io Ferns of British India and Ceylon. 



2. Amphicosmia decipiens. {J. Scott, under Hemitelea.) A 

 lofty tree fern, very prickly on the main and secondary rachises, 

 tertiary rachis (that of the pinnules) bullate-scaly, not pubescent ; 

 pinnules glabrous, or nearly so, segments sometimes much narrowed 

 where fertile ; veinlets forked, or often three-branched and even four- 

 branched in the sterile portions ; sori in two rows close along the 

 main veins or costa of the segment ; involucre a hemispheric cup. 

 J. Scott, in Lin. Trans, xxx. 33, t. 14. Bedd. F. B. I. t. 311. Shows 

 the veins and bullate scales correctly, but not the involucre. 



Sikkim and Bhotan, 1,000-4,000 feet. Khasya below Nung- 

 klow. Differs from the next in being much more prickly and in 

 the segments being generally longer and narrower. I do not feel 

 certain it is distinct from Cyathea spinulosa, as I have not seen the 

 involucre in very young state. 



3. Amphicosmia Brunoniana. ( Wall, under Alsophila.) A 

 large tree fern; main rachis somewhat prickly, secondary rachis 

 slightly muricated or smooth ; rachis of the pinnules, crisped-pubes- 

 cent ; segments minutely hairy on the veinlets (under the lens), not 

 contracted in fruit ; veinlets forked, or three-branched veinlets very 

 rare ; sori and involucre as in the last. Clarke, p. 430. Alsophila 

 Brunoniana, Wall. Alsophila latebrosa, var. hemitelioides, J. Scott, 

 1. c. 34. 



Sikkim and Bhotan, 4,000-7,500 feet; East Nepal; Khasya 

 3,000-5,000 feet, very common. 



The specimen for which Mr. Clarke gives the locality "Deccan " 

 is a specimen of Cyathea spinulosa, collected at Mendeb in Canara 

 by Dr. Richie. 



Mr. Clarke's variety /J Scottii, " segments of the fertile pinnules 

 unusually large, deeply crenated, with many three-branched veinlets," 

 is founded on a single pinna in the Kew Herbarium, collected by 

 Scott in Sikkim and labelled by him latebrosa, var. (3; it is perhaps 

 a new species. 



4. Amphicosmia alterans. {Hook, under Alsophila}) Rachis 

 glabrous, smooth, turning brown ; fronds subcoriaceous, glabrous, sub-
