long and stout, stigmas very long : capsule broadly oval or obovoid, 

 rounded above and strongly apiculate, equaling or slightly exceed- 

 ing the perianth, placentae meeting at the axis or nearly so : seeds 

 broadly oblong (.5-6 mm. x .3-3.5 mm.), short-blunt-pointed at 

 each end, marked with 12-15 distinct longitudinal ridges, the 

 spaces between inconspicuously reticulated. 



Salt marshes along the coast from Newfoundland to Florida, 

 also inland in central New York, and on the Pacific Coast at Van- 

 couver Island (Macoun). Specimens were examined from nearly 

 all parts of this region. 



In America this is a very distinct species seeming to be quite 

 constant in its characters over our whole region, but in Europe /.

as to make distinction diffi- 



cult. The position of the leaves upon the stem and the short blunt 

 perianth divisions form two very conspicuous characters, and by 

 these it may be distinguished from all other species treated in this 

 paper.

Stems more or less tufted, tall and stiff, erect, rather slender 

 -8 dm. high), nearly terete : leaves very long (25-40 cm.), about 

 ^ length of culm, rigid and erect, terete, the groove very shallow 

 or wanting ; blade-bearing sheaths commonly only one, rarely 

 two, short, rather close, the margins and short auricles semi -mem- 

 branous, not scarious, lower sheaths bladeless and purple : inflo- 

 rescence small, rather crowded (10-35 mm - l° n g)> branches erect, 

 each with 2-4 sessile scattered flowers ; bracteoles obtuse and 

 rounded: perianth 3.5-4 mm. long, green or stramineous, rigid, 

 the parts erect or appressed, equal and similar, lanceolate, all acute 

 and narrowly scarious margined : stamens one half the length of 

 the perianth, anthers linear-oblong, nearly as long as the filaments : 

 stigmas short, sessile or nearly so : capsule 4-5 mm. long, oblong- 

 cylindrical, obtuse, slightly exceeding the perianth ; placentae 

 meeting at the axis: seeds .85-1.10 x .1-.15 mm. including the 

 tail, sigmoid-spindle-shaped, caudate at each end, the tails over 

 one half the length of the body, marked with about 1 5 very low 

 longitudinal anastomosing ridges, not reticulated between. 



Moist shores and wet woods, Maine and Ontario along the 

 lakes to the Saskatchewan, Iowa and Colorado. Specimens ex- 

 amined from various places both in the East and in the West.
