bury, Md., growing in water from six inches to two and a half feet deep. 

 Stems throwing out scaly -jointed runners from the base, which take root at 

 the joints, and sometimes produce a few delicate immersed leaves. Upper 

 part of stem and leaves sharply triangular, the involucre channelled or 

 bayonet-shaped, six to nine inches long. The credit of detecting this species 

 belongs to my friend, Albert Commons, of Delaware, who accompanied me in 

 one of my visits. 



Rhynchospora pallida, M. A. Curtis, Chapman's Flora, p. 527. Not un- 

 common in the Pine Barrens of New Jersey, especially near Quaker Bridge 

 and Atsion. June and July. This has probably been overlooked, from its 

 close external resemblance to R. alba, Vahl., but it is very distinct. 



Akistida lanata, Poir. Sandy soil near Salisbury, Md. October.
