Sori round or oval, superficial or buried in 
the hairs. Fronds asa rule simple, covered 
beneath with a dense coating of stellate hairs.’ 
Veins copiously anastomosing, obscure, undefin- 
ed or evident with the main veins prominent. 
Fertile fronds more or less contracted and 
longer than the sterile. 
Niphobolus adnascens Kaulf. 
Rhizome long, creeping, scaly. Stipes scaly, 
Fronds 2-8 inches long, simple, entire; of two 
kinds, the barren ones oval-lanceolate; the 
fertile ones narrower, linear-lanceolate with the 
apex blunt or acute. The upper surface smooth 
and green, the lower covered with stellate 
(star-shaped) hairs, often very densely. Texture 
fleshy to leathery. Midrib prominent, veins 
immersed in the substance of the frond, anasto- 
mosing, the areoles including 2-4 free veinlets 
which are club-shaped at their apices. Sori 
often restricted to the upper half of the frond, 
reddish brown in colour ; sporangia mixed with 
long-stalked stellate hairs. 
In some specimens examined by us the 
distinction between sterile and fertile fronds does 
not exist.
