INDIAN PIPES
The CT Botanical Society says the Indian pipes are related to pinesap (which is a very pretty flower).

Tom Volk’s on-line column says Indian pipes is a flowering plant in the blueberry family.

and
Keith Dawson says “It's a flowering plant related to the dogwood, evergreen laurel, and rhododendron.”

When I started the search for authorities on Indian Pipes, I didn’t think I would find 3 diverse descriptions. So I tried another site.
Web of Species, Biodiversity at Wellesley College and in New England produced a few more nicknames but no relationship to other plants. http://www.wellesley.edu/Biology/Web/Species/pindianpipe.html
and, last but not least,
WikipediA
http://en.wikipedia.org/wiki/Monotropa_uniflora
All the above web sites have much prettier pictures than I have, so by all means check them out.
PIPSISSAWA
I couldn’t find any web sites with pictures so you will have to contend with the one I have posted. It seems Pipsissawa is an herbal, medical remedy for certain bladder problems. I will not list websites here because there is no way I want to give out alleged medical advice. If you, the reader, wish to pursue this you are on your own.
