POLYPODIACEAE 
ELAPHOGLOSSUM MCCLURE! Ching, Sinensia I: 55 (1930). 
Rhizome short, oblique, densely scaly; scales brown, broadly lanceolate, acuminate, 
margin sparcely fimbriate, texture rather thick: frond subcaespitose, several together, 
dimorphous, the fertile ones somewhat longer than the sterile, stipe of sterile frond 4 
cm long, that of the fertile over 10 cm long, straminous, densely scaly; lamina of sterile 
rond 10-14 cm long, to 3 cm broad, lanceolate-ligulate, apex obtuse, base shortly at- 
ftenuate; texture thick coriaceous, color pale green, underside rather densely clothed with 
brown, appressed, branched _ hairs, upperside naked; margin plane, narrowly hyaline, 
midrib broadened, slightly raise above; veins completely hidden; fertile lamina to 10 cm 
long, 1.5 cm broad, lanceolate, apex acute, margin narrowly reflexed; sori obscure brown, 
dense, covering the entire underside except the midrib; spores opaque, ovoid, coarsely

Hainan: Hung Mo Tung, F. A. McClure 18257, August 22, 1929, summit of highest 
peak, on mossy trunk of forest tree, 6,000 ft. alt.; on route from Dung Ka to Win Fa Shi, 
C. L. Tso & N.K. Chun 43729, August 26, 1932, on rocks in thickets, 1,700 ft. alt. 
This is closely related to E. austro-sinicum Matthew et Christ from the mainland 
(Kwangtung), differs in much smaller size, rigid texture, ligulate sterile frond with 
obtuse apex and short-attenuate base provided with longer and thinner stipe, and fertile 
frond being longer than the sterile.
