CASUAL AND ALIEN PLANTS FROM 
WAKEFIELD. 
JOHN CRYER. 
The following list consists mainly of Casual and Alien 
Plants noted by “the writer on the banks of the River Calder 
at Wakefield during the past twelve years. Over ninety per 
cent of the total seen were discovered on a piece of land about 
two hundred square yards in extent in a pasture close to the 
river. They are no doubt the outcome of sweepings thrown 
out by the barge men.
