No idea what these are. I can see what look like spores, but I suspect they are contaminants.

Hi Adam
the plant is an Elaeagnus, and what you are seeing are the "trichomes", in this instance effectively peltate hairs, which give the leaf its silvery appearance (and help it survive periods of drought).

PS I seem to remember, when I was bought my first microscope (one step up from a toy one) well over half a century ago it came with a prepared slide, and it looked suspiciously like these . . . .
