Light on leaves

This is another of photos I took in Reiman Gardens, in their conservatory indoor green house. I like how the bright sun light, coming from behind the leaves, creates unusual effect. I believe these are “stained glass” begonias. I learned my lesson hard on names for plants (and animals as well). I did not take a notes or photos of labels, and now each time I am posting, I need an extensive research on Google :(.
