Leaves coriaceous, elliptic-oblong to oblong-lanceolate, 9-20(-25) by 3.5-6.5(-9) cm, more or less tapering to the ± blunt or acute apex, base rounded, sometimes subcordate or short-acute; Inflorescences of the Knema-typt; Fruits usually solitary, subsessile, ellipsoid(-obovoid), 2.5-3.5 by 1.5-2 cm, hairs dense, ru-fous-red, fine-woolly, 0.5-1 mm, longest towards the base of the fruit;


Asia-Tropical: Borneo present (Sabah present, Sarawak present); Sumatera (Sumatera present), NE, E, & SE Kalimantan present, Nunukan present, Riau present

1 Myristica beccarii resembles M. cinnamomea in foliage, but often the base of the blade is ± subcordate, and the petiole shorter; the fruits are smaller and the pericarp much thinner. Myristica beccarii also closely resembles M. smythiesii, but that species has more coriaceous leaves, more distinct nerves, and stouter twigs. Both M. smythiesii and M. beccarii have Knema-type inflorescences. The indumentum of the fruits is coarser than that of both M. cinnamomea or M. smythiesii. 2 Apparently M. beccarii is a rare species, in Borneo mainly collected in Sarawak (1st & 2nd Div.) and eastern Kalimantan; only two collections are known from Riau, Sumatra (pointing to Corner's Riau-pocket distribution type).
