Rhizophores restricted to base of stem and creeping rhizomes and stolons, 2–7 cm long, slender, 0.15–0.20 mm in diam., roots much forked, nearly glabrous. Main stem branched from lower part, pinnately branched, straight, or sometimes slightly zigzag, reddish when fresh, nonarticulate, stramineous when dry, unbranched main stem 5.5–19.0 cm tall; 2.0– 3.3 mm in diam. in lower part, terete, sulcate, glabrous, with 3 vascular bundles arranged in a single row, fertile stems 2–3 times pinnately branched, main stem together with leaves 3.0– 5.7 mm wide at middle; primary leafy branches 7–9 pairs, larger ones 24–30 × 8–26 cm, usually 3 times pinnately branched, basal two adjacent primary branches on main stem 5–9 (– 15) cm apart, tertiary branches simple or forked, occasionally once pinnately branched, branchlets sparse and regular, ultimate branches along with leaves 3–7 mm wide. Leaves herbaceous. Axillary leaves symmetrical, base obtuse or slightly biauriculate, margin entire, obovate on main stem, obovate to oblong-elliptic on branches, those on main stem obviously larger than those on branches, 1.4–3.4 × 0.7–2.5 mm. Dorsal leaves asymmetrical, those on branches approximate to imbricate, overlapping at leaf apex, falcate-oblong, sometimes nearly falcate-obovate; dorsal leaves on main stem larger than those on branches, 0.8–3.5 (– 4.0) × 0.4–1.8 mm, not carinate, base obliquely subcordate, slightly uniauriculate at basiscopic side, margin entire, apex obtusely cuspidate. Ventral leaves asymmetrical, spreading or slightly ascending, those on main stem distant below apex, oblong-ovate, and those on branches distant to overlapping, oblong-ovate to falcate-oblong; ventral leaves on main stem obviously larger than those on branches, 2.0–4.8 × 0.8–2.6 mm, margin entire, apex obtuse; acroscopic base rounded, not overlapping stem and branches; basiscopic base rounded or rounded truncate, sometimes slightly enlarged and subauriculate, not or slightly overlapping stem and branches. Strobili solitary, terminal, compact, tetragonal, 2–6 (– 8) × 1.2–1.6 (– 2.6) mm; sporophylls uniform, not white-margined, occasionally with 1 cell wide, not obviously membranous margin, broadly ovate or suborbicular, carinate, margin entire, base shallowly cordate, apex acute or cuspidate; microsporophyll up to 1.4 × 1.2 mm or more, megasporophylls often larger, up to 1.8 × 1.6 mm, distributed in middle on lower side of strobilus; microsporangia semicircular, brown, 0.7–0.8 × 0.5–0.6 mm, cells regular, megasporangia suborbicular, brownish green or pale green, 1.0– 1.2 mm in diam ..</p><p>Spore morphology.</p><p>Megaspores white or yellowish white, four per sporangium, orbicular or suborbicular in polar view, oblate spheroid in equatorial view, 320–400 μm in polar axis and (290 –) 400–600 μm in equatorial axis; prominent laesurae extend 5 / 9–2 / 3 of the distance to the equator in polar view, both proximal and laesurae surfaces covered with granulate and verrucate elements, other surfaces with abundant, shot baculate and discrete or coalescent tubercles (Fig. 1 E). Microspores are yellowish orange, suborbicular in polar view, 22–27 μm in polar axis, perispores clothed with long, curved lamellate ornamentations (Fig. 1 G).</p><p>Distribution and habitat.</p><p>Selaginella magna was found in at least seven localities within China’s mid-subtropical zone at similar latitudes, with elevations ranging from 600 to 1076 meters. These localities include northeastern Guangxi, northwest Guangdong, central Fujian, southwest Hunan, and southwest Jiangxi (Fig. 3). Populations in Fujian and Guangxi inhabit valley lowlands, while one population in Hunan thrived in a bamboo-broadleaved mixed forest.</p><p>Conservation assessments and ecology.</p><p>At least nine populations were found in China, two of which were separated by only a few hundred meters. The combined range of these populations extends roughly 720 kilometers east-west and 250 kilometers north-south, encompassing a total area of approximately 82,600 square kilometers, as defined by the outermost occurrence points. The plant typically forms dense, compact colonies through localized vegetative growth of its horizontally spreading rhizomes. Selaginella magna may occur in other areas. As its broader distribution has not yet been fully investigated, we recommend that it be classified as Data Deficient (DD) under the IUCN Red List criteria (IUCN 2024).</p><p>Etymology.</p><p>The epithet of the new species is derived from the Latin “ magna ”, meaning great or large.</p><p>Chinese name.</p><p>硕大卷柏 (shuò dà juăn băi).</p><p>Paratypes.</p><p>The same place as the holotype, 31 December 2020, She-Lang Jin &amp; Bin Chen JSL 7741 (CSH!) · ibid., 8 July 2021, She-Lang Jin &amp; Bin Chen JSL 8163 (CSH!) .
