73 b. Matricaria discoidea, DC. I have no doubt of this plant 

 being a native here, and not introduced from Oregon or California, 

 as Torrey and Gray (Flora, II, 413) suggest. It grows not only 

 on wastes and roadsides near and even in St. Louis — (here it is 

 found with Maruta Cotula, but flowers before this is six inches 

 above ground) — but also four or five miles from the town, on 

 grassy spots in the woods.

84. Cuscuta Cephalanthi, Engelm. Well distinguished by its 

 small cylindric flowers, and by the corolla remaining on top of the 

 capsule. It is found more on Vernonia fasciculata than on Ce- 

 phalanthus. So far only found near St. Louis. 



85. Lepidanche Compositarum, Engelm. So far only found 

 in the prairies of Indiana, Illinois and Missouri. Cuscuta glome- 

 rata, Choisy. 



86. Myosotis verna, Nutt. ? If the description of Myosotis ver- 

 na given in some American floras is correct, our plant cannot be 

 the true verna. But as I have neither seen Nuttall's character, 

 nor original specimens, nor eastern specimens at all, I must leave
