 slender, with fastigiate branches. Leaves in three ranks, crowded, 

 straight, erect, from a lanceolate concave whitish base, gradually nar- 

 rowed into a short broad obtuse entire subula : nerve thin below, dilated 

 above ; cells pellucid, large and elongato-rectangular at base, quadrato- 

 rectangular and incrassate above. Perich. bracts longer, the nerve 

 excurrent in a longer subula, slightly recurved at apex. Capsule on a 

 yellow seta, pachydermous, subspherical with a swollen neck, when dry 

 and deoperculate, truncate smooth brownish-yellow ; lid large, orange,

The longer slender branches, which in the moist state show distinctly 

 the trifarious arrangement of the leaves, afford a ready means of identification.
