'''''Lathyrus japonicus''''' ([[synonymy|syn.]] ''L. maritimus''; common names '''Sea Pea''', '''Beach Pea''', '''Circumpolar Pea''', '''Sea Vetchling''') is a [[legume]] native to temperate coastal areas of [[Asia]], [[Europe]], [[North America|North]] and [[South America]]. <br />
<br />
It is a [[herbaceous]] [[perennial plant]] growing trailing stems to 50-80 cm long, typically on sand and gravel storm beaches. The [[leaf|leaves]] are waxy glaucous green, 5-10 cm long, pinnate, with 2-5 pairs of leaflets, the terminal leaflet usually replaced by a twining tendril. The [[flower]]s are 14-22 mm broad, with a dark purple standard petal and paler purple wing and keel petals; they are produced in [[raceme]]s of 2-7 together.<br />
<br />
The unusually extensive native range is explained by the ability of the [[seed]]s 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.<br />
<br />
The pods can be eaten but like many members of the genus ''[[Lathyrus]]'' they contain β-oxalyl-''L''-α,β-diaminopropionic acid, which can cause paralysis called [[lathyrism]]. The leaves of the plant are used in Chinese traditional medicine.<br />
