D. (Odontoloma) Blumeana— Od-on-tol-o'-ma ; Blu-me-a'-na (Blume's), 

 Hooker. 



This very distinct and beautiful, stove species, native of tlie Philippine 

 Islands, has fronds Sin. to 12in. long, Gin. to Sin. broad, bipinnate (twice 

 divided to the midrib), borne on strong, erect stalks 4in. to 6in. long, and 

 produced from a creeping rhizome (prostrate stem). The leaflets, 4iii. to 6in. 

 long and Jin. broad, are of a somev^hat rigid nature and divided into pinnules 

 (leafits) that are cut down on the upper side into fihform (thread-hke) 

 segments, either simple or forked, and on the enlarged extremities of which 

 the small and roundish sori (spore masses) are situated. — Hooker^ Species 

 Filicum, i., p. 177, t. 54. 



D. brachycarpa — brach-yc-ar'-pa (short-fruited). A variety of D. gibberosa. 



D. (Odontoloma) brachypoda— Od-on-tol-o'-ma ; brach-yp'-od-a (short- 

 footed). Baker. 



A very small, greenhouse species, with fronds Im. to l|in. long, strap- 

 shaped, nearly stalkless, simply pmnate (only once di^uded to the midrib), and 

 of a bright green colour. The sori (spore masses), disposed on the margins 

 of the leaflets, are covered with involucres that are rather broader than deep. 

 This species is found in a wild state on the banks of the Gilbert, North 

 Australia. — Hooker, Synopsis Filicum, p. 468. 



D. (Eudavallia) bullata — Eu-dav-al'-li-a ; bul-la'-ta (blistered), Wallich. 



This handsome, deciduous, greenhouse species (see Coloured Plate), of 

 medium growth, native of Japan, Java, and Hindostan, where it ascends to 

 altitudes of 3000ft. to 4000ft., is popularly known as the " Squirrel's -foot 

 Fern," from the general appearance of its creeping rhizomes (prostrate stems), 

 w-hich are invariably clothed with minute scales of a reddish-brown colour. 

 The fronds, which are abundantly produced on these rhizomes, are Sin. to 12in. 

 long, 4in. to Sin. broad, somewhat triangxilar, quadripinnatifid (four times 

 divided half-way to the midrib), of a rich, dark shining gTcen colour, of a 

 leathery texture, and are borne on rather slender, yet firm, stalks Sin. to 4in. 

 long. The dee|)ly half-cup-shaped sori (spore masses) occupy the greater 

 part of the tooth in which they are placed on the margin of the segments, 

 and are usually provided with a horny projection on the outside. — Hooker,
