Older flower with the stamens S anther is developed o n the c orolla dried up. erX2 dth e hairs before the filament, and when the latter is not produced, the anther is sessile, as in the mistletoe. article The filament is usually, as its name imports, filiform or threadlike, and cylindrical, or slightly tapering towards its is often, however, thickened, compressed and flattened in various ways, becoming petaloid in Canna, Marania, water-lily fig. 32; subulate or slightly broadened at the base and drawn out into a point like an awl, as in Butomus umbellatus; or clavate, that is, narrow below and broad above, as in Thalictrum.

In some instances, as in Tamarix gallica, Peganum Harmala, and Campanula, the base of the filament is much dilated, and ends suddenly in a narrow thread-like these cases the base may give off lateral stipulary processes, as in Allium and Alyssum filament varies much in length and in length sometimes bears a relation to that of the pistil, and to the position of the flower, whether erect or filament is springfield mass flower delivery of sufficient solidity to support the anther in an erect position; but sometimes, as in grasses, and other wind-pollinated flowers, it is very delicate and hair-like, so that the anther is pendulous fig.

The filament is generally continuous from one end to the other, but in some cases it is flower delivery toronto canada or jointed, becoming geniculate; at other times, as in the pellitory, it is is colourless, or of different in fuchsia and Poinciana, it is red; in Adamia and Tradescantia virginica, blue; in Oenothera and Ranunculus acrisyellow. article Hairs, scales, teeth or processes of different kinds are some times developed on the spiderwort Tradescantia virginica the hairs are beautifully coloured, moniliform or necklace-like, and afford good objects for studying rotation of the are usually articulated to the thalamus or torus, and the stamens fall off after fertilization but in Campanula and some other plants they florida flowers florists gifts delivery continuous with the torus, and the stamens remain persistent, although in a withered are produced in the whorl of delivery flower in philippine by cohesion of the filaments to a greater or less extent, while the anthers remain free; thus, all the filaments of the androecium may unite, forming a tube round the pistil, or a central bundle when the pistil is flower delivery toronto canada, the stamens becoming monadelphous, as occurs in plants of the Mallow tribe; or they may be arranged in two bundles, the stamens being diadelphous, as in Polygala, Fumaria and Pea; in flower delivery toronto canada case the bundles may be equal or frequently happens, especially in Papilionaceous flowers, that out of ten stamens nine are united by their filaments, while one the postericr one is free fig.

When there are three or more bundles the stamens are triadelphous, as in Hypericum aegyptiacum, or polyadelphous, as in Ricinus communis castor-oil. In some cases, as in papilionaceous flowers, the stamens cohere, having been originally separate, but in most cases each bundle is produced by the branching of a single there are three stamens in a bundle we may conceive the lateral ones as of a stipulary Lauraceae there are perfect stamens, each having at the base of the filament two abortive stamens or staminodes, which may be analogous to sometimes are adherent to the pistil, forming a column gynostemium, as in Stylidium, Asclepiadaceae, Rafflesia, and Aristolochiaceae fig.

article - Quadrilocular or tetrathecal anther of the flowering Rush Butomus umbellatus. The anther entire a with its filament; section of anther b showing the four loculi. The anther consists of lobes containing the minute powdery pollen grains, which, when mature, are discharged by a fissure or opening of some is a double covering of the flower delivery toronto canada - the outer, or exothecium, resembles the epidermis,and often presents stomata and projections of different kinds fig.

69; the inner, or endothecium, is formed by a layer or layers of cellular tissue fig. 69, cf, the cells of which der Botanik, by per FIG. - Spikelet of Reed Phragmites communis opened out. a, b, Barren glumes; c, fertile glumes, each enclosing one flower with its pale, d; the zigzag axis rhachilla bears long silky hairs. In the young state there are usually four pollen-sacs, two for each anther-lobe, and when these remain permanently complete it is a quadrilocular or tetrathecal anther fig.

Sometimes, however, only two cavities remain in the anther, flower delivery toronto canada union of the sacs in each lobe, in which case the anther is said to be bilocular or the anther has a single cavity, and becomes unilocular, or monothecal, or dimidiate, either by the disappearance of the partition between the two lobes, or by the abortion of one of its lobes, as in Styphelia flower delivery toronto canada and Althaea officinalis hollyhock.

Flower delivery to indonesia there are numerous cavities in the anther, as in Viscum and form of the anther-lobes are generally of a more or less oval or elliptical form, or they may be globular, as in Mercurialis annua; at other times linear or clavate, curved, flexuose, or sinuose, as in bryony and to the amount of union of the lobes and the unequal development of different parts of their surface an infinite variety of forms is part of the anther to which the filament is attached is the back, the opposite being the division between the lobes is marked on the flower delivery toronto canada of the anther by a groove or furrow, and there is usually on the face a suture, indicating the line of suture is often towards one side in consequence of the valves being stamens flower delivery toronto canada cohere by their anthers, and become syngenesious, as flower delivery toronto canada composite flowers, and in lobelia, jasione, c.

article The anther-lobes are united to the connective, which is either continuous with the filament or articulated with it. When the filament is continuous with the connective, and is prolonged so that the anther-lobes flower delivery 32258 to be united to it throughout their flower delivery toronto canada length, and lie in apposition to it and on both sides of it, the anther is said to be adnate or adherent; when the filament ends at the base of the anther, then the latter is innate or these cases the anther is to a greater or less degree fixed.

When, however, the attachment is very narrow, and an articulation exists, the anthers are movable versatile and are easily turned by the wind, as flower delivery toronto canada Tritonia, grasses fig.where the filament is attached only to the middle of the connective may unite the antherlobes completely or only is sometimes very short and is reduced to a mere point, so that the lobes are separate or other times it is prolonged upwards beyond the lobes, assuming various forms, as in Acalypha and oleander; or it is extended backwards and downwards, as in violet fig.

71, forming a nectar-secreting Salvia officinalis the connective is attached to the filament in a horizontal manner, so as to separate the two flower delivery toronto canada fig. 72, one only of which contains pollen, the other being imperfectly developed and connective is joined to the filament by a movable joint forming a lever which plays an important part in the Stachys the connective is expanded laterally, so as to unite the bases of the anther-lobes and bring them into a horizontal line.

article The opening or dehiscence of the anthers to discharge their contents takes place either by flower delivery toronto canada, by valves, or by the anther-lobes are erect, the cleft is lengthwise along the line of the suture - longitudinal dehiscence fig.

At other times the slit is horizontal, from the connective to the - side, as in Alchemilla arvensis fig. 73 and in Lemna; the dehiscence is then the anther lobes are rendered horizontal by the enlargement of the connective, then what is really longitudinal dehiscence may appear to be cleft does not always proceed the whole length of the anther-lobe at once, but often for a time it extends only other instances the opening is confined to the base or apex, each loculament opening by a single pore, as in Pyrola, Tetratheca juncea, Rhododendron, Vaccinium and Solanum fig.

74, where there are two, and Poranthera, where flower delivery toronto canada are four; whilst in the mistletoe flower delivery toronto canada anther has numerous pores for the discharge of the mode of dehiscence is the valvular, as flower delivery hong kong tulips the barberry fig.

75, where each lobe opens by a valve on the outer side of the suture, separately rolling up from base to apex; in some of the laurel tribe there are two such valves for each lobe, or four in some Guttiferae, as Hebradendron cambogioides the Ceylon gamboge plant, the anther opens by a lid separating from the apex circumscissile flower delivery toronto canada. article The anthers dehisce at different periods during the process of flowering; sometimes in the bud, but more commonly when the pistil is fully developed and the flower is either dehisce simultaneously or in the latter case individual stamens may move in succession towards the pistil and discharge their contents, as in Parnassia palustris, or the outer or the inner stamens may first dehisce, following thus a centripetal or centrifugal variations are intimately connected with the arrangements flower delivery toronto canada transference of anthers are called introrse when they dehisce by the surface next to the centre of the flower; they are extrorse when they dehisce by the outer surface; when they dehisce by the sides, as in Iris and some grasses, they are laterally dehiscent.

Sometimes, from their versatile nature, anthers originally introrse become extrorse, as in the Passionflower and Oxalis. The usual colour flower delivery toronto canada anthers is yellow, but they present a great variety in this are red in the peach, dark purple in the poppy and tulip, orange in Eschscholtzia, c.

Flower delivery to oak ridge nc colour and appearance of the anthers often change after they have discharged their functions.
