Several of the rock specimens before me contain detached ver- 
tucils of theleavesofa large Phyllotheca, two fragmentary examples 
of which are illustrated in Pl. v, Figs. 9 and 10. All are more or 
less macerated so as to give a probably. unduly lax aspect to the 
leaves. On first inspection of the material I was disposed to regard 
it as belonging to Phyllotheca australis Brongn., on account of the 
close similarity to the exemples shown by Feistmantel in figures 
2 and 3, plate xiv, of his memoir (1) on the Palaeozoic and Mesozoic 
flora of Eastern Australia and Tasmania. The examination of the 
earlier descriptions and illustrations, as well as of specimens from 
the Newcastle Series in the Unlted States National Museum, convin- 
ces me that our plant lacks the erect sheath and rigid leaves cha- 
racteristic of the Australian species, as shown by Dana, (2) Jack & 
Ethridge, (3) and others. On the contrary, the rapidly fiaring sheath, 
the backward curved leaves, which are somewhat lax and upturned 
near the apices, and the narrow midrib, ventrally depressed in the 
leaf, seem to show a complete specific identity with the species des- 
cribed by Zeiller from the Barakar group in the South Rewah basin 
of India. The illustrated specimens of Phyllotheca equisetitoides des- 
cribed by Schmalhausen (4) from the Permian of the-lower Tun- 
gusca in Siberia, bear’ a close resemblance to our plant, though the 
leaves are proportionately narrower. 
The apices are very rarely seen in the Brazilian specimens, on 
account of the poor preservation. As a rule the leaves are propol- 
tionately a little broader than those in Zeiller’s type specimen. 
Occasionally they attain a considerable width, as is seen in the 
small fragment, Fig. 9. In the specimen photographed in Fig. 10 it 
will be noticed that the leaves of more than one verticil are super- 
posed, indicating the shortness of the internodes. It is possible that 
the slender stem fragment shown as «Schizoneura? sp.» in Fig. 6 
of the same Plate, represents the stem of this species, its costalion 
being nearly equal in width to that indistinctly seen in the branch 
on the left in Zeiller’s figure. ;
