1. Samolus pauciflorus Raf. (Samolus floribundus HBK.) Water Pim- 

 pernel. Map 1593. In wet places throughout the state. While I have no 

 specimen from the northwestern part of the state, there are several records 

 for that section. It is usually found on muddy and sandy bars and banks 

 of streams, in ditches, low places in woods, and cultivated fields. Although 

 it produces an abundance of seed, it is never abundant and is usually only 

 an occasional or infrequent plant.
