Hab. Manchuria, C, Wilford^ 1859, n. 1094. 
This new species of the PAz/^ema^z^m-group of JVoodsia, 
quite distinct from any hitherto described, was detected by 
Mr. Wilford, in a country whose Botany is deserving of a 
careful investigation, Manchuria. The involucres are of so 
delicate a texture that the pressure given in drying destroys 
their spherical form, and in that state they present the appear- 
ance of a thin membrane, but soaking in warm water restores 
them to their proper shape.
