Hi ya' Graham! 
To quote 2001: A Space Odyssey: "My God! It's full of stars!"
WOW! These are neat! I have yet to begun to explore plants with my microscope. I had no idea that plant structures respond to polarized light. This is one more thing to add to my "to do" list. Thanks for sharing this, Graham.
Best regards as always, my friend.

Tom,
Lignified tissue is bright in polarised light, as are things like starch grains, calcium oxalate crystals etc., so it is a useful technique for looking at plant structures.
