Rhizome short, erect or oblique, densely scaly; scales dark rufo-brown, linear- 
lanceolate, subulate towards apex; fronds subceespitose, stipe 10-20 cm long, dark 
straminous, sparcely scaly throughout rachis, lamina 12-28 cm long, 7-11 cm broad, 
simple pinnate with distinct end-pinna; pinnz 5-12-jugate, long-petiolate, the lower 
ones much the largest, gradually diminished towards apex, rhomboid with attenu- 
ate base and gradually acuminate towards apex, the lower ones often 1-2-lobed, 
margin erose-dentate; texture coriaceous, glabrous on both sides; venation distinctly 
canaliculated on both sides; sori linear, oblique, indusiwm of the same shape, 
brown, thick, entire, the lower ones open towards each other.

This is another of the distinct but little known Chinese species by Hance, 
but, unfortunately, his name, 4. comptum, has to become invalidated by Kunze. 
Our fern is closely related to A. dimidiatum Sw. of tropical America, to which it 
was referred as a variety by Baker, as identical by Christ and others, but differs 
in long-petiolate pinnee with erose-dentate (not lacerate) margin. The type from 
Kweichow has lateral pinne tend to lobato-pinnate; the same form is also seen 
from Kwangtung.
