Ferns of British India and Ckylon. 



more than half-way to the rachis, about 8-9 inches long by 2 broad, 



and a much larger basal pair which are deltoid, again pinnated with 



the lower basal pinnules deeply pinnatifid, ultimate lobes bluntish, 



slightly crenated or nearly 



entire ; texture rather thin ■ 



surfaces glabrous on both 



sides ; costas and veins rusty 



above, less so or nearly 



glabrous beneath ; lower veins §| 



forming elongated costal arches 



near the rachis of the pinnae, 



with generally a second series 



of areoles formed by the veins 



again anastomosing angularly, 



veins of the segments only 



anastomosing near the midiib 



and forming one series of 



arches, the rest free, no free 



veinlets in the areoles ; sori in 



a single row on each side of 



the midrib, those towards the 



margin and apex of the 



segments apical on the free veinlets, those lower down and nearer the 



costa of the pinnules generally on connected veins {i.e., compital), in- 



dusium reniform. Sagenia gigantea, Bedd. F. S. I. t. 80 (not the 



description.*) Pleocnemia gigantea (Baker), Hook. Syn. Fil. 2nd 



Edit. p. 503, not Blnme. 



The Kew packet of giganteum from which Sir W. Hooker took 

 his description (Sp. Fil. iv. p. 50,) contains several different species; 

 the Java specimen being a single pinna of Aspidium giganteum, a 

 species distinct from this ; the Birma and Assam specimens being 

 multicaudatum (Wallich) ; and the Ceylon specimens being this 

 plant, Pleocnemia membranacea, and P. Thwaitesii. This not being 

 Blume's giganteum I have had to rename it. 



Ceylon, central provinces, (C.F. 1357); South India, Anamallays, 

 Palghat side, in the forests near the Nelliampady coffee estates.
