Plant growing in dense tufts, formed by the numerous branches of 

 slender tough ahnost woody rhizome, each branch of which produces 

 numerous stems one befoi'e the other, intermingled with sheaths of the 

 stems of former years ; lowest sheaths broadly ovate-mucronate ; upper 

 ones with subulate points ; the uppermost sheath terminating in a 

 narrow bayonet-shaped leaf from i to 1 inch long. Stems 2 to 8 inches 

 high, with a filiform channelled leaf near the apex, of 1 to 5 inches 

 long ; shortly above this there are 2 bracts similar to the upper stem 

 leaf, which gives the apex of the stem the trifid appearance Avhence 

 the plant takes its name. Terminal leaf and bracts all erect, and all 

 attaining nearly the same height, which, however, varies considerably. 

 Perianth leaves about -^ inch long. Capsule shining, chestnut or

 leaves nai'rowly elliptical-lanceolate, acute, chestnut-brown, half as
