Species iris distribution in No. America - the list

For those of you interested in finding native iris near you, here is a
listing, by state/province, of the iris species found in North
America.  It is based on a list by Roy Davidson in SIGNA (the species
iris group newsletter) No .7 April 1971.  I have updated it based on
information from several sources including Iris-l discussions. 
Comments and corrections are welcome.  (Would one of you webmasters
out there host a graphic from of this if I produce the pages?)
