Diagnostics:
The leaf wing of this species is well-developed compared to the two other species that can be found in Singapore, i.e., Nepenthes ampullaria and N. rafflesiana. The leaf blade itself is also much narrower. The pitcher itself is uniquely shaped; both upper and lower pitchers are slender, elongated, and have a slight pinched centre.
Interesting Facts:
This is the most common and widespread pitcher plant species in Singapore. The reason, as aptly explained by Chan et al. (1997), is due to fact that the Slender Pitcher Plant is tolerant of pollution and can grow in a diverse range of soil conditions.The lower pitcher of this plant is characterised by the hairy fringed wing. This portion is very much reduced in the upper pitcher, with no hairs on the fringed wing. Completely maroon-coloured pitchers can also be seen sometimes, but they are not as common as the green-coloured ones. Their sizes varies greatly, especially for those growing on regularly mowed lawns can be shorter than 1.5 cm in length!
