 light green. Leaves basal; blades about one-third the length of the scape, 

 1-1.25 mm. wide, sometimes involute; scapes grooved; inflorescence 3-10 

 cm. long, many-flowered, the branches ascending; flowers scattered, rather 

 distant; perianth straw-colored, 3-4 mm. long; sepals and petals nearly 

 equal, lanceolate-subulate, slenderly acute or acuminate, appressed or

 than the filaments; capsule oblong or rarely ovoid-oblong, about as long 

 as the perianth, obtuse or barely apiculate; seeds oblong, 0.35-0.50 mm. 

 long. In dry woods or on prairies, 111. to Wyo., Tenn., Miss, and Ariz.

 pale green. Leaves basal; blades about one-half the length of the scape, or 

 less, very narrowly linear, flat, frequently somewhat involute; scapes

 In damp soil and open places, Me. to Ont., Saskatchewan, Wash., Conn., 

 Tenn. and Mex. Spring and summer. Differs from J. tenuis by the

 of the inflorescence nearly erect, the flowers secund; perianth 4-5 mm. 

 long; stamens 6, half as long as the perianth, the anthers as long as 

 the filaments; capsule oblong, triquetrous, shorter than the perianth; 

 seeds larger than those of /. Vaseyi, about i5-ribbed, i mm. long, 

 short-tailed. In swamps, Me.
