I teach a bit of botany, to our first-year students. I really enjoy the subject & hopefully some of that rubs off :) Anyway, I’m always on the lookout for new images to use in my lectures, & tonight I came across this stunning photograph by Eckhard Völcker, who has very kindly given his permission for me to share the image with you.  

While it looks like a lovely piece of lace in contrasting colours, it’s actually a section through a willow shoot, stained with dyes that (for example) highlight the lignified tissues in xylem and the fibre caps on vascular bundles.

You can see more of these beautiful photos here, or visit Herr Völcker’s webpage for more of his work.

(Your turn, Grant!)
