Horsfieldia iryaghedhi deviates from all other Horsfieldias, and can be placed in a separate section. It is distinguishable by the leaves being papillate beneath, the male flowers arranged in compact heads, and a many-lobulate stigma; according to Warburg (I.e.: 334) the seeds contain some starch, possibly unique for this species.


Formerly in Java a wax was obtained after cooking the fruits. The wood is moderately heavy and even-grained (see Sinclair 1975: 72).
