Etymologies

Sorry, no etymologies found.

Examples

  • By the peculiar arrangement of the parts of the flower, the first bee which does so carries away the pollen-mass glued to his back, and then when he has his next involuntary bath in another flower, as he crawls out the pollen-mass attached to him comes in contact with the stigma of that second flower and fertilizes it.

    On the Genesis of Species

  • "This antenna transmits a vibration to a certain membrane, which is instantly ruptured; this sets free a spring by which the pollen-mass is shot forth like an arrow in the right direction, and adheres by its viscid extremity to the back of the bee!"

    On the Genesis of Species

  • Within these petals, at the upper part of the flower, there was the ordinary column, and at the opposite side, alternating with the petals before mentioned, two additional lip-like petals, one provided with a half-anther containing a single perfectly formed pollen-mass (A 2, A 3).

  • From this simple condition, which differs but little from that of a multitude of common flowers, there are endless gradations, —to species in which the pollen-mass terminates in a very short, free caudicle, —to others in which the caudicle becomes firmly attached to the viscid matter, with the sterile stigma itself much modified.

    VII. Miscellaneous Objections to the Theory of Natural Selection

  • This antenna, when touched, transmits a sensation or vibration to a certain membrane which is instantly ruptured; this sets free a spring by which the pollen-mass is shot forth, like an arrow, in the right direction, and adheres by its viscid extremity to the back of the bee.

    VI. Difficulties of the Theory. Special Difficulties of the Theory of Natural Selection

  • The pollen-mass of the male plant (for the sexes are separate in this orchid) is thus carried to the flower of the female plant where it is brought into contact with the stigma, which is viscid enough to break certain elastic threads, and retaining the pollen, fertilisation is effected.

    VI. Difficulties of the Theory. Special Difficulties of the Theory of Natural Selection

  • When the bee, thus provided, flies to another flower, or to the same flower a second time, and is pushed by its comrades into the bucket and then crawls out by the passage, the pollen-mass necessarily comes first into contact with the viscid stigma, and adheres to it, and the flower is fertilised.

    VI. Difficulties of the Theory. Special Difficulties of the Theory of Natural Selection

  • Dr. Crüger sent me a flower in spirits of wine, with a bee which he had killed before it had quite crawled out with a pollen-mass still fastened to its back.

    VI. Difficulties of the Theory. Special Difficulties of the Theory of Natural Selection

  • Attached to either side of the little horny piece is a flattened yellow pollen-mass, and so away he flies with a pair of these pollinia, that look like tiny saddle-bags, dangling from his feet.

  • The anther sacs tipped with a winged membrane; a waxy, pear-shaped pollen-mass in each sac connected with the stigma in pairs or fours by a dark gland, and suspended by a stalk like a pair of saddle-bags.
