Ferns of British India and Ceylon. 



stipes i foot or more long; fronds 12-18 inches long, 8-12 inches 

 broad, subdeltoid with a large deeply pinnatifid apex, with lanceolate 

 lobes ; below this one or two pinnse on each side, the lowest stalked, 

 distant, forked at the base, or pinnatifid, the point lanceolate ; texture 

 herbaceous, surfaces somewhat hairy beneath and on the main veins 

 above, main veins distinct to the edge, the others copiously anasto- 

 mosing, with free veinlets included in the areoles ; sori rather large, 

 but scattered, confined to the connected veinlets ; indusium reniform.

Ceylon and the Malay Peninsula. 

 My Ceylon specimens are much smaller 

 than those from Birma, but I believe 

 they are the same species; in habit it is 

 quite like variolosum, but the sori are 

 always on the netted veinlets, instead 

 of at the apex of free veinlets. 



6. Aspidium variolosum. (Wall.) 

 Rhizome suberect, stipes tufted, scaly 

 near the base only, 12-18 inches long 

 in the fertile, less in the sterile fronds, 

 more or less dimorphous, deltoid in 

 outline, herbaceous in texture, and some- 

 what puberulous, especially in the sterile 

 ones ; pinnae about three pair below the 

 pinnatifid apex, the lowest pair again 

 pinnated with the pinnules often pin- 

 natifid, the next pair often pinnatifid or 

 pinnated in a less degree, the pinnae of 

 the fertile fronds generally narrower and often more divided, main 

 veins not very distinct but more so in the fertile than in the sterile; 

 areoles copious, with many free included veinlets ; sori rather large, 

 almost always at the apex of the free veinlets, very rarely on the- netted 

 veins; indusium peltate and reniform on the same frond. Wall.
