Cyperus dipsaciformis Fernald. Teasel-like Sedge. 



Cyperus dipsaciforniis 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 IMorong's handwriting "Sandy Pine Barrens, New 

 Jersey, Coll. Morong, September, 187:3." This is our only evi- 

 dence of its occurrence in our region.* 



Cyperus ovularis (Michx.). Globose Sedge. 

 PL XVL, Fig. 4.

 lina].

Cyperus ovularis Knieskern 34. — Willis 67. — Britton 261. — Keller and Brown

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 b}' S. W. Conrad at Fish House on 

 the Delaware, and now in the Philadelphia Academy Flerbarium, 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.
