DIPLAZIUM. 
~ 
DIPLAZIUM DECUSSATUM. (Wall.) Caudex erect, stipes 12-16 inches long scaly towards the base, fronds 8-10 inches 
long, 6-8 inches broad at the base, deltoid ovate, pinnate ; pinnæ about 8 on each side alternate (below the pinnatifid apex) lower ones 
petiolate, middle ones sessile, upper decurrent, 3-4 inches long š to nearly 1 inch broad, pinnatifid 2-3rds down to the costa, segments 
with a very rounded apex toothed at the margin, veins straight or more or less flexuose, veinlets 5-6 on each side of the segment, 
alternate or opposite, generally simple, sometimes forked, reaching the margin or terminating just within it; rachis costa and veins - 
sparingly furnished with setaceous hairs, sori lower ones double, upper single. Wall, Cat. No. 2208. 
The specimen figured is from Ceylon (C. P. 3951) and I have lately found it on the Tinnevelly hills; itis nearly allied to 
D. iasiopteris but has a different caudex. Mr. Baker refers it to Diplaz. Schkuhrii, Hook. Pl. 230 of this work, and places both under - 
D. Japonicum Thunb, which has a creeping caudex. The species that I have سی‎ as D. Schkuhrii has an erect wa. but is bipin- A 
nate in its larger fronds which this species appears never to be. 
Hab, Ceylon, Tinnevelly Hills, Himalayas.
