Bees will act like a camel-hair pencil, and it is quite sufficient just to touch the anthers of one flower and then the stigma of another with the same brush to ensure fertilisation; but it must not be supposed that bees would thus produce a multitude of hybrids between distinct species; for if you bring on the same brush a plant's own pollen and pollen from another species, the former will have such a prepotent effect, that it will invariably and completely destroy, as has been shown by Gärtner, any influence from the foreign pollen.
Flowers terminal, just peeping above the tubercles; sepals and petals acute, yellow, ¾ in. long; anthers yellow; stigma white. An old garden plant, introduced from Mexico. It flowers in May and June. For its cultivation it may be treated as recommended for M. pusilla.
Flowers terminal, erect, with several whorls of spreading, recurved petals, the lower ones tinged with crimson, the upper pale yellow, and forming a shallow cup, 2 in. across; anthers forming a compact sheaf in the centre. Flowers in summer. This distinct and very pretty species was introduced many years ago from Mexico, where it was discovered in 1845 by a Mr.
The anther with its pollen is the important thing; so there may be useful stamens with no filaments, but never useful stamens with no anthers. The amount of pollen in the flowers is always astonishing and interesting. Why should there be so much? That the bee gathers honey from the blossoms is one of the earliest things the child learns.
O. biennis and O. muricata have their stigmas in immediate contact with the anthers within the flower-buds, and as the anthers open in the morning preceding the evening of the display of the petals, fecundation is usually accomplished before the insects are let in. But in O. lamarckiana no such self-fertilization takes place.
Dorothy walked immediately behind Helen. She was dressed like a garden lily, her petals wired so that they turned out and up at the tips. She wore yellow stockings and slippers as a reminder of the anthers or pollen boxes on the ends of the stamens of the lilies. Dicky's costume created as much sensation as Roger's. He was a Jack-in-the-Pulpit.
Here and there from this green ground rose pure white stars edged with a line of gold, and from their throats came crimson anthers but no pistils.
On the belief that this is a law of nature, we can, I think, understand several large classes of facts, such as the following, which on any other view are inexplicable. Every hybridizer knows how unfavourable exposure to wet is to the fertilisation of a flower, yet what a multitude of flowers have their anthers and stigmas fully exposed to the weather!
The change of stamens into petals is a gradual modification. All intermediate steps are easily to be found. In some flowers all stamens may be enlarged, in others only part of them. Often the broadened filaments bear one or two fertile anthers. The fertility is no doubt diminished, but not wholly destroyed.
Rudiments of two hinder wings are seen in the class Diptera, or two-winged insects Teats of male animals Filaments without anthers in Curcuma, Linum, &c. and styles without stigmas in many plants, shew the advance of the works of nature towards greater perfection Double flowers, or vegetable monsters, how produced The calyx and lower series of petals not changed in double flowers
