Types referable to the ferns appear to be rare, both in species and 
number, nearly everywhere in the lower Condwana flora of the 
lvastern hemisphere, andthey are also very rare, so far as known, 
in the coal flora of Southern Brazil, there being but two small 
fragments, both referable to the genus Sphenopteris in the collections 
before me. 
The cccurrence of Psaronius in the states of Piauhy and Sdo 
Paulo a little to the north, and the evident nearness of Brazil to the 
Northern Permian flora, as shown by the number of Northern Lepi- 
dophytic genera, lead us to look forward to the discovery of a larger 
filicate flora including members of Pecopteris or Cladophebis and other 
genera more common in the Northern floral province.

The fragment shown in Plate VI, Fig. 1, is the sole represen- 
tative, in the collection, of the closely related group which includes 
the species named above. Unfortunately the soft arkose matrix yelds 
such obscure traces of the nervation that the identification must re- 
main uncertain pending the discovery of more material. The plant in 
hand differs from Sphenopteris Hughesi (Feistm.) Zeiller (1) by its 
more broadly triangular, short, subordinate pinnae, and the narrowly 
alate rachis, though the subdivisions are in some cases similar in form 
and lobation. 
Professor Arber (2) has recently referred Sphenopteris hastata 
together with McCoy’s Sphenopteris plumosa, Sphenopteris germana 
and Sphenopteris flexuosa to Sphenopteris lobifolia Morr. The union 
of the three spacies first mentionel, all of which come from the same 
locality, Mulubima, New South Wales, would s2em to be well foun-
