 ^nenophylldcew. A large genus of filmy ferns allied to 

 Trichomanes, but having a more or less deeply 2-hpped 

 or 2-valved involucre. Some 80 species are found in the 

 tropics of both hemispheres. One species appears in 

 wells in England. 



Hi/wenophyllum demissnm is a difficult plant to grow. 

 It nee<ls a Wardian case in a coolhouse, and occasional 

 sprinkling overhead. The members of this genus are 

 propagated slowly by division.
