Phymatosorus hainanensis (Noot.) S. G. Lu in Bul. Nat. Mus. Nat. Sci. TaiWan. ——Microsorum hainanense Noot. in Blumea 42 (2): 325-327. Pl. 3. F. 20-21. 1997.
附生植物。根状茎横走,粗约6-10毫米,肉质,密被鳞片;鳞片卵圆形或近圆形,直径3-4毫米,盾状着生,暗褐色,边缘近全缘或不整齐。叶远生;叶柄长约20-30厘米,禾秆色或淡栗色,光滑无毛;叶片卵状长圆形,羽状深裂,长约30-40厘米,宽约15-20厘米,基部楔形;裂片约2-5对,长约10-15厘米,宽约2-3厘米,顶端渐尖或钝圆,边缘全缘并加厚。叶轴的翅几乎与裂片等宽。中脉明显,在叶两面隆起,无侧脉,小脉网状,具顶端囊状的内藏小脉。叶革质,两面光滑无毛,背面疏被细小的黑色鳞片。孢子囊群圆形,在中脉两侧各1行,略靠近中脉着生,在叶背面略凹陷,在叶表面突起。
产海南 (琼中、海口、五指山、尖峰岭、吊罗山、南高岭) 。附生树干上,海拔20-900米。越南和印度也有分布。模式标本采自海南尖峰岭。

Microsorum hainanense Nooteboom, Blumea 42: 325. 1997.
Rhizome 6-10 mm in diam., sparsely to densely scaly; scales dark brown, orbicular, ca. 4 × 4 mm, peltate, clathrate, margin irregularly obscurely toothed. Stipe straw-colored, 20-30 cm, glabrous. Lamina pinnatifid, 30-40 × 15-20 cm, or 3-lobed, base broadly cuneate, rachis with wings ± as wide as lobes; lateral lobes usually 2-5 pairs, lanceolate, 10-15 × 2-3 cm, leathery, abaxially with very sparse and very small black scales, adaxially glabrous, margin entire, apex acute or obtuse; midrib raised on both surfaces, without lateral veins, areoles with included veinlets. Sori orbicular, large, in 1 row on either side of costa, slightly nearer to midrib, abaxially sunken and adaxially raised.
Forests, on tree trunks or rocks; sea level to 900 m. Hainan [India, Vietnam].
