RE crypts

I'm sure Richard will chime in on this one! First off good job! Get a
picture ASAP too!

Go to Jan's Crypts pages for a better ID and pic's.

Got you interested in making seeds eh? I doubt they will ever fertilize
submersed. The old Phosphorus flowering trick can sometimes trigger it and
*perhaps* so can high levels of Ca and/or Mg with the cordata. It may be
something else besides cordata but check the Crypt pages to be sure. Good
vigorous health is the best for flowering IMO. Yellow limb sounds like it.
I'd kill to get some Rosefolia cordata though!
Often the "kettle" is shown. This does not open but is cut to show the the
parts. Submersed crypts do "open" but there is a long tube going down to the
flower making them seem closed but there is a small opening at the top to
let the little bugs for pollenation in and out. 
This may help. I have a pic of a C. cordata var blassii flower submersed
that may be in TFH soon so get that pic also! We need more crypt keepers in
the USA. My C. lingua seeds are fertile and growing now. Fun stuff.
