The unusually extensive native range is explained by the ability of the seeds to remain viable while floating in sea water for up to 5 years, enabling the seeds to drift nearly worldwide. Germination occurs when the hard outer seed coat is abraded by waves on sand and gravel.
The leaves of the plant are used in Chinese traditional medicine.
Chinese used this Pacific Rim wild food as a tonic for the urinary organs and intestinal tract. Eskimo considered the peas poisonous…Iroquois treated rheumatism with cooked whole young plant.
Known Hazards :The pods can be eaten but like many members of the genus Lathyrus they contain -diaminopropionic acid, which can cause paralysis called lathyrism.
