Nepenthes boschiana (/nɪˈpɛnθiːz ˌbɒʃiˈɑːnə/; after Johannes van den Bosch), or Bosch's pitcher-plant,[3] is a tropical pitcher plant endemic to Borneo.

[4] Nepenthes boschiana belongs to the loosely defined "N. maxima complex", which also includes, among other species, N. chaniana, N. epiphytica, N. eymae, N. faizaliana, N. fusca, N. klossii, N. maxima, N. platychila, N. stenophylla, and N. vogelii.

[6] The species was formally described by Pieter Willem Korthals in his 1839 monograph, "Over het geslacht Nepenthes".

[2] B. H. Danser, in his 1928 monograph "The Nepenthaceae of the Netherlands Indies", wrote the following:[3][7] Korthals states the natives who accompanied him on Mt.

Sakoembang gathered the not yet opened pitchers, as the water which they contained was a medicament against inflammation of the eyes, whereas others cut the opened pitchers as playthings for their children.
