fault, for there Is a specimen in the Torrey Herbarium dating back 

 to 1864. Mr. Smith has sent me the following note on the 

 locality: " It is in a small patch of Sphagnum in a field, 300 feet 

 above tide- water." Mr. Martindale has it from the ballast 

 grounds at Camden, but there seems no doubt that the Delaware 

 County plant is a native. It is not quite as stout as the plants 

 from Asia and Mauritius, but agrees very well with French speci- 

 mens in Herb. Torrey. 



Scirptis stenophyllus. Ell. {Isolepis stenophylla, Torr.), appears 

 to be a true Scirpus^ and is nearly related to S. barbatus^ Rottb., 

 to which it has been referred by Boeckeler, Linnaea, xxxvi., p. 

 792, as var. Americamis. It seems to me specifically distinct, 

 but if reducible to a variety of RottbolUs species, a result by no 

 means impossible when more material is obtained, it must bear 

 Elliott's name.

In taking up the name I am guided by Boeckeler in Linnaea, 

 xxxvii., p. 572, who states that he saw a specimen named by 

 Lamarck in Willdenow's Herbarium.
