Sometimes, instead of developing into the form we should normally find, the organ develops into another form, as when a petal stands in the place of a stamen, or the pistil reverts to a leafy branch. This will be more fully treated under flowers. The study of the different forms in which an organ may appear is the study of morphology. Forms of Stems. Stems may grow in many ways.
Let me quote her words: "The child can learn the difference of the names, color, and forms of flowers as soon as it can learn anything. The next step would be to simple lessons in the different parts of a plant the vegetative organs of roots, stem, leaves, passing on to the reproductive organs in the flower calyx, corolla, stamen, and pistil.
She was thoroughly acquainted with the obstinacy which formed the stamen of Georgia's character, and very cautiously the maternal guidance must be given. She began by gravely regretting the familiar footing Mr. Vincent had acquired in her family, and urged upon Georgia and Helen the propriety of discouraging attentions that justified the world in joining their names. This had very little effect.
The petals are five, of a yellowish-white, surrounding five branches of stamina, each bunch containing about twelve, and each stamen having four antherae. The pointal is knobbed at top. When the stamina and petal fall, the empalement resembles a fungus, and nearly in shape a Scot's bonnet. The fruit is in its general appearance not unlike the bread-fruit, but larger, and its coat is rougher.
Dispersion of the dust in nettles and other plants Cedar and Cypress unperishable Anthoxanthum gives the fragrant scent to hay Viviparous plants: the Aphis is viviparous in summer, and oviparous in autumn Irritability of the stamen of the plants of the class Syngenesia, or Confederate males Some of the males in Lychnis, and other flowers arrive sooner at their maturity
And now look at the stamens and pistils. You see that nine of the ten stamens have their filaments united into a sheath around the pistil, but the tenth stamen has its filament free. These are very marked characters, are they not? And, strange to say, you will find them the same in the tree and in the vine.
This drawing together is produced by a small weal, which appears as a more or less complete pollen sac, and in the same proportion the leaf approaches the simple form of a stamen. "The pistil in many cases looks almost like a stamen without anthers, and the relationship between the formation of the two is much closer than between the other parts.
She looked like a huge blue gentian kissed by the sun, for her top petticoat was of blue cotton, and her golden head seemed like the sweet-scented stamen. Andor thought that he could hear her voice above that of everyone else, and when Pater Bonifácius intoned the "Regina angelorum" he thought that indeed the heavenly Queen had no fairer subject up there than Elsa.
Usually, however, other leaves are present which are only indirectly concerned with the reproductive process, acting as protective organs for the sporophylls or forming an attractive envelope. The insect, &c., is attracted by the colour and scent of the flower, and frequently also by honey which is secreted in some part of the flower. Stamen and pollen.
The two that are left have a very strange shape, for the stalk or filament of the stamen is very short, while the anther, which is in most flowers two little bags stuck together, has here grown out into a long thread, with a little dust-bag at one end only.
