C615EC3AB7795E4D8ED5FC47F4AC8103.taxon	diagnosis	Diagnosis. Angiopteris nodosipetiolata is morphologically quite similar to A. chingii J. M. Camus in terms of having more than one naked pulvinus on the stipe and numerous joint-like hairs on the undersides of the mature pinnae. However, the former’s pinnae are lanceolate, occurring in 4 – 6 pairs, in contrast with the elliptical pinnae of the latter, which consist of only 2 – 3 pairs. Judging from the shape of laminae, A. nodosipetiolata also closely resembles A. latipinna (Ching) Z. R. He, W. M. Chu & Christenh. and A. subrotundata (Ching) Z. R. He & Christenh. Nonetheless, these two species exhibit only one naked pulvinus on the stipe and the surfaces of their mature pinnae, apart from the mid-rib, are smooth and hairless (Table 3). The phylogenetic and genetic distance analysis also showed that A. nodosipetiolata is not the closest relative of A. latipinna, A. subrotundata or A. chingii (Figs 1, 2).	en	Wang, Ting, Yang, Tuo, Zhang, Jin-Guo, Zhang, Gui-Liang, Yao, Shi-Wei, Xiang, Jian-Ying, Yan, Yue-Hong, Chen, Hong-Feng (2024): Angiopteris nodosipetiolata (Marattiaceae), a new fern species from Yunnan, China.

C615EC3AB7795E4D8ED5FC47F4AC8103.taxon	description	Description. Plants terrestrial, 70 – 120 cm tall. Rhizomes long creeping. Stipes 40 – 70 cm long, 0.7 – 1.5 cm in diam., with 2 – 3 naked pulvini (occasionally with 1); stipe scales peltate, brown, lanceolate, margins with hair-like outgrowths, apex acuminate, cells clathrate and elongate. Laminae 35 – 50 × 25 – 30 cm; once pinnate, pinnae 4 – 6 pairs, lanceolate, ca. 15 – 20 × 3.5 – 4.5 cm, bases round-cuneate, margins coarsely dentate, apices caudate, densely covered with jointed hairs on the undersides of the mature pinnae. Veins free, simple or bifurcate, false veins absent. Sori medial, yet closer to the main vein, ranging in length from ca. 0.5 cm on the basal pinnae to ca. 1.8 cm in the middle pinnae. Exospores with forked rod-like ornamentation.	en	Wang, Ting, Yang, Tuo, Zhang, Jin-Guo, Zhang, Gui-Liang, Yao, Shi-Wei, Xiang, Jian-Ying, Yan, Yue-Hong, Chen, Hong-Feng (2024): Angiopteris nodosipetiolata (Marattiaceae), a new fern species from Yunnan, China.
