9F5E193899AA5420A83C8736C142C4DD.taxon	description	Description. Only one bunch of tubers are preserved on the specimen, tubers are ovate in shape, three tubers of equal size are arranged in one row (Fig. 2 A-B). The length and width of the tubers are ~ 0.9 to 1.2 cm and 0.6 to 0.8 cm, respectively. Two to three longitudinal ridges are present on the surface of each tuber (Fig. 2 A-B). The tip of the tuber is mucronate (Fig. 2 A-B). These characters fit well within the morphology of E. cf. pratense, a fossil species reported from the early Oligocene in the Luehe coal-mine, south-central Yunnan (Zhang et al. 2007; Linnemann et al. 2018).	en	Aung, Aye Thida, Huang, Jian, Do, Truong Van, Song, Ai, Liu, Jia, Zhou, Zhe-Kun, Su, Tao (2020): Three new fossil records of Equisetum (Equisetaceae) from the Neogene of south-western China and northern Vietnam.

8AF9194F9E0C55B4A5EA87D79B3ACA15.taxon	diagnosis	Diagnosis. Rhizomes with internodes and nodes, node round; Four bunches of tubers arranged in a whorl on a node (Fig. 2 D); most tubers elongate in shape, with one to two tubers in each bunch (Fig. 2 C-D); longitudinal ridges on the surface of tuber; the tip of tuber mucronate (Fig. 2 F).	en	Aung, Aye Thida, Huang, Jian, Do, Truong Van, Song, Ai, Liu, Jia, Zhou, Zhe-Kun, Su, Tao (2020): Three new fossil records of Equisetum (Equisetaceae) from the Neogene of south-western China and northern Vietnam.

8AF9194F9E0C55B4A5EA87D79B3ACA15.taxon	description	Description. Rhizomes have both internodes and nodes (Fig. 2 D). The internode is ~ 0.2 - 0.3 cm in width, the length could not be observed, three longitudinal ridges are on the surface of the internode (Fig. 2 D). The node is round and ~ 0.2 cm in diameter (Fig. 2 D). Four bunches of tubers attach to one node and arrange in a whorl (Fig. 2 D). Only one tuber is preserved on each bunch, but it is likely that there are more than one tuber on each bunch (Fig. 2 E-F). Most tubers are elongate (Fig. 2 D); few are elliptical (Fig. 2 F), being ~ 0.8 to 3.0 cm long and 0.4 to 1.0 cm wide. Two to four ridges are on the surface of each tuber (Fig. 2 D). The tip of tuber is mucronate (Fig. 2 F).	en	Aung, Aye Thida, Huang, Jian, Do, Truong Van, Song, Ai, Liu, Jia, Zhou, Zhe-Kun, Su, Tao (2020): Three new fossil records of Equisetum (Equisetaceae) from the Neogene of south-western China and northern Vietnam.
