Leaves laxly spirally arranged to subdistichous to partly subopposite; lamina oblong to elliptic or to (sub)obovate, 3–15(–18) by (1–)2– 5(–7) cm, (almost) symmetric, chartaceous to subcoriaceous, apex acuminate to subcaudate (or to obtuse), base equilateral to slightly inequilateral, cuneate to rounded, margin (sub)entire; upper surface sparsely whitish to brownish strigillose, mainly on the midrib (or glabrous), smooth, lower surface sparsely brownish to whitish strigillose on the main veins, smooth, cystoliths only beneath; lateral veins (4–)6–10 pairs, none of them furcate away from the margin, tertiary venation reticulate or towards the margin (sub)scalariform; waxy glands in the axils of some of the lateral veins in the middle part of the lamina; petiole 0.3–1.5(–3.5) cm long, sparsely brownish to whitish strigillose, the epidermis flaking off; stipules 0.5 –1.8 cm long, subglabrous or strigillose mainly on the keel, caducous or (sub)persistent (when juvenile). Figs on (the lower part of) the trunk, in (clusters of) up to 8 cm long, branched leafless branchlets with terminally c. 3 mm long scale-like persistent stipules; peduncle 0.4–1.2 cm long, minutely puberulous; basal bracts 3, verticillate, 2 –3 mm long; receptacle subglobose to depressed-globose, 1–1.5(–1.8) cm diam when dry, minutely puberulous to glabrous, non-stipitate, ribbed, without lateral bracts, with (warty) lenticels and the epidermis flaking off, pinkish to brick-red to red-brown, turning (finally?) black at maturity, apex slightly convex to flat to concave, ostiole 3 – 4 mm diam, with the upper ostiolar bracts horizontal, surrounded by 4– 5 short erect to inflexed apical bracts; internal hairs sparse and brown or absent. Staminate flower with one stamen. Style of the long-styled flower glabrous or minutely hairy, the stigma often distinctly papillate.

Distribution — Indonesia, Southern and Central Sulawesi.

Habitat — Forest at altitudes up to 1900 m.

Notes — A photograph of the figs shows that the apex of the receptacle is concave in fresh state and that apparently mature figs are black, an unusual colour in subg. Sycomorus .

This species is more variable than the closely related F. sulawesiana .

In juvenile material, the stipules are subpersistent.
