Upper pitchers are similar in most respects to their lower counterparts. They are broadly in the lower third and ovoid above, narrowing below the pitcher opening. They are also larger, reaching 21.1 cm in height and 9.4 cm in width. Wings are reduced to narrow ribs that run the whole length of the pitcher cup. The peristome is cylindrical and up to 4.4 cm wide. As in lower pitchers, it bears ribs up to 0.5 mm high and spaced up to 1 mm apart. The lid is up to 7.9 cm long and 5.6 cm wide. The spur, reported to be (with each branch being two-branched itself) and up to 16 mm long, is inserted near the base of the lid.
