Plants long, slender, light yellowish-green to yellow-brown, in loose tufts, 

 pendulous from trees; stems slender, to 30 em or more long, with leaves mostly 

 1 mm wide, rarely branched, the branches mostly ventral, leafy. Rhizoids not 

 seen. Line of leaf insertion transverse. Leaves very widely spreading, the bases 

 imbricate, slightly asymmetric, long, rectangular, to 4 mm long, less than 1 mm 

 wide at the base, bifid to one-half of their length ; segments long, linear, acute to 

 acuminate by one or two cells, entire, the vitta strong, three-fourths of the 

 width of the base of the segment, extending to the tip of the segment ; lamina 

 long, with only occasional decurved cilia at the base, the vitta bifurcate at the 

 sinus ; leaf-cells thick-walled, the trigones occasionally distinct, thin-walled pits 

 occasional, the cuticle coarsely verruculose. Underleaves as large as and like the 

 leaves, squarrose when moist, symmetric. Plants dioicous. Male inflorescence
