CULTIVATION IN HOTHOUSES. 
6 7 
pinnae alternate, crowded, eared, one hundred pairs or 
upwards on each frond; veins forked; sori circular; 
involucres kidney-shaped. A Brazilian and West Indian 
species. 
Nephrolepis Davalloides . Hare’s-foot Nephrolepis. 
Fronds pinnate, at first upright, then arching, 5 feet 
long, they bend down below the margin of the pot; the 
sterile leaflets are broader than the fertile ones. We 
have it from the Malayan Archipelago. 
Diplazium is a genus nearly related to Asplenium , 
but differing in having the sori in pairs. The name is 
taken from diplazo , to double . 
Diplazium acuminatum . Tapering Diplazium . Fronds 
pinnate, smooth, shining, 18 inches long. A native of 
Ceylon. 
Diplazium arborescens. Tree-like Diplazium . Caudex 
erect ; fronds bipinnate, triangular, 3 feet long ; leaflets 
light green, serrated; stems scaly. From St. Helena. 
Diplazium juglandifolium. Walnut-leaved Diplazium . 
Caudex tufted ; fronds pinnate, bright green ; leaflets 
large, and but slightly serrated. This fern will grow if 
the stem be placed in a pot under a bell-glass ; after a 
short time roots will sprout forth, and new fronds be 
formed from the base of the old one. We have it from 
South America. 
Diplazium plantagineum . Plantain-leaved Diplazium . 
Caudex tufted ; fronds simple, fertile, dwarf. The fronds, 
planted like those of the last species, will take root, and 
it is also furnished with buds springing at the base of 
the fronds, by which also it may be propagated. Its 
home is the West Indies. 
Diplazium striatum . Striated Diplazium . Caudex 
erect ; fronds bipinnate, 4 or 5 feet in length ; leaflets
