Zeitschr. d. Deutsch. geol. Gesell., vol. xviii, opp. p. 770. 
Leaf cushions or bolsters prominent, and projecting slightly 
upward, rhombic, sometimes broadly rhombic, close often “ounded 
at the lateral angles, not carinate below the leaf scar ; leaf scar 
placed at a point about three fourths of the lenght of the bolster, 
relatwely large on the more mature stems and branches, very bro- 
adly rhomboidal, laterally acute, the upper and lower angles well 
rounded ; cicatricules punctiform, the parichno a little distant. 
This, the first Lepidophytic type to be reported from Brazil, is 
represented in the collections by several impressions on flat frag- 
ments of coal. They arein very low relief and consist for the most 
part of slightly encrusted moulds in layers of smutty «mother of 
coal» or natural charcoal. One of the specimens presents a Avorria 
stage exactly similar to that photographically illustrated by Pro- 
fessor Zeiller in plate 8, figure 4, of his valuable paper, «Note sur 
la flore fossile des gisements houillers de Rio Grande do Sul (Brésil 
méridional), printed in the 23rd volume of the Bulletin de la So- 
ciété géologique de France.» (1) 
Two slabs in the collection made by Doctor White are covered 
with narrow small leaves exactly like those shown in Figures 5 
and 6 on the plate above cited. Notwithstanding the position of the 
stomatiferous grooves so near to the border, a character which in- 
clined Professor Zeiller to regard them as possibly leaves of <Szgil- 
laria. I am disposed to consider them the leaves of Lepidodendron 
Pedroanum. The lateral or parichnoian cicatricules of the leaf scar,
