What you need:
Here are two shots of the same pollen, one under low power (left) and one under high power (below). You need to adjust the focus up and down if you want to see the distinctive patterning (called sculpting) on the surface.
The pollen is from a pea, Gompholobium, which was quite infamous in the early days of Australian settlement, because it poisoned sheep which ate it. The poison, sodium fluoroacetate, is used today under the trade name "1080" (ten-eighty) to get rid of pests, because Australia's marsupials are able to resist the poison which is good against rabbits and foxes.
