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 midrib 
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 pleocnemia trimeni. {Bedd.) 
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 (/>., compital), in- 
dusium reniform. Sagenia gigantea, Bedd. F. S. I. t. 80 {not the 
deso'ipiion.') Pleocnemia gigantea (Baker), Hook. Syn. Fit. 2nd 
Edit. p. 503, not Blume. 
The Kew packet of giganteum from which Sir W. Hooker took 
his description {Sp. Fit. iv. /. 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.
