Palm oil trees

I am trying to figure out if there are "heirloom palm oil trees" and what they are. I live in sacramento and alot of things that should grow well here grow ok depending on were you put them in the garden and what with. So im wondering could i get away with a palm oil tree or two.

Tokunbo, we need one of our tropical members to find this. I know nothing about oil palms!
wikipedia has generic info on traditional species.
I added the thread to the Africa and Asia forums.

Check around in Southern California. Many of the streets in Los Angeles are landscaped with palm trees that drop fruit that look suspiciously like oil palm fruits. As far as being "heirloom" I wasn't aware that much selective breeding had been done with oil palms, so just about any wild tree that you find will probably be "heirloom".
