may happen that by the discovery of more and better specimens from the Jabalpur group, 
the identity with those forms will be proved. I point to these three forms specially, as in a 
general paper they might be overlooked; but the relations of our Indian Jurassic floras 
with those in Asia are much closer. 
If we take the flora of the Jabalpur-Kacli group, with the somewhat older flora of 
the Eajmahal group, then we find its representatives in South Russia (Izoum, near Kamenka), 
in Immeretia to the south, and Daghestan to the north of the Caucasus, in the Elburz 
mountains, near Astrahad, in Irkutsk (E. Siberia), in the Amur countries, in Japan, in 
China, west of Pekin, and in the Province Hoopeh ; and, according to Baron von Richthofen’s 
opinion, the coal-beds of Sze-Chwan, Yunnan, &c., are of about the same age. In my paper 
on the flora of the Jabalpur group I shall discuss these relations more in detail, showing 
the identities. 
3. A new Dicksonia L’ Hebit feom the Damuda Seeies, Pigs. 10—11. 
In the continuation of the Rajmahal Flora* I have described a Dicksonia as Dicks. 
Bindrabunensis ; but as at that time I was not aware of Prof. Heer’s work on the Jurassic 
Flora of Eastern Siberia and the Amur countries having been published, I said, page 23, 
that, “we do not find this name as a fossil genus.” I am glad to see that, although 
Prof. Hecr was prior in establishing the genus as fossil, I was also correct in my diagnosis, 
which I made independently. 
I have now to record a form from the Damuda series, which is very close to one of 
Prof. Heer's species. The specimens in question arc from the Raniganj and Jherria coal¬ 
fields : one of the specimens from the latter locality which were collected by Mr. Hughes, 
I have figured (fig. 10), and two leaflets are enlarged in figs. 10a and 106. 
The sub-opposite pinnse rise from the rhachis, at subacute angles, turning upwards. The 
chief rhachis and the rhachis of the pinnulse are traversed by a median line. The pinnulse are 
membranaceous, closely set, oblong, attenuated towards the base, pretty acute at their apex, 
and decurrent on the rhachis. 
The pinnulse, which are closer to the chief rhachis (about 3 or 4) have a sinuately 
denticulated margin, while those more distant have almost an entire margin, and only here 
and there the averted margin shows a slight sinuation. The enlarged pinnuke, figs. 10a and 
106, show this. 
There is a chief vein coming out more from the lower part of the base, but almost at 
the same spot a secondary vein passes out from the chief vein ; besides this, other secondary 
veins pass out at pretty acute angles and are forked. No fructification is preserved. 
There is especially one species in Prof. Heer’s work on the Flora of the Amur countries, 
Dicksonia concinna ( l. c.), page 87, to which our form is closely allied; and Heer’s fig. 2, 
on tab. xvi, approaches very much my drawing, so that I consider both as belonging to 
the same group. 
In fig. 11 is a pinna of another specimen, which approaches still more Heer’s 
drawiugs. 
This is not the only form in our Damudas which is a Siberian element. Prof. Heer 
describes a Phyllotheca Sibirica, to which, as he himself remarks, the Phyllotheca a ustralis, 
McCoy, is most closely allied; but also our Phyllotheca indica, Bunb., from the Raniganj 
group, is almost undistinguishable from the Jurassic form in Siberia.
