pinna form a cross. The leaf-stalk is smooth, and without pinnae 
on the lower half. Sori round, distinct, very small, brown, and 
seated around the margin of the pinnules. 
The pendulous character of the lower pinna}, and the cruciform direction of 
their bases are most apparent in vigorous plants, and serve as characters which 
immediately distinguish this plant from its congeners.
