CRUCIFER^. * 19 



SINAPIS, L. 



37. S. arvensis, L. Common Charlock, ' Charlick.^ 



Colonist, or Native ; in arable land, on banks and in waste spots 

 about cultivated fields. March to November. Very common. 

 Area general. 

 One of the commonest weeds among corn and other crops, often 

 making fields of a golden yellow with its flowers. A plant with 

 flowers of a cream colour, with others, in a field near Langdon

 The name of the genus, Sinapis, or rather its old English equivalent, 

 Senvy, has been corrupted by the countryfolk into ' Siney,' and is noAv 

 applied by them not to the Charlock, nor to any species of the genus, but 

 to another plant of the Order Crucifer^e, the Hesjoeris matroyialis, the 

 double variety of which is common in their gardens.
