OLEANDRA WHANGII Ching, Bull. Dept. Biol. Coll. Sci. Sun Yatsen Univ. No. 6! 23 (1933); 
C. Chr. Ind. Fil. Suppl. TIT. 133 (19384). 
Oleandra musifolia Wu (non Bl. 1828), 1. c. No. 3: t. 37 (1932). 
Rhizome wide-creeping along the rock surface, densely scaly; scales rusty brown, 
lanceolate, thick, dorsally affixed, margin subscarious, densely imbricate; fronds sub- 
fasciculated, 3-4 together, stipe 1-4 cm long, pale stramnious, nitid, naked, articulated 
above base, lamina broadly linear-lanceolate, 25-35 cm long, 3-5 cm broad with almost 
parallel margin except towards both ends being slowly narrowed, margin subundulate; 
texture chartacaous, green, glabrous on both sides except the costa beneath being sparcely 
provided with brown scales and a few short articulated hairs; veins fine, but distinct, 
mostly forked from base, parallel, extending to the cartilaginous margin; sori irregular- 
ly 1-rowed some distance from costa, indusium reniform, large, brown, membranaceous, 
glabrous.

This distinct endemic species, known so far only from one single locality, differs 
from its all Chinese relatives in subfaciculated fronds on very short stipes, naked surfaces 
of lamina (or with very few short hairs along costa beneath) of broadly linear-lanceolate 
outline with nearly parallel edges, and large naked indusium at some distance from the 
costa.
