Nearly allied to 5. halophiluni Greene, and possibly a vari- 

 ety of that species, although I am, inclined to regard it as quite 

 distinct. It is a taller, and more slender olant than .9. 7

of a very perceptibly brighter and more yellowish shade of green 

 and with straighter and more clustered stems ; these are long and 

 exceedingly slender with the wings reduced to little more than 

 membranous edges. The narrower leaves are less strongly striate 

 and thickened than in S. halophilum and more slenderly attenuate, 

 and are apparently also without the abrupt membranous expansion 

 at the extreme base although narrowly clasping below for a longer 

 distance. The purplish spathes are less flattened and less decidedly 

 two-edged below, the narrow^er bracts less strongly striate, nar- 

 rower and usually more unequal, the outer one less convex with

longer linear tip, the inner one more abruptly scarious-obtuse ; the 

 capsules are smaller, more pyriform, thinner-walled, less strongly 

 trigonous and more rugulose and scabrous-puberulent.

Growing in small tufts 10-25 cm. high, pale and glaucous, 



discoloring slightly in drying. Leaves Yz-yi the height of the 



. taller stems, equaling the shorter ones, stiff and erect, mostly se- 

 taceously slender and .5-1 mm. wide, rarely 1.5 mm., finely close- 

 striate, attenuate to an acute point: stems equally slender with the 

 leaves, stiff and narrowl)^ firm-margined, the edges like those of 

 the leaves smooth pr, when young, minutely denticulate : spathes 

 small, purplish or green, often partly double, one or more flowers 

 arising from between the short proper spathe and the closely sub- 

 tending slenderly prolonged outer bract; inner bract 13-20 mm. 

 long, mostly attenuate and acute, the outer one 2.5-4 cm. long, 

 and united-clasping for 2-3 mm. at base; both bracts hyaline- 

 margined; interior scales about ^A the length of the pedicels; 



flowers very small, apparently not more than 3-4 on erect pedicels 

 usually shorter than the inner bract; perianth 4-7 mm. long,
