Bruce seems to have nailed it on the head. Regardless of status as cultivar, or named hybrid, we're looking to protect Sarracenia. There are cases where species/hybrids are being removed from bogs for maintenance purposes.
A good example is the Watson Pineland Preserve that our Head Grower Mike Howlette does work with. At some point, someone decided that it would look nice to add some diversity to the all S. alata stand by adding some S. leucophylla. Today, the S. x areolata (the hybrid between the two species) are being removed. They're lovely plants, sure, but if we were doing a rescue in an area where something like this had happened, the original natives of the area would be the top priority.
To sum up: We are looking to protect all endangered Sarracenia, that is, regardless of cultivar or hybrid status, so long as they're native to the population.
