Distribution and Ecology
Occurs in NEQ, known only from collections made in the Bloomfield-Rossville area. Altitudinal range not known, but collected at 200 m. Grows in disturbed areas in lowland and upland rain forest. Also occurs in Papua New Guinea, Bismark Islands, New Ireland and the Solomon Islands.
Possibly the largest araliad known. The vegetative shoots arise in pairs or whorls from below the terminal inflorescence buds. Several flushes of growth occur as an inflorescence bud matures so that at anthesis the inflorescences are situated in forks well below the leafy crown with a succession of younger inflorescence buds in higher forks. Philipson (1979).
