A young S. x catesbaei F2
An unknown leucophylla hybrid. *Probably with alata or rubra.
I think the crimp in the lip was caused by an aphid while the pitcher was developing.
S. leucophylla x (psittacina x rubra)
A young S. (oreophila x purpurea) x leucophylla
An unknown hybrid. *My guess is S. rubra gulfensis x catesbaei. *It had dark red flowers.
Last, but not least, an anthocyanin-free S. leucophylla x rubra jonesii.
