1268. The corolla obtains its last function in the production of the highest electrical bodies, which it exhales as sweet odours. Ætherial oils ascend out of the corolla into the air. 1269. The filament, as a leaf-rib that has become free, is a moribund ramuscular extremity, which still strives, according to the law of pinnation, to produce three buds, whereof, however, the terminal one is in general arrested, and the two lateral scarce attain unto apertion. 1270. The two lateral buds of the filaments are the _Anthers_. They mostly open in a spathose manner, because they have not strength enough to develop themselves as perfect gemmæ or buds. 1271. The anthers are to be regarded as follicles, which mostly rupture upon the dorsal or external aspect. 1272. The starch-flour, which forms the precipitate termed albumen in the seed, here obtains in the light-organ electrical properties, and is called _pollen_. 1273. The pollen has a light-function in the plant. 1274. The function of the pollen must be differencing, thus vivifying and secernent. 1275. The principal antagonism of the pollen is with the pistil, upon which it must therefore act in a properly differencing manner. The pollen does not hang, like the seed, by a stalk or pedicle to the wall of the anther, but is exudated from it like chemical bodies. It is nevertheless a vesicle, like all organic parts. This vesicle consists of two membranes, and contains yet smaller vesicles, which are called _fovilla_ or pollen-viscus. When the pollen comes into contact with the moist surface of the stigma, its external membrane ruptures, and the internal with its contained fovilla protruding in the form of a tube, penetrates the style in many instances down to the seed, whereby the germ first becomes developed or self-subsistent. 2. PISTIL OR OVARY. 1276. If the corolla be the light-flower, the stalk-flower is heat-flower. 1277. The stalk-flower, as being a repetition of the stem, must be developed later than the leaf-flower. It consequently stands superiorly upon, and so far within, this. The corolla is related to the stalk-flower like circumference to centre. 1278. The stalk repeated in the flower is the _Ovarium_, _germen_ or _pistillum_. It is frequently converted into wood in the nut and becomes hardened into stone. 1279. Nevertheless, the pistil like the corolla is a leaf-formation, because everything that originates subsequently to, can be none other than, the leaf. It is a leaf-bud under the idea of the stalk. The pistil is thus a leaf-whorl like the corolla, and one which is subject to the same fatalities, only with this difference, that its leaves are wont to open first after it has withered, and consequently through physical forces.
