WILSON S FILMY FERN. 



plastered this all over the inverted pot, arrange the matted 

 mass of rhizomes of the Hymenophyllums over the wet surface 

 of the mortar, taking especial care that the fronds hang ia a 

 natural position. It sometimes happens that the mass of ferns 

 will not apply itself closely to the mortar ; in which case, a 

 piece of fine galvanized ziac wire may be bound twice or three 

 times round the pot, fern, and all, taking care not to injure the 

 fronds, which may readily be so arranged as entirely to conceal 

 the wire : then fill a saucer with wet Sphagnum, and strew the 

 surface with silver sand; place the prepared inverted pot in the 

 saucer, and cover with a bell glass, the rim of which will sink 

 into the Sphagnum in the saucer : the luxuriant growth of the 

 fern is certain. My friend, Mr. Richard White, has cultivated 

 both the species of Hymenophyllum most successfully in this 

 way for eight or nine years. 



The same mode of culture will serve for both species of 

 Hymenophyllum, with this difference, that whereas the fronds 

 of tunbridgense are injured by water, except as conveyed in the 

 form of atmospheric humidity, those of unilaterale delight in 

 frequent syringings.
