Habitat Zones?

I'm not sure how botanists divide up the zones in the New 
World.  Zoologists (used to, anyway) distinguish between the Nearctic 
(north temperate) and Neotropical zones.  Since I started out expecting to 
be a zoologist, that's still how I think of things.

The Flora of North America seems to stop at the Mexico-USA border.

Where are all our experts when you need one?
