Mount Hamiguitan
"Nepenthes micramphora" has no confirmed natural hybrids, although certain plants from Mount Hamiguitan may represent crosses involving it and "N. hamiguitanensis", "N. justinae" (previously identified as "N. mindanaoensis"), and "N. peltata". Plants that were originally thought to represent a natural hybrid between "N. micramphora" and "N. peltata" are now recognised as belonging to a distinct species of possible hybridogenic origin, "N. hamiguitanensis".
