    • n pollen A fine yellowish dust or powder produced in the anther of a flower (whence it is discharged when mature), which when magnified is found to consist of separate grains of definite size and shape; the male or fecundating element in flowering plants: the homologue of the microspore in cryptogams. The individual grains are usually single-celled and of a globular or oval form, but they may occasionally be composed of two or several cells, curiously irregular in shape. They are often beautifully ornamented with spines, angles, lines, etc., and while they are very uniform in the same species they often differ widely in different species or families. Pollengrains are usually formed in fours by the division of the contents of mother cells into two parts and these again into two parts. Each grain has two coats, the inner of which is called the intine and the outer the extine. See pollen-tube.

In shadow half, half in the moonbeams' glower,
Lifts slowly there.

The centre of the speedwell gleams; so fair,
So mystic-frail the tremulous pollen-worlds,
Divinity itself seems slumbering there.

As she flitted by garth and slipped through glade,
Her light limbs winnowed the wind, and made
The gold of the pollened palm to float
On her budding bosom and dimpled throat.

See, sweetheart, how the lilies lay
Their lambent leaves about our way;
Or, pollen-dusty, nod and float
Their moon-like flowers around our boat.--
The middle of the stream we've reached
Three strokes from where our boat was beached.

In science:

It is accepted that the random walk of each pollen is a result of a random “kick” that comes from the solvent. It is assumed that the “kicks” are result of the action of random “sources” that originate from the discrete atomic structure of the solvent.
Fluctuations and Long-Term Stability: from Coherence to Chaos
Then the random walk of each pollen is successfully described by adding stochastic force to the deterministic friction in the equation of motion so that the stochastic force to match the behavior of the random “kicks”.
Fluctuations and Long-Term Stability: from Coherence to Chaos
Further, the transition from the Langvin to Einstein-Smoluhowsky equation for the diffusion on coarse-grained time scale demands well-defined concentration of the pollen species.
Fluctuations and Long-Term Stability: from Coherence to Chaos
On the other hand, since the size of the pollen is much larger than the size of the solvent molecules, it is obvious that the “sources” must be spatially extended.

Another example of random motion in classical physics is provided by the Brownian motion of pollen grains in a fluid.
Hidden Variables, Non Contextuality and Einstein-Locality in Quantum Mechanics
We know here that the randomness of the motion of pollen grains is due to their being constantly buffeted by the large number of molecules of the fluid.
Hidden Variables, Non Contextuality and Einstein-Locality in Quantum Mechanics
The molecules of the fluid remain hidden to our view under the microscope used to observe pollen grain.
