Map Packs (wastelands and palm trees)

[The Real Glyph]

Are there any SW artpacks that cover palm trees and deserts/wastelands? Also, interested in anything for roman, greek, babylonian etc buildings (inc ruined ones) - Thus far I've only found deciduous & pine trees, and two options for columns

I'm always interested in this as well. I really like Gabriel Pickard's stuff, you can find it on DriveThruRPG.
