Brazilian cherry is an oily wood. I use it quite often for floors and stairways. Its gorgeous, hard and oily.
Eipea(sp*) and Jara are like woods, Very hard, oily and naturally preserved. They are all from south american rain forests.
I would not recommend any of them for cooking under food. Now for picnic tables and decking, can't beat it. Heavy as hell though. The jara and epea is too hard to even air nail, have to drill and screw(stainless steel screws).
