Nepenthes Merrilliana is a carnivorous plant from the family of pitcher plants plants (Nepenthaceae). It is native to the Philippines.

description

Nepenthes merrilliana is a creeping or climbing plant with obtuse-triangular shoots 7 to 10 mm thick. The internodes reach 1.5 to 7 cm in length. The leaves are scattered, linear, lanceolate and leathery in texture. They become 20 to 60 cm long and 5 to 7 cm wide. Their tips are rounded.

The pitchers show no pronounced dimorphism , lower and upper pitchers are similar to each other. The lower pitchers are broadly egg-shaped with a broadly rounded base, they are up to 35 cm high and 14 cm wide, their fringed wing strips are a maximum of 10 mm wide. The peristome is slightly sloping, 8 to 15 mm wide, flattened and clearly ribbed. The lid is broadly egg-shaped and 10 cm long and wide. The upper pitchers are broadly elliptical and up to 40 cm long and about 10 cm wide. This makes them one of the biggest pitcher plant traps . Instead of the wing strips, the upper pitchers have strongly protruding ribs. The peristome is flattened and rather broadly spreading. As with the lower pitchers, it has clear grooves. The lid is broadly ovoid and rather long than wide.

Male flowers are unknown. The female flowers are up to 20 centimeters long inflorescence axes in loose clusters, the flower stalks are little branched near the base, standing solitary towards the top. The 4 mm long bracts are lanceolate and tapering to a point.

distribution

Nepenthes merrilliana is native to Mindanao in the Philippines , where it colonizes tropical coastal forests on steep slopes at 20 to 1700 meters altitude.
