 obtuse, delicately ribbed and cross-lined. — ■ Sandy (mostly 

 brackish) shores, Nfd. to N. Y. and Pa.; the Great Lakes, and 

 weslw. Fig. 579. 



Ii5. J. filif6rmis L. Scape very slender (1.5-6 dm. high), 

 pliant ; cyme fevf-flowered, almost simple ; flowers 3 mm. 

 long ; sepals lanceolate, petals a little shorter and less acute, 

 mostly longer than the obtuse greenish capsule ; anthers 

 shorter than the filaments ; style very short ; 

 seed (0.5 mm. long) short-pointed at both 

 ends, indistinctly reticulated. — ^Wet shores 

 and bogs,Nid. to Sask., Pa., Mich., Rocky

16. J. effisus L. (Common or Soft 

 Kush.) Scape soft and pliant (3-12 dm. 

 high) ; inner sheaths awned ; cyme diffusely 

 much branched, many-flowered ; prophyllum below the indi- 

 yidual flowers broad-ovate; flowers small (2-2.5 mm. long), 

 greenish ; sepals lanceolate, very acute, as long as the narrow 

 triangular-obovoid retuse and pointless greenish-brown capsule ; 

 anthers as long as the fiiaments ; style very short ; seeds small seedxM.' 

 (0.5 mm. long), with short pale points. — Marshy ground, very 

 common. (Cosmop.) Var. compActus Lejeune & Courtois. 

 dense, glomerulate. — Less common, except in N. S., where abundant. 



17. J. conglomeratus L. Similar to the last ; scapes more rigid (3-7 dm. 

 high), distinctly sulcate or even costate below the inflorescence ; glomerule 1-2 

 cm. in diameter ; prophyllum lanceolate ; flowers about 3 mm. 

 long, brown or greenish ; sepals somewhat exceeding the 

 short-muoronate capsule ; anthers shorter than the fila- 

 ments. (J. Leersii Marsson). — Ditches, etc., Nfd. and N. S. 

 (Eurasia.) 



18. J. Smithii Engelm. Scape rather slender (6-9 dm. 

 high) ; cyme few-fiowered, nearly simple ; sepals lanceolate, 

 acute ; petals a little shorter, obtusish, shorter than the 

 broadly ovoid rather triangular acute deep chestnut^brown 

 capsule ; anthers as long as the filaments ; style sliort ; seeds 

 large (nearly 1 mm. long), obtuse, shortappendaged at 

 both ends, many-ribbed and reticulated. (J. gymnocarpu.i

§ 2. Flowers eprophyllate, i.e. with only the bractlet at base of the very short, 



pedicel. 



* Leaves terete, scape-like, not septate. 



19. J. Roemerianus Scheele. Scape stout and rigid (0.5-1.5 m. high), its 

 apex as well as the leaves pungent ; cyme com.pound, open and spreading, 

 brown; 3-6 greenish or light brown flowers (3-3.5 mm. long) in a cluster; 

 sepals lanceolate, sharp-pointed, longer than the obtusish petals ; anthers much 

 longer than the broad filaments ; styles shorter than the ovary ; seeds (0.7 mm. 

 long) very delicately ribbed. — Brackish marshes, N. J. to Fla. and Tex. 



20. J. maritimus Lam. Resembling the last, but with a rigid contracted green 

 cyme, an ovary attenuated into a style of nearly its own length, a greenish acute 

 capsule which usually exceeds the acute sepals, and seeds with distinct tails and 

 Stronger ribs. — Coney Island, N. Y. (Widely distr.) 



* * Leaves nodulose, i.e. with septa at regular intervals. 



21. J. dsper Engelm. Stems tufted, erect (0.4-1 m. high), terete, stout, 

 rigid, and with the rigid leaves rough ; cyme with rigid slightly spreading.
