More or less pseudodichotomous or verticillate, the long branches with 

 basal cataphyls only, androgynous. Internodes moderate (2-5x30-70 

 mm.), smooth, for a time strongly ancipital. Cataphyls a nearly basal

 and pointed. Leaves lanceolate to oblanceolate or somewhat ovate, very 

 obtuse to acuminate, 2-4x7-15 cm., cuneately subpetioled for 5-10 mm. 

 Spikes often clustered, moderate (30, lengthening to 50 mm.), with 4-6 

 short rather stout joints some 10-flowered in 4+2 series : peduncle very 

 short, with 1 or 2 basal pairs of scales: scales ciliolate. Fruit round-
