This wiki page is a collection of example 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 upload a screenshot as well.
