POLYSTICHUM CONSIMILE Ching, sp. nov. 
Species configuratione Polystichi hecatopteridi Diels proxime similis, differt stipitibus rachibusque 
squamis ovatis ab initio sparsis demun subevanescentibus conspersis, pinnis omnibus lateralibus . deflexo- 
recurvatis, latioribus, basi anteriore paulo auriculatis, marginibus dentibus aristatis sparsis et brevioribus 
praeditis. 
Rhizome short, erect, densely radicose, together with stipes at first sparsely clothed in dark-brown, 
ovate, acuminate scales, later become nearly naked; fronds caespitose, many together, stipe 10-12 cm long, 
of a dead-stramineous color, lamina 20-28 cm long, 3 cm broad, linear-lanceolate, acuminate, base slightly 
narrowed, pinnate; pinnae 30-35 pairs, pectinately imbricate, petiolulate, deflexo-recurvate, 1.5 cm long, 7-8 
mm broad at the base, subrhombic-triangular, apex short-acute or bluntish, base unequal, cut straight below, 
truncate above and slightly auricled, margin sparsely aristate-serrate with long spreading spines, the lowest 
pinnae smaller, less than 1 cm long, deflexed; texture herbaceous, dry dark brown, glabrous on both sides; 
veins indistinct, forked, but the anterior basal one pinnate; sori small, intramarginal, about 7-9 on the upper 
side, 1-3 on the lower side below the apex, terminating anterior forking of each lateral vein, indusium entire.

A distinct species of the group of P. deltodon (Bak.) Diels with elongate glabrous fronds above the base 
of the stipe, of a herbaceous texture and the deflexly recurvate, pectinately imbricate pinnae with remote 
long spiny teeth,
