MR. C. B. CLARKE ON THE FERNS OF NORTHERN INDIA. 451 
forms, var. 1 may be 2-4 in. high, growing in river-sand, the pinne small, very 
coriaceous and hard, all slanting towards the vertex of the frond; var. 2 in rich soil 
may be 18 in. high, with large herbaceous pinnz spreading horizontally. All inter- 
mediate forms may be found.—Lindsaya attenuata, Wall Cat. 2192, is quite remote 
from L. attenuata, Wall. Cat. 151, and comes from Herb. Finlayson, probably collected 
in Siam or Cochin-China. 
2. L. REPENS, Bedd. Ferns South. Ind. tt. 209, 214. Frond simply pinnate; scales of the 
rhizome lanceolate ` pinnee unequal-sided, lower edge nearly straight near the main 
nerve; veins free, or uniting only at the base of the sori—JZ. pectinata, Blume,

Rhizome stout, usually climbing. Fronds 12-18 in., very much like the large form 
of Z. cultrata, but the rhizome and scales differing —This is a very rare fern in North 
India, having apparently been collected but on three occasions. The locality, Nilgherries, 
given for it by Mr. Baker, is objected to by Col. Beddome; and I can find no Nilgherry 
example at Kew. Lindsaya pectinata and Davallia repens of Hk.& Baker, Syn. Fil., are 
so identical that I imagine the two are only retained in the text because stereotyped. 
Both species are attributed to North India on the faith of Griffith’s three sheets, two of 
which (collected from the same plant?) are arranged one in the Davallia repens bundle, 
the other in the Lindsaya pectinata bundle. Baker doubts whether L. scandens, Hk., 
is distinct ; but Mr. Baker has marked one sheet L. pectinata, which I consider typical 
L. scandens, and this, of course, spoils all. There remains the question whether the 
species should be called Lindsaya or Davallia. I should resolve this by transferring the 
whole section Odontoloma to Lindsaya. e
