumn winds, shall be blown far and wide in quest of happy conditions for the offspring! ; Sometities the Pasture or Fragrant Thistle (C. odoratus or C. pumilum of Gray) still further protects its beautiful, odorous purple or whitish flower-head, that often measures three inches across, with a formidable array of prickly small leaves just below it. In case a would-be pilferer breaks through these lines, however, there is aslight glutinous strip on the outside of the bracts that compose the cup wherein the nectar-filled florets are packed ; and here, in sight of Mecca, he meets his death, just as a bird is caught on limed twigs. The pasture thistle, whose range is only from Maine to Del- aware, blooms from July to September. Even gentle Professor Gray hurls anathema at the Canada Thistle; ‘‘a vile pest” he calls it. As Cursed, Corn, Hard, and 77 From Blue to Purple Creeping Thistle it is variously known here and in Europe, whence it came to overrun our land from Newfoundland to Virginia, west- ward to Nebraska. By horizontal rootstocks it creeps and forms patches almost impossible to eradicate. The small reddish-pur- ple flower-heads, barely an inch across, usually contain about a hundred florets each. In their tubes the abundant nectar rises high, so that numerous insects, even with the shortest tongues, are able to enjoy it. Not only bees and butterflies, but wasps, flies, and beetles feast diligently. When a floret opens, a quantity of pollen emerges at the upper end of the anther cylinder, pressed up by the growing style. Owing to their slight stickiness and the sharp processes over their entire surface, the pollen grains, which readily cling to the hairs of insects, are transported to the two- branched, hairy stigma of an older floret. But even should insects not visit the flower (and in fine weather they swarm about it), it is marvellously adapted to fertilize itself. Farmers may well despair of exterminating a plant so perfectly equipped in every part to win life’s battles. “ The colour of purple . . . was, amongst the ancients, typical of royalty. Itwas a kind of red richly shot with blue, and the dye pro- ducing it was attained from a shell found in considerable numbers off the coast of Tyre, and on the shore near the site of that ancient city, great heaps of such shells are still to be found. The production of the true royal purple dye was a very costly affair, and therefore it was often imi= tated with a mixture of cochinealandindigo. . . .—J. JAMES TISSOT.

To measure petals, to count stamens, to describe pistils without reference to their functions, or the why and wherefore of their existence, is to content one’s self with husks in the presence of a feast of fatness—to listen to the rattle of dry bones rather than the heavenly harmonies of life. We have reason to be profoundly thankful for the signs to be seen on every side, that the dreary stuff which was called botany in the teaching of the past will soon cease to masquers ade in its stolen costume, and that our children and our children’s children will study not dried specimens or drier books, but the living things which Nature furnishes in such profusion. “ The reason of this radical change is not far to seek. Since man has learned that the universal brotherhood of life includes himself as the highest link in the chain of organic creation, his interest in all things that live and move and have a being has greatly increased. The move- ments of the monad now appeal to him in a way that was impossible under the old conceptions. He sees in each of the millions of living forms with which the earth ts teeming, the action of many of the laws which are operating in himself; and has learned that to a great extent his welfare
