For some time botanists have thought that the Sweet Potato in the
Pacific spread from South America in prehistoric times.

Are there any suspected cases of a reverse migration - that is plants
crossing from the old world, over the Pacific, to South America in
prehistoric times?

The Malva/Lavatera group is predominantly Mediterranean, extending to
Macaronesia, South Asia, Central Asia and northern Europe. There are two
disjunct elements - one species (Lavatera plebeia aka Malva australiana)
in Australia and a few species on islands off the Pacific coast of
California and Baja California. There are closely related to each other,
and to the widespread Eurasian Malva sylvestris. This may represent a
case of transpacific colonisation.

Pavonia hastata is present in South America and Australia (but is only
doubtfully native in Australia).

Perhaps Cordyline and other plants grown by the Polynesians.

Do you mean just plants transported by humans, or do you include
natural long-distance dispersal? Perhaps try coconuts, Cocos nucifera
as a likely [but not uncontroversial] example.

I was asking about 'recent' natural dispersal, since I didn't think
humans transported plants from the western Pacific to the New World
until European explorers came on the scene. Am I right on this? What's
the current story?

Haven't you done any research on this topic on your own?

Do a Google search on the pacific flora, Hawaiian plants and the Polynesians
and you will quickly find out otherwise.

Yes, of course I know about the Polynesians and plant dispersal.

But so what? To me the New World is the Americas.

Do a Google search on define:New World

Or are you suggesting that there is evidence that the Polynesians kept
going and reached the Americas?

That was (and probably is) the controversial question

Wrong way.

Heyerdahl's proposal was a migration of Polynesians from the Americas
west into the Pacific.
