STOVE FEENS. 



It makes long creeping rhizomes, which grow very fast : con- 

 sequently it looks well grown in a suspended wire basket. It 

 is also a native of the East. 



HYHENODIUM. See Dyctyoglossum. 



HYMENOPYLLUM. 



Of this beautiful and interesting genus there are several 

 species which require a stove temperature. The mode of 

 treatment under which they succeed best is the same as that 

 of the Trichomanes, to which genus we refer our readers for 

 further information on this point. Messrs. Backhouse and 

 Son, of York, have devoted much attention to this genus and 

 the allied one, Trichomanes. They have introduced a great 

 number of species ; and the collection has been further in- 

 creased by Mr. E. Sim, who has imported some very lovely 

 Ne \v-Zealand forms. 



HYMENOPHYLLUM ABEUPTUM (Abrupt or blunt). A pretty 

 little West-Indian Fern, with broad, once-divided, smooth, 

 semi-transparent fronds, which are 2 inches long, and rather 

 blunt at the apex, whence its name is derived. 



H. CILIATUM (With hairs, like eye-lashes, round the mar- 

 gins). Introduced several years ago from Jamaica. It forms 

 dense clusters of its delicate little fronds. When once esta- 

 blished it rapidly increases. The other stove kinds we mention 

 by name, but they are, and will be for some time, very rare. 

 H. asplenioides (asplenium-like), H. cruentum (crimson), H. 

 hirsutum (hairy), jET. nudum (naked), H. Plumieri (Plumier's), 

 and H. sericeum (silky). 



HYPODEKRIS. 



Derived from the Greek Jiypo, under, and derris, skin; 

 from the indusium being attached partly under the sori. 

 There is only one representative of this genus in cultivation.
