[vol. x. 
(1850) Goldenberg* was of the same opinion. Sir Charles Bunbury in general adopted 
Brongniart’s views about Noggerathia, and it seemed to him only doubtful whether it could 
not be a fern ; but “ the breadth and coarseness of the veins in the Nagpur plant, and a certain 
appearance of rigidity about the leaf,” looked already to Sir Charles Bunbury rather like a 
cycad than a fern (1. c. p. 335), while the dichotomy of the veins, their equality and uni¬ 
formity, and the absence of any trace of transverse connecting veins, plainly shews that it is 
not a Palm (1. c. 335), so that he would refer the plant rather to the Cycadeacece or an allied 
form. The resemblance of Noggerathia in its well-defined characters with some Zamiem 
is so striking, that there can be little doubt but that it belongs to this Order or very near. 
Already in previous papers (in Europe) I have considered Noggerathia as gymnospermous, 
as also Professor Geinitz does. Schiinper placed it (1870-72) quite distinctly with the Zamiete, 
as first genus; and also in my Flora of Kachf I quoted Noggerathia with the Cycadeacece, 
uniting Noggerathia with Cordaites to a special family, which, however, is only partly so, as 
some Cordaites may belong elsewhere, while Noggerathia remains a Cycadeacece. 
If we compare the carboniferous Noggerathia folisa, Stbg., with Sphenozamites Rossi., 
Ziguo, there is certainly a great similarity between them; and if we compare the fruc¬ 
tification in Goldenberg (1. c. PI. Ill, fig. 3) with the fructification of a living Zamia, there 
is certainly a striking resemblance. Our Damuda Noggerathia resembles very much the 
leaves of some living Zamiem ; so that all evidence seems to prove the views of Brongniart, 
that Noggerathia is a Cycadeacece and most probably a Zamiece. 
The Noggerathia from the Damuda Series supports strongly this view; and there is 
especially a specimen from Barkoi in the Satpura basin since many years in our collections 
which shews two leaves in their natural position as they were inserted on the stalk. 
Genus: Mackoftebygium, Schimp. 
Some of the triassic forms, which at first stood also with Noggerathia and Ptero- 
phyllum, were lately separated by Mr. Schimper with a special name, Macropterygium, 
with two species, Macropterygium (Noggerathia ) Bronni, Schimp., and Macropteryg. 
(Pterophyllum) giganteum, Schimp. Of these one is also in our Damuda Series ; I men¬ 
tioned already in Records IX, 4, p. 141, a specimen from the Lower Godavari District as 
Noggerathia Vogesicca, Bronn., which is Schimper’s Macropterygium Bronni, and there are 
from the Damuda Series in the Satpura basin for a long time exhibited several specimens 
of a Noggerathia- like form, only that they are much longer than the usual forms, and 
I suppose them to belong to Macropterygium, somewhat allied to Macropterygium Sclienki; 
a similar form I brought again this year from the Kurhurbalee coal-field, together with many 
other plants on which I shall report on a subsequent occasion. 
As far as is known now (1877), cycadeous plants are not so rare in our Damudas, at 
least more frequent than we find them in Carboniferous and Permian strata. There are 
known, not regarding those cycadeous plants which I brought from the Kurhurbalee coal-field 
and which are not yet described, four genera of cycadeous plants in our Damudas ; as it is 
rather an important point in the discussion on the relations of our Damudas, I shall give 
here the general view of the genera and species known to present date, with their localities 
and dates of discovery.
