if you have access to the software, go to http://www.3dcafe.com and download a palmtree 3D Mesh, I know there is one there because I did so my self.
then either render it out, import into flash and trace over. or render using the Illustrate 5.0 plugin for max which will export in swf format.

good luck

cheers
