青城假毛蕨 qing cheng jia mao jue

Plants to 1.4 m tall. Rhizomes creeping, woody, firm, dark brown, sparsely scaly; scales lanceolate, deep brown, fragile and easily deciduous. Fronds remote; stipes 32-37 cm, bases dark brown, distally stramineous, glabrous; laminae lanceolate, ca. 100 × 30 cm, abruptly narrowed at bases, pinnate-pinnatifid, pinnatifid-acuminate at apices; proximal 3-6 pairs of pinnae reduced and hastate; middle normal pinnae ca. 30 pairs, proximal ones subopposite, distal ones alternate, sessile, narrowly lanceolate, 12-19 × ca. 2.5 cm, truncate at bases, pinnatifid, pinnatifid-acuminate at apices; segments ca. 37 pairs, 8-10 × ca. 3 mm, entire, obtuse-pointed at apices. Veins evident, costules raised on both sides, ca. 12 pairs of veinlets per segment, proximal pair arising above base of costules, acroscopic veinlet reaching bottom of sinus, basiscopic one reaching margin above sinus. Laminae dark green when dry, papery; abaxially with long acicular hairs along rachises, sparsely shortly hairy along costae and veins, densely shortly hairy on intercostal areas, adaxially with dense appressed setae along costal grooves, with 1 or more setae along veins and glabrous on intercostal areas. Sori orbicular, attached on middle of veinlets; indusia orbicular-reniform, brown, thick, glabrous, persistent.

● Forests on slopes, wet shaded forests by streams. Guangxi (Longsheng), Sichuan (Guanxian, Qingchengshan).

Pseudocyclosorus qingchengensis is similar to P. esquirolii in laminar outline but differs by the proximal pair of segments on larger pinnae clearly elongate, proximal pair of veinlets arising from above base of costules, and laminae with dense short hairs on intercostal areas abaxially.
