D. (Eudavallia) epiphylla— Eu-dav-aF-li-a ; ep-iph-yr-la (upon a leaf), 

 Blume. 



A strong-growing, stove species, native of Java and the Malayan 

 Peninsula, having foliage still more coriaceous (leathery) than in I), eleqans^ 

 more finely-divided segments, very small spore masses, and sharp teeth 

 protruded considerably beyond them. — Hooker, Synopsis Filicum, p. 96. 



D. (Leucostegia) falcinella — Leu-cos-teg'-i-a ; fal-cin-eF-la (finely 

 hooked), Presl. 



A stove species, native of the Philippine Islands, producing from a 

 creeping rhizome (prostrate stem) thickly clothed with purplish-black, rigid 

 hairs its triangular fronds ; these are 4in. to 6in. long, Sin. to 4in. broad, 

 and three or four times divided half-way to the midrib, which is slightly 

 winged. The leaflets are unequal-sided, and are divided into oblong pinnules 

 (leafits), which are again deeply toothed ; the ultimate divisions of the fertile 

 fronds are hooked and sharp-pointed, whereas those of the barren ones are 

 broader and not so sharp. The sori (spore masses), two to six to a lobe, are 

 placed at the base of the teeth. — Hooker, Species Filicum, i., p. 159. 



D. (Stenoloma) ferruginea — Sten-ol-o'-ma ; fer-ru-gin'-e-a (rusty), 

 Desvaux. 



This is a singular, stove species, native of Madagascar, which produces from 

 an underground, slowly -creeping rhizome (prostrate stem) its long fronds of 

 creeping or half- climbing habit, like those of D. aculeata, but the stalks of 

 which are not prickly. These fi^onds are four times pinnatifid (cut nearly to the 

 midrib), and the leafits of the lower leaflets, of a thin, papery texture, are 2in. 

 to Sin. long ; their segments are wedge-shaped at the base and deeply toothed. 

 The small and numerous sori (spore masses) are marginal, shallow, usually 

 cup -shaped, sometimes as broad as the lobe in which they are placed, some- 

 times two running together. — Hooker, Synopsis Filicum, p. 102. Nicholson, 

 Dictionary of Gardening, iv., p. 530. 



D. (Leucostegia) ferulacea — Leu-cos-teg'-i-a ; fer-ul-a'-ce-a (having 

 leaves like Giant Fennel), Moore. 

 This pretty, stove species, also erroneously known as D. trichomanoides 

 (which is totally diflerent), is a native of the Fiji Islands. Its very finely-
