|Abstract||This remarkable rheophytic fern which is often massed in cracks of rocks in or near cascades in streams subject to sudden overflows had a peculiar distribution, being rather common in such habitats in Sumatra, Malaya, and Borneo, but also found on Mt. Salhutu in Ambon (Moluccas). It has recently also turned up in East New Guinea.|
