^^- Rhizome stout, creeping, more or less villous or hispid and scaly,

 j.vpurple-brown and covered with glandular pubescence. Fronds 

 scattered, i-4 ft. long, 3 in. - 2 ft. broad, also more or less glandular

 branches. Sori orbicular in two rows near the margin of the 

 pinnules, often covering the whole under-surface. 



A variable fei-n, very difficult to distinguish from Hypolepis tenui- 

 folium ; in the latter, however, the sori are strictly on the margin, 

 and are more or less covered by the recurved tooth of the frond or
