3 Several tiny, slenderly built specimens (including some with immature male flowers and inflorescences with comparatively long peduncles) now inserted under M. iners, link up with M. fallax; this should be given attention during future investigations. 1 Myristica fallax is a satellite species of the variable M. iners and comes close to the type of M. vordermannii, which goes as a delicate form under M. iners. Myristica fallax is distinguishable by its slender twigs and small, thin, membranous, dark-coloured leaves. Infructescences are long with a slender peduncle, fruits are small, 3.5-4 cm, and early glabrescent. Specimens of M. fallax are reminiscent of M.fragrans. 2 I have not seen the type of M. fallax, Beccari 1590 (Sarawak, Mt Mattang) in FI; the description of the male inflorescences and flowers above is based on Warburg (I.e.).
