HEMIDICTYUM HUMATA. 



it off and plant it in a small pot placed under a bell-glass 

 till fairly established. 



HEMIDICTYUM. 



The genus was formed by Presl, the name being derived 

 from hemi, half, and diJctyon, a net; from the veins being 

 netted only halfway across the pinnules. There is only one 

 species in cultivation, and it was formerly called Asplenium (or 

 Diplazium) marginatum. 



HEMIDICTYUM MARGINATUM (Margined). A native of tro- 

 pical America. The fronds of this noble Fern rise to the 

 height of 5 or 6 feet. They are pinnate, the pairs of pinnae 

 being each a foot long and 2 or 3 inches wide. The fronds, 

 as well as the stalks supporting them, are quite smooth, and 

 of a pale green colour. The fronds are very thin, and rapidly 

 turn brown at the edges if the sun be allowed to shine upon 

 them.

HTJMATA. 



The plants arranged under this name of Cavanilles' formerly 

 formed a part of the large genus Davallia. The cups con- 

 taining the spore-cases stand out along the margin of the 

 fronds. There are only two species in cultivation, and one 

 of these, H. pedata, is extremely rare. It is a native of the 

 East Indies, and produced little divided fronds, triangular in 

 outline, and of a dark green colour. They are not more than 

 3 inches in length. The soil should be piled up into a cone 

 above the rim of the pot, and the creeping rhizomes pegged 

 to it. 



HUMATA HETEEOPHYLLA (Variously-formed leaved). The 

 sterile fronds of this Fern are lance-shaped and undivided, 

 but the fruit-bearing ones are deeply cut along the margin.
