Lately I have seen a popular exterior decking used. (Northern Calif.) I
believe it is called something like paduk from Australia? The contractors
call it ironwood. It is only 1x and it is rated for residential use at 24"
spans. It is very durable, strong and it has a nice appearance.

I recently saw use of what appeared to be one of these woods on a
residential deck, and for exterior stair treads. It appeared elegant. Also,
it felt good, but supports were much closer than you mention. My work for
the project however had nothing to do with these features.
I suggest that stiffness, not strength, is what realistically controls spans
of any deck planking. People do not like springy floors underfoot,
