Nicobariodendron sleumeri is a
dioecious evergreen tree of 8–35 m high, with simple, alternately set leaves without
stipules. A leaf consists of a
leaf stalk of 3–8 mm long, and an oblong oval to oblong inverted egg-shaped, leathery, hairless and shiny green
leaf blade of 5½-10 × 2–4 cm, with a foot that gradually narrows into the leaf stalk, an entire margin, and a blunt end that abruptly changes in a pointed tip of ½-1¼ cm. The leaf is
pinnately veined with five to nine pairs of secondary veins. Male flowers sit in
spikes in the
axils of the leaves. These flowers are said to be fragrant, white, small, about 2 mm in diameter, and
tetra- or pentamerous, the petals are yellowish. They contain only two free
stamens, lying side-by-side, consisting of a filament of 1½-2½ mm long topped with an orbicular
anther of ½-¾ mm, borne outside the disc and a short sterile pistil in the middle. Female flowers are mostly in
cymes at the end of the branches. The conical fruit is a light red
drupe of about 2 cm, with the
calyx still present at its base, and it contains a single basal seed. == Taxonomy ==
