parallel to the main rhachis covering it; the secondary rhachis greenish

f the pinnae, the others cut to the rhachis into 2—7 linear segments 
which dilate into a clavate apex. Veins single in each segment, the fertile 
ones expanding at the apex into one or two transverse horns to form a 
straight or semilunar receptacle, which is exceptionally also supported by 
a small fork-branch issuing from near the apex. Sorus filling the entire 
width of the apex. Invol. even with the margin, straight or reniform, open
