Rhizome wiry, wide-creeping generally on the trunk of trees, greenish, sparcely 
scaly; scales thin, clathrate, light-brown, entire, subulate from a broad, lacerato- 
fimbriate base; frond dimorphous, the sterile mostly orbicular with rounded or 
subcordate base (f. typica), or ovateor broadly obovate with shortly cuneate base (var. 
obovatum), 5-15 mm broad, surfaces naked or with a few brown, ovate, clathrate scales; 
texture carnose (in fully grown leaves), or submembranaceous (when young), color pale 
green, but obscurely brown or even blackish when dried; venation not distinct, rather 
regularly reticulate and looped some way below the thin, plane margin, meshes 
provided each with one simple, recurrent, clavate veinlet; fertile frond strongly contracted, 
ligulate, 2-3 mm broad, 3-4 cm long including the short stipe; sori linear, medial, densely 
scaly, laterally broadened at maturity; spores subreniform. pellucide, smooth.

Type from Japan, first collected by Thunberg and named Pteris piloselloides by 
himself. A very variable fern as to the shape of sterile leaves; in some extreme forms it 
approaches L. drymoglossoides (Baker) so closely that it can be distinguished from tho 
latter species with difficulty, as already pointed out by Dr. Christensen in his recent 
critical work on the genus. In typical form, the sterile fronds orbicular, rounded or 
cordate at base; in var obovatum (Harr.), they are obovate or ovate, shortly cuneate at 
base on rather long petioles. Drymoglosswm Nobukoanum Makino, Journ. Jap. Bot. 7: 8 
(1931), now to be called LEMMAPHYLLUM NOBUKOANUM (Makino) Ching, comb. nov. 
from Formosa seems to be specifically distinct from var. obovatum by slender, small, 
spothulate sterile fronds and almost linear fertile ones on long, wiry stipes (cf. Ogata, Ic. 
Fil. Jap. pl. 165. 1931).
