Alangium javanicum (Bloemb.) Wangerin var. jaheri Bloemb. (1935) 284, f. 5bb; (1939) 221, f. 10bb. — Type: Jaheri s.n. (holo BO n.v.), Kai Isl.

The variety was described as follows: “ Fruit 32–33 mm long, 13–15 mm broad, 8–9 mm thick, with 10–12 thick and obtuse ribs, and deep grooves. Flowers unknown”.

We have not found the Jaheri collection and we do not know whether Bloembergen when describing the variety had a leafy twig at hand or only fruit, but we assume that the described fruit belongs to the section Conostigma . The variety may belong to A. minahassicum (fruit smooth) or to A. hollrungii (fruit presumably smooth). When the described ribs are not an artefact, it may represent a distinct taxon.
