How about Professor Hemlock, 

for a list of tree names go to: http://www.ces.ncsu.edu/depts/hort/consumer/factsheets/trees-new/common_namesa_e.html

Also if it helps with your game development some one else on DS Game Maker Forum - (http://www.dsgamemaker.com/forum/viewtopic.php?f=56&t=5846) said the following:


Yeah, simple - do it just like the creators of pokemon;

1.Go to File > New Game
2.Type the name of your game (whatever you like) followed by "_GAMETYPE_POKEMON", be careful not to include the quote marks
3.Press enter

Voila! There you have it! You're very own adventure is about to unfold! DS Game Maker creates the whole thing from scratch, compiles to .nds files, and ships to all major toy stores near you. It's never been simpler - make your own pokemon adventure today!

Hope this helps!
