CYRTOMIDICTYUM CONJUNCTUM Ching in Acta Phytotax. Sinica 6: 263. t. 52. 1957. 
Polystichum conjunctum Ching in herb. 
Rhizome short, erect, densely radicose; fronds Caespitose, spreading or nodding, stipe 15-20 cm long, 
clothed throughout in dense, large, brown, ovate-acuminate, ciliate scales with a long cauda, the fertile, 
lamina 15-20 cm long or longer, 4 cm broad, lanceolate, not narrowed at base, gradually acuminate, simply 
pinnate; pinnae about 20 pairs, contiguous, patent, the lower 7-10 pairs free, petiolulate, the upper ones more 
or less adnate under the pinnatifid apical part, the basal pair as long as, or slightly longer than those next 
above, 2-2.3 cm long, 1 cm broad, ovate-oblong, acute, not mucronate, base subequal, round-cunéate below, 
rather bluntly auricled and truncate above, margin entire, or more or less repando-undulate; texture sub- 
coriaceous, dry brown, rachis copiously scaly, naked above and copiously clothed in minute, appressed, ovate- 
caudate, ciliate scales on the under side of pinnae; veins obscure, free or occasionally joint in the lower part, 
in pinnate groups, or forked towards apex, of which the anterior basal veinlet stops short far below the 
margin; sori small, rounded, medial and uniseriate on each side of costa, or biseriate near the. base above, 
dorsal on the anterior basal veinlet of each group. The sterile fronds similar to the fertile with less pairs 
of pinnae separated from each other by broad sinuses, axis prolongated at apex into a long whip-like 
densely ‘scaly stolon. gelas ce ; He

A distinct local species, closely related to C. basipinnatum (Baker) Ching, differing in the pinnate 
fronds having free pinnae in the lower part, which are slightly auricled on the upper side of the base.
