Stem erect, hollow, branched, smooth. Leaver lanceolate, their margins 

 rough, with rather long scabrous hairs pointing forwards ; the nerves 

 beneath, particularly the midrib and a narrow space on the margins of

 truncate, their numerous nerves running out into very long and stiff 

 setose points, slightly hairy, the hairs adpressed. Flowers in small rather 

 lax stalked twin spikes ; bracteœ somewhat distant, turbinate, rather 

 long, fringed with long stiff setose points, 1 — 4-flowered, flowers 5-ticl, 

 " 6— 8-androus" semitrigynous ; pedicels jointed just below the flower.
