Thanks, Bob!

I have read so often that the Caucasus is a diversity center and particularly the Caucasian writers always remember to mention Pterocarya, Zelkova etc. I wanted to know how the Caucasus really ranks in a global comparison. So I got the idea.

Appartently the Caucasus is some kind of diverstity center as it is included in the 21 diversity hotspots of the world.
The diversity may be greater in lower plants.
