Abstract
Hymenasplenium wusugongii Li Bing Zhang, W.B. Liao & K.W. Xu is newly recorded from Jinghong City, Yunnan Province, China. This recently described species was previously known only from Luang Prabang District in northern Laos. Hymenasplenium wusugongii is characterized by a narrowly ovate to narrowly deltoid lamina, up to 12 cm wide, with a 1-pinnate structure, an acuminate apex, and long-stalked pinnae that lack 1–2 basal basiscopic veins, making it morphologically distinct within the genus Hymenasplenium. This paper provides a detailed description of its morphological characters, along with in-situ photographs and illustrations. Voucher specimens have been deposited in the Shanghai Chenshan Herbarium (CSH) and Herbarium of Guangxi Institute of Botany (IBK).
