46. D. Canariensis, Smith ; rhizome stout, creeping, densely clothed with pale- 

 brown linear scales ; st. strong, erect, 4-6 in. 1. ; fr. 12-18 in. 1., 9-12 in. br., 

 deltoid, quadripinnatifid ; pinnl. of the lower pinnse lanceolate-deltoid, 2-3 in. h, 

 more than 1 in. br., with ovate - rhomboidal deeply inciso-pinnatifid segm. ^ 

 texture coriaceous ; sori occupying a whole ultimate division or with a horn 

 beyond them ; invol. half-cupshaped. Hk. Sp. I. p. 169. t. 56. A. 



Hab. Spain, Portugal, N. Africa, the Canaries, and Madeira. 



47. D. bullata, Wallich ; rhizome creeping, stout, densely clothed with light- 

 brown or whitish fibrillose scales ; st. strong, erect, 3-4 in. 1. ; fr. 8-12 in. 1., 

 4-8 in. br., deltoid, quadripinnatifid ; pinnl. of the lower pinnse lanceolate, 2-3 

 in. 1., 1 in. br., with deeply inciso-pinnatifid. oblong-rhomboidal segm.; texture 

 coriaceous ; sori deeply half-cupshaped, occupying the greater part of the tooth in 

 which they are placed, marginal, with usually a horn on the outside. Hk. Sp. 

 Fil. 1. p. 169.*. 50. B. 



Hab. Hindostan, ascending in the north to 3-4,000 ft., Japan, Java, and Malayan 

 Peninsula. Very near D, Canariensis and pyxidata, but smaller, and somewhat thinner 

 in texture, and the scales of the rhizome different. 



48. D. nitidula, Kunze ; rhizome stout, creeping, fibrillose ; st. 6-8 in. 1., firm, 

 but rather slender; fr. 12-24 in. 1., 9-15 in. br., deltoid, quadripinnatifid ; pinnl. 

 of the lower pinnse deltoid, cut down to the rachis into rather distant deltoid 

 segm., the lobes of which are again deeply pinnatifid ; texture between herbaceous 

 and coriaceous ; sori half-cupshaped, two-horned, occupying the whole of the 

 end of the ultimate teeth. Hk. Sp. Fil. I. p. 165. t. 44. A. 



Hab. Natal, Dr. Pappe ; and fine specimens have recently been gathered by Dr. Wel- 

 witsch in Angola at 1-2,000 ft. Frond rather flaccid, rachises slender and flexuose. 



49. D. Fijiensis, Hk. ; rhizome creeping, stout, densely fibrillose ; st. 6-9 in. 1., 

 erect, strong ; fr. 12-18 in. 1., 6-12 in. br., deltoid, quadripinnatifid ; pinnl. of the 

 lower pinnae deltoid-lanceolate, the lobes of the segment cut down nearly to the 

 rachis into narrow linear divisions, - in. 1. ; texture coriaceous ; sot~i half- 

 cylindrical, terminal on the dilated apices of the segments, sometimes with a 

 slight wing, but no horn. Hk. Sp. I. p. 166. t. 55. D. 



Hab. Fiji Islands, plentiful. The most finely-divided species of the series. 



Microlepia. Invol. membranaceous, shallowly half-cupshaped, attached at 

 the sides as well as the base. Sp. 50-65. Fronds very various in size, texture, and 

 cutting. This sub-genus has its head-quarters in S. E. Asia and Polynesia. Four 

 species are American and one African. Differing also from Humata, Eudavallia, 

 and Leucostegia, in having the stems, except in D. ciliata, continuous with the 

 caudex, and consequently falling under a different primary division (Desmobrya} of 

 J. Smith's classification. 



50. D. (Micro.) Hookeriana, Wallich ; rhizome creeping, both it and the lower 

 part of stem pubescent-fibrillose ; st. stout, erect, 4-6 in. 1. ; fr. 12-18 in. 1., 6-8 

 in. br., simply pinnate ; largest pinnae 4 in. 1., f in. br., linear-adimiriato, 

 truncate and auricled at the base above, slightly undulated below, and tootheu 

 towards the point ; texture subcoriaceous ; rachis and veins beneath villose ; sori 

 in continuous rows along the edges ; invol. small, about as broad as deep. Hk. 

 Sp. I. p. 172. t. 47. B. 



Hab. Sylhet, Kamoun, and Assam, Hongkong. 



51. D. (Micro.) Saccoloma, Spreng. ; rhizome wide-creeping, often climbing ; 

 fr. 4-6 ft. 1., simply pinnate ; lower pinnae 1 ft. 1., rather over 1 in. br., linear- 

 acuminate, sharply but not deeply toothed towards the point, undulated
