 sessile or nearly so, 30 to 40 cm. high, one-fourth as broad, obtuse, attenuate 

 to base, coriaceous, upper surface with apprcssed scattered cottony fibers,

Fronds articulate to the rhizome, the fertile and .sterile rarely ditTerent. 

 the sterile always green, glabrous or the pubescence not stellate; sori 

 dorsal on the frond, dorsal or terminal on the veins, or on their anas- 

 tomoses, without indusia. A very large genus, including ferns of every 

 habitat, the Philippine species never bipinnate. The preceding and the 

 four following genera are derived from Pohjpoditim, and intimately related 

 to some of its sections. The subgenera are sometimes regarded as genera, 

 as also have been various minor divisions not recognized at all in this 

 arrangement, but all are very intimately related, and their separation 

 costs as much as it gains in convenience, beside demanding many new 

 names.
