Rhizome thick, creeping, clothed at the growing tip in blackish, rigid entire, 
lanceolate scales; frond approximate, stipe 20-30 cm long, dark straminous, scaly 
near the base, sparcely setose hairy throughout, lamina deltoid-pentagonous; lateral 
pinnz 1-2-jugate under the distinct, petiolate, pinnatifid large terminal pinna with 
cuneate base, the basal ones much the largest, petiolate, trifoliolate or trilobed 
with central lobe much the largest to 16 em long, 12 cm broad, more or less lobed 
under the acuminate entire apex, base subrounded or cordate, the second pinne 
(if there any) oblong-lanceolate, acuminate, lobato-sinuate, base oblique and slight- 
ly adnate; texture herbaceous, underside rather copiously setose hairy, upperside 
glabrous except costa and rachis clothed in short reddish hairs; venation distinct, 
anastomosing with or without included veinlets in areole; sori large, rounded, 
compital, scattered or uniseriate in the lobes, leaving a broad sterile Space along 
costa, indusium rotundo-reniform, thick, fallen off at last. 
Besides those cited in my previous paper, additional specimens have since 
been noted as follows: 
Hainan: Hung Mo Mt., W. 7. Tsang 18082; Tai Hang, Lin Hwa Shan, W. 
T. Tsang 15850; Top of Dome, Five Finger Mt., W. Y. Chun 6867 in herb. Univ.

This is a very common fern in South China and particularly, the Island Hong- 
kong, and closely related to 1’. variolosa (Wall.) from which it differs by the charac- 
ters as already noted in my previous paper.
