1 Myristica pachyphylla is similar to M. arfakensis, both with characteristic scattered dots on the lower leaf surface. May also be confused with M. longipes. 2 A deviating specimen is BW13780 (Roster) (with fruits, in L broken off and lacking) from Wandammen Peninsula, at 920 m altitude. In the absence of fruits it keys out near M. pachyphylla or M. arfakensis and is characterized by: twigs slender, leaves narrow, 10 cm, long-acuminate, conspicuously greenish, dotted below, and peduncle of infructescence slender, 15-20 mm long. It may represent an as yet undescribed species, but more material is needed.
