ral fonn or oiilliiie rcscinMing D. punctilolia, but dilTcrent in the divisions 

 of tlic pinnrr. The h)\ver pinna; arc very short, nmnerous on the lower part 

 of the nichis or stipes, and there remote. The name is, no doubt, given 

 from the consjticuons sori on the somewhat contracted tectli, resembling 

 glolndar appendages. Stipes and racliis brown, glossy, stout. 



43. D. del foiden, Hook.; frond deltoicl-ovcate quadripinnale, 

 pinnules oldong-cuncate iiinnatifid, the segments linear ob- 

 tu.sc few on a winged racliis, sori terminal npon the shorter 

 segments, rachiscs (the main one zigzag) costifi and frond (in 

 a slight degree) hairy. (Tab. XXVIII. A.) 



llab. Ceylon, Mrs. Gcnl. irrt/A-rr.— Stipes fi— 8 inches long, a little rough, 

 glossy brown. Frond I foot long, much divided, the segments narrow. Ul- 

 timate rachiscs winged, and the racliis which bears them slightly winged or 

 comj)ressed.— 1 have received this very distinct species from no other source 

 but that just mentioned. 



44. D. scabra, Wall. ; fronds ovate acuminate bipinnate, 

 pinna? ovato-lanccolate acuminate pinnatifid deeply and near- 

 ly to therachis, segments with 3 — 4 teeth or again pinnatifid, 

 sori terminal upon the teeth cu]vshaped, upper portion (form- 

 ed of the lobide of the frond) firm and subcoriaceous, lower 

 more membranaceous, sti]jes very long, and as well as the 

 rachis scabrous and more or less clothed with long tawny 

 spreading hairs especially at the base of the stipes, costa 

 slightly hairy. (Tab. XXVIII. B.) Wall. Cat. n. 2173. 



Hall. Nepaul, Wallich. Assam, Mrs. Mack. Northern India, Mr. Edge- 

 u'orth. — A very handsimie and distinct species, with a long, creeping, hairy 

 caudex. Stipes I — U foot •" length, chestnut-coloured. Fronds scarcely a 

 foot long, pale stramineous green, occasionally slightly hairy. 



45. D. c/tneaia, Hook. ; glabrous, fronds ample spreading 

 4-pinnatc, pinnides broadly rhomboid-ovate from a winged 

 rachis very obtuse the cuneate base tapering into a footstalk 

 lobato-dentate subpinnatifid, the lower lobe above the largest, 

 sori in the axil of the teeth or lobes solitary. (Tab. XXVIII. 

 C.) Sitolobium cuneatum. J. Sm. En. Fil. PJtilipp. j)' 418, 

 [uavic only). 



Hab. Luzon, Manilla, Cuming, n. 31. — A handsome species, and well 

 marked by the copious, rhomboid-ovate, very obtuse pinnules, slightly 

 lobed and auriculate, tapering into a short petiole, and arising from a 

 narrow winged rachis. 



46. D. Si/nihii, Hook.; fronds tripinnate ample spreading, 

 pinna) large lanceolate acuminate firm caudate deeply piur 

 natifid to the costa, segments or pinnules ovato-lanceolate 

 cuneate at the base toothed or dentato-pinnatifid narrower in 

 the fertile fronds, sori in the axils of the teeth or ultimate 

 segments solitary, primary and secondary rachis very straight 

 stout rigid and as well as the costa and veins pubescenti-
