I think the lid on faizaliana should be triangular. Even though theres not a good pic of them straight on or anything, I think the leaves look fusca sarawaky
This species is easily distinguished from most other Sarawak species by the very narrow triangular lid, though upper pitchers of the much rarer N. hurrelliana also have this characteristic. From the latter species its upper pitchers differ in having a more vertically-oriented mouth and a non-hooked glandular crest on the underside of the lid.
