Tue present Work forms one of a projected series of Ilustrated Volumes on British Natural History. It has not been pre- pared in consequence either of a lack of books on the same subject or of any deficiency in those which are accessible, but simply to bear its part towards the completion of a naturalist’s library upon a plan as nearly as practicable uniform with Mr. Berkeley’s ‘ Fungology,’ with which the series commenced. The book thus originated has been written with the aim of making it effective in training up students for the more advanced and technical Floras of Babington, Bentham, and Hooker. For this purpose, dissections of the parts of the flowers have been introduced among the figures; and the illustrated plants, which furnish a tolerably complete series as regards important features of structure, have for the same reason been rather fully described. By these means it is hoped that an insight into the structure and classification of plants will be acquired by those who may honour the book by making it their ‘Companion ;’ and this insight, if attained, v1 PREFACE. will assuredly enable them to use profitably the more tech- nical volumes to which allusion has been made. That of Mr. Bentham has been herein most generally followed. “Though it has been sought to use as few technical terms as possible, they have not been entirely avoided : that indeed being all but impracticable, without largely increasing its bulk, in a book devoted to matters of science, even when presented in a popu- larized form. Where, however, such terms have been used, the attempt has been made to soften them down and make them self-explanatory as much as possible. Beyond this, a Glossary has been provided to elucidate the rest. We may here briefly point out how the book is intended to be used. First it will be evident, on scanning a few of its pages, pp. 22 to 42 for example, that the bouquet form of gathering wild flowers, in which, judging from one’s correspondence, lady-botanists are most apt to indulge, is not the proper bo- tanical form; that is to say, little sprigs of flowers, consisting mainly of flowers, and without leaves and fruits, are not the materials from which a proper knowledge of the plants or of their classification is to be learned. It will be seen on glancing over these pages, that not only are flowers with their stamens and their pistils required for examination, but there are carpels with their seeds to be sometimes looked into, and there are leaves with their ribs and veins to be closely scruti- nized—these latter, indeed, being almost the first which the uninitiated botanist must inquire about. It is clear, therefore, PREFACE. Vil that complete examples should be gathered, completeness be- ing determined thus: all small plants should be entire, root and branch; while of larger ones portions as ample as may be manageable (if for an herbarium, nearly as long as the paper used, or such as can while fresh be readily folded to the length of the paper) must be selected, showing all the parts,—roots if conveniently obtainable; perfect leaves, both root-leaves and stem-leaves, if they differ at all, as they often do; and flowers including buds and old flowers with advanced fruits. Sometimes perfect full-grown fruits or seed-vessels are indis- pensable, and, as they are always desirable, they should always if possible be gathered. Furnished with such materials as these, and supposing ourselves occupied with them at any pe- riod of the pleasant springtide, let us look at p. 22 and p. 27, wherein the two great divisions of plants are indicated. These, it will be seen, consist of plants with parallel-veined leaves and those with net-veined leaves. It is not generally difficult to decide between these, for we may leave out of sight the very few exceptions to the general rule that occur. Supposing our plant is a Wallflower, it will be net-veined, and therefore exo- genous. Now among the exogenous plants it will be seen that there are some polypetalous (the Thalamiflores and Caly- ciflores), some monopetalous (the Monopetals), and some apetalous or without petals (the Monochlamyds). It will ata glance be ascertained that this flower has petals as well as calyx, and more than one petal, so that it must be polypeta- Vill PREFACE. lous. Well then, to which of the polypetalous groups does it belong—that with petals distinct and stamens hypogynous, or that with petals distinct and stamens perigynous or epigynous? It proves, when pulled to pieces, first gently tearing away the calyx and then the petals, to have hypogynous stamens: so that it is one of the Thalamiflores. Then comes the question, are the carpels distinct or combined into an apocarpous ovary? They are combined. After that the question, whether the placentas are parietal or axile? They are parietal. Still again another inquiry, whether the stamens are five or six in num- ber? They are six, and tetradynamous. -We should thus ar- rive at the fact that it belonged to group 3, or the Cruciferous plants. Then turning to group 3 in p. 28, two decisions would lead us to fix on the eighth genus, Cheiranthus. Passing on to the eighth genus in p. 44, it would at last be found that the plant was Cheiranthus Cheiri. By a similar use of the tabulated information the names of the other plants would be ascertained. The book does not contain all our British plants, but only those which have been deemed the most likely to be met with either in home-walks or during more extended health-seeking or pleasure-seeking trips. These have been divided under the four seasons, an arrangement which it has been thought would simplify the task of searching for the name of a flower by excluding those which bloom during other seasons, Gene- rally this would be the case, but instances may here and there PREFACE. ix oceur in which the flowering season does not very definitely fall within these limits; and there are some plants which bloom continuously or successionally. If a plant, therefore, should not be readily identified amongst those set down for the season in which it may be found in bloom, those of the preceding or succeeding seasons should also be scrutinized. It is perhaps hardly necessary to add, that in using the Summaries, care should be taken to compare correctly with their correlatives the various terms and signs employed for subdividing the groups. Thus in p. 22, Exogenous plants are to be compared only with Endogenous plants (the words will be found printed in the same type) in p. 27; Thalami- flores, Calyciflores, Monopetals, and Monochlamyds, (also printed in correspondent type,) must be compared with each other; and the * in p. 23 compared with ** in p. 24: the signs which fall between * and ** in like manner being compared among themselves. The different signs are used for the purpose of classification in the consecutive order which is usual in printed books, namely, *, t, f, §, ||, a, 1, ete. We should strongly recommend those who may take this book as a guide in acquiring a knowledge of our Wild Flowers, to gather as many of those which are figured as they may be able to collect, and to compare them closely both with the figures and with the lengthened descriptions, which latter will be found under the head “ Illustrations,” at pp. 1, 78, 348, and 386. They should especially separate the parts of the a x PREFACE, flowers, so as to get a clear conception of the terms by which the several parts are known, as well as those by which their characteristic features, taken either separately or collectively, are indicated. It may be well further to.point out, that it would be by no means labour lost to commit to memory the more important of the technical terms found in the Glossary. The advantage of knowing their meaning would at once be discovered on making real use of the book. CHELSEA, May, 1862. CONTENTS. --+#— Page SPRING FLOWERS. ILLUSTRATIONS. . ; ‘ : ; ce oe SUMMARY. I.

ES Re. * Bring flowers. They speak of hope to the fainting heart, With a voice of promise they come and part ; They sleep in dust through the winter hours, They break forth in glory ; bring flowers, bright flowers.” Mrs. Hemans. ILLUSTRATIONS. Esprctatty deserving of precedence amongst Spring Flowers is the Primrose,* first or primal flower of the year, which at any time after the winter solstice may be seen peeping forth from many a sheltered bank, on the look-out, as it were, for sunnier days, or else may be found snugly nestling in some sheltered copse or hedgerow, blossoming unheeded, the herald of approaching spring. Even in more rigorous seasons, when the wintry blasts are severe and prolonged, this earliest flower is found soon arousing from its winter sleep. Seldom indeed does the first month of the year pass away without the echo- ing cry through the dreary town, “ Primroses, all a-growin’, all a-blowin’: buy my pretty primroses.” And though it is only when spring has come at last, and in good earnest, * Primula vulgaris—Plate 4 B. 2 SPRING FLOWERS. that the thick tufts of modest blossoms show “the rathe primrose ” in its fullest beauty, we do well to be thankful for the earnest which it gives us of the Flora of the new-born year. This well-known favourite flower, besides illustrating the Primulaceous family, will afford us a general botanical lesson, ere we pass on to notice other heralds of the spring. Gather one of the flowers which are snugly nestled amongst the broad and wrinkled leaves, and at the end of its slender stalk will be seen a narrow green five-pointed five-angled funnel, which is the calyx or flower-cup, the outermost of the series of parts which constitute the flower, and which in most flowers, being green, may be readily distinguished. Within this stands the corolla, the yellow attractive part of the flower. In this case, if gently pulled, it will he found to come away all in one, and hence it is called monopetalous, or consisting of one petal, the parts of which it is constituted having, as it were, cohered to form this one piece. This is the condition in which the corolla is found throughout the Monoprrats, one of the larger groups in which plants are classified. Sometimes these Mo- nopetals are very irregular in form, but in the Primrose we have an example of one which is perfectly regular. Let us see of what it consists :—first, there is a long slender tube, which is straight; then there is a broad flat expanded part or limb, and that consists of five lobes or segments of similar size and form, and spreading equally, so that we may infer that the corolla is here formed of five equal coherent parts. We have thus a. corolla which is perfectly regular or sym- metrical in plan. The particular form a corolla assumes has, in most cases, a particular name; that of the Primrose is called hypocrateriform, or salver-shaped, but other regular monopetalous forms will be found by-and-by, in summer, in the funnel-shaped corollas of the Convolvulus, or the bell- ILLUSTRATIONS. 3 shaped corollas of the Campanula. We will not now stay to examine the Primrose further, but pass on with the remark, that on the inside of the corolla-tube are fixed five stamens, and just visible in its mouth is the round-headed stigma on its long slender stalk, looking very much like a pin dropped into the tube. The Primrose illustrates one form under which the large Dicotyledonous group, to which we shall have to recur, is developed. At a very early period, too, comes the Snowdrop,* one of the Amaryllidaceous family, a doubtful wilding perhaps, but here and there established in meadows and pastures, in seem- ingly wild localities: always welcome as “ the early herald of the infant year,” or, as Mrs. Barbauld calls it, “ the first pale blossom of the unripened year,” its pendent bells rivalling in purity the snow-flakes which not unfrequently fall around them. The grassy leaves and pendulous flowers of the Snow- drop are familiar to every one; the three white outer concave segments of the latter form the sepaline divisions of the pe- rianth, and represent the calyx, and the three inner, which are smaller and tipped with green, form the petaline divisions representing the corolla. In the inside are six stamens ; while the ovary or immature seed-vessel is formed entirely beneath the other parts of the flower, that is, below the actual base of the parts though in reality uppermost as the flower hangs: hence it is called inferior. We have in the Snowdrop an excellent illustration of ano- ther large group or class of plants—the MonocotyLevons, so named because their seeds are furnished with only one in- stead of the two cotyledons or lobes which are found in the larger proportion of the flowering plants, hence called Dicoty- ledons. ‘Take one of them for examination. ‘There is first a * Galanthus nivalis— Plate 6 B. 4, SPRING FLOWERS. bulbous stem or base to the leaves and flower-stalks: this is frequent among Monocotyledons, but not characteristic. Then the leaves are ribbed with veins all running side by side lengthwise, a peculiar feature by which the group may in all ordinary cases be recognized. Next. the flowers consist of six divisions, which is a nearly certain mark of a Monocotyledon. There is no separate calyx and corolla in the Snowdrop as in the Primrose, but the two will be found blended together, all the parts having become corolla-lke. When thus combined, the calyx and corolla form what is called a perianth ; three of the segments, which will be found to be exterior, represent the calyx, and are hence called sepaline divisions, and three are interior, representing the petals, and are hence called petaline divisions. These features—the straight-veined leaves, and the parts of the flowers arranged in threes or multiples of three— are generally distinctive of the large and important class of Monocorytrpons, also called Enpocrns, from the internal manner of accretion in their stems. The Crocus,* too, is one of Spring’s earliest harbingers, starting up almost as if by magic from the scarce-thawed earth, and making it resplendent with the richest colours al- most before the snow has vanished from the surface. The Spring Crocuses, though blooming at so early a period, present little other difference compared with those kinds which bloom in autumn. This favourite flower is a well-known representa- tive in gardens of the Iridaceous family, and is so far natura- lized in meadows and pastures in some parts of England, as to claim admission amongst our field plants, though perhaps not a true aborigine. It has a kind of solid bulb called a corm, and produces grassy leaves. Its large funnel- or vase-shaped six-lobed flowers, expanding in the sunshine, purple in those * Crocus vernus—Plate 6 A. - ILLUSTRATIONS. 5 which occur in the wild state, differ from those of the Snow- drop in being erect instead of pendent, but like the latter plant, the Crocus belongs to the great family of Monocotyledons, and to that series in which there are six coloured leaves to the pe- rianth or flower, these being combined at the base into a long slender tube; above they are scarcely distinguishable into an outer and an inner series, each consisting of three leaves, re- presenting the sepals and petals which were found to exist in the Primrose, where however they occur in a state of cohesion, the parts it will be recollected being united into a tubular calyx and a monopetalous corolla. The Crocus flowers have three stamens, and a stigma which is dilated and fringed at the top. The long slender tube of the periauth, which is in fact the stalk-like portion that at length becomes visible, is a good deal hidden by the leaves and sheathing membranes which emerge with it from the ground ; and the ovary, or young seed-vessel, is buried amongst the bases of the leaves. And now having briefly adverted to these earliest of the early of Flora’s offerings, which besides have afforded illustra- tions of the groups of Monopetalous and Monocotyledonous plants, we will proceed to glance in something like order at a few other examples representative of the Vernal Flora, which have been selected as the subjects of our illustrations. We commence with the DicoryLepons, called also Exocens, from the external manner of accretion in their stem, a large group, known generally by their net-veined leaves, and sharing with the Monocotyledons and Cryptogams the whole Vegetable Kingdom. At a very early period of the year, in moist woods and pas- tures, the surface of the ground will be found whitened with 6 . SPRING FLOWERS. a multitude of small starry blossoms of a small Ranunculace- ous plant. These are the blossoms of the Wood Anemone,* a dwarf herb, which has fleshy underground stems, from which spring up three-parted leaves and white cup-like flowers, below which latter an involucre or guard of three leafy parts resem- bling the true leaves is placed. Here, then, we have an illustration of a very different kind of flower from any of those which have been previously noticed. We have in fact one of the group of Polypetalous (that is, many-petaled) Exogens or Dicotyledons. Passing over all but the flower itself, what do we find? There is first a single row of what look like petals and appear to form a corolla, and within these is a large tuft of small yellowish bodies, which are the stamens and pistils. The petal-like bodies are how- ever in reality a coloured calyx, divided into many (about six) separate pieces or sepals, standing in place of petals, which © are entirely wanting. It is because such flowers have several distinct and separate parts to form their floral envelopes that they are called polypetalous, and our subject represents one condition of a large group, in which however both calyx and corolla are generally present. The rule is, that when only one floral envelope is found—the calyx and corolla are called floral envelopes—it is regarded as a calyx, whether it be green or coloured. In our Wood Anemone the pistils will be found to be numerous and distinct, and they consequently grow up into a group of distinct fruits or carpels, which contain each one seed. ‘This little spring flower can only be seen in perfec- tion when the atmosphere is dry, for in humid weather and at night the petal-like calyx closes up. A purple-flowered variety, with smaller flowers, generally formed of eight, rarely of six, narrow-ovate sepals, of a uni- * Anemone nemorosa—Plate 1 A. ILLUSTRATIONS. 7 form deep purple, has been lately found at Pinner, and also at Chislehurst. | Growing in wet open places, and amongst the earliest of wild flowers, is another Ranunculaceous plant, petal-less like the foregoing, namely, the Marsh Marigold,* a specious-looking stout-growing perennial, with bold roundish leaves, hollowed at the base in what is called a heart-shaped form, and whose bright golden flowers have much the structure of those of the Wood Anemone, but are larger and more conspicuous from being elevated on a tall branching stem. They have a varying number of about five or six coloured sepals and no real petals, a tuft of numerous stamens, and a variable number of car- pels or fruits, each one containing several seeds. Somewhat resembling this, and one of the same group, but dwarfer, and having both calyx and corolla present, so as to form a com- plete regular polypetalous or many-petaled flower, which for the purpose of comparison it may be useful to examine in connection with the Marsh Marigold, is the Lesser Celandine (Ranunculus Ficaria), found abundantly in moist waste places, and easily recognized by its glossy-looking yellow star-like flowers, and its white-mottled angular-lobed leaves. The Ladies’-smock,+ during the months of early spring, imparts its own blush to the surface of moist low-lying meadow land, among the herbage of which it grows up. This plant, also a Polypetalous Exogen, sometimes called Bitter- eress and Cuckoo-flower, is a dwarf herb, growing erect to about a foot in height, and having pinnate leaves ; the flowers are large and showy, and will serve to illustrate the structure of a considerable polypetalous regular-flowered group or Order, known as Cruciferous plants, or Cross-bearers, from the cir- * Caltha palustris—Plate 1 B. + Cardamine pratensis—Plate 1 C. 8 SPRING FLOWERS. cumstance of their flowers having four equal petals arranged in opposite pairs so as to form a cross. The group may be known by this circumstance, and by having six stamens, two shorter than the rest. This Cruciferoys Order, besides being an extensive one, is important, containing, amongst other subjects of utility, the whole Cabbage family. To the same Order belongs the Wallflower,* “ grey ruins’ golden crown,” a flower well known in every garden, and prized for its delicious fragrance, found here and there in a wild or semi-wild state on walls and old buildings, or in rocky situations, generally near habitations. In the Wallflower we have a plant of subshrubby growth, furnished with simple leaves, and its yellow or reddish-bronzy flowers are succeeded by what are called siliquose pods containing the seeds, as is also the case with the Ladies’-smock. In both these plants the inflorescence or collection of flowers forms a kind of co- rymb in the earlier stages, lengthening out by degrees into a more or less elongated raceme. This flower has been made the emblem of friendship in adversity, because, though Time, the rude and sacrilegious despoiler of consecrated places, may waste and overthrow the structures of the past, and leave them uninhabited, the Wallflower, “‘mantling o’er the battlement,” still lends a melancholy grace “to haunts of old renown.” And then, who does not know the Violet,t the very emblem and personification of sweetness—sweeter, as Shakspere says, than ‘‘ Cytherea’s breath”? This lovely plant is common on banks and under hedges, a dwarf herb, with heart-shaped leaves and polypetalous flowers, which, “ kissed by the breath of heaven, seem coloured by the skies.’? They are of a dis- tinct type from any of the foregoing, and have a separate * Cheiranthus Cheiri—Plate 1 D. + Viola odorata—Plate 2 A. ILLUSTRATIONS. 9 calyx and corolla, the former consisting of five green sepals, the latter of five coloured usually purple or white petals, which form an irregular flower, two of the petals being placed to form the upper half, and of the remaining three which form the lower part, the lowest is extended backwards at the base, pro- ducing a kindof spur. The Violet has therefore an irregular polypetalous spurred corolla. There is also a peculiarity in the anthers, which are five in number, and are more or less closely joined in a sort of ring around the ovary, the two lowermost of the five being, like the lower petal, lengthened into a spur. These spurred polypetalous flowers serve to distinguish the Violets from all other British plants except the Balsams, which are known by having only three sepals and three petals, all coloured. The Sycamore* illustrates another family of the same group—the Polypetalous Exogens, namely, the Aceraceous or Maple family. This is a well-known tree, very extensively planted in this country, seeding readily and springing up from self-sown seeds so freely that it may be regarded as naturalized here, though the mountains of central Europe and western Asia have been its ancient home. This tree, which flowers early in spring, puts forth broad palmately-lobed leaves, and bears rather inconspicuous flowers in pendent clusters, which look not unlike immature bunches of small grapes. The in- dividual flowers consist of five small green sepals, five small green petals, and about eight stamens inserted on a thickened disk around the ovary. The fruit of these plants consists of two carpels, each extended into a wing at top; they are popu- larly called keys, but in technical language such a fruit is called a samara. Along with the Wood arenas Ls already adverted to, may * Acer Pseudo-platanus—Plate 2 B. 10 SPRING FLOWERS. be found the dwarf and unpretentious Wood Sorrel,* a lovely little wilding, representing the family of Oxalidaceous plants. This has peculiar knotty fleshy stems, and trifoliate leaves like those of the clover. It has also polypetalous (here five- petaled) regular flowers, in which both calyx and corolla will be found, the calyx consisting of five green sepals, the corolla of five equal obovate white petals; within these are ten sta- mens, half of which are as long again as the others, and five separate styles surmounting the ovary. This elegant little plant is maintained by some antiquaries to be that which fur- nished St. Patrick with his illustration of the doctrine of the Trinity, though others contend for the Trefoil or Clover, which ‘is now more commonly adopted as the Irish Shamrock. The foregoing plants (excepting the Primrose, the Snow- drop, and the Crocus) all belong to a primary division of the Dicotyledons or Exogens, called THaLamirtorgs, and they have these distinguishing marks in common :— - (a) The petals are distinct from the calyx, and from each other: very seldom absent. (6) The stamens are hypogynous, that is, they have their point of attachment below the ovary, which latter is the young seed-vessel. We have next to consider one or two examples of another great subdivision of the Dicotyledons, called CatycirLorEs, which has these peculiarities :— (a) The petals are usually distinct. (6) The stamens are perigynous, that is, appearing to grow on one of the organs surrounding the ovary, either calyx or corolla; or epigynous, that is, apparently growing from the summit of the ovary itself. * Oxalis Acetosella— Plate 2 C. ILLUSTRATIONS. ll Of this group we find in very early spring an illustration in the well-known Red Currant* of our gardens, a member of the Grossulariaceous family, which, though a cultivated plant, is frequently found in a wild state, both in Scotland and in the north of England. This, as is well known, is a dwarfish branching shrub, bearing palmately-lobed leaves, and racemes of small greenish flowers, which latter consist of a calyx adherent to the ovary and divided into five sepals, a corolla consisting of as many small scale-like petals placed at the base of the segments of the calyx, five perigynous stamens, and an inferior ovary, which becomes a succulent berry, varying in colour. Here also may be referred the Meadow Saxifrage,} a common but very pretty species, representing the Saxifragaceous family, and which in early spring is found, sometimes very abundantly, in meadow and pasture land. Itisa perennial herb, producing underground a number of small fleshy tubers from which its stems arise. The lower leaves are kidney-shaped and lobed, and the stem grows upright six inches to a foot in height, bearing towards the top a few large white flowers, which have a calyx adherent to the ovary to about its middle, then sepa- rating into five lobes, five perigynous petals, ten perigynous stamens, and a two-celled ovary with two distinct styles. Another of the great divisions of the Dicotyledons, the Monoprerats, or Monopetalous flowers, has been already ad- verted to in referring to the Primrose, but we have other illustrations to offer. The distinguishing features are :— (a) The petals united, at least at the base, into a single piece. * Ribes rubrum—Plate 2 D. + Sazifraga granulate—Plate 3 A. 12 SPRING FLOWERS. (6) This monopetalous corolla either epigynous, bearing the stamens; or altogether distinct from the stamens; or hypogynous, bearing the stamens. Of the first of these subdivisions we have some early-flower- ing examples in the family of Composites, or Compound flowers. Among them is the common, well-known, golden-flowered Dandelion,* to be found everywhere, and combining in itself the characters of a gay spring flower, a troublesome weed, and a valuable remedial agent. This plant has a thick, fleshy tap- root, from the crown of which spreads a tuft of oblong run- cinately pinnatifid leaves, among which spring up numerous hollow peduncles, bearing, not a large yellow flower as is the vulgar notion, but a head of numerous yellow flowers of pecu- liar character. Itis the faet of their bearing numerous flowers in one head, and so as to seem to constitute a single flower only, that has procured for the large family to which the Dan- delion belongs, the name of Composites, or Compound flowers. Let us examine one of these a little more closely. At the top of the stalk are two or three rows of crowded green scaly leaves, of which the innermost are erect, and the outer ones recurved ; these constitute the involucre or guard-leaves, which in the Composite plants are always found surrounding the flower-heads, and the parts of which are called bracts or scales. The top of the stalk is expanded into a broadish flattened sur- face, which the involucral leaves fence round, and on this sur- face, which is called the receptacle, the flowers are closely packed side by side. The Dandelion belongs to a group of Composites in which the flowers are all alike—all ligulate or strap-shaped, and hence the group has been named Ligulates. Take up one of the flowers,—they are here properly called florets, or little flowers,—and let us see of what it consists. At the base is a * Leontodon Taraxacum—Plate 3 B. ILLUSTRATIONS. 13 compressed reversed ovate fruit, roughish on the upper part ; then comes a little stalk, and a cylinder of long fine hairs called the pappus, from out of which at top issues the long yellow limb of the floret. By-and-by, as it gets older, the little stalk will lengthen into a long slender shaft, and the cylinder of hairs will expand like the rays of an umbrella, and in this way will float away the seeds. But the corolla: this is attached just above the pomt where the rays of the pappus diverge, and consists of a slender tube which some distance up is split on one side, and so forms the flat strap- shaped ligulate limb. Out of this tube emerges the two stig- matic branches, just beneath which the linear anthers are united into a sheath surrounding the upper part of the style. This cohesion of the anthers into a tube enclosing the style is one of the marks of a Composite flower. But we have another illustration, which will serve to explain a different set of these Composite flowers, called the Corymbi- fers from their heads being generally in corymbs—the Daisy,* Burns’s “ bonny gem,” which is almost ever and everywhere in blossom. The Daisy is a dwarf perennial herb, with a spreading rosulate tuft of obovate or spathulate leaves, from among which arise the numerous slender stalks, bearing not however a corymb, but a single or solitary head of flowers. Here, the involucre consists of about two rows of green bracts, and within them, at the outer edge of the receptacle, is a row of ligulate female florets, with a very short tubular portion at their base, from whence issues the two-branched style, these having no stamens. These are the ray florets. The other part of the receptacle is filled with small tubular funnel-shaped equal florets, which are hermaphrodite, having both stigmas -and anthers. These small tubular disk florets form. the yellow * Bellis perennis— Plate 3 C. 14 SPRING FLOWERS. centre of the Daisy flower-head. ‘The manner in which the poet Burns apostrophized this ‘‘ modest crimson-tipped flower,” while following the plough, and lamenting over the destruc- tion he was causing it and could not avoid, is singularly pa- thetic—“ the share upturus thy bed, and low thou lies.” Of the subdivision of Monopetals in which the stamens are distinct from the corolla, examples will be found in the spring- blooming Vaecinium or Whortleberry family. The division in which the corolla is hypogynous, bearing the stamens: in other words, in which the flowers are peri- gynous, is well illustrated by the Primrose, already adverted to in our opening page. Another illustration is afforded by the Lesser Periwinkle,* one of the Apocynaceous or Dog- bane family, found occasionally in hedges and woody banks, and commencing to flower in spring—ay, sometimes very early in the year. This is a perennial, with long trailing stems, clothed with opposite ovate-oblong leaves, and producing also short erect flowering-branches, which bear solitary axillary flowers ; these have a free calyx with five narrow deep divi- sions ; a monopetalous corolla, in which the tube is almost campanulate, and the limb consists of five flat spreading seg- ments, having a lateral twist; five stamens enclosed in the tube of the corolla; and two ovaries, distinct at the base, but connected at top by a single style, terminating in an oblong stigma, contracted in the middle. The twisted corolla and pulley-shaped stigma are special marks of the Apocynaceous family, to which the Periwinkle belongs. The Buckbean,} an aquatic plant, found in bogs and shallow pools, and famous for its tonic properties, comes into flower soon after the Periwinkle, and affords another example of the * Vinea minor—Plate 3 D. + Menyanthes trifoliata—Plate 4 A. ILLUSTRATIONS. 15 same subdivision, belonging to another natural family, that of the Gentians. . It has stoutish creeping or floating stems, with strong coarse roots, and forming at the end a tuft of leaves, consisting of three obovate or oblong leaflets, set on a long stalk, which is sheathing at the base. The flowers come in erect racemes, and each consists of a short calyx with green lobes, and a bell-shaped corolla, deeply five-lobed, the lobes spread- ing or even reflexed, white tinged with red, the inside ele- gantly fringed. The flowers have five stamens joined to the tube of the corolla, and the fruit is a capsule opening in two valves. We must pass on to another great division of Dicotyledons in which the structure is of a simpler character. These are the Monocutamyps, having Monochlamydeous or one-coated flowers. They form a considerable group, comprising some few showy families, and including many others in which the blossoms are quite inconspicuous. Here there is normally not more than one floral envelope (sometimes none) to the stamens or pistil, which are the essential organs of the flower. The envelope when present is called the perianth or perigone, and is im reality a greeu or coloured calyx, the corolla being constantly wanting. To this series belongs the gay but poisonous Mezereon shrub,* one of the Thymelaceous family, a very early-blooming plant, found in woods and thickets. The branches of this dwarf deciduous shrub are clothed with the little clusters of flowers, “blushing wreaths investing every spray,” while yet the young leaves are undeveloped. The latter appear later, and are ob- long or lanceolate in form. The flowers have a short broadish tube to the perianth, a limb of four spreading lobes, and eight * Daphne Mezereum—Plate 4 C. 16 SPRING FLOWERS. stamens which are attached in two rows to the inner face of the tube. The flowers are purple or in some plants white, very sweet-scented, and succeeded by a “ vesture gay” of red or yellow berries, containing a single seed; this was present in the form of a pendulous ovule in the urn-shaped ovary, which stood free within the base of the perianth. Of the same Monochlamydeous division, and growing in si- milar habitats, but of much more frequent occurrence, is the Wood Spurge,* representing the varied and extensive Euphor- biaceous family. This plant is in early spring conspicuous on account of its umbels of light yellowish-green bracts. It has almost woody stems, of a reddish colour, bearing narrow- oblong leaves, above which the umbel of five or six principal brauches is produced. These bear floral leaves or bracts in pairs, of a yellowish-green colour, and between each pair a small green body, apparently a flower but really a flower-head, consisting of a small cup-shaped involucre resembling a peri- auth, having four minute teeth, and alternating with them as many horizontal yellowish glands, which are here crescent- shaped ; within these are several stamens each bearing a pointed filament and a minute scale at its base, thus showing them to be distinct male flowers; while in the centre is a single female flower on a recurved stalk, consisting of a three- celled ovary and a three-cleft style. This ovary grows into a fruit of three carpels, called cocci, whence the fruit is called tricoccous. Of a different character, still Monochlamydeous, is the Wych Elm,t the common wild Elm of Scotland, Ireland, and the north and west of England, a representative of the Ulmaceous family. Here we have a deciduous large-grow- * Ewphorbia amygdaloides— Plate 4 D. + Ulmus montana—Plate 5 A. ~ ILLUSTRATIONS. 17 ing tree, whose branches are, during summer, clothed with broadly-ovate pointed leaves. In early spring however, before the leaves appear, the buds along the twigs burst open, and each developes a dense cluster of reddish flowers surrounded by brownish bracts that soon fall away. The flowers are mostly hermaphrodite, and consist of a bell-shaped perianth with from four to six teeth and as many stamens. ‘The ovary is flat, with two short diverging styles, and is succeeded by a flat thin leaf-like or winged seed. The common Sallow,* one of the Amentiferz or Catkin-bear- ing family, is of a different character, though part of the same great Monochlamydeous division of Dicotyledons. The large family of Sallows and Willows consists of trees and shrubs, with unisexual flowers growing in catkins in early spring on the leafless twigs, the male catkins being produced on distinct plants from those which bear the females. The common Sallow itself is a tall shrub with broadish-ovate or oblong greyish downy leaves. The catkins of the male plants are cylindrically ob- long, an inch long or more, formed of overlapping silky-hairy scales, but no perianth ; in the axilof each scale are placed two stamens, which are longer than the scale itself, so that the fully developed catkins are rather conspicuous from the crowded prominent yellow anthers. The female catkins are longer and narrower, and have in the axils of the scales, instead of a pair of stamens, a silky ovary, which tapers into a longish beak and is terminated by the forked stigmas. Notwithstanding the bright gleam of vegetable beauty which at this early season the Sallow affords in its favourite haunts by the streamlet’s margin, in moist coppice woods, or overhanging a watery ditch, it may have probably escaped the attention of many who may been attracted by these golden ‘ palms’ of * Salix Caprea, Plate 5 B. 18 SPRING FLOWERS. Easter-tide, that no fruit is ever borne by these specious catkins. Yet it isso. Near at hand however will be found other bushes with other catkins, without the alluring hue of gold, and these on closer inspection will be seen to consist of the pale-green silky ovaries or young fruits, surmounted by the forked stigmas, intended to catch the dust that flies off from the catkins of the golden hue, which dust is borne to the ovary-bearing or female plant by the agency of insects or on the wings of the wind. Thus even the rude blast, annoying though it sometimes may appear to be, has its appointed office to perform in Nature’s laboratory, one of which is to carry the fertilizing powder or pollen from plant to plant, and thus to secure the fulfilment of the appointed law by which each herb and tree bears seed after its kind. The remaining principal division of the Flowering Plants, is that which is called Monocotyledons, the chief peculiarities of which have been already pointed out in referring to the Snowdrop and Crocus. The two flowers just named belong to the regular-flowered natural families in which the ovary is inferior, or developed beneath the other parts of the flower, which thus appear to grow from the top of the ovary. Our spring flowers however afford us some illustrations of the Orchi- deous family, a peculiar series of Monocotyledons in which the flowers are remarkably irregular, and also of the Lilia- ceous family, a natural group of regular-flowered Monocoty- ledons in which the ovary is superior, the other parts of the flower being developed from beneath it, so that it is enclosed by them. Let us examine more closely the specimens of the Orchida- ceous family, first taking the Spotted Palmate Orchis of our ILLUSTRATIONS. 19 meadows.* The flowers in this family are of very singular structure. As in most other Monocotyledons, they are made upon a trimerous plan: that is, the parts are in threes; and, as in the majority of the petaloid division of Monocotyledons, the perianth is six-leaved: that is, twice three organs are brought together in close association, but here they acquire great diversity of character. In the Spotted Palmate Orchis, which has an upright stem, furnished below with spotted simple narrow elongate leaves, and terminated by an erect spike of spotted pink flowers, the three outer parts or sepals are nearly alike, and of a narrowish or lanceolate form, while the inner series of three consists of two convergent petals, which resemble the sepals but are shorter, and a lip which is much larger, three-lobed, entirely different from the rest. In the centre, opposite to the lip, is another part called the column, which is a fleshy body formed by the combination of one stamen with the pistil. Theoretically three stamens should be present, but in the Orchis two of these are con- stantly abortive, and the central one only is developed. The anthers in the whole family are very peculiar in structure. This plant like many other orchids has a pair of fleshy tubers or tuberous roots, one of which becomes wasted by the deve- lopment of the current year’s growth, while the other is form- ing for the succeeding season. The Lady’s Slipper,t another of the Orchids, shows some variations of structure from that just noticed. It is larger- growing, with ovate pointed ribbed leaves. The flower-stems are a foot and a half high, supporting one or rarely two large handsome flowers, of which the upper or dorsal sepal, opposite the lip, is broadly lanceolate, and there is a similar one formed * Orchis maculata—Plate 5 C (misnamed mascula). t+ Cypripedium Calceolus—Plate 5 D. Cc 2 20 SPRING FLOWERS. by the combination of the two lateral sepals behind or beneath the lip, while the two petals are narrower, spreading right and left: these all being of a deep brownish-purple. The lip is a large inflated pouch-shaped body, and is compared to a a slipper; it is yellow, variegated with purple. The column is broadish, and much shorter than the petals; and in this case the central stamen is abortive, and the two lateral ones are perfect. The Spring Squill,* a regular-flowered Monocotyledon, and one of the Liliaceous family, is a delicate little bulbous plant, found in sandy wastes and pastures, especially near the sea. It has narrow-linear leaves, and a flower-scape bearing at top a short raceme of small blue starry flowers. The perianth of these flowers is composed of six nearly equal spreading seg- ments, all coloured alike, and within them close to their base are inserted six stamens, one opposite each segment, the centre being occupied by the ovary. This is a superior ovary, the other parts of the flower being developed exterior to and beneath it. Another example of a spring-flowering Liliaceous plant, also regular-flowered, is afforded by the Bluebell,+ the “ shade- loving hyacinth” of the poets, a pretty bulbous plant, very abundant in Britain, in woods, hedgerows, and other shady places. This plant has broadish-linear leaves, and a flower- stem about a foot high, bearing a terminal one-sided or nod- ding raceme of pendent flowers, each flower having a small leafy bract at the base of its pedicel or stalk. The perianth is tubulose, the segments united for a short distance at the base, spreading only at the top where they become recurved. It is usually of a deep blue, though in some cases white, or * Scilla verna—Plate 6 C. + Hyacinthus non-scriptus—Plate 6 D. ILLUSTRATIONS. 21 more rarely pinkish. It is sometimes referred to the Scilla family, but a comparison with the foregoing will show con- siderable difference between them. This flower is occasionally called Harebell: a name which is more appropriately given to the little Campanula rotundifolia. The Hyacinth of the an- cients,— which was named in commemoration of a comely youth, Hyacinthus, who was accidentally killed by Apollo, and which bore certain lines or marks on its petals, in allusion to the absence of which our native species was called non- scriptus,—was made by the Greeks the emblem of Death; and hence an American poet has taken it as the symbol of sorrow: “the deep blue tincture that robed it seemed the gloomiest garb of sorrow.” Another poet has called it the “sublime Queen of the mid-May.” And with this well-known and favourite flower we close our sketch of the illustrative examples of the flowers of the spring season. In the succeeding pages we shall give a more com- plete and formal, as well as classified enumeration of the prin- cipal kinds of wild plants which blossom during the early por- tion of the year. The examination of these, as day by day they become unfolded, will, we hope, prove an agreeable and instructive pastime to many readers, and give them an in- creased zest for the search after those which are yielded by the seasons that follow.
