C. keei?

This was the 2nd location where we found cryptocorynes during our field trip to west Kalimantan. The stream has a sandy base with stones and the pH is about 6.5.

We found a spathe which I felt looked like that of C. keei. However, when we spliced open the kettle, again no female flower was present at all?!?!? My explorer friend referred to it as C. sp. 'West Kalimantan 2' in his blog. I will leave it to you to decide for yourselves what species this is.
