Very large and very hairy beneath, the sori minute, not marginal but rather 
medial, immersed; frond quadripinnate, pinnae and segments very regular. It has 
the habit of Microlepia Speluncae (L. ) Moore, but the frond is more papyraceous, 
shining and rather glabrous on the upper surface, the veins prominent beneath : 
stipes clustered. Microlepia ldrta Kaulf. differs in its broader pinnae and seg- 
ments, the latter less regular, thicker and more cuneate.
