Sedges and Rushes of Hot Springs National Park and 



Vicinity 



Francis J. Scully 



While making a collection of grasses of Hot Springs National 

 Park and vicinity a number of plants were collected which proved 

 to be the vegetative stage of many different species of sedges. Dur- 

 ing the next year a careful survey of this area was made for sedges, 

 attempting to collect them in the fruiting stage so the determina- 

 tions would be more accurate. The following forty-six species of 

 sedges represent this collection. Included also are twelve species 

 of rushes collected at the same time. The determinations of this 

 collection were made by E. C. Leonard of the Smithsonian Insti- 

 tution and E. J. Alexander of the New York Botanical Garden.
