Flora of Cornwall (1999)

The descriptive text, below the map, is from the Flora of Cornwall (1999), which was a Tetrad Atlas (the maps had 2km square dots or Tetrads). The map on this web page depicts the plant's distribution at the 1km square scale and shows the records made pre-2000 which were used in the 1999 Flora and those made since.

Lathyrus japonicus subsp. maritimus - Sea Pea

\fbidis \ltrpar\fi480 Nationally Scarce, Sea Pea has always been rare in this area, but there are records for it on the Isles of Scilly (1972 and 1977) and one record from Church Cove, Gunwalloe (SW62Q, 1982, A.J.Byfield). Nelson (1986) suggests that the very large numbers of seeds of Sea Pea (Lathyrus japonicus ssp. maritimus) found on Cornish beaches could not be produced by local plants, as the species is very rare in Cornwall, and he concludes that they must be oceanic drift seeds from the N.E.American coast. Several seeds from the driftline at Hayle flowered in cultivation in 1983.
