They’ve got a good thing going down there.

New Zealand east side and Patagonian steppe

From what I´ve been reading this morning about the distribution of divaricating shrubs (yes, i did a double take too) in New Zealand vs Patagonia, the change in climate is somewhat similar due to the rainshadow created by the Southern Alps — and speaking of lichens in this area, I got so super excited… the Australasian Lichenology journal is free to download online – too cool!

The other side of the mountains is like New Zealand

Although I confess that I spent very little time on the rain-shadow side of south island New Zealand. Maybe the same thing happens there as on the eastern Patagonia steppe.

Same as central Texas?!

That´s super bizzarre — I´d think it´d be more similar to New Zealand or Australia…!!

Agreed, so odd Ramalina and Usneas next to soil crusts and uber arid land plants — they all taste so so so salty!

This flora reminds me most of central Texas(!)

All these Usnea, Ramalina, Teloschistes, parmelioids, as well soil crusts like Psora and Collema. It always seemed like an odd mixture of humidity-loving epiphytes and desert soil crusts. But here it is again. Weird.
