[VOL. IX. 
The flora of the Jabalpur group is more numerous than that of the Kach beds, but it 
exhibits the same character and some of the same peculiarities. I will proceed now to 
describe the plant remains. 
A.—E Q XJISETA CE2E. 
As in Kach, we find also in the Jabalpur group a complete want of any plants of this 
order; but I think the jurassic period, above the lias, did not, on the whole, abound in 
equisetaceous plants, the scarcity of them also marking the whole cretaceous epoch until 
they become again more frequent in the tertiary rocks. 
Even in our liassic Kajmahal group the equisetaceous plants were very rare and 
represented only by Equisetum Hajmahalense, Schimp., from the Kajmahal Hills; while in 
the Panchet group and Damuda series the frequence of equisetaceous plants is represented 
by the very triassic Schizoneura, Schimp. 
B. — FILICES. 
In the Jabalpur group ferns are much more frequent than in Kach, and altogether 
better preserved, the rock being less sandy and micaceous. With the new species I will give 
a short diagnosis and will indicate shortly the relations, not omitting relations with older 
fossils than jurassic. 
I. —Sphenopteeides. 
There is only one species closely allied to a form in Europe only known in the oolite. 
1. —Sphenopteris arguta, Lindl. and Hutt. 
There is little doubt that our specimen must be referred to this species, its greater size 
only made me hesitate to identify it completely, but the whole habit and form of the leaf, &c., 
agree. Erom the Satpura basin. 
II. —Neubopteeides. 
None of the real Neuropteris have been found, but there is another plant which is 
generally brought in connection with Neuropterides ; it is a Cyclopteris , Bgt., and belongs to 
that division, distinguished by the name Baiera, Braun., which does not indicate more than a 
mesozoic Cyclopteris, Bgt. 
1. —Cyclopteris lobata, Estm. [Compar. Cyclopt. (Bajera) digitata, L. and H.] 
Folia semicircularia, basi emarginata, cordata (?) margine lobate, loins (laciniis) ut 
videtur deuticulatis ; nervis e basifoliortim radiatim usque ad marginem eggredientibus, 
dichotomis, ramulis repetito furcatis. 
This species already considered by Dr. Oldham a Cyclopteris belongs indeed to this 
genus in the real sense of Brongniart’s Cyclopteris, of which some mesozoic forms were 
subsequently ranged with Baiera, Br.; while those specimens from the Kajmahal Hills, which 
I have called Cyclopteris Oldhami, Fstm.,* belong to the sub-genus Cordiopteris, Schimp. 
Our specimen from Jabalpur resembles that form described by Dr. Schenk as Dicranop- 
teris Momeri, Schenk,f which is also a Cyclopteris and from rharticbeds. The only 
difference I see is in the slightly thinner veins, On the other hand it is scarcely to he 
distinguished from Cyclopt. ( Baiera) digitata, L. and H., from the lower oolite iu 
England; especially Lindley and Hutton, pi. (53, f. 1, and Brongniart, Hist. d. veget., tab. 
61 bis., f. 2. Our specimen seems to me not to be so deeply lobed.
