Taxonomy
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.
