^2 Ferns of British India and Ceylon. 
6. Leucostegia Hookeri. {Moore, under Acrophorus) Rhizome 
stout ; scales dense, lanceolate, golden ; stipe up to 6 inches long 
slender often scaly at the base ; fronds deltoid up to lo inches long, 
3-4 pinnatifid ; lower pinnae opposite or alternate, lanceolate or 
deltoid, 1-2 inches broad ; pinnules deltoid, ultimate segments 
ligulate, acute, i -veined, \-\ line broad texture; membranaceous; sori 
at the base of the ultimate lobes; involucre persistent, membranaceous, 
broader than long. Davallia Clarkii, Baker, Syn. Fil. p. 91. 
Himalayas, Lachen, and Sirmur, 8,000-12,000 feet elevation. 
Sundukphoo, near Darjeeling, 11,000 feet. 
Very like Polypodium dareaeforme. Hook., but with acute seg- 
ments, and differing somewhat in the scales of the rhizome. Indian 
botanists, not having seen this plant, have quoted Hookeri of Moore 
(Clarkii of Baker) as a synonym of dareaeforme, and united the 
two under the name of Leucostegia dareaeformis. Mr. Levinge 
has lately gathered this species at Sundukphoo, but the Kew 
specimens from Lachen and Sirmur were gathered by Thomison in 
1849. I have examined a great many specimens of dareaeforme in 
the Kew Herbarium, and can find no trace of an indusium, so I retain 
it in Polypodium ; but it is very likely that there is a fugacious 
indusium, and that it is a Leucostegia nearly allied to this species. 
7. Leucostegia pulchra. {Don. under Davallia.) Rhizome 
wide-creeping, clothed with broad-obtuse, often peltately attached 
scales; stipe 4-6 inches long, naked; fronds 9-15 inches long, 4-8 
inches broad, lanceolate-deltoid, 3-4 pinnatifid, lowest pinnule 1-2 
inches long, i inch broad, cut dpwn to a narrowly-winged rachis into 
deeply pinnatifid segments, ultimate lobes narrow lanceolate, not 
distant, not very acute ; texture thin, rather flaccid ; sori copious, 
usually as broad as the segment at the base of the teeth of which it 
is placed ; involucre prominent. Den. Prod. Fl. Nep. 11. Bedd. 
F. S. I. t. 10 (under Acrophorus). 
Madras Presidency, Western mountains, very common on rocks 
and trees ; Ceylon, central provinces, 3,000-5,000 feet; Himalayas, 
Nepal, and Bhotan, 2,000-9,000 feet ; Khasya; Moulmein.
