A variable species in its size and in the length and breadth 
of the pinnules. Fronds one and a half to two feet long, 
stipes nearly as much, and, as well as the main rachis, 
rich, glossy, mahogany brown. Rarely I have seen the 
frond bipinnate, with the pinne very much elongated, as if 
unnaturally drawn up among other plants. The remarkable 
feature of this species is the large size of the lowest pair of 
segments or pinnules of the pinne, and their being so closely 
attached to the rachis that their base laps over it. The 
veins are free, as of the true Gymnogramme (Leptogramme, 
J Sm.) The sori are oblong, obtuse, rather short.
