Cornish Red Data (2009)

The descriptive text, below the map, is from the Cornish Red Data Book (2009). The map on this web page depicts the organisms distribution and shows the records made pre-2000 and those made since.

Lathyrus japonicus subsp. maritimus - Sea Pea

Range & Status

Native. European Boreo-arctic Montane element; a coastal species also known in E. Asia and N. America.

Regional Distribution

Always extremely rare in Cornwall, it was last recorded in 1999 at Godrevy Cove, on

The Lizard (SW82). In the Isles of Scilly it has also always been very rare with very few

records. In 2007 a few plants were found on a beach on St. Mary' s (SV91); by 2008 they had increased to c. 30 plants.

Habitat & Ecology

A plant of shingle beaches. Its aperiodic presence in Cornwall may be due to the chance successful germination of drift seeds.


Trampling by tourists would threaten its establishment on many beaches.
