Hab. Manchuria, C. Wilford, 1859, n. 1094. 



This new species of the Physematium-growp of Woodsia, 

 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.
