贡山假毛蕨 gong shan jia mao jue

Plants to 1 m tall. Rhizomes not seen. Stipes ca. 23 cm, bases brownish, distally stramineous, glabrous; laminae broadly lanceolate, ca. 70 × 30 cm, proximal 3 pairs of pinnae reduced and hastate, pinnate-pinnatifid, pinnatifid-acuminate at apices; middle normal pinnae ca. 20 pairs, alternate, spreading, lanceolate, 15-17 × 2.5-3 cm, bases truncate, sessile, pinnatifid, apices acuminate; segments more than 25 pairs, broadly ligulate, 11-14 × 5-6 mm, rounded-obtuse at apices; proximal pair of segments (particularly acroscopic one) clearly elongated, slightly lobed along margins. Veins evident abaxially, raised on both sides, 10-12 pairs of veinlets per segment, acroscopic veinlet of basal pair reaching bottom of sinus, basiscopic one reaching margin above sinus. Laminae greenish when dry, herbaceous, abaxially with dense acicular hairs along rachises, costae, veins, and intercostal areas and mixed glands; adaxially densely setaceous along costal grooves, appressed shortly hairy on costules, glabrous on intercostal areas. Sori orbicular, attached above middle of veinlets, 7 or 8 pairs per segment; indusia orbicular-reniform, membranous, brown, with 1 or 2 short hairs, persistent.

● Margins of evergreen broad-leaved forests on slopes; ca. 1400 m. Yunnan (Gongshan).

Pseudocyclosorus gongshanensis is similar to P. pseudorepens but differs in the proximal pair of segments on each pinna much larger than more distal ones, lobed along margins, and the sori attached on middle of veinlets.
