Notes
Of the three specimens from Papua, one (SCHODDE 5550) has flowers and fruit which enabled to examine the stamens: one flower had 6 and another 5 + a staminode. This specimen agrees also in the inconspicuously dentate leaf margin. The other sheet (BRASS 23154) has only fruits, but the stigma is typical for S. lobosporus; however, it has distinctly dentate leaves and racemes up to 5 cm in fruit, which is atypical for S. lobosporus. The third specimen (For. Coll. Herb. Bulolo 8458) has hairy infructescences, the two others being glabrous, reducing differences with S. arfakensis to the stigma only!
In Queensland the species attains a height of 6-24 m and a stem diameter of 50 cm.
