Seed photos by María Fernanda González Giraldo.
Arenga undulatifolia is one of Borneo’s most common forest palms often growing next to rivers but also found to at least 1,000m in the hills. There is only a short trunk and Arenga undulatifolia often appears to have no trunk at all.
The round fruit which ripen brown green are dispersed by Palm Civets which eat the fruit and defecate the seeds in a neat pile on paths and roadsides in forested areas.
The hard black seeds are also common drift seeds on coastal beaches but A. undulatifolia does not grow along the coast.
