03E98798970BFFD517B6FF36FAC8FDE9.taxon	materials_examined	Type: — CHINA. Yunnan: Xishuangbanna, Mengla County, Bubeng, elev. 580 m, in soil or on rocks near streams in shaded forests, April 15 2016, Yan-Fen Chang & Hua-Feng Hong, Chang 1039 (holotype, HITBC!, isotype, KUN!). Plants 25 – 40 cm tall. Rhizomes long creeping, 2 – 3.5 mm in diameter, apex densely scaly; scales dark brown, narrowly triangular, entire; phyllopodia distinct, ca. 2 mm tall, 2 – 3 mm apart. Fronds grayish green, herbaceous; lamina onepinnate, ovate-triangular, 10 – 25 × 5 – 8 cm, widest near base, gradually narrowing toward apex, apex acute, glabrous; stipe shiny, purple to black, 10 – 25 × 0.05 – 0.15 cm, glabrous, base sparsely scaly; rachis shiny and purplish black abaxially, adaxial side grooved and with two grayish green narrow wings; pinnae almost sessile to shortly stalked with rachis color extending via the foot-stalk of the pinnae onto base part of costa abaxially, 10 – 25 pairs, alternate, spreading with basal pairs deflexed near stipe, quadrangular-trapeziform, 3 – 4.2 × 0.7 – 1.2 cm, base asymmetrical, acroscopic side truncate and parallel to rachis, subauriculate, basiscopic side attenuate-cuneate, with ca. 1 ⁄ 3 cut away, acroscopic margin serrate, teeth not retuse, pinna apex subacute. Veins forking and terminating in marginal teeth, only one or two basal basiscopic veins lacking. Sori linear, 3 – 6 mm, medial; indusia brownish, linear, membranous, entire, opening toward costa. Spore with crests. Plants triploid, likely apogamous, with chromosomes 2 n = ca. 117. Diagnosis: Hymenasplenium laterepens is similar to H. apogamum (N. Murak. & Hatan.) Nakaike. However, H. laterepens has larger triangular lamina, pinnae acute at the apex and more deeply serrated on the margin, and long creeping rhizome with thicker roots. Distribution and habitat: H. laterepens is currently known to coexist with H. apogamum in southeastern China in soil or on rocks near streams in shaded forests at elevation of 200 – 800 m.
