The love of flowers is one of the earliest of passions, as it is one of the most enduring. Children with the bees and butter- Ihes delight in the opening of the spring ; and a bright boy that IS reared in the country follows the season by its flowers He It IS that knows when to push aside the snow and dried leaves to find the hrst sweet blossoms of the trailing arbutus • nor does he mistake the dell where the white violet peeps shyly out for the spreading patch of blue violets to which he return^- every year. He knows the hillside where the mountain laurel and the lambkill grow, and drives away the foolish cows that would eat of their fresh, green shoots. The precious haunt of the pink orchis and the rocky crag over which droops the lovely columbine is to him an unravelled mystery. A stream of fish- nig he marks by the stately cardinal flower or the coy jewel- weed. His knowledge of them all is intimate and loving-one that he has acquired by his own skill and observation, and through this close friendship with them he feels proudly that they are his very own. The swamps and the woods, the hills and the road- sides, are his ospecial domain. The great poets of America have shown a profound apprecia- tion of their incomparable wild flowers. In fact, the impersonal love of flowers is one of the characteristics of modern poetrv Hut this has not always been so. The Persians made use of their flowers as mouthpieces to express their own sentiments and from them the idea radiated very generally. They served the ancient Greeks mostly as tombstones to commemorate their sorrows : and although the Greek boy knew where to And them and honoured them as favourites of his gods, he had not the 7 VI PREFACE. same sentimental fondness for them as has our little American friend. A .vi Id rose would never say to him : " 1 despise you ; " nor does he expect a black-eyed Susan to blush from shyness. The wild flowers have their own unique personalities. They exist as individuals and reproduce themselves. Every plant is a member of a family and has its relatives quite as well as tliose of the animal world. To know them it is necessary that we should seek them in their homes : they seldom come to us. It is for this reason that a classification according to the soil in which they grow is feasible. It is a tangible point of which to take hold. And although there are some fickle-minded plants that appear to flourish in different kinds of soil, they may be regarded rather as those straying away from family tradition, than as trustwort .y examples. As a rule they are partial to particular kinds of soil and do not thrive nearly so well in other than that allotted to ihem by Dame Nature. The marsh marigold, with which most of us are familiar, when it reaches the sunny, warmer south retires to the wet, cool woods in search of a soil similar to that of its home marshes. The harebell, that is with us a shy plant, hiding itself in shady places and rooting in moist soil, in England ventures out into the meadows and highways. It lias there not our midsummer heat vi'th which to contend and finds the soil of the fields not unlike that of our shaded banks. It would therefore seem that, putting aside an analysis of th^-'r minuter parts, ihe different species of plants could hv most readily known by their locality. With one exception the great family of golden-rods are yellow ; but they do not all grow in the saiue kind of soil. The knowledge, therefore, that one inhabits a swamp will be of more value to identify it than to know its colour. For the convenience of those, however, that are accustomed to a classification by colour, an index, in which the plants are arranged under the dominant colour of the blossoms, has been provided. With the knowledge of this point and knowing also the soil PREFACE. VII ex, in e soil ill which they grow, little difficulty should be encountered in determining the position of any plant in the book. It has seemed most natural to make the divisions of soil according to a gradatioi' from plants that grow in water through those of mud and those of moist, lich, rocky, light and sandy soils respectively to those that flourish in dry and waste gromid. Under this classification the primary idea in group- ing the genera has been to keep the families together, and so far as is consistent with this plan they have been arranged according to their seasons of blooming. The common English name, or several common names, when they exist, and the scientific names of the plants are first given. Accents have been placed upon tlie latter as being an assistance to their correct pronunciation. Then follow, so that they may be seen at a glance the family, colour, odour, range and time of bloom. A simple analysis is also given, from which the manner of their growth and the form and number of their parts can be learned. From the routine order of placing first the root, or stem, a deviation has been indulged in by beginning with a description of the flowers. It is thought to be more considerate to allow the novice to satisfy his enthusiasm over the blossom before claiming his attention for the root, stem, and leaves. The technical terms that have been used will not be found difficult to conquer by a little patience . nd study of the next chapter. The student will then be armed with a vocabulary from which two words will serve him for twenty of his own that he might otherwise employ. Every science has its phe- nomena that individuals are ready to master ; but for some strange reason botany has, until recently, been so enwrapped in the gloom of technical expressions that it has been declared impossible. Happily this idea has become a phantom of his- tory. The change undoubtedly is greatly owing to the many delightful books that have been written on this subject. It is these books that make naturalists. • •• Vlll PREFACE. Modesty, we learn from the flowers, is one of the winsome virtues. It is therefore said with much modesty that what has been formerly lacking to make these books thoroughly useful and practicable to the student is supplied in the present volume. It is COLOUR. To the development of science we owe the existence of the sixty-four coloured plates that are here repro- duced. They and the pen-and-ink sketches are from original studies from nature and show us many of our familiar as well as rare wild flowers. In the selection of them the range has not been limited ; simply from America's great wealth of bloom those have been chosen that have some especial claim on our attention. This work has been greatly facilitated by the most kind and generous aid of Dr. Britton. Mrs. Rowan received invaluable assistance from Mr. Beadle, the well-known botanist of Baltimore ; and while in Asheville was enabled, through his courtesy and that of his colleagues, to get many rare specimens of native plants from the mountains of North Carolina. Besides accuracy, Mrs. Rowan has a particularly happy faculty of transmitting to paper the atmosphere of the plants, so that in looking at them we almost feel their texture and sense a whiff of the salt marsh in which they grew, or the cool, spicy odour of the pine thickets. How differently these coloured plates impress us from those that gave dreary pleasure to our ancestors, when a patch of colour and a bit of green that was taken on faith as the accompanying leaves caused them to exclaim mechanically, " It is a flower." That the book introduces many new friends among the wild flowers and that it adds colour constitutes its claim upon the reader. About the flowers grave lessons cling, Let us softly steal like the tread of spring And learn of them. List of Illustrations.

One of the first questions a botanist asks about a plant is, Where chd it grow," and the next is, -When and where did >ou get It." Yet it is surprising how seldom these points are noted and how many collections are preserved without suffi- c.ent data to guide us in the identification of the specimens I this book does nothing more than emphasize the importance of observing these points it will do good. It will also aid in the appreciation of that new development of botanical study, the science of Plant Ecology. It will teach the novice how altitude, latitude, soil and environment affect the vegetation of certain areas ; how certain plants are found growing together because of the nature of the soil and of their surroundings. If it also leads to the understanding of their gradual adaptation to changed conditions it will give "a broader and more comprehensive view of plant morphology and lead away from the mistaken idea that plants must and^hould con- form to our artificial definitions, and make clearer the laws of evolution. To feel that plants are living things, that individuality and heredity are constantly struggling in them for ascendancv bnngmg about modifications which in course of time are suffi- cient in amount and importance to create specific differences these are the underlying principles of the study of plants 1 hat the love of Nature is gaining ground among us is shown m many ways. The number of books and magazines dealing v.th natural-history subjects in a popular wav, increases yearly to meet an increasing need. A constant demand exists which XVI INTRODUCTION. calls upon our specialists in Science to tell what they know in plain readable language, and expects them to illustrate their meaning in the best and most modern manner. The public calls for increased facilities for learning. Popular lectures, beautifully illustrated, have become the order of the day, and the labour of the brain may be had cheaper than the labour of the hands. Hiology and Nature Study have taken their places in the courses of instruction both in private and public schools and the teachers are struggling to fit themselves to meet the new requirements ; in fact, the supply does not equal the de- mand, j'arents are seeking for companions for their children in their hours of recreation and vacation who can answer (lues- tions on natural objects and phenomena ; if they cannot find the right person, they want correct books and magazines. That the true love of Nature imjioses certain mcjral responsi- bilities is also beginning to be recognised. First and foremost a respect and care for living things will do away with that spirit of wanton destruction which permits the killing of any animal or the uprooting or trampling of a living plant, just for the fun of it. It will also promote a spirit of unselfishness which can enjoy the beauties of Nature and leave them as we found them for some one else to enjoy after us. It also pro- motes an appreciation and love of truth which fosters exactness and precision. From a pedagogic standpoint nature studi-'s are of the utmost importance, as they bring the mind to the consideration of the objective rather than the subjective meth- ods. That they call for greater individuality and latitude of presentation is one of the reasons why it has been diflftcult to secure the right methods. Our schools cannot be bound by hard and fast rules and requirements ; the teacher must meet the needs and opjiortun-'les of the students and these are very diverse in different schools and places. She must be ready to make use of any facilities and accoinplishments that individual scholars may afford for the benefit of the others, and to bring drawing, photography and poetry, as well as prose, to her as- iy know in trate their 'he public ■ lectures, e day, and labour of leir places ic schools meet the il the de- ■ children wer ques- mnot find lies. INTRODUCTION. XVII s.stance. Summer schools and vacation classes seem to meet a widespread want, and to take teachers and pupils away from the densely populated cities is better than to bring livinir plants and animals to them. Therefore a book that leads searchers to ..now what they will find in the country is the best kind of a l)oc)k. Our thanks are due to Miss Lounsberry and Mrs. Rowan for having contributed a work which cannot fail to advance Nature Study in quite the way that it shc.uld be advanced. Mrs Row- an s figures have been drawn from plants growing in their nat- ural surroundings and they are accurate and elegant The new process by which it has been made possible to repi-oduce e oloured paintings is a most valuable addition to methods of illustration. New York Botanical Garden, February 20, 1899. N. L. Britton. A Chapter to Study. No attempt has been made in the following chapter to ac- (|uaint the student with every term that it is possible to use in describing the organs of a phiiil ; but enough have been ex- plained and used throughout the book to give a comprehensive vocabulary i)f the subject and to lead one up to the enjoyment of an altogether scientific work on botany. The existence of the plant and that of the animal are so closely linked together that it would be ratiier difficult to i)ro- phesy the fate of one were the other to withdraw itself from the earth. It is a pleasure to see that they seldom encroach upon each other's mission in life ; but are generously helpful by the most amicable arrangements. The plants absorb from the atmosphere carbonic-acid gas, which, unless this were so, would become abuncUmt in the air and be injurious to animal life. They exhale oxygen, which is the animal's necessary food. The opposite course is pursued by animals. 'I'hey inhale oxygen and exhale carbonic-acid gas. In this way they return the plants' compliment : by taking from them what they do not want and giving them as food what they do want. Again, plants are almost altogether dependent upon animal life to perform for them the service of cross-fertilization, page 7. The birds, the butterflies and Master Hee and his family are all ceaselessly busy as their messengers. But there is nothing mean about the flowers. In return, they are quite aware of, and cater to, the tastes of all. ^Vhen a bird carries the seeds of a flower to some distant place and deposits them, it is only a slight remuneration for the delicious luncheon of red A CHAPTER TO STUDY. berries that he has enjvoyed. If Master Bee follows the road that is plainly marked out for him by a deep, rich veiningand sips to satiety of a gland of nectar ; it is but fair that the anthers should load him well with a cargo of pollen to carry off to the pistil of anoiher flower. In fact, as we become more friendly with the flowers we will cease to look upon them so much as luxurious creatures but rather as those that have solved the deep problems of domestic economy. The plant's individual mission in life is the reproduction of itself. The flower and its products, the fruit and the seeds, are the org?ns of reproduction. The root, the stem and the leaves are the organs of vegeta- tion. The Inflorescence is the manner in which the flowers are arranged upon the stem. When but one flower grows upon the end of the stem or flower-stalk, it is said to be terminal, solitary. It is Axillary when the flower, or flowers, grow from, the axils of the leaves, or in the angle formed by the leaf, or leaf- stalk, and t'le stem. (Fig. i.) %^i^ '^ FIG. I. FIG. 2. FIG. 3.

An Umbel is like a corymb, only the pedicels branch from the same central point, suggesting the ribs of an umbrella. It may be sini|)le, or compound. (Fh;. 9.) A Cyme is a flat-topped inflorescence, differing from an umbel in tliat its innermost flowers are the first to open. (Fig. 10.) A Complete flower is one that is provided with the essential organs of reproduction, the stamkns and pistil ; and the pro- tecting organs, the calyx and corolla. As an example of a complete or typical flower we may take the one illustrated in Fig. II and 12. Co/foii* Kin. II. FIG. 12. FIG. 13. The Calyx is the lower, outer set of leaves at the base of the flower that rests upon the receptacle, or end of the flower- stalk. It is usually green, but not always. At times we find it brilliantly coloured and conspicuous. (See Fig. 12.) The Sepals are the leaves of tlie calyx when it is ilivided to the base. The Calyx is gamoslpalijus when the sepals are wholly or partly grown together. The Corolla is the next inner and upper set of leaves. It is the alluring part of the flower, and attracts the bees and but- terflies to its whereabouts that its pollen maybe carried through their agency. (Fig. 12.) The Petals arc the leaves of the corolla when it is divided to the base. The Corolla is said to be gamopetalous when the petals are wlu)lly or partly grown together. ranch from iibrella.

When they are divided about one-half they are said to be cleft, or lobed. They are TOOTHED when the lobes are very small. When the parts of the Calyx or Corolla are united, the terms used to express their dilferent forms are: Salver-Shaped : when the border is flat and spread out at right angles from the top of the tube.

Labiate : when there is an apparently two-lipped division of the parts. In this form of corolla usually two petals grow to- gether and make the upper lip ; the remaining three petals join together and form the lower lip. These divisions appear mostly as lobes, and it is not always noticed that the flowers are of five lobes instead of two. (Fig. ig.) Bmnch V/irtes FIG. 22. FIG. 23. ANTiter .S'TliKA Stylc OVAMY Oruus FIG. 24. FIG. 25. When the petals are not grown together but are wholly sepa- rate, the corolla is said to be polypetalous. Different forms are : Rosaceous : when the petals arc distinct and without claws, as in the rose. Cruciferous ; when there are four clawed petals in the form of a cross. (Fk;. 20.) Papilionaceous, or butterfly-shaped. (Fig. 21.) Such flowers are usually described in three parts : the banner, or standard, which is the large upper petal ; the wings, or the two side petals, and the two anterior petals that, commonly united in a shape something like the prow of a boat and enclos- ing the reproducing organs, are called the keel.

Irregu- lar Flowers are the reverse of regular. (Fig. 24.) It is sometimes found that only t)nc set of floral leaves is present. It is then regarded as the Calyx. Collectively the floral envelope, or the protecting organs, is spoken of as the Perianth ; but the word is mostly used in cases where the calyx and corolla run into each other so that it is difficult to distinguish them apart. The lily family have a perianth. The Stamens, or Fertilizing Organs, of the plant are composed of two parts : the Filament, or stalk, which is use- ful to uphold the Anther ; and the Anther, a tiny two-celled box which contains the Pollen. 'I'lu' Pollen is the yellow fertilizing powder which is the essential product of the stamens. (Fig. 25.) Exserted Stamens are those that protrude from the corolla. Included Stamens are those that are within the corolla. The Pistil, or Seed-Bearing Organ, s divided into three parts: the Ovary, the Style, and the Stigma. (Fig. 26.) The Ovary is the lower expanded part of the pistil that contains the Ovules, or undeveloped seeds. (I'ig. 26.) The Style is the slender stalk that usually surmounts the ovary. (Fu;. 26.) The Stigma is the flat or variously formed body that ter- minates the style. (Fu;. 26.) Unlike the otlur organs of the plant, it is not covered by a thin skin or epidermis. Its surface is therefore moist and rough so that it readily receives and holds the pollen when it is deposited upon its surface. Each tiny pollen grain that alights on tlie stigma sends out a minute tube that pierces down through the style until it reaches an ovule below, which it quickens into life. This is known as the process of Fertilization. The ovules then de- velop into Seeds, and the ovary enlarges into the Fruit, or Seed Vessel. Cross-Fertilization is when the pollen of one flower is 8 A CHAPTER TO STUDY. carried to the stigma of another by some extraneous agency, such as the wind or animal life. Self-Fertilization is when the stigma receives the pollen from the stamens in the same flower-cup as itself. To prevent this catastrophe the plants are ever upon the alert, experience teaching them that the result is not got)d. Often either no seeds at all mature or their progeny is a weakling. FIG. 30.

Pistillate Flowers are those that have pistils but no stamens. The terms male and fkmalk that are sometimes employed in- stead of staminatf: and tistillatp: are used wrongly and should be avoided by even those that have no pretention to botanical knowledge. It is the product of these organs and not they themselves that should be so called if the terms are used at all ; but staminate and pistillate are the correct and accepted expressions. ('leistogamous flowers are those small, inconspicuous blos- soms of the late season that usually grow near the ground and never open. They are, however, fruitful, being self-fertilized within themselves, Violets bear them abundantly. Leaves may be looked upon as appendages of the stem. They are the digestive organs of the plant and assimilate the sap into material for sustaining its tissues. The Blade is the usually broad, flat part of the leaf. Stipules are the two small blade-like parts at the base of the petiole. They are often inconspicuous, or absent. Bracts are the modified leaves of an inflorescence or those that are under a flower. Usually they are green and of different size and shape than the rest of the foliage ; sometimes, how- ever, they are highly coloured and petal-like. The three principal ways in which leaves are arranged upon the stem are : Alternate : that is when one leaf appears just above the other on another side of the stem, (Fig. 27.) Opposite : when two appear at each joint, having the semi- circle of the stem between them. (Fio. 28.) Whorled : when they grow at intervals in a circle around the stem. (Fio. 29.) The Veining of the leaves is classed under two divisions : Netted- Veined and Parallel- Veined. Netted-Veined leaves are tliose in which the veins branch 10 A CHAP IKK. lU STUDY. off from the midrib and branch again into veiiilets that run to- gether and form a network, or mesh. (1*"ig. 30,) Netted- veined leaves are said to be Feather-Veined w hen the sec- ondary veins all start from the sides of the midrib, running from the base to the apex of the leaf. (Fid. 31.) They are called Palmately-Veined when several veins of equal size start from the same point at the base of the leaf and spread out towards the margin. Parallel-Veined leaves are those in which the main veins run side by side, without branching or running together. (Fio. 32.) The veining of the leaves is always in complete harmony with their shape, so that much can be learned by noticing this featun' carefully. FIG. 33. FIG. 34. FtG. 35. FIG. 36. Leaves vary greatly in general outline, and the following terms are used to designate some of their common forms : Linear: the narrowest form of a leaf — several times longer than broad : grass-like. (Fic. 32.) Lanceolate : long and narrow, slightly broader at the base and tapering towards the apex. (Fig. 30.) Oblanceolate is a reversed lanceolate. Oblong; when two or three times broader than long. (Fig. 31.) Elliptical : oblong but tapering at both ends. (Fig. ^^.) Oval : broadly elliptical. (Fig. 34.)

The Tuber is tlu: end of a rootstock that is thickened or enlarged. The enlarged part is possessed of eyes (buds). The common potato is a familiar illustration of tubers. (Fk;. 52.) The Corm is a rounded, compact rootstock. (Kio. 53.) The Bulb is a corm mostly made up of fleshy scales. (Tig. 54.) FIG. 52. FIG. 53. FIG, 54. The Scape is a Icallcss peduncle, or the llower-stalk of a plant that has no stem. The Root proper grows downward in the ground and bears nothing but rootlets and root-branches. Its principal function in life is to absorb the nourishment from the soil. Aerial Roots are produced in the ojien air and serve the plant by acting as holdfasts, or heljiing it lo climb. Parasites intermingle their roots with the roots or stems of other plants and drain from them their sustenance. Thorns are modified branches. Their purpose is to guard the plant from animals that would strip it of its stem and bark. 4 Five Conspicuous Plant Families. [•-stalk (»r a We find, much to our encouragement, that there are a few plant families with which we at once become familiar ; and their marked features impress us as those of unusual faces that have to be seen but once to be clearly remembered. 'The greater number of families, however, and their branches are not so read- ily known. The least little variation in a i)Iant's manner of growth will cause it to be separated from its relatives, even if it has to be regard, i as a new species. The first Latin or oek word of a plant's scientific name is the name of its genus: its family name. The second word is an adjective that denotes its species and is usually significant of some characteristic or history with which it is connected. These names are too valuable to be overlooked, and as much as possible they should be memorised. The world over, a plant's scientific name is the same, while the common English names often change not only with country, but with state and town. Following are a few traits of families that are among those most easily recognised : or stems of THE ARUM FAMILY. Although one of the smallest in numbers, the arum family comprises some of our most quaint and interesting flowers. Its characteristics are strongly marked and its tastes appear to be most patrician. We may believe that it does not concern it- self about the fashions, as it makes no attempt to follow the i6 FIVE CONSPICUOUS PLANT FAMILIES. ■St. modes of other noted families ; but continues its own conserva- tive way of bearing its flowers closely packed on a thick spadix and usually sheathing them with a handsome spathe. These tiny flowers are often imperfect and sometimes naked, — that is, without ^alyx or corolla. Wiien the latter are present they are seldom highly coloured. Under the microscope they are excellent studies and sometimes very beautiful. As a family they show a keen appreciation of harmony in the exquisite blending of colours in the spathe, or by its appearing spotlessly white. The white calla, the stately queen of the greenhouses, Jack in the pulpit and the skunk cabbage are all conspicuous members. The golden club is the wayward exception, in having no spathe. All are widely dissimilar in appearance and hold different posi- tions in life, and yet they ' -'ar so strongl\ the marks of this exclusive family as to be at once recognisable. The leaves are mostly rather netted-veined and the plants contain an acrid, pungent, watery juice. Many of them are also known as yield- ing an edible farina, or starch. THE LILY FAMILY. The lily family is one that is distmctly marked by its regular, symmetrical flowers. Its floral envelope is a perianth that is sometimes white or gaily coloured, but very rarely green. Al- most invariably it is of six equal [iarts. There are six stamens with two-celled anthers, and a three-celled ovary that is free from the receptacle. The style is undivided. The leaves are entire and ixirallel-veined, or sometimes netted-veined. The word lily would probably form as many different pic- tures in the mind as there were individuals to whom it had been presented. Some would at once recall the greenhouse calla. which, as has already been said, is no lily ; all and a member of the arum family. Others would think of the pure resurrec- tion lily and again others would think of the swarthy, upright ES. n conserva- Iiick spadix lines naked, are present oscope they mony in the s appearing- ises, Jack in IS members, fj no spathc. iTerent posi- arks of this e leaves are iin an acrid, \vn as yield- 'M FIVE CONSPICUOUS PLANT FAMILIES. 17 its reguhir, anth that is |
