2 Koorders 18136 (Sulawesi) is sterile but agrees in leaf colour and texture with the specimens from the Talaud Islands. 1 Horsfieldia talaudensis possibly is endemic on the Talaud Islands. It belongs to the group of species with firm, transversely ellipsoid to subglobose male buds, the androecium with strongly inflexed anthers, connate to about halfway, with slender hairy pedicels, and pubescent ovary (thinly pubescent young fruits).
