Ottokaria 
Zeiller, Pal. Indica, n. s., vol. Il, 1902, no. 1, note to p. 34. 
Ottokaria ovalis n. sp. 
Pl. vii, fig. 7, 7A 
Leaflet pedicellate, oval, the blade being 2.5 centimeters in length 
and 2 centimeters in width, very thick, and bordered by short, close 
obtusely rounded, radiate éeeth, about 1-1.5 milimeter in length nearly 
as broad ; nervation radiating from the apex of the densely striate 
petiole in broad, somewhat sinuate, outward curved dichotomising 
JSascicles, the ultinate fibrous divisions of which enter the rounded 
feeth. 
The specimen described above is evidently generically identical 
with the fossil published by Zeiller from the Karharbari beds. 
It differs from the type species, Ottokaria bengalensts (1) by the 
oval form of the blade, and the very much shorter, smaller, and more 
rounded teeth. The nervation of the Indian type is described hy Zeiller 
as formed by slender filaments reunited in fascicles which radiate 
from the summit of the petiole, at the same time dichotomising. 
As indicated in figure 7, Plate vii, the Brazilian specimen has a 
nervation similar to that of the Asiatic type. But on a close examina- 
tion it is seen that the dichotomous and somewhat flexuose vascular 
bands approach to contiguity in placcs and even seem to experience an 
interchange of fibres amounting, as it seems to me, to obscure anas- 
tomosis. The examination, with the lens, of the photographic en- 
largement of the leaf shown by professor Zeiller in figure 9 A of his 
memoir seems to show an aspect suggestive of indistinct elongated 
meshes comparable to those in the type from South America. Fur- 
thermore our specimens are marked by shallow depressions exactly 
similar to those obscurely indicated in his photographic enlargement. 
These depressions correspond in the Brazilian specimen to the posi- 
tions of the small oval sporangioid bodies, Pl. vii, figure 7 a, seen 
on the counterpart of the fossil. Another point of agreement lies in 
(!) Feistmantelia bengalensis as described ond p. 34, vol. II, u. s., of the Palaeon- 
tologia Indica, but changed to Oltokaria in a supplementary corrective note, the former 
ooneric name having been already employed by protessor Lester F. Ward for another 
venus of fossil plants from the North American Mesozoic.
