PHLEBODIUM. 



A genus of Ferns divided from Polypo- 

 dium by the late Dr. E. Brown. They 

 may be distinguished by the situation of 

 the sori, which are placed distinctly in 

 rows between the midrib and the margin, 

 and by the veins being irregularly branched 

 and very conspicuous.

 a noble beautiful Fern it is. Fronds pin-

 Spore-masses very prominent, and of a

 Easily increased by dividing-off pieces 

 with fronds attached of the thick creeping 

 rootstock. 



P. GLAUCUM (Glaucous), Fig. 50. This
