134 Filmy Ferns in Cases and under Bell-(/lasses. 



A gentle circulation of air must always be provided for 

 them, especially when the temperature is low, owing 

 to the great amount of moisture in the atmosphere

 the fronds being from one to six inches long and of a

H. flexuosum ; this species is as like a Selaginella as

H. pullchurinum, a New Zealand species of a large
