 the East Indies, Loth on the Continent and Islands, and in Tropical 

 New Holland. Remarkable for the elegant divisions of its fronds, and for 

 the dark-coloured lines upon the segments, giving them a striated appear- 

 ance, but wbicli can hardly be called true veins, for they are often not visi- 

 ble when the frond is held up between the eye and the light, although the 

 real veins then become more apparent. I regret that this striated appear- 

 ance is omitted (nor is it easy to represent it in a figure) both in the plate 

 of Schkuhr, and in the outline sketches here given: but something of the 

 kind is shown upon our D. elata, Tab. LV. A. 



35. D. ?iitidala, Kze. ; "frond triangidar subcoriaceous 

 nearly glabrous paler beneath subtripartite tripinnate, pinnae 

 alternate ]ietiolate patent ovate acuminate slightly curved 

 lowest ones more remote nearly ojiposite, secondary pinnides 

 from a cuneate base unequally ovate obtuse pinnatilid or in- 

 cised, segments cuneato-oblong retuse or subemarginate at 

 the apex subincised bearing sori, involucres obovate trun- 

 cated, rachis and moderately long stipes llexuose glabrous, 

 caudex creeping chally." Kze. (Tab. XLIV. A.) — Kze. Fil.

Hab. South Africa, Drege. — Kunze'srepresentixtion of this plant is excel- 

 lent, and I would not have pul)lished my present figure (admirably as it 

 represents a portion of the plant), but that it was prepared before I was 

 ac(iuaintcd with Kunze's plate. The aflinity of the species is surely with 

 D. e.legms, I think rather than with D. data, as the accurate Kunze inti- 

 mates. It dilfers however I'rom our last species in the absence of stria*.
