Cyperus dipsaciformis Fernald. Teasel-like Sedge. 



Cyperus dipsaciformis Fernald, Rhodora 106, p. 127 [near Washington, D. C.]. 



I am informed by Prof. M. L. Fernald that there is a specimen 

 in the Gray Herbarium from the herbarium of Thomas Morong, 

 labelled in Morong's handwriting "Sandy Pine Barrens, New 

 Jersey, Coll. Morong, September, 1873." I'his is our only evi- 

 dence of its occurrence in our region.* 



Cyperus ovularis (Michx.). Globose Sedge.

Common in open sandy ground throughout our region, except 

 in the Pine Barrens, and casual in the northern counties. 

 Fr. — Early July to early September. 



* A specimen collected many years ago by S. W. Conrad at Fish House on 

 the Delaware, and now in the Philadelphia Academy Herbarium, has been 

 identified by Dr. Britton as Cyperus refractus. The plant, however, is abor- 

 tive and not well developed, and I do not think it can be certainly identified 

 with this species. There is no other record for the state.
