Ferns of British India and Ceylon. 
2. Amphicosmta decipiens. (y. 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 buUate 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 
Tare ; sori and involucre as in the last. Clarke, p. 430. Alsophila 
Brunoniana, Wall. Alsophila latebrosa, var. hemitelioides, y. ^S^r^?//, 
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 spmulosa, collected at Mendeb in Canara 
by Dr. Richie. 
Mr. Clarke's variety 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-
