&S2. J. militaris, Big. Fl. Bost. ed. 2, p. 139. Not rare 

 in Rhode Island ! 



833. J. . A late flowering species, with very lax pan- 

 icles, and not described in any work that I possess. I am 

 unwilling, however, to describe it as a new species without 

 farther information. Wet, sandy places, Rhode Island ' 



XYRIDACE^]. 



834. Xyris . A very large species, with leaves as 



large as our common Iris, found at Sneech pond ! Cumberland, 

 on floating land. I am confident this will prove to be a new 

 species, but I leave it undescribed, as I believe that it was dis- 

 covered previously by others. 



CYPERACE^L 

 I have generally followed the monograph of N. A. Cypera- 

 ceae in its nomenclature, and am under obligation to the distin- 

 guished author of this excellent work for much assistance in 

 determining the doubtful plants of this interesting order.
