LEMMAPHYLLUM ADNASCENS Ching, Bull. Fan Mem. Inst. Biol. 4: ror (1933). 
Rhizome slender, wide-creeping, x1 mm_ thick, sparcely scaly; scales ovate, 
acuminate, fuscous, coarsely clathrate, denticulate: frond distant, strongly dimorphous, 
the sterile 8-11 cm long, below 2 cm broad, ligulate or oblanceolate-ligulate, obtuse, 
gradually attenuate to a short stipe; texture thickly carnose, pale green, scaly on both 
surfaces; venation completely hidden; fertile frond much contracted, narrowly linear- 
elongate, to 10 cm or longer, below x cm broad, underside’ densely scaly; sori large, 
oblong-ovate, filling up the space between the midrib and margin, which latter 
sometimes appears wavy, due to the protruding sori.

A remarlable fern and perhaps the largest of the genus, not expected at all at 
such a late date from a region, where the botanical éxploration has supposedly been 
carried out intensively over half a century. Evidently a rare fern in the locality, only 
two good specimens being collected. Its affinity to L. drymoglossoides (Baker) is clear 
enough, differs chiefly in much larger size, thicker and much harder texture, densely 
scaly under surface, in rhizome scales of different outline and sori being of much 
larger size, completely filling up the space between the midrib and margin.
