OLEANDRA WALLICHII (Hooker) Presl 
POLYPODIACEAE 
OLEANDRA WALLICHII (Hooker) Presl, Tent. Pterid. 78 (1836); Hk. et Bak. Syn. Fil. 303 
(1868); C. Chr. Ind. Fil. 467 (1906). 
Aspidium Wallichii Hooker, Exot. Fl. 1: t. 5 (1823); Bedd. Ferns Brit. Ind. t. 265 (1868). 
Neuronia asplenioides Don, Prod. Fl. Nepal. 6 (1825). 
Oleandra Wallichii var. lepidota Christ, Bull. Acad. Géogr. Bot. (1906) 140. 
Rhizome horizontally creeping, densely shaggy scaly; scales ferruginous, spreading, 
linear-subulate, fimbriate, dorsally affixed; stipe distant or approximate, I.5-5, cm long, 
ferruginously hairy, jointed close to the base, so that the very short, lower articulation is 
quite concealed among the scales; lamina 15-30 cm long, 2-3.5 cm broad, apex suddenly and 
sharply acuminate; base subrounded or rotundo-cuneate, both edges parallel, somewhat 
wavy; texture papyraceo-herbaceous, midrib densely scaly beneath, rather densely 
hairy on veins on both sides and densely ciliate along the edges; venation distinct, veins 
patent, fine, closely parallel, generally forked from near, or above the base; sori rather 
irregularly uniseriate on each side, close and parallel to the midrib; indusium orbicular- 
reniform, hispidato-ciliate, attached by a deep sinus and opening outwardly.

Birma, Sikkim-Himalayas, Malyan Peninsula. 
A well marked species of the genus, common in the Sikkim-Himalayas and the 
southwestern part of Yunnan. In habit, it resembles O. Cumingit J. Sm. from the 
Philippines and South China, which differs from the present species in rhizome scales 
being imbricatingly adpressed, usually much higher articulation of the stipe and 
leaf-margin not densely ciliate.
