This new species is dedicated to Charles E. DeVol (1903– 1989), a kind taxonomist who studied Taiwanese Selaginellaceae (DeVol &amp; Chen 1966) and was an editor for the Flora of Taiwan, 1st ed.</p><p>Annual prostrate lycophyte, very small, without erect or ascending stems. Stems widely branching with main segments 1– 3 cm long, 2– 2.5 mm wide (rarely broader than 3 mm) across microphylls, decumbent or creeping. Rhizophores present along basal branches. Trophophylls conspicuously dimorphic, arranged in 4 ranks (2 dorsal and 2 ventral), vein single, prominent on the ventral side, usually not reaching the apex, margin with 1–2 rows of specialized, elongated cells; axillary trophophylls present at branch forks, inserted at the ventral side of the stem, broadly ovate to elliptic, sparsely serrulate along margin; ventral (lateral) trophophylls broadly ovate or broadly oblong, rarely ovate, 1–1.3 mm long, 0.7– 0.9 mm wide, rounded or somewhat cordate at base, rounded or broadly acute at apex, usually sparsely serrulate along margin but sometime</p><p>1 Endemic Species Research Institute, 1 Ming-Sheng E.

Strobili terminal to branches, complanate, 3 –10 mm long, 2.5 –3 mm wide; sporangia on the ventral side only, megasporangia at the basal parts and microsporangia more apically; dorsal sporophylls significantly larger than ventral ones; dorsal sporophylls widely spreading, broadly falcate, 1–1.3 mm long, 0.5– 0.7 mm wide, sparsely serrulate along margin, acute to rounded at apex, the single vein bearing a keel-like wing along its basal half on the ventrally facing adaxial side, margin of the wing toothed; ventral sporophylls pointing forward, shovel-like, ovate or broadly lanceolate, vein prominent on the ventrally facing abaxial side, 0.7–0.9 mm long, 0.4 –0.5 mm wide, serrulate along the margin apically but toothed nearer the base, acuminate or acute, rounded at the base.</p><p>Distribution &amp; IUCN Red List category — This new species is endemic to Taiwan. Four populations were found in central and southern Taiwan (Map 1). The occupied area in each distribution site was estimated less than 400 m 2. Weed control via weeding and/or burning by human was often implemented in the distribution sites. These disturbances have changed illumination conditions and even directly damaged plants of this spike-moss.As there are less than five localities, with an area of occupancy of c. 10 km 2, and a decline in quality of habitat owing to human disturbance, the conservation status of this species is considered to be Endangered (EN B2ab(iii)), according to IUCN Red List Categories and Criteria (IUCN 2001).</p><p>Habitat &amp; Ecology — The species grows in the region with seasonal drought. Its habitat is the moist rocky slope with some shade in the wet season. The plants die during the dry season and new plantlets sprout at the beginning of the wet season.</p><p>Additional specimens.

The new species has sporangia only on the ventral side of strobili, unlike in other Taiwanese species. The dorsal sporophylls provide a laminal flap or pteryx (Quansah &amp; Thomas 1985) that probably helps protect the sporangia.</p><p>Selaginella devolii is similar to S. kouytcheensis H.Lév. of China (Wang 1990, Wang &amp; Wang 2001) in its minute size, complanate strobili with dorsal sporophylls larger than ventral ones, and serrulate trophophyll margins, but the latter has larger trophophylls (1.5– 2 by 0.6 –1 mm for ventral; 0.8 –1 by 0.4 – 0.6 mm for dorsal), oblong ventral trophophylls, and serrulate ventral sporophophyll margins. In addition, the new species has dorsal sporophylls with a keel-like wing along part of the single vein. In Taiwan, S. devolii most resembles young sporophytes of S. leptophylla Baker. However, the latter has oblong ventral trophophylls and lanceolate dorsal ones that easily distinguish it. Selaginella ciliaris (Retz.) Spring, which usually grows together with this new species, has trophophylls and sporophylls with a ciliate margin that makes it different.</p></div>	https://treatment.plazi.org/id/5330E5780A4D3515FFD61102FE38FA73	Public Domain	No known copyright restrictions apply.
