W. (Physematium) manchuriensis — Phy-se-mat'-i-um ; man-chu'-ri- 

 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. 



W. (Physematium) mollis — Phy-se-mat'-i-um ; mol'-lis (soft), /. Smith. 

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

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

 Minas-Geraes (Brazil), and the

 Gardens, Kew, in 1841. Its 

 fronds, which are spear-shaped 

 and pinnate, are generally 

 densely clothed, especially be- 

 neath, with soft, jointed hairs ; 

 their oblong-spear-shaped leaflets 

 are somewhat blunt, stalkless, 

 and deeply cleft into oblong or 

 oval, stalkless pinnules (leafits), 

 rounded at the summit and 

 notched on the margins. —
