Both in the state of Santa Catharina and in the lower Gond- 
wanas of India there occur small, broadly pedicellate, spreading, ovate, 
oval, or rounded, deeply incised, coriaceous or striate and thicknerved 
scale leaves whose distant recurvate and truncate lobes appear to owe 
their abrupt or even. slightly ragged terminations to the detachment 
of some sort of bodies, presumably reproductive in nature. Bunbury 
described (1) a specimen from Kampti in India, as « Filicites (Glos- 
sopteris?)» and Feistmantei illustrated (2) a large and better pre- 
served example from the Talchir-Karharhbari division as an. « inflo- 
rescence » probably belonging to Noeggerathiopsis Hislopi. No further 
evidence as to the nature of these fossils was brought to light, and 
the question as to their generic relations has been in abeyance, even 
the type itself remaining without name. 
The discovery of specimens obviously of the same generic type 
in Brazil is interesting not only on account of the wide distribution 
indicated thereby, but also for the reason that the South American 
examples essentially confirm the reproductive nature of the fossil, 
though I believe they do not fully confirm Feistmantel’s opinion as 
to their relationship to Noeggerathiopsis. Our specimens represent 
a smaller and much shorter, oval. form, more briefly pedicellate and 
deeply, as well as much more narrowly, dissected than the specimens 
from the Indian rocks. 
The abrupily truncate lobes bear every evidence of separation 
from reproductive bodies, probably seeds, while the circumstancial 
evidence of association, juxtaposition and orientation point toward a 
connection with a small, undescribed winged Cardiocarpon (Sama- 
ropsis) Setxast. Absolute confirmation of the union of seed and leaf 
is lacking in our material, though the indistinct evidence of vascular 
connection is almost convincing. The reasons for regarding them as 
belonging to the same organism will be stated in the discussion of the 
Brazilian species.
