Rhizome short-creeping. Stipes approximate, castaneous, naked, + 10—15 

 c.M. long, the fertile fronds on the longest stipes. Fronds moderately firm, 

 rather rigid, 7 — 10 c.M. long. Lowest pinnae much the largest and most 

 compound, ultimate segments obovate-cuneate, 2 — oVj m.M. broad. Both 

 surfaces naked. Fertile fronds similar, but with the under surface densely 

 coated with golden, waxy powder. Sori at length confluent, covering 

 nearly the whole breadth of the fertile segments, but do not reach the tips.
