Rhizome thick, creeping, densely scaly; scales fusco-brown, ovate-lanceolate, 
acuminate, peltately attached, clathrate, nearly entire; frond dimorphous, 
ceespitose, stipe 30-60 cm long, terete underneath, bisulcate above, sparcely scaiy, 
sterile lamina 20-50 cm long, 15-28 em broad, obleng, impari-pinnate; pinne 4-10- 
jugate under the free trifurcate terminal one, which often prolongated and rooting 
at apex, 9-20 cm long, 2.5-5 cm broad, broadly lanceolate, opposite, the upper 
ones smaller and alternate, acuminate, base roundish or rotundo-truncate, shortly 
petiolate, margin crenate throughout, the rounded lobes bluntly serrate with a 
prominent seta at the sinus, rachis roundish underneath, broadly bisulcate above, 
glabrous on both sides; lateral main veins distinct, patent, 7 mm apart, intervening 
veinlets angularly anastomosing in 3 rows of areole between main veins and 2 
rows from costa outwards, areole shortly appendiculate or not, veinlets free to- 
wards margin; fertile frond similar to the sterile one but much contracted, 7-10 
cm broad ; pinne 6-8 cm long, about 1 cm broad; sori indefinite, following the course 
of veinlets, confluent all over the under surface at last; spores bilateral, ovoid, 
broadly winged all around.

Our fern, which is found to be abundant in shaded ravines in the Island 
Hongkong, is closely related to B. Quoyana (Gaud.) Ching from Malaya, differs 
chiefly in its not coadunate but free apical pinna and rotundo-cuneate base of the 
lateral pinne. ;
