2. no. 1871. t. 186. There are several varieties of this plant. 
Charlock is a common annual weed in corn-fields. The young 
plant is eaten in the spring as turnip-tops, and is considered not 
inferior to that vegetable. The seeds of it have sometimes been 
sold for feeding birds instead of rape ; but being hot in its nature, 
it often renders them diseased. _
