2 The type, Endert 3996, with male flowers, is the only specimen from Kalimantan. The remaining specimens from Sarawak and Sabah somewhat differ in general appearance, their twigs are often less roughly hairy towards the apex, and their leaves are somewhat more coriaceous with the lateral nerves ascending at a slightly sharper angle to the midrib. 1 A similar species, H. xanthina, differs in the androecium and in a much shorter indumentum; H. montana differs in its globose male flowers of only 2 mm long. Horsfieldia endertii is characterized by ellipsoid male flowers 1.5-3.5 mm long, with an androecium which is distinctly longer than broad, not articulated pedicels, very coriaceous leaves, harsh-haired leaf buds, and inflorescences; on the lower leaf surface there are practically always pale-yellowish hair scars, visible with a lens. The species usually has ± rounded leaf tips, as in H. montana, but the leaves in the latter usually dry blackish and are only 4-14 cm long and thinner.
