 A very variable species. One or more of the narrow-podded forms is 

 in some places associated with b. brachijcarpa. One of our earliest 

 plants to flower, so that not unfrequently by the end of jMarch it has 

 ripened and shed some of its seeds. It is too much of a local species to 

 go into the ' very common ' category, although in profusion in certain 

 parts of the country. Besides brachycai^a we have at least two well- 

 marked forms. 



Liuiaria biennis, Moench. Occasionally subspontaneous on banks, or 

 in bushy spots about gardens.
