It does look similar to my C.Pontederifolia.I have a ton of crypt wendtii, red and green, and it is definitely not that. It doesn't have a bulb either.
What about crypt pontederiifolia?
Here's a curve ball. This part of the filter (it's smooth plastic) wasn't submerged until recently, and the riccia actually climbed out of the water to latch onto it. . .
