Fronds 10-30 cm. high, 1.5-3 mm thick in diam. or much 

 thicker below, cylindrical, rising from scutate expanded disc, branch- 

 ing soon from the base in more or less. regularly dichotomo fastigi- 

 ate manner and the fronds assume a flabellate outline when spread 

 over paper. Branches erect or erecto-patent standing with narrow 

 axils and the upper segments are slenderer than the lower, and end 

 in roundish apices. When young frond is covered with downy hairs 

 but when old the hairs drop off leaving scars on the shoulders of 

 utriculi. Utriculi are cylindrico-clavate, 5-7 times long as the 

 diameter, mucronate, very acute when young, much shorter and often 

 obtuse when adult. Wall of the apical portion of utriculus is thick 

 and concentric striations are observed around the mucro which is 

 itself stratified with thick curved, concentric layers. Gamdangia 

 elongato-ovate (2x9/4 in one example), borne at about the middle 

 portion of an utriculus. Female gametes are green and globular 

 and much larger than male gametes which have milky appearence. 

 Colour deep green. Substance spongy and juicy and the plant in, 

 completely adheres to paper in drying.
