POLY PODIACEAE 
ASPLENIUM ADNATUM Copeland, Phil. Journ. Sci. Bot. 3: 284 (1909); C. Chr. Ind. 
Fil. Suppl. ro (1906-12).

long, about 3 cm broad, linear-lanceolate, simple pinnate below pinnatifid apex, rachis 
green, unisulcate above, sparcely scaly beneath; pinnae broadly adnate, the basal ones 
somewhat shortened, rachis wingless, those above the middle are connected by a narrow 
wing along the rachis, oblong, subacute, patent, margin obscurely dentate above the

Kwangtung: Tai-mo Shan, opposite Hongkong, C. G. Matthew (type), November 
7» 1907. 
An unique species, characterized by narrowly lanceolate, simple pinnate leaves 
with short, adnate pinnae and dense, black, fibrillose scales on the stipe and rachis 
beneath. However, it may possibly prove to be a young form of the variable Aspleni- 
um crinicaule Hance, common in the locality.
