Dioicous; in loose wide dull deep-green or yellow-green tufts, 

 ochreous-brown at base. Stems tripinnate, very long, trailing and fixed 

 by numerous purple radicles, densely coated with lanceolate or branched 

 paraphyllia, stoloniform and rooting at the apex. Stem leaves distant, 

 from a decurrent deltoid-obcordate base, deeply concave and 4-sulcate, 

 suddenly narrowed into a lanceolate irregularly serrulate recurved point; 

 both surfaces covered with acute papillae curved upward ; margin 

 subrevolute, crenulate, nerve ending abruptly below the apex. Branch- 

 leaves ovate, concave, more chlorophyllose ; ramuline leaves minute, 

 ovato-lanceolate, the apex formed of a single elongated hyaline smooth 

 cell. Perich. bracts pale, inner plicate, long and lanceolate, suddenly 

 running out into a serrated flexuose strap-like hair three times the 

 length of bract, the margins of the latter in upper half fringed with very 

 long simple or branched filiform toothed cilia, outer not ciliate, serrated 

 papillose. Capsule on a long smooth rufous-purple seta, large, rufous, 

 elongate-cylindraceous, arcuate, slightly contracted below the mouth 

 when dry, lid of the same colour, conico-rostrate, annulus indistinct.
