ERIOPHORUM L. 



Key to the Species. 



a. Leaves very slender, 1-1.5 mm- broad, triangular-channelled, a single in- 

 volucral bract, pappus pure white. 

 b. Upper cauline leaf with blade very short, less than sheath. 



E. gracile, p. 274 

 bb. Upper cauline leaf with blade longer than sheath. E. temellum, p. 273 

 aa. Leaves flat, involucral bracts, two or more, pappus more or less rusty. 



E. virginicum, p. 274 

 Eriophorum tenellum Nutt. Few-nerved Cotton-grass. 

 PI. XIX., Fig. S- 

 Eriophorum tenellum Nuttall, Gen. Additions (p. i), 1818 [New Jersey]. 

 Eriophorum, angustifolium Barton, Fl. Phila. I. 37. 1818. 

 Eriophorum polystachyon Knieskern 34. — Willis 68. — Britton 265. 

 Eriophorum gracile Keller and Brown 66. 



In bogs of the Pine Barren district, also very rare or local in 

 similar situations in west Jersey and the Cape May peninsula. 

 As all the specimens so far obtained in our region are B. tenellum 

 (except one colony of H. gracile), I am inclined to think that 

 Dr; Knieskern's were the same and not £. polystachyon, as he 

 stated. Willis and Britton simply copied his record. 



Fr. — Early June to late June.
