Thanks. It looks like that's what I've got. The picture matches, and so does
everything in the description except the part about the flowers only lasting
a day. The night-blooming part explains why the flowers never seemed to
look fully open.

Can you tell me more about this "zigzag cactus?" I think I may be
growing it
without knowing the name. My plant grows a lot like my orchid cactus and
the
bloom looks similar, but the cross-section of the leaf is flat rather
than
triangular. When new, the leaves look like the edges were cut with
pinking
shears, and the shape becomes more extreme as the leaf matures. Take a
look
at http://home.earthlink.net/~lyons7/images/plant.htm
I would like to know the proper name for it and any other information
you
might have.
Thanks.

Cryptocereus anthonyanus, Zigzag, Fishbone, or Ric-rac cactus.
Here's a page about it:
