Argentina: Chardonnay, Torrontés, Semillon.

Chardonnay is grown in many of Argentina's wine regions north to south although most of it by far in the province of Mendoza. It's officially the number two white grape (after Torrontés), which isn't saying much: Argentina remains serious red wine country. Making a perhaps more familiar European comparison though, there's about the same amount of Chardonnay as in Chablis, but planted much higher up.

Argentina: Torrontés

A swift blast of Google-ing resulted in the discovery that "... three Torrontés varieties exist in Argentina," says Wikipedia (goes there, for the more curious among you); and these aren't genetically related to the Torrontés you find in Galicia, northwest Spain, as I'd assumed, but are apparently a crossing of Alexandrian Muscat and another variety (Mission or something else depending on which one). Ah ha, so that would account for the refreshing aromatic grapey / citrus peel Muscat-esque styling you often get from these fairly addictive dry whites (if you like that kind of thing); but you also find characters (and higher alcohol too) more akin to Viognier or Gewurztraminer even: more exotic, full-on and sometimes spicy-yellow flowery...
