I am currently reading Fred Dortort’s book, The Timber Press Guide to Succulent Plants of the World: A Comprehensive Reference to More than 2000 Species.
The book is filled with interesting information and loads of gorgeous images of plants. I was curious about hydathodes. The description from the book follows: their leaves are dotted with hydathodes, a kind of pore that enables wet-growing plants to expel water, but which dry-growing crassulas have reversed, turning them into water-absorbing organs.
I can visualize, but what do hydathodes really look like?
When I was editing photos for a previous post, I noticed what appeared to be pin pricks on the leaves of my new addition, a Crassula capitella Red Pagoda.

It is exciting to read something interesting and then to see an example of it in person.
