L. biseriata Aust. is a doubtful species founded on few 

 broken stems without fruit that were mixed with other species 

 of this genus collected in 1845 by Sullivant near Augusta, Ga. 

 There is too much uncertainty regarding this plant to refer it 

 definitely. See Proceedings Phila. Acad. 1809, p. 225, also 

 Botanical Gazette, II, 142.

 middle, membranous, pale, the valves erect-spreading. Elaters 

 persistent at the apex of the valves, erect, unispiral. Leaves 

 inflexed to the base beneath. Amphigastria entire. Name 

 from Gr. phragma, partition, and koma, hair, from the position 

 of the elaters.
