Symbols and Markings

[Li'l Brudder]

So, Spore is rife with various symbols and markings to designate various things.  Mostly with planets and their types.  I'm having trouble figuring a single symbol out.  It's a planetary symbol that looks like a maple leaf or something.  There's a paw for creature stage, a campfire for tribal, a UN-esque symbol for civ, and a rocket for Space.  I assume it means cell, but then again, why designate that if you can't interact with cell-level creatures?

Also, this really didn't fit in anywhere else and this is a shiny new forum.

Leaf planets are "wild planets." They're T1 planets with plants only. They're easy to terraform, and you can steal the plants if you want to. That's about it.

I think "wild planets" are only the ones with animals. But, what kutto said: it is a planet with plants, but no animals. Yay!

Clarification: Leaf planets are planets with a T1 or better rating and no animals. There do not actually have to be plants on it, the leaf symbol will appear even if the planet lacks plants.
