1. Close to N. meduseum and N. macro-phyllum, both from Borneo, and to N. melliferum, mainly from continental Asia.
2. Since King (l.c.) the present species has been confused with N. hamulatum, mainly because the collections Goodenough 1352 and Scortechini 1992, both N. hamulatum, have wrongly been identified with this species. Therefore, notes on the timber published without any reference to collection numbers are untrustworthy and have been omitted.
