Thought it would be easy just to add a photo...there are a few different ones in the database though, so thought i'd better check first :)

Found growing in the wild in Ontario Canada.

So... I'm not exactly following this exchange. Arisaema atrorubens is just a synonym for Arisaema triphyllum, which is the accepted name (and the most commonly used) for the same plant. So it's Arisaema triphyllum.
:confused:

Quote from Connecticut Botanical Society site, "While some sources divide New England's Jack-in-the-pulpits into three species (Arisaema triphyllum, A. atrorubens, and A. stewardsonii), most modern authorities lump them all into A. triphyllum. "
http://www.ct-botanical-society.org/galleries/arisaematrip.h...

According to the USDA plant database (http://plants.usda.gov) there are four subspecies:
Arisaema triphyllum ssp. pusillum
Arisaema triphyllum ssp. quinatum
Arisaema triphyllum ssp. stewardsonii
Arisaema triphyllum ssp. triphyllum
