Scarcely forked, the moderate branches with basal cataphyls only, 

 androgynous. Internodes rather short (2-5x10-40 mm.), smooth, the up-

 ally followed by a second, spreading. Leaves elliptical or oblanceolate- 

 obovate, sometimes rather quadrate, obtuse, 1-2x2.5-5 cm., finely about 

 3-nerved and veiny, cuneately subsessile. Spikes mostly solitary, short 

 (15 mm.), with about 4 rounded joints some 6-flowered in 4-J-2 series: 

 peduncle nearly suppressed: scales ciliolate. Fruit round-ovoid, 4 mm. 

 in diameter, cellular-papillate or tuberculate: sepals erect, parted. j
