A Vanadinite crystal in R-DIC

Back in February of this year I posted two images of vanadinite crystals. The subject of this post is in the top image of that post.

Hi Ken. It is good to see that you are still enjoying myxomycetes. I know you have worked with them for well over a decade now. I look forward to more of them myself. Walt

Thank you so much Leonard, Pau, Sumguy and Jacek. Leonard, if I may ask what is it about image 3 and 4 that interest you? Pau, I used direct oil dipping for the UO 75x objective. Per Leitz, a cover slip is not required. Enjoy your future observations. Walt

Hello Sumguy, Roel and Gary. Thanks for showing your interest. Welcome Roel and thank you for adding to my post. I didn't think about these tracheary elements extending all the way into the fruit of a plant, but then how else would bananas be so juicy! I will have to try polarized light the next tim...
