›Magnoliopsida›Poaceae›Phalaris›Phalaris canariensis
Ecology
An annual of waste ground, rubbish tips, walls, roadsides and pavement cracks, especially in built-up areas. It is a casual, rarely persisting, from bird-seed, grain and, possibly, wool shoddy. Generally lowland, but reaching 430 m at Nenthead (Cumberland).
Status
Neophyte
Trends
P. canariensis was recorded in the wild as early as 1632. Comparison with the 1962 Atlas suggests that losses have been balanced by new records.
World Distribution
Perhaps native to N.W. Africa and the Canary Islands; widely naturalised in the Mediterranean region and in other continents.
