It differs from all other cyrtomidictyoid species by rarely exhibiting pinnatifid laminae, which are confined in a few fronds bearing a whip-like apex at the rachis tip. When pinnatifid laminae are present, all segments are exclusively rounded. It further differs in having sori irregularly scattered along both sides of the rachis and distinctly thick, leathery laminae (Figure 3, Table 2).</p><p>Plants 30–50 cm tall, evergreen. Rhizomes short, erect, scaly at apex; scales 1–3 mm long, 0.5–2 mm wide at base, reddish-brown, ciliate at margins. Fronds tufted, linear-lanceolate; fertile and sterile fronds similar if rachis without a flagelliform tip, 25–50 cm long, mostly simple; lamina 20–30 × 2–3 cm with entire or repand to undulate margins; stipes 5–20 cm long, covered with same scales as on rhizome; fronds 35–55 cm long if rachis prolonged into a flagelliform tip, 5–25 cm long and often gemmiferous at apex, sterile; lamina 10–20 × 1.5–2.5 cm, sometimes pinnatifid with rounded segments at apex, segments 0.9–1.2 cm wide; adaxial surface sparsely covered with pale brown, fibrillose scales, scales 3–5 mm long, abaxial surface with attached scales, scales 1–1.5 mm long, 0.5–0.8 mm wide at base, ovate-lanceolate, translucent, membranous, long fimbriate at margin. Venation pinnate; midrib indistinct; veinlets 7–8 pairs, forked, basal pair not reaching edges. Sori scattered along both sides of rachis, irregularly distributed; indusia absent.</p><p>Ecology: — Polystichum ensiforme is observed growing on rocks by streamside, near small waterfalls in subtropical broadleaf forests at elevations between 200– 600 m.</p><p>Geographical distribution:— Polystichum ensiforme is endemic to China and currently only found in Guangxi (Guilin, Yangshuo, Rongxian) and Guangdong (Ruyuan, Yangchun, Zhaoqing, Jiangmen) (Figure 4).</p><p>Etymology: —The species epithet is derived from the Latin, ensiform (sword-shaped), referring to sword-shaped fronds of the new species.</p><p>Vernacular name:—剑叶ª叶nfi (jiàn yè biān yè ěr jué)</p><p>Additional specimens examined:— CHINA.

It was identified as " Cyrtomidictyum intergrifolium Ching et S.H.Wu " on 15 February 1982, but this name was never validly published and should be treated as a nomen nudum (Latin for 'naked name').</p></div>	https://treatment.plazi.org/id/039187B1FFA0FFF8F4EFFA70CB2CFEFB	Public Domain	No known copyright restrictions apply.
