Stems have two principal wavs of fiimbhn;, by twining bodily around tlie supporting object ; or by the aid of tenctnli, modif ed brandies or leaves wliicli serve as holdfasts, as in the X'irginia Creeper. Tlwrm ari; mixlified branchc.-;. They are doubtless designed to protect the plant against animals that would strip it of its bark or leaves, if undefended. l.uives are appendages of the stem, whicli serve as the digestive organs of the plant. They assimilate the crude sop of the plant into material for building up its tissues. Leaves are arranged on tlie stem in two principal ways. They are aUiynali\ when tliere is but one at each ioint; and w/wrlcti, wlien there are more than one. \\'hen the whorl consists of but two leaves, they are said to be opposili . Tiie lanre usually ilat part of the leaf is called the blade. The stalk wliicli bears the blade is the f^etiolc. The two small blade-like bodies at tlie base of the petiole are the .f/ii/«/«'.f (8). When the petiole is wanting, the blade is sessile. The stipu'es are often absent or inconspicuous. There are two principal modes of vciniug in leaves. When the veins braiidi again and again, and the branches run together so as to form a network or mesii, the leaf is iiel-vehted (q\. When the veins run side by side without seeming to branch or run t(jgellier, the \cAi k paralUl-vfiueti {\o). Net-veined leaves arc J eti/ /if >■ venial ( 16) when the secondary veins start from a principal vein nrining through the o'litre of llie leaf from base to apex, the midyiii. 'I'liey -axm palmately-viined (qi when several veins of about equal si/e start togellier from the base of the li:af and run out toward the margin like radii of a circle. There is great diversity in the general outline of leaves. Some of the more common forms are: Liitfar.^ comparatively narrow and of about the same width from one end to the other ( 1 1); f^^/cw;', of same outline, but broader; lamccdale, narrow but broader at base and tapering toward the apex (12); elliptical, oblong or linear, but narrowed at both ends; cew/f, egg-shaped, broader at ba.se and narrowed toward apex (13); orbicular, rounded or circular in outline (14); oblanceolatc, lanceolate reversed, that is, broader at apex and tapering toward base; spatiilati, oblanceolate, with the narrowing toward the base more abrupt ( 15I; obovate, the reverse of ovale (i6). The apex of tlie leaf may be aciiininalc, ta|)eriiig into a point \\2\\ acute, more abrujitly ])ointed (17); f'/'///.vv, not pointed, rounded (13); tiuncate, as if cut off; cmaroinatc. with an iudeutatiou in the margin corre- sponding to the end of tlie midrib (18); nbcordalc, witli the indentation deeper. Tlie first four terms apply as well to the base of the leaf Other terms used in describing the ba.se are : cordate or licar /-shaped, tlie two sides of the leaf coming upward so as to leave a notch at the base (19); reniform, with a deeper and more rounded indentation or sinus (9); auriculate, with the two sides of the leaf prolonged at base into nmnded lobes or ears (20); sairittate, with these lobes acute and pointing downward ( 2 1 ), //.ziAfA-, with the lobes acute and pointing outward (17); peltate, when tiie lobes are grown together, so that the petiole .seems at- tached to the middle of the \c\xl \\.\); perfoliate, when the leaf is sessile on the stem and the b.ise has grown around No. 19.

Compound Idtvcs have tiie blade split np into separate parts or kallits (30). When tlie leaflets are arranged like the veins in a feather-veined leaf, tlie leaf is pinnate (30). When arranged like the veins in a lialmately-veined leaf, the leaf \s />>i/niatc (31 1. Tile divisions of a compound leaf may be further divided, so as to make the leaf twice c()m])oiind, or three times, or even more. Sl)ecial forms of lea\es serving other tuiu'tions than those of vegelaticn an- sometimes met with. .Some- times the end k-atht of a pinnalo leaf is changed into a tendril to aid tlie idaiit in climbing (^o). The tlcshy scales of /)iil/is (;),iii v.liicli food-matter is stored, are leaves. So are the thinner scales of wintcr-huds, occurring on most trees and shrubs. The most extraordinary forms of leaves are tho.se of the so-called /nstrthnyoua Plants. Here the leaves are designed for the purpose of eiitrapiiing insects and assimilating them as food for the plant. A common example is the Sarracenia Purpurea or Side-saddle Flower. This has the margin of the leaf folded together so as to form a "pitcher," closed at the bottom, op.:: at the lop (;,2). In some sonthern Sarracenias the tip of the blade curves over .so as to form a lid for the pitcher. The piiclier contains a sticky liquid, in which intrnding insects arc drowned. In another group of insectivorous ])laiits, represented witli 11s by the little sundews of the bogs, there is .a different jireparatioii f()r a warm nelcome to insect guests. The leaf is fringed with gland-tipped hairs, which may be likened to the tentacles of a eiutle-lisl). When the unsuspecting insect alights 011 the leaf the surface is irritated, causing the tentacles to bend in toward the middle. Tims the cause of the disturbance is imprisoned and the iiourisliing part of its body is digested bj- the leaf Then the tentacles relax. That the insectivorous plant actually feeds on the insect which it captitres was proved coiielnsively by Darwin. He showed that plants of this kiii'l when furnished with insects grew mo-e vigorously than when insects were prevented from reaching them. /n/lorcsccncc is the m.inner of arrangement of flowers on the stem. Flowers are solitary or clustered. They may be borne on a special stalk, tlie />rditi(il>\ or they may be sessile, growing on the stem without aiiv such stalk. When flowers are in clusters, the stalk bearir.g the whole cluster is the fieduncle, while the stalk bearing each individual flower is the pedicel. The small haves growing on peduncles or pedicels, or on the main stem among the flowers, are called hiaets. They are usually smaller llian ordinary foliage leaves, and often scale-like. The principal sorts of flower clusters are: the raceme, consisting of a stalk or axis bearing i)ediceled flowers, forming a cluster usually considerably longer than broad (;,3l; the spike, a ra'-fine with sessile flowers (34); the corymb, a raceme with flokvers ou pedicels of different lengths, but all reaching to about the same level (35); the tNSI CTIVOKOU;.

The /ifai/ a corymb with nodicels very short or wnntiiig (37); the rt'/wc, differiiiir from tile .-orymb in that its uppermost and therefore innermost fiowersare the first to open (j8). The complete Hower consists of fom sets of parts— the j.>Kllen grain, wluii it alights on the .stigma, sends out a ininute tube which runs down through the style into tlie ovary. When the tube reaches an ovule, the process known as fertilization takes pl.ice. The nature of the jmicess is not anderstood. The result is that the ovules develop into .vivvA fiom whicli new ]).ants may arise, while the i)vary enlarges irit(j the /'«//. The term fruit is applied by the botanist, not merely to the ediiile kinds, like strawberries, but to every structure which contains the .seeds. The balls that are borne on the "sycamore," or button-wood tree, are as truly fruit as is the peach. A flower which has both stamens and pistils is perfect. If ic has only stamens it is staminate. If only pistils, it is pistillate. When a flo ler has all the members of one set of parts, <'.,(,'., all the st;iniens or all the petals alike, it is said to be ^-I'^w/rtr. Otherwise it is irregular . Most irrej^iilai Jloxvers have the parts arranged so as to aid in eross-Jertilization bv means of insects, as the flowers of the Orchids and of tiie I'va Family. Cross-fertilization is the carrying uf ])olleii, by the aid of insects, from one flower to tlie stigma of another, on the same plant or on a different plant of the same kind. The insect visits the flower in search of nectar or honey. He brushes against the anther and some of the pollen tails upon him. This he carries to the next flowei visited and deposits it on the stigma. It is undoubtedly an advantage to plants to have their flowers cross-fertilized, rather than to have the stigma receive polkn from the anthers of the same flower. Why, wo do not know. The orchids, to which our lady'.s-slipper and meadow-jjink belong, often have elaborate contrivances for aiding insect- friends to accomplish their useful task. Their flowers are always irregular (42). The f^aiuopetaloHS corolla has several special forms. These are: rotate or uheel-shaped, flat, and with hardly any contracted part or tube (43V, salver- foruieil. with a limb or border spreading out at right-angles to the tube (44); bell-shapeil, with the tube open and widening toward the summit, and with no distinct Vuuh (.\ej)\ fit nnel-shaped, with a narrow tuoe and comparative^v wide limb, like an ordin.iry funnel (.)6); tubular, with a narrow tube, not widening toward tlie summit, and no distinct limb; labiate, two-lipped, as in the Mint Family U;); ligulati, strap- shaped, as in the Chicory and most of the Sunflower Family (48).

A fonn occa.sionally occurs in which the flowers are pure white. The lupines are reprr-.ented in Kastern North America by '.wo .species. One, the plant figured h;re, is native from Canada to Florida. The other, Lupiiius villosus. is a native of tne s.andy pine-barrens of the Southern States. It has leaves of but a single leaflet. The pmls are strikingly conspicuous, bei-.i^ covered "ith long, silvery hairs. In the West, on the other hand, there are numerous .species, and it is often (piite difficult to tell one fjoin the other. All are very ornamental plants. The name lupinus is fnmi the Latin .../«$, .-. wolf, because these plants are suj. posed to exhau-t or devour the soil. The charge can hardly be brought again.st out sjiecies, which confine themselves to poor, sandy soil. Wood says of our plant : " It is often called .suu-dial, from the circumstance of its leaves turning to face the sun from moniing till night." LARGER YELLOW LADY'S-Sl IPPER. FLATS 1.

The largv. yellow lady's-s'-pper is to be met with on ri.h, womled hidsidcs. With it is often found the small yellov, lady's-slipt)er, which has a smaller flov,rer of a brighter yellow, and with a slight fragrance. Both species occur in Canada and in the Hasteni St.ites. They flower in May and June. Cypripedium is derived from two Oreek words and means " Venus' buskin " — a pretty name, truly. The spwific name refers t < the hairiness.

The deep green leaves and flowers of a dainty pink make a pretty con'.bination. The l)lossoms have a delicate, agreeable odor that cnhinces the attractiveness of the plant. Were it not so common, Jie sa|x;naria would Ik' prized by gardeners. It is not an injurious weed, rarely taking po.s.ses.sion of cultivated ground. It is certainly a more welcome addition to our w.iste g (Uiid flora than many of its compatriots. The Bouncing Het is spreading rapidly in this couj.try. It was at one time much i)lanted m gardens, which has aided it in estal)lishing itself far '.nd wide. The pink family, to which the saponaria lielongs, contains .some of our most beautiful flowers and some of our most insignificant wet.'ds. Among our native plants the catch-flies, with their flowers of brilliant scarlet, pink or white, are prodigal of ch.ami. Saponaria means soapy, so named l)ecause the juice of tile plant forms a lather when mixed with water ; officinalis indicates that the plant is used in medicine. It is the large acrid r that it is a difficult matter to jmll tliem up. It is sometimes almost aquatic, the lower part of the plant being occasionally under water. The leaves are very long and rigid. The large, bright yellow flowers are singularly attractive, contrasting well with the more connnou blue flags. The rootstocks, like those of the blue flag, are used in medicine. They much resemble those of acorns calamus, whence the specific name, pseudacorus — false acorns. One of the showiest of the numerous luiropean s|iecies of iris, iris germanica. the common flag of gardens, is naturalized in Virginia.

Perennial, hairy or almost smooth ; stems deeumtient . neatly erect, four angled, leaxrs oppt^sste, ot^te-lanceolate, the tou-et on long, slender petwles, the uppermost neatly sessile, acute at each end, serrate, thin ; fiowet s in dense, axillaty clusters, small, white labtale. LTHOUGH several kinds of mint have been imported frotii Europe into this countrj*, we have but one native species in eastern North .\merica, the Canada mint. This is not a decidedly showy plant, .although the dark green foliage and the clusters of tiny white flowers are rather pleasing. The very liairj' form is less attractive, having a grayish asjiect. It has not the warm, aromatic fragrance of the peppermint and the six^armiut. Gray compares the (wlor of the ordinar>' form to tliat of pennyroyal, likening the odor of the .smooth variety to the horsemint, monarda. Nearly all the members of the mint family 1 ave little glands on the leaves, in which is .secreted a volatile oil. To this oil is due the strong and often delightful odor characteristic of these plants. ICvery one is familiar with the spicy {)eppermint, the aromatic sage, the fragrant thyme, the lemon-scented balm — ^tiud, among our own native plants, the jieculiar perfumes of the horsemint, the dittany and the American pennyroyal. Perhaps no other single family of plants furnishes such a v.aricty of odors. The Canada mint grows in low ground, esiiecially near the banks of rivers. It flowers in August and Septemlier. The stems usually lie on the grounds, rising at the ends. The name mentha is of mythological origin. According to the fable, a nymph was transfonned by Proserpine, the wife of Pluto, into the plant that now bears her name. ^ IRIS PSEUDACORU8.

' HE chicory i.s one of the many plants that have come to us from Europe. The number of these waifs that find, first a footing, then a home and often a kiiifrdom Oii our shores, is always increasing. Some are not unwelcome guests, but the greater part are our most troublesome and most persistent weeds. The rapidity with which sucli European plants as the common thistle, the dog-fennel, the pigweed and the purslane drive tnit onr native plants and take pos.ses.sion of fielils and waysides, would indicate that they have .some advantage over ours in the struggle for existence. vSuch is indeed the ca.se. The old world plants are favored because they leave their insect or otlier enemies behind them, when they crass the ocean. Ours have always their wonted drawbacks to contend with while engaged in an unetiual fight with the invaders. Thus the chicory has made itself a familiar object in waste places and at roadsides, often proving itself a most undesirable addition to our flora. It is well naturalized in northern districts, but is yet rare in the Soutli. The heads of pretty, azure-blue flowers open succe.ssively during the greater part of summer and autumn, " to match the sky," sings Emerson. The name Cichorium is of Arabic origin.
