of a part of the new material, acompanied by a discussion of the 
distribution of the lower Gondwana flora, illustrated by a manuscript 
map. The abstract of the proceedings of the meeting (1) records the 
occurrence of Glossopteris indica, Gangamopteris obovata, Gangamo-~ 
pteris cyclopteroides, Phyllotheca cf. australis and Noeggerathiopsis 
Hislopi in beds about 55 meters above the old crystallines near (Minas) 
Lauro Muller in the State of Santa Catharina; Glossopteris indica, 
Neeggerathiopsis Hisloppi, Ottokaria sp.,and Cardiocarpon sp. from 
Irapua coal in the State of Rio Grande do Sul. Attention is called to the 
fact that, in accordance with the stratigraphical observation of Dr. 
I, C. White, geologist and Chief of the Commission, the beds with 
Lepidophytes are stratigraphical a little higher thant those with the 
plants last enumerated. This material is more fully discussed in the 
following pages. 
Sources and stratigraphic relations of the collections treated 
in this report 
The fossil plant materials treated in this report consist almost 
entirely of collections made under the personal supervision of Dr. I. C. 
White the Chiefof the Brazilian Coal Commission in the seasons of 
1904 and of 1905, and by Engineer Esdras do Prado Seixas in 
1905. The greater part of the fossil come from the coal fields of 
State of Santa Catharina, of whose coal flora we hitherto have had 
practically no information. This flora is the more interesting since 
its source is in the state to the north of Rio Grandedo Sul, and 
soa little nearer the typical Northern flora. 
Thanks to the distinguished ability and great familiarity with 
Coal Measures stratigraphy on the part of Dr. White, nol only have 
the structural relations of. the basins and the stratigraphical positions 
of the plant-bearing horizons been made out, but in some instances, 
at least, individual beds have been correlated between the basins. 
This is the more important, if more difficult also, since the Coal Me- 
asures of these states rest in immediate unconformable contact on 
the eroded surface of the old granite and other ancient crystallines. 
Accordingly, in enumerating the several plant localitiesin the region 
of Minas in the State of Santa Catharina, reference will, in many
