I would like to add a bit to this message. One of the things 
that bothers me about the occurence of I hookeri (= setosa var
canadensis) on the east coast of N America is how did it get there
from the west coast? Did it originally occur on the entire north
coast of an earlier N American continent and spread down the east
coast to Maine and the Canadian maritime Provinces? I would really
like to know. Anybody have enough geology to offer clues?
