I posted a topic in regards to identifying this Nepenthes as the species 'Khasiana' or a hybrid with mirbailis last year at some point. The previous thread can be found at this link:
PREVIOUS THREAD ABOUT KHASIANA
It appears as summer draws closer the size of pitchers increase in size as represented in some of the photos below.
Also at the onset of spring, the pitchers in spring are different to those in summer.
Taken WITH flash. Same plant. The pitcher on the left is from last years summer. The pitcher on the right is from early spring this year.
Taken WITHOUT flash. Same plant. The pitcher on the left is from last years summer. The pitcher on the right is from early spring this year.
This was a photo of pitchers taken side by side from the same plant but produced in a different season. I understand pitchers are polymorphic. However, I find this odd that it produces pitchers in Spring as on the right and pitchers in summer as on the left. Quite a difference in peristome, lid, etc...
