Rhizome short, erect; scales light brown, thin, ovate-lanceolate, acuminate, 
clothing the apex; fronds ceespitose, stipe short, terete, 2-5 cm long, glossy, strami- 
nous, sparcely scaly, lamina lanceolate, 10-80 cm long, 2-4cm broad, or even breader, 
membranaceous, clear light green, glabrous on both sides, deeply bipinnatifid under 
pinnatifid acuminate apex, rachis glabrous, deeply sulcate above; pinne 15-40- 
jugate, oblique, sessile, the lower ones much abbreviated and opposite, the upper 
ones alternate, 1-3 cm long, oblong-obtuse, base truncate, deeply pinnatifid; seg- 
ments 5-8-jugate, oblique, oblong-ovate, obtuse, entire or slightly sinuate; veins pin- 
nate, 2-3-jugate, veinlets fine, oblique, fail short of the margin with enlarged apex; 
sort large, on the anterior basal veinlets of each segment, below the sinus, indusium 
large, globose, gray, thin membranaceous, opening with a toothed edge of the con- 
tracted mouth at the top.

One of the most distinct species of the subgenus Physematium, characterized 
by light green, membranaceous glabrous leaves and large, membranaceous sac-like 
indusium opening by the contracted mouth at the top. Its occurence in North 
China is said to be by no means common. W. insularis Hance, based upon Clarke’s 
plant from Sagalien, only represents a small form of this species, evidently grow- 
ing in a dry situation.
