 en'-sis (Manchurian). 

 A species of medium dimensions, native of Manchuria and Japan. Its 

 oblong-spear-shaped, sharp-pointed fronds, Gin. to Sin. long, are once divided 

 to the midrib into stalkless leaflets lin. or more in length, of a thin texture, 

 and deeply cleft into oblique, egg-shaped, blunt, entire or slightly wavy lobes, 

 each of which bears one spore mass only. — Hooker, Second Century of 

 Ferns, t. 98.

According to Lowe, this species, also known in gardens under the names 

 of W. fragilis and W. guatemalensis, and native of Mexico, Guatemala,

 fronds, which are spear-shaped
