I would suggest using the USDA PLANTS database
(http://plants.usda.gov/) and do a generic search of northeastern
Orchidaceae. I just did a quick search and found 125 genera for the
U.S. I created the following list of genera in the northeast, which I
believe is complete. Hopefully someone else from our group can
add/correct if I am wrong. Anyway, go down the 125 genera and click on
the genera I have identified (I included 1 non-native, just to be
complete!). You will see a 'related taxa' section about mid-way down
the page that shows range maps. If you figure out the answer to your
question, please share your results!

Aplectrum
Arethusa
Calopogon
Calypso
Cleistes
Corallorhiza
Cypripedium
Epipactis (non-native)
Goodyera
Habenaria
Isotria
Liparis
Listera
Malaxis
Orchis
Pogonia
Polygala
Spiranthes

Best of luck!
