54 Schollera gramincus. 



lower leaves. Leaves linear, from three to twelve inches long, light- 

 green, succulent. Flowers solitary, consisting of six, linear, yellow 

 petals, which expand on the surface of the water at low tide. I have 

 found it frequently rooting in the earth by the side of streams and 

 flowering there. Very common throughout all the middle, southern, 

 and western states in rivers and creeks — abundant in the Schuylkill 

 river near this city. Flowers in July. 



The figure represents the plant, as large as nature.
