Do you mean something on the order of "white spots"?

Not really, just highly reflective. Some can be seen in this picture

They are specular, the appearance depends on the direction of the
light.


Ah, as a flower photographer I am quite familiar with those. They are
just epithelial cells, when they are turgid, they stick out from the
surface slightly, and make a little lens like structure. If the surface
is shiny, you get that effect. There is probably some specific term for
that effect, but my Stearns is in storage, and I can't think of
anything right now, although rugulose comes close as a description.

Oh, and I meant to say thanks for the response.
