 stems sturdy in the lower part, closely enveloped by the large, 

 long, loose, somewhat sparsely hairy leaf- sheaths, or in the shoots 

 which have shot forth after tlie forest fires, with a much shorter 

 and not strongly developed lowest internode and .sheath ; upper 

 Hheatli cylindrical, closely enveloping and about ^ to ^ the length 

 of the slender terete internode, glabrous except at the pilose 

 mouth ; Ugule conspicuous, red-brown, membranous ; blade long,

 .slender, drooping, three or four together, bearing 1 to 4 lanceolate 

 acuminate purplish spathes, jjedicels i to I as long as the spathe,
