and rather bluntly toothed, oblong, rhomboidal pinnl. ; texture subcoriaceous ; 

 veins beneath prominently raised and, like the rachises, more or less hairy ; sori 

 2 to 12 to a pinnule, small, placed at the base of the sinuses. D. Khasiyana, 

 Hk. Sp. I. p. 173. t. 47. A. and 57. A. /3 D. rhomboidea, Wall. ; similar to a 

 in texture and hairiness, but rather larger in all its parts, lower pinnl. lanceolate" 

 deltoid, 1| in. 1., cut down nearly to the rachis into oblong lobes. D. poly- 

 podioides y and d, Hk. Sp. Fil. 1 . p. 182. 



Hab. North of India, ascending in the Himalayas to 3-5,000 ft., Ceylon, Japan, 

 Malayan Peninsula and Isles, S. E. China, Sandwich and Fiji Islands. This is very 

 similar to the last in habit, but is at least bipinnatifid. 



58. D. (Micro.) platyphylla, Don. ; rhizome creeping, stout, scaly ; st. 2-3 ft. 1., 

 firm, erect; Jr. 3-4 ft. L, tripinnatifid ; lower pinnae 12-15 in. 1., 6-9 in. br,, 

 lanceolate, with distant linear lanceolate pintiL, which are cut nearly to the 

 rachis below into broad bluntish, toothed, oblong-deltoid lobes ; texture sub- 

 coriaceous, both surfaces naked ; sori 2 to 12 to a segment, placed one in each 

 tooth a short distance from the edge, about a line across. D. lonchitidea, Wall. 

 Hk. Sp. 1. p. 173. t. 46. B. Exot. F. t. 19. 



Hab. Throughout Hindostan from Ceylon to the Himalayas. 



59. D. (Micro.) urophylla, Hk. ; st. strong, erect, 2-3 ft. 1. ; fr. 2-3 ft. 1., 

 tripinnatifid ; lower pinnae 9-12 in. 1., 6-8 in. br, lanceolate with distant lan- 

 ceolate lower pinnl, which are cut down to the rachis below into ovate-deltoid, 

 acuminate, unequal-sided, broadly-toothed lobes ; texture coriaceous, both surfaces 

 naked ; sori submarginal, one to each of the lower sinuses of the lobes. HL Fil. 

 Exot. t. 19. note. 



Hab. Bootan, Griffith. 



60. D. (Micro.) Thwaitesii, Baker ; rhizome creeping, tomentose ; st. 6-12 in. L, 

 erect, naked ;fr.2-3 ft.l., lanceolate-deltoid, tripinnatifid ; Iower/>wwce9-12 in. L, 

 3-4 in. br., lanceolate ; pinnl. lanceolate-acuminate, cut down nearly or quite to 

 the rachis into blunt slightly crenated oblong lobes ; rachis and both surfaces 

 slightly hairy, the upper bright-green, shining ; texture subcoriaceous ; sori 

 small, submarginal, 2 to 12 to a segment. D. proxima, Thwaites Enum. PI. 

 ZeyL p. 238. non Blume. 



Hab. Ceylon. This comes nearest to urophylla, but the segments are shorter and 

 blunter and the sori are smaller. An authenticated specimen of Blume's plant is 

 probably D. hirta. 



61. D. (Micro.) inaequalis, Kunze ; rhizome creeping ; st. stout, 2-3 ft. 1. ; fr. 

 2-3 ft. 1., 12-18 in. br. ; ovate-lanceolate, quadripinnatifid ; lower pinnae 9-12 

 in. L, 4-8 in. br., with lanceolate pinnl. 3-5 in. L, 1-2 in. br. ; lower segm. cut 

 down nearly to the rachis with oblong toothed lower lobes ; texture herbaceous, 

 both surfaces naked ; sori 2 to 12 to a segment, small, placed in the teeth at a 

 short distance from the margin. Hk. Sp. 1. p. 180. excl. var. y. t. 57. B. 



Hab. Tropical America from Jamaica and Guadeloupe, southward to Peru and Rio 

 Janeiro, Aneiteum, and Philippine Islands. The var. nigrescens, Kunze, is a large form 

 which turns nearly black when dried. A plant from Burchell, No. 3549, marked by 

 Professor Mettenius Saccoloma Brasiliensis, Mett. (Davallia, Hook.), has the lower 

 pinnules only cut down to the rachis at the very base. 



62. D. (Micro.) campyleura, Kunze ; st. strong, erect, about 1 foot high ; fr. 

 2-3 ft. L, 9-18 in. br., deltoid, quadripinnatifid; lower pinnce lanceolate, 9-12 

 in. L, 4-6 in. br., the segm. of the pinnules cut down to the rachis into broadly- 

 toothed, oblong lobes in the lower part ; texture subcoriaceous, both surfaces 

 naked ; sori 1 to 6 in a lobe, placed in the teeth, small,j submarginal. D. 

 ineequalis, y minor, Hk. Sp. Fil. 1. p. 180. t. 58. A.
