JMatt, I'm even more confused now. The single pitcher you have in your hand has a large rib for sure, but the ones in the first post dont look as large as the one in your hand. They look like regular ceph photos I've seen. But the first post is of your hummers whole plant right? A simple google search , http://images.google.com.sg/images?h...-8&sa=N&tab=wi showed cephalotuses with ribs of similar sizes. They look similar to a google search for hummers http://images.google.com.sg/images?h...s+hummer&gbv=2
Do you have a normal ceph? Maybe if I saw a photo containing the two.
