Some details to answer a few questions posed.
The Ceph. giant are from Wistuba. I have a few larger clumps that are starting to produce some more mature pitchers but they are still small compared to what they should be .. These are plants only about a year out of TC so I wouldn't expect much from them at this point. The great majority are still producing tiny little pitchers.
The Heliamphora picture is H. minor Chimanta Tepui.
