The differences between the varieties vema and serotina are consider- 

 able, and by taking the characters assigned to each I find it easy to divide 

 between them the examples of the aggregate B. Odontites. Vema is 

 more a weed of cultivated fields than serotina. I think the latter is the 

 commoner plant-
