sori copious, placed obliquely in two long rows in the pinnules near the edge ; 

 invol. broader than deep. Moore, Ind. Fil. p. 296. 



Hab. Borneo ; discovered by Mr. Thos. Lobb. A very distinct species, with tbe invo- 

 lucre resembling in shape that of Humata, but not free at the sides. 



36. D. trichomanoides, Blume ; rhizome wide-creeping, in. thick ; scales linear, 

 pale brown ; st. 3-4 in., grey, naked ; fr. deltoid, 4-pinnatifid, 6-9 in. 1. ; pinna 

 distinctly stalked, lanceolate, lowest largest, deltoid, 1^-2 in. br., all cuueate- 

 truncate on lowest side at base ; pinnl. close, lanceolate ; ult, segm. ligulate at 

 base, and forming a narrow wing above on each side of the sorus ; rachises of 

 pinnae winged to the base ; texture subcoriaceous ; surfaces naked ; sori rather 

 deeper than broad, with mostly a horn beyond on both sides. Hk. Sp. 1. p. 186. 

 D. stenomera, Kunze, Bot. Zeit. 6. p. 216. 



Hab. Malay Isles. 



37. D. Moorei, Hk. ; rhizome creeping, fibrillose ; st. erect, strong, 4-8 in. 1. ; 

 fr. 4-6 in. 1., 3-4 in. br., bi- or tripinnatifid ; main rachis slightly winged above ; 

 lowest pinnl. cut down nearly to the rachis below, the lobes oblong, bluntly 

 toothed ; texture coriaceous ; sori 4 to 6 to a lobe, placed in the teeth at a little 

 distance from the edge ; invol. half-cupshaped. Hk. 2nd Cent. Ferns, t. 53. 



Hab. New Caledonia, discovered by Mr. C. Moore. 



38. D. decurrens, Hk. ; rhixome stout, creeping, densely fibrillose ; st. 4-6 

 in. 1., stout, erect ; fr. 1-2 ft. 1., 9-15 in. br., deltoid, tripinnatifid ; main rachis 

 hardly at all winged at the apex; pinnl. of the lower pinnte lanceolate-acuminate, 

 3-4 in. 1., about 1 in. br., cut down throughout within a short distance of the 

 rachis, with broadly-toothed linear-oblong segm. ; texture subcoriaceous ; veins 

 uniform ; sori falling short of the margin ; invol. half-cupshaped. Hk. Sp. Fil. 

 l.p.lGT.t. 44. B. 



Hab. Philippine Islands. Resembles D. divaricata in the shape and position of the 

 sori, but the frond less divided. 



39. D. solida, Swartz ; rhixome stout, densely clothed with adpressed scales or 

 fibres ; st. strong, erect, 4-6 in. \.;fr. 1-2 ft. 1., 12-15 in. br., deltoid, tripinnatifid ; 

 apex with a moderately broad undivided centre ; segm. ovate-rhomboidal, deeply 

 toothed, narrower and sharper in fertile frond ; veins uniform ; texture coriaceous ; 

 sori nearly or quite marginal ; invol. semicylindrical. Hk. Sp. 1. p. 164. t. 42. 

 Fil. Exot. t. 57. /3, D. caudata, Cav. ; pinnules more divided with narrower 

 segments. Hk. Sp. 1. p. 164. D. Lindleyi, Hk. Sp. 1. p. 163. t. 48. B. 



Hab. Malayan Peninsula, Java, and Polynesian Islands. The reported station in 

 New Zealand appears to be a mistake. D. ornata, Wall., is a large handsome form, 

 with broad slightly-cut segments. 



40. D. elegans, Swartz ; rhizome stout, creeping, densely clothed with woolly 

 fibres ; st. firm, erect, 4-8 in. 1. ; fr. 1-2 ft. 1., 9-lo in. br., deltoid, tripinnatifid ; 

 main rachis slightly winged towards the apex ; pinnl. of the lower pinnae 2-3 in. 

 1., 1 in. br., deltoid-lanceolate, cut down quite to the rachis in the lower part, 

 with oblong-deltoid segm., which are slightly toothed and obliquely truncate at the 

 base on the lower side ; texture coriaceous ; venation close, prominent, irregular ; 

 sori several to a segment, marginal, but the sharp teeth projecting beyond them 

 at the edges ; invol. half-cupshaped. -Hk. Sp. 1. p. 164. /3, D. data, Swartz ; 

 fr. larger and less coriaceous ; segm. narrower, more deeply and sharply cut.
