Quick Summary

The genus Phytelephas refers to a group of South American palms known for their hard, nut-like seeds, commonly called ivory nuts. These seeds contain a dense endosperm that can be carved and turned, similar to actual ivory, hence the name "vegetable ivory". The palms themselves are characterized by pinnate leaves and drooping flower spikes. The name Phytelephas is derived from Greek words meaning "plant" and "elephant" or "ivory," highlighting the material's resemblance to elephant ivory.12
