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.

Brassica juncea - Chinese Mustard

Chinese Mustard has not been seen since 1925 and was probably only a casual at the three places it was found: Eastern Green, Penzance (SW43V, 1889, W.A.Glasson), between Truro and Malpas (SW84G, Botanical Exchange Club, 1923) and at Bude (SS20D, 1925, E.Thurston).
