Related Species
Nepenthes attenboroughii is closely related to the Palawan species, N. deaniana, N. leonardoi, N. mantalingajanensis, N. mira, and N. palawanensis (which produces even larger pitchers), to N. peltata from Mindanao, and to N. rajah from Borneo.
The stated relationship of this taxon with species from Borneo and Mindanao agrees with observations made in the description of N. mira, and is further supported in the type description of N. attenboroughii by previously overlooked paleogeographical evidence. Based on this evidence, the authors reason that these species, predominantly found growing on ultramafic soils on Palawan and Mindanao, are likely to have arisen as a result of the radiative speciation of a common ancestor in Borneo.

“A parent who from his own childhood experience is convinced of the value of fairy tales will have no difficulty in answering his child’s questions; but an adult who thinks these tales are only a bunch of lies had better not try telling them; he won’t be able to related them in a way which would enrich the child’s life.”
—Bruno Bettelheim (20th century)
“Prostitution is the most hideous of the afflictions produced by the unequal distribution of the world’s goods; this infamy stigmatizes the human species and bears witness against the social organization far more than does crime.”
—Flora Tristan (1803–1844)
