Sori indusiate, linear, continuous, on a transverse receptacle 

 approximate to the costa. Indusium linear, opening along the 

 inward side. Veins springing from a central costa, immersed ; 

 venules reticulated, forming a series of large angular areoles 

 next the costa, other narrower ones often extending nearly to the 

 margin ; ultimate veinlets free and thickened at the apex. 



Fronds pinnatifid, subcoriaceous, with opaque black stipites 

 in the only species yet known. This genus is exactly the 

 counterpart of Blechnum in all but the venation of the fronds, 

 which is distinctly, not casually or accidentally, reticulated. 

 The only species B. melanopus is an Indian fern, having 

 much resemblance to Blechnum occidentale. 

 Ex. : B. melanopus, Moore.
