Root a very small callous disc, throwing out numerous cylindrical 

 creeping branched fibres, variously matted together and rising at 

 length into new fronds. Fronds numerous from the same base, 

 growing in thick tufts, 4-5 cm. high, cylindrical or compressed, 

 200-500 ^ broad, of almost equal thickness throught, erect, but 

 often incurved and somewhat entangled, mostly naked below, and 

 branched upward with 2-3 sometimes 4 or more branchlets from 

 same place so as to appear like clustered, with branches of the 

 next order similarly loaded in turn ; besides a few ramuli are 

 irregularly scattered along the branches. Branches are patent and 

 blunt or pointed at apex. Tetraspores collected in the extremities 

 of the branches which swell in lanceolate or spatulate manner or 

 in somewhat expanded portions beneath apex.
