1465. In the truest sense is feminality co-ordinated with the digestive, the mascularity with the respiratory, system. The female is (organically considered) abdomen, the male, thorax. Pregnancy is a sexual process of digestion, impregnation a sexual process of respiration. In impregnation the female respires the male, whereby it receives into itself a thoracic function, becomes itself male, i. e. is then capable of producing something out of itself. Now, the female produces a fruit, which is synonymous with both principles. 1466. The semen is the fruit of the male. The male is always pregnant, and that indeed by virtue of his own power. This power is deficient in the female, which does not possess the light in itself, but only the elemental bodies that are ready and susceptible of form. 1467. The anthers are the male organs, the pollen is the semen. The pistils are the female organs, the seed-granules are properly speaking, the _germ_. 1468. The pollen is a most highly differenced, electrical product; the seed-granule a wholly indifferent, and tranquil mucous mass. The pollen falls upon the stigma of the pistil, and irradiation has taken place; the material fruit-capsule gains thereby so much polarity, that saps enough ascend, in order to develop the germless seed-vesicles. 1469. It is quite unnecessary for the pollen, with its sap or gas, to be materially conveyed through the style to the seed. It is only requisite for the style to be excited, dualized, electrified, and then it has life enough of its own. But it does not follow, because it is unnecessary for the sap of the floral dust or pollen to reach the seed-granules, that it cannot or ought not to reach thereunto. In many plants the pollen-tube does actually reach there and penetrate through the micropyle. In many styles it is still held as impossible, for the pollen-tube to penetrate through them to the seeds. The pollen-sap indeed simply evokes on the apex of the seed (upon the summit of the lorical rib, through whose liberation the micropyle originates) the vital process, which, without this stimulus, would perish. Thereby a new cell is secreted, from whence the germ is developed. IRRITABILITY--MOTION. 1470. In impregnation the heaven is married to the earth; for then the spirit descends, and does not esteem itself too highly to become flesh. Impregnation is the highest immaterial action of the plant.
