This wiki page is a collection of example [[Introduction to L-system trees|L-system trees]]. The intention is to help newbies better understand L-system trees, but also to provide usable tree definitions which could be used in mods.

If you wish to add a tree, please use the template at [[/Template]] and insert the filled-out template into this wiki page. Don't forget to [[Special:Upload|upload]] a screenshot as well.
