Not forked, the moderately long and stout branches with basal cata- 

 phyls only, dioecious?. Internodes rather short (2-4x20-50 mm.), smooth, 

 ancipitally flattened becoming terete. Cataphyls a single pair, nearly 

 basal, rather blunt and white margined. Leaves lanceolate, obtuse, at 

 length 1.5x8-15 cm., rather distinctly but finely nerved, cuneately atten- 

 uate for about 10 mm. Spikes mostly solitary, rather short (15-25 mm.), 

 slender, smooth, with about 4 joints some 6-flowered in 4+2 series when 

 pistillate: peduncle 1-3 mm. long, sometimes with more than one joint: 

 scales ciliolate. Fruit (immature) ovoid, 2x3 mm., smooth: sepals in- 

 flexed. Plate 78.
