which it is particularly close to Cardiocarpon orbiculare Newherry 
(1) from the lower portion (Westphalian) of the upper Carboniferous 
of Ohio. The species constitutes another link binding the flora of 
Brazil to that of the Northern Permo-Carboniferous, the connection 
in this instance being the more interesting it is Gymnospermic or 
Pteridsspermic. 
Cardiocarpon Oliveiranum is named in honor of the distinguished 
veteran geologist of Brazil, Dr. F. de Paula Oliveira. 
Localities : Estrada Nova, near Minas, Santa Catharina. About 
40 meters below the Barro Branco coal, or about 135 meters above 
the granite, Lot 3923 (type). Also from a horizon about 10 meters 
above Rio Tubarao, near Minas. Lot 3588.

Nucellus cordate, about 5mm in length and a little more in 
breadth ; sclerotest narrow, dense ; sarcotest broad, measuring 3mm 
in width at the narrowest point, opposite the middle of the nucellus, 
and broadening to 5 mm in passing around the aper there tt is but 
slightly emarginate at the end of the distinct micropylar canal, and 
prolonged downward below the nucellus for a distance of about 
3.5mm soasto give the entire seed a nearly oval or slightly obovate 
oval contour, the length being nearly one half qgreaterthn the 
greatest breadth, 
The specimen figured is the only one of its kind in the collec. 
tions. The almost exactly cordate nucellus is slightly convex, anda 
line of carbon indicates the density of the sclerotic envelope. The 
outer envelope was evidently somewhat dense, for although slightly 
deformed in the course of fossilization considerable carbon still adheres 
to the impression. The broad extension of the wing or sarcotest 
and the apparently equal thickness of the latter throughout, entitle 
the speciestoa place in the Samearopsis section of the genus. 
Few specimens described from the Gondwana flora are compa- 
rable to that figured in P. X Fig. 11. Among these the incomplete
