The six stamens are in two, equal sets, the filaments of each set somewhat united, the middle anther of each set with two cells, the others with only one.
Adnate, [Illustration] anther attached by its whole length to filament.
Remove the anther from the lily and the flower will not fade so soon by several hours.
They bear gifts of quickening pollen from other plants, or swing the anther censers that waited the coming of expected guests.
Various kinds of pollen grains were tested, and as a rule, pollen was only taken from one anther in each experiment, though occasionally it was from several anthers of the same flower.
I suppose you were afraid I was going to give you anther whistle.
You'll have to hand up a chair, boys, because I'm never going to get shet of this goldarned speech any anther way.
Surrounding the pistil are the stamens, few or many, the antherat the extremity containing the powdery pollen.
His forward movement thus far to this point has only seemed to press the edge of the anther inward, and thus keep it even more effectually closed.
The lip of the anther catches upon the back, swings outward on its hinge, and deposits its sticky pollen all over the insect's back, returning to its original position after his departure.
These are the conditions expressed; and how admirably they are fulfilled we may observe when we examine flower after flower of a group, and find their nectaries drained, their anther cells empty, and pollen upon all their stigmas.
The pollen is also quite different in its character, being here in the form of a pasty mass, whose entire exposed surface, as the anther opens, is coated with a very viscid gluten.
Concealed within, against the ridge-pole, as it were, the anther awaits his coming, and in his passage to and from the nectar below spreads its pollen over his head and back.
Illustration] The anthers in this genus, then, are two, instead of the previous single anther with its two pollen-cells.
The insect must have a tongue of such a length that, when in the act of sipping, its head must pass beyond the anther well into the opening of the flower.
Every one is familiar with the curious construction of this flower, with its ten radiating stamens, each with its anther snugly tucked away in a pouch at the rim of its saucer-shaped corolla.
As the insect works its way beneath the viscid contact, the anther is seen to be drawn outward upon its hinge, and its yellow contents are spread upon the insect's back (Fig.
A) the column inclines forward, bringing the anther low down, and its base directly opposite the V-shaped orifice in the lip, which also is quite firmly closed beneath the equally converging upper hood of the blossom.
This anther lid is closed tightly, with the sticky mass of pollen hidden behind it in the cavity.
Although it is generally admitted that the filament of the stamen corresponds to the stalk of the leaf, and the anther to the leaf-blade, yet there are some points on which uncertainty still rests.
Now, in this case, the margins of the anther were coherent to form the cup, and the pollen was emitted along a line separating the polliniferous from the petaloid portion of the anther.
The bearings of these and other similar malformations on the morphology of the anther are alluded to under the head of petalody of the anther.
The main points of morphological interest relating to the androecium, referred to in this volume, are those concerning the structure of the anther (see p.
Bischoff's notion as to the sutures of the antheris correct, viz.
In the malformed flowers no pollen is formed, at least in the more complete states of the malformation, but the walls of the anther lobe become preternaturally enlarged, and petaloid in texture and appearance.
The same observer also records the presence of a secondanther between the lobes of the normal one.
A similar change in the anther and connective takes place more frequently in flowers where the number of stamens is smaller, but there are of course numerous exceptions to this rule.
Furthermore, the essential thing about the anther is the pollen, to manufacture which is the sole purpose of the stamen.
This is the common method for opening the anther sacs, but in some flowers it is curiously modified.
When the anther is ripe these pouches are filled with a yellow, powdery dust called the pollen.
The anther pouches are therefore full of pollen-grains.
Of the two parts of the stamen, the filament and anther, the latter is the essential one, so that in some cases the filament may be lacking entirely, only the anther appearing to represent the stamen.
The pollen is necessary to enable the flower to produce seeds, but it must be transferred from the anther which produces it to the fourth part of the flower, not yet described, in which the seeds are formed.
As an anther producing a single grain of pollen is not inconsistent with our notions of structure, so neither is an anther consisting of a single grain of pollen.
How is it explained that in some transformations of this, the anthers alone are petaliformed, while in others both filament and anther are equally and primarily affected.
The former are in clusters of about three or four, in a cuplike, fleshy bract, each flower having four thick, triangular petals with an anther on the middle.
There are two stamens, each with a fertile and an abortive anther connected by a thin stalk which is fastened to the short filament in such a manner that it rocks.
Sometimes the stamen has no filament, and the antheris then said to be sessile.
The stamens, eight or ten in number, are usually rendered peculiar by the tubular bristles that extend upwards from the anther cells.
That part of an anther which connects its thec\'91, lobes, or cells.
Cells of the anther nearly parallel, the valves of each extended at base so as to form the sides of a deep oblong groove or cavity, which is lined by the dilated orbicular and incurved gland.
Flowers dioecious or monoecious, axillary, solitary and sessile; the sterile consisting of a single stamen enclosed in a little membranous spathe; anther at first nearly sessile, the filament at length elongated.
Anther cells oblong-linear, unequal, the outer fixed by the middle, the inner pendulous.
Cells of the anther parallel and approximate, their glands therefore contiguous.
Stamens 12, with more or less distinct filaments, their tips usually continued beyond the anther into a point.
As a leaf may be without a stalk, so the anther may be Sessile, or without a filament.
Extrorse, turned outwards; the anther is extrorse when fastened to the filament on the side next the pistil, and opening on the outer side, 101.
Deflorate, past the flowering state, as an anther after it has discharged its pollen.
The blade of a leaf consists of two similar sides; so the anther consists of two LOBES or CELLS, one answering to the left, the other to the right, side of the blade.
The Filament= is a kind of stalk to the anther, commonly slender or thread-like: it is to the anther nearly what the petiole is to the blade of a leaf.
Inane, empty, said of ananther which produces no pollen, &c.
Stamen of Moonseed, with anther cut across; this 4-celled, or rather 4-locellate.
Antheridium (plural antheridia), the organ in Cryptogams which answers to the antherof Flowering Plants, 150.
Stamen of Mallow; the anthersupposed to answer to that of Fig.
The anther is adnate when fixed by its whole length to the filament or its prolongation, 101.
The splitting open of an anther for the discharge of its pollen is termed its Dehiscence.
A simple conception of the morphological relation of an antherto a leaf is given in Fig.

Filaments club-shape, approximately as wide as theanther =Meadow Rue, Thalictrum polygamum.
The (usually) slender basal portion of a stamen, supporting the anther at its tip.
Portion of wall of anther of Wallflower (Cheiranthus).
The anther entire (a) with its filament; section of anther (b) showing the four loculi.
That part of the anther to which the filament is attached is the back, the opposite being the face.
The walls of the cells are frequently absorbed, so that when the anther attains maturity the fibres are alone left, and these by their elasticity assist in discharging the pollen.
The anther is developed before the filament, and when the latter is not produced, the anther is sessile, as in the mistletoe.
If theanther is absent the stamen is abortive, and cannot perform its functions.
Stamen, consisting of a filament (stalk) f and an anther a, containing the pollen p, which is discharged through slits in the two lobes of the anther.
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.
The division between the lobes is marked on the face of the anther by a groove or furrow, and there is usually on the face a suture, indicating the line of dehiscence.
Sometimes, however, only two cavities remain in the anther, by union of the sacs in each lobe, in which case the anther is said to be bilocular or dithecal.
The endothecium varies in thickness, generally becoming thinner towards the part where the anther opens, and there disappears entirely.
Quadrilocular or tetrathecal anther of the flowering Rush (Butomus umbellatus).
Pollination will be effected only when some of the pollen from a low-placed anther reaches the stigma of a short-styled flower, or when the pollen from a high anther is placed upon a long-styled pistil.
To understand this process of reproduction in flowers, we must first study carefully pollen grains from the anther of some growing flower.
In a single stamen the boxlike part at the end is the anther; the stalk which holds the anther is called the filament.
By pollination we mean the transfer of pollen from an anther to the stigma of a flower.
The anther is in reality a hollow box which produces a large number of little grains called pollen.
The weight of the visiting insect on the corolla releases the anther from the pocket in which it rests so that it springs up, dusting the body of the visitor with pollen.
This last species has only one stamen; but as the anther is four-celled, it is probably two stamens grown together.
The stamens have the filaments (b) curiously dilated at the base; and the point of each cell of the anther is cut into two erect awns (c).
The stamens themselves are as remarkable as the other parts of the flower; the filaments grow together into a thin kind of leaf, and each anther has but one cell, and opens by a pore at the apex.
The flowers are male and female; the first consist of four sepals, two of which are much longer than the others, and a beard of anthers, with the filaments united into one common stalk, and each anther containing two cells for pollen.
This rib is the anther; and the broader part is the dilated filament, which is drawn out beyond it, on both sides, and above, so as to form the brown tip above the anther already mentioned.
In this column there is one perfect anther (b), and two imperfect ones (c c).
You know the membranous cup or clinandrum, in many orchids, behind the stigma and rostellum: it is formed of a membrane which unites the filament of the normal dorsal anther with the edges of the pistil.
The inner whorl of anther ducts are oftenest aborted.
Cruger believed the viscid matter reaching the anther was a necessary condition for the germination of the pollen-grains.
Mr. Bailey describes how in Heterocentron roseum, "upon pressing the bellows-like anther with a blunt pencil, the pollen was ejected to a full inch in distance.
In Gymnadenia tridentata, according to Asa Gray, the anther opens in the bud, and the pollen being somewhat coherent falls on the stigma and on the rostellum which latter is penetrated by the pollen-tubes.
Yet how closely analogous to Campanula brushing pollen out of the anther and retaining it on hairs till the stigma is ready.
Knowing only two or three species in the genus, I had often marvelled how one cell of the anther could have been transformed into the moveable plate or spoon; and how well you show the gradations.
If bees visit the Rhexia, for Heaven's sake watch exactly how the anther and stigma strike them, both in old and young flowers, and give me a sketch.
It would, however, greatly add to the value if you were to cover up any of the forms having pistil and anther of the same height, and prove that they were fully self-fertile.
The anther develops four sporangia (pollen sacs), the process being very similar to that in such pteridophytes as the club mosses.
The anther in the freshly opened flower has a smooth, red surface; but shortly after, the flower opens, splits along each side, and discharges the pollen spores.
A section across the anther shows it to be composed of four sporangia or pollen sacs attached to a common central axis ("connective") (Fig.
Each stamen has a slender filament (H, f) and a two-lobed anther (an.
We all know, or should know, that the anther in flowers secretes and releases the pollen.
At the left is an insect just alighting on a clump of the blossoms of the high-anther form indicated below it.
A newly opened flower has its stigma erected where the incoming bee must leave on its sticky surface the four minute orange-like grains carried from the anther of another flower on the hairy underside of her body.
Now, each anther is tucked away in one of the ten little pockets of the saucer-shaped blossom and the elastic filaments are strained upward like a bow.
The pollen-bearing organs of a flower, each stamen consisting of a filament (stem) and anther which contains the pollen.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "anther" in a variety of sentences. We hope that you will now be able to make sentences using this word. Other words: corona; flower; petal; pistil; receptacle; stamen; stigma; style
