Don't know about shell pink flowers on nelumbiifolia but it sounds intriguing. A picture would be helpful. How big were the leaves? Was there distinctive veining in the leaf?

B. hernandioides has pink flowers but would look like a small nelumbiifolia without distinct veins for example.

Like a dummy I didn't take a pic. I'd say the leaves were about 6 inches across on average. My memory is the leaves were fairly smooth, like a lily pad, and very distinctively round (pretty sure it's not B. hernandioides due to this roundness). The flowers were on a tall stalk fluttering above the leaves. Overall the whole plant was about 2 feet across. It may have been a young plant. He's trying to air layer to increase his plants so I'm going to call in a few weeks to see how that's going. I WANT THAT PLANT. :D

If you get a picture please post it.

I do plan on going back and will get a pic then and repost. I had my camera and everything that day. :X
