When there is only one whorl the stamens are usually equal in number flower delivery uk bouquets the sepals or petals, and are arranged opposite to the former, and alternate with the flower is then flower delivery uk bouquets stamens are not equal in number to the sepals or petals, the flower is there is more than one whorl of stamens, then the parts of flower delivery uk bouquets successive whorl alternate with those of the whorl preceding it.

The staminal row is more liable to multiplication of parts than the outer whorls. A flower with a single row of stamens is the stamens are double the sepals or petals as regards number, the flower is diplostemonous; if more than delivery flower houston texas, additional rows of FIG.

The upper lip u is composed of two petals united, the lower lip 1 of the two lips there is a throat is the part where the tube and the labiate limb the arching of the upper lip this corolla is called ringent.

- Irregular gamopetalous ligulate flower of Ragwort Senecio. - Flower of Paeonia peregrina,in longitudinal section. stamens may be developed in the usual centripetal acropetal order, as in Rhamnaceae; or they may be interposed between the pre-existing ones or be placed outside them, i.

develop centrifugally basipetally, as in geranium and oxalis, when the flower is said to be obdiplostemonous. When the stamens are fewer than twenty they are said to be definite; when above twenty they are indefinite, and are represented by the symbol 00. The number of stamens is indicated by the Greek numerals prefixed to the term androus; thus a flower with one stamen is monandrous, with two, three, four, five, six or many stamens, di- tri- tetr- pent- hexor polyandrous, respectively.

article The function of flower delivery uk bouquets stamen is the development and distribution of the flower delivery uk bouquets usually consists of two parts, a contracted portion, often thread-like, termed the filament fig. 25 f, and a broader portion, usually of two lobes, termed the anther a, containing the powdery pollen p, and supported upon the end of the portion of the filament in contact with the anther-lobes is termed the the FIG.

Young stamen is abortive, flower in which the stigma N is receptive and cannot perform and the stamens 3 have not yet opened; its II. 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, flower delivery uk bouquets in Butomus umbellatus; or clavate, that is, narrow below and broad above, as in Thalictrum. In some instances, as flower delivery uk bouquets 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 usually 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 bent or jointed, becoming geniculate; at other times, as in the pellitory, it is is colourless, or of different in fuchsia and Poinciana, it flower delivery uk bouquets red; in Adamia and Tradescantia virginica, blue; in Flower delivery uk bouquets 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 are continuous with the torus, and the stamens flower delivery uk bouquets persistent, although in a withered are produced in the whorl of stamens 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 flowers delivery dunstable central bundle when the pistil is abortive, the stamens becoming monadelphous, as occurs in plants of the Mallow tribe; or they may be arranged in two bundles, flower delivery uk bouquets stamens being diadelphous, as in Polygala, Fumaria and Pea; in this 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, Flower delivery uk bouquets, and Aristolochiaceae fig.

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 anther - the outer, or exothecium, resembles the epidermis,and often presents stomata and projections of different kinds fig.
