Taxonomy
Possibly related to this but collected at 3000 m in the Wichmann Mts of southwest New Guinea is a juvenile form with paripinnate and imparipinnate leaflets, which are deeply lobed like those of some forms of Dysoxylum mollissimum, D. variabile and D. bijugum (Lab.) Seem. from New Hebrides, New Caledonia and Norfolk Is. It has been collected once (von Römer 1333, in BO).
This is closely related to Dysoxylum mollissimum Blume but differs in its smaller leaves with fewer leaflets, of which the terminal is scarcely developed, its small flowers, and less hairy tube.
