may also be grown in 5-inch pots. N. acuminata (davallioides) is 

 somewhat coarse in growth. It needs careful handling while the 

 fertile fronds are developing. Moderate sized specimens do not show 

 this plant at its best, as it is the very long, fertile fronds on plants 

 several feet across which make it attractive. The plant known as 

 N. davallioides furcans is a crested form. When planted out on 

 benches it gives oft plants from runners in the same manner as the 

 Boston Fern, but not so plentifully. Old specimens may be divided, 

 and the pieces put thickly together on a bench, in leafmold and sand, 

 to make a little growth before potting. N. biserrata {acuta) is a 

 stout growing and distinct species; the fronds are sometimes 16 

 inches broad and from 2 to 4 feet long. It makes but few fronds 

 when compared with some of the others. It must have abundant 

 root room. 



Propagation. Many of the sorts are propagated by division 

 of old plants; others produce runners which root and produce young
