A recent pitcher opened on N. 'Predator'. The peristome used to be solid maroon on all the older pitchers, now the color is starting to weaken and the 'teeth' are starting to become more pronounced.
This is an older pitcher from the same plant. As you can see much darker coloration and a less extreme peristome. My plant seems to be taking on more hamata genes as it progresses.
This is the newest pitcher, while the size 'approx 14 inches' appears to be staying constant, coloration and peristome changes are evident.
