the Lepidodendron Sternbergii of Bodenbender’s paper is placed 
under Lepidodendron lycopodioides, and the Euryphyllum Whittianum 
is referred to the genus Noeggerathiopsis, as Noeggerathiopsis Whit- 
tiana. The above synopsis embraces I believe, the lower Godwana 
flora, so far yet known, of the Argentine Republic. 
Returning to the flora of Brazil, we find the Brazilian especies 
briefiy discussed, with a summarized distribution, in Arber’s mono- 
graph to which reference has just been made. The species enume- 
rated by him embrace a complete list of the Permo-Carboniferous 
plants known from Brazil prior to the exploration carried on by 
Dr. I. C. White under the auspices of the Coal Commission, viz:

Mention should also be made of several types not included by 
Arber, but more or less indefinitely reported from Brazil, as shown 
in the above historical review, viz: 
Glossopteris sp., Plant, in Hartt, 1870. . . . . . . Rio Grande do Sul. 
Asterophyllites (2) scutigera (Phylotheca), Hartt, 1870. . Bahia.

Cordaites wood, Derby in Renault, 1892. . . . . . Ss. Paulo, 
Sligmaria (2?) sp., Zeillor, 1895. . . 2... ee Rio Grande do Sul. 
All of the above fossils, with the exception of Psaronius brasi- 
liensis, the Asterophyllites, and the fossil woods, appear to have come 
from .Rio Grande do Sul, 
Professor Arber’s monographis, so far as I am aware, is the last 
publication touching the Brazilian coal flora. I have, however, 
omitted a brief abstract which antedates his memoir and which 
deals with the material collected by the Coal Commission, 
In March, 1905, 1 informally contributed to the Geological Society 
of Washington a preliminary statement of the results of the study
