Distribution and Ecology

Occurs in CYP, NEQ, CEQ and southwards as far as coastal central New South Wales. Altitudinal range from near sea level to 1000 m. Grows in well developed lowland and upland rain forest and is +/- saprophytic deriving nourishment from rotting wood in old stumps, logs, etc. Also occurs in New Guinea.

Natural History & Notes

Although plants are not completely devoid of chlorophyll, they are generally accepted as being saprophytic and field evidence supports this contention as plants are usually found near large rotting stumps.
