D. (Eudavallia) trichomanoides — Eu-dav-al'-li-a ; trich-om'-an-6-i'-des 

 ( Triclaomanes -like) , Blume. 

 This very pretty, stove species, tlie name of which is also wrongly applied 

 to D. ferulacea^ is provided with wide-creeping rhizomes |in. thick, covered 

 with long, narrow, pale brown 

 scales. It is a native of the Malay 

 Islands, and also of Ceylon, where 

 it was found by Thwaites, on 

 Adam's Peak, at about 3000ft. 

 elevation. Its fronds, 6in. to 9in. 

 long, of an elongated -triangular 

 shape and four times pinnatifid 

 (divided half-way to the midrib), 

 are borne on grey, naked stalks 

 Sin. to Gin. long. The leaflets are 

 distinctly stalked, spear-shaped, the 

 lowest and largest being IJin. to 

 2in. broad, and divided into close, 

 spear-shaped pinnules (leafits), 

 which in their turn are cut into 

 strap-shaped segments of a some- 

 what leathery texture. The sori 

 (spore masses), which are rather 

 deeper than broad, mostly show 

 a horn projecting beyond on 

 both sides. Fig. 37 is reduced 

 from Col. Beddome's " Ferns of 

 British India," by the kind per- 

 mission of the author. — Hooker,
