Fronds ca. 1 cm apart; lamina usually linear, 15-20 × 0.4-0.6(-1) cm, widest at middle, leathery or thinly leathery, sparsely scaly; venation hidden. Sori restricted to distal 1/2 or narrowed apex, medial, orbicular, ca. 2.5 mm in diam., usually protruding beyond margin to give moniliform appearance; paraphyses iridescent, orbicular, 0.3-0.5 mm in diam., with square transparent lumina.

● On trunks; (600-)1600-3100 m. Taiwan.

A distinct species with laminae mostly less than 0.5 cm wide and moniliform due to the projecting beadlike sori, rarely laminae more than 0.5 cm wide and sori not beyond leaf margin. The most useful character is the transparent paraphysis with square lumina.
