Dioicous, cjespitose, medium to largish in size, of a yellowish- 

 brown colour. Stems simple or slightly irrejrularly furcate, 

 flexuose, filiform, rigid and somewhat brittle when dry, erect or 

 procumbent, on a cross-section 15 cells in diameter, cells opaque, 

 cortical cells 40-50, reddish-brown, smaller than the inner ; root- 

 lets few, near the base of the stem. Leaves closely imbricate, 

 bifarious, erect, appressed, semi-amplexicaul, subtransversely 

 inserted, sabquadrate, 1)roader than long, quadripartite, segments 

 lanceolate, acute, furrowed, margin outwardly curved, near the 

 base furnished with long recurved teeth ; texture firm, cells 

 smallish, roundish-quadrate or oblong roundish-quadrate, walls 

 very thick, no trigones. Stipules large, oblong-subquadrate or 

 ovate, bipartite, segments lanceolate, acute or acuminate, furrowed. 

 Bracts larger than the leaves, subquadrate, broader than long, 

 quadridentate to about the middle, segments broadly subulate 

 or lanceolate, acute or acuminate, furrowed, margin of bract and 

 segments laciniate-dentate ; bracteole oblong subquadrate, biden-

 at the base, margin laciniate-dentate. Perianth terminal, project-

 mouth delicate, hyaline, laciniate-ciliate, cilia 4-G cells long, 

 2 cells wide at the base; pistillidia 12-15. Male stems much 

 more slender, with more distant leaves.
