 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.
