Very local and perhaps now extinct in the Salford Borough. Marl pit at Ellenbrook
(SD7201, DP Earl, 1991) but not seen on a return visit in 2009; old wet meadows
grazed by horses at Ellenbrook (SD7201 & SD7301) now thought to be lost to
housing development. There is a Greater Manchester Plant Atlas record for Clifton
Moss (SD7603).
