Ferns of British India and Ceylon. 181 



the rhizome creeping, though it is generally erect ; in lasiopteris and 

 Thwaitesii it is wide creeping. I have seen nothing like Mr. Clarke's 

 variety chattagramica, with bipinhate fronds, the secondary pinna? 

 petioled and the rachis not winged, and can hardly fancy it belongs 

 here, the specimen could not be found at Kew, but from the figure 

 in Clarke's Review, it appears to be one of the numerous forms of 

 latifolium and perhaps the same as the one he calls succulentum. 

 Mr. Clarke is quite wrong in referring Schkuhrii Thwaites here, he 

 did so on a specimen of my decurrens, wrongly named Schkuhrii, 

 but decurrens (which is Thwaites's polypodioides var. /3 c. p. 3332, 

 and Moore's dilatatum, var. /3 minor), can have no place here. 



Madras Presidency, on the Western ghats, the supposed 

 lasiopteris at Ootacamund, 7,000 feet, and Poombary on the Pulneys, 

 7,000 feet ; decussatum on the Tinnevelly Hills and Jeypore Hills, 

 West of Vizagapatam, 3,000-4,000 feet. Ceylon, central provinces; 

 N. W. Himalayas; Nepal; Nynee Tal; Kangra; Kumaon; Khasya, 

 3,000 feet; Malay Peninsula.

13. Diplazium Schkuhrii. (Thiaaites.) Caudex erect ; scales 

 dense, small, lanceolate, dark-brown; stipes 9-18 inches long, 

 naked ; fronds deltoid-lanceolate, up to 2 feet long, bipinnate below, 

 bipinnatifid above ; pinnae alternate, lower ones distant, 6-8 inches 

 long, by 1^-2 inches broad; rachis winged; pinnules distant, sessile 

 ligulate-oblong, all very regular in shape, f~| inch long, -f-J inch 

 broad, pinnatifid about ^ down into rounded lobes ; texture rather 

 firm ; surfaces glabrous, bright-green ; veinlets simple or pinnated in 

 the lobes ; sori linear, generally reaching from the midrib to the 

 sinus between the lobes, double or single. In younger plants or 

 smaller specimens, the fronds are often pinnate only, i.e., the 

 primary pinncc only pinnatifid half to two-thirds to the rachis.
