Cryptocoryne balansae is treated today as a variety of Cryptocoryne crispatula, called C. crispatula var. balansae. As far as I know, at the moment the botanists distinguish 7 varieties of C. crispatula: http://crypts.home.xs4all.nl/Cryptoc.../alphabet.html
But apparently there are also forms or populations of C. crispatula not well fitting in any of the described varieties.
I mean, the inflorescence of Your Crypt points to Cryptocoryne crispatula, compare with these photos: http://crypts.home.xs4all.nl/Cryptoc...y/cri/cri.html
But I agree, it's not the var. balansae.
Cryptocoryne albida is very close to C. crispatula, apparently some plants have very similar inflorescences: http://crypts.home.xs4all.nl/Cryptoc...y/abi/abi.html
