2 The stomata on the lower leaf surface are deeply sunken in the surrounding tissue, which apparently is not papillose. 1 Myristica olivacea is close to M. cornutiflora from which it differs chiefly by its more slender habit. The twigs dry yellowish, the leaves conspicuously olivaceous-green. The flowers are similar to those of M. cornutiflora subsp. elegans, but differ in the persistent bracteole and longer androecium in proportion to the perianth. The leaves below apparently lack the small dark brown dashes and dots, but possibly the latter are represented as very small scattered points, only visible here and there (lens!).
