I see one petiole that doesn't seem to have formed much of a trap, plus a cup-trap type trap near the bottom of the pic.
These are one-time only "mutations" that happen on leaves of all geni now and again. These traits will not carry on through divisions, cuttings, seeds, etc, and will likely only happen once or twice in the life of the plant, assuming you don't live by a nuclear reactor
Here's another example of a single slightly mutated leaf, in this case on a drosera capensis:
the end of the leaf kind of curls backwards in two "fingers". So far, three leaves in a row have similar traits
Yes he did, the famous capensis 'crestate'. I bought a pot, but they reverted back to the normal capensis growth almost immediately, and continued to do so for almost a year before they died (I think).
The capensis pics shown above are of the normal clone.
