" Root s small disc. Stem simple or sometimes branched, 

 compressed or almost cylindrical, short, 0.5-1 cm. long, soon passing 

 into the oval or subcuneate base of the frond. Frond tufted or 

 solitary, flat, lanceolate, slightly thickened at the margin, 1.5-6 cm. 

 broad, rarely simple, usually constricted at long intervals so as to 

 form something like nodes, branches arising proliferously from the 

 nodes or apex. Apex of frond generally dissolved into two, three or 

 mere frondlets or branches, rarely simple and subulate. Branches either

 some small specimens. Smaller prolifications constricted at the base,
