Pollen, or Farina fecundans, denotes the fertilizing powder, found in the anthers, or tops of the stamina of plants; and which, when sufficiently mature, is conveyed to the pistils for the purpose of f cundation.
The farina is, in general, of a yellow colour ; it is very conspicuous in the tops of young or unripe flowers, and especially in those of lilies and tulips. It consists of minute hard particles, covered with one, two, or three elastic membranes, bursting and shedding the flower dust to a considerable distance, as soon as it has arrived at maturity.—When viewed through the medium of a microscope, they usually present a particular form, that is observable throughout the genera of an order, as well as all the species of a genus of plants.
Naturalists have discovered, that the pollen contains a waxy, unctuous matter, and is colle6ted in the hairs with which the thighs of bees are covered. These insects triturate, and otherwise prepare it in their stomachs, whence it is ejected in a concrete form, under the name of Wax.
