as shown in one of our specimens, were found (1) to be small and 
distant, essentially in agreement with the position of the stoma- 
tiferous tracts. 
The association of the fragments favors this correlation. Ho- 
wever, it is not yet definitely proven that the leaves, sowell figured 
by the learned French paleeobotanist, were borne by Lepidodendron. 
Zeiller’s suspicion, based on these leaves, that Sigillaria was present 
in the brazilian coal measures was in a way, prophetic, since the 
genus is present in our collections, as will later be shown. 
The larger trunk fragments of Lepidodendron Pedroanum are 
characterized by the relatively broad leaf cushions, and the unusual 
width of the leaf scars. This feature, taken together with the char- 
acteristically high and prominent position of the leaf scars on the 
leaf cushions and the vertical foreshortening of the latter in many 
of the fiattened impressions, frequently give the specimens the as- 
pect of a Lepidophloios. This similarity is well shown in Zeiller’s 
figure 3 on plate viii. 
Lepidodendron Pedroanum is probably most nearly related to 
Lepidodendron obovatum Sternh. of the northern flora. It is also to 
be compared with Lepidodendron dichotomum Sternb. Some aspects 
of the cortical impression call to mind the Lepidodendron oculis felis 
of Abbado(2) from beds which should not be far from the base of 
the Permian in the province of Shansi, China The large stems of 
the Southern species are so well illustrated by Zeiller as to require 
no further illustration. 
The features of the smaller stems or branches are well shown 
by Carruthers and Arber, in the papers already cited. On account 
of the close resemblance between some of the branches figured hy 
various authors as Lepidodendron Sternbergit and the corresponding 
parts of Lepidodendron Pedroanum it appears to me probable that the 
stems listed, but not described nor illustrated, hy Bodenhender (3) 
under the former name really belong, as has been indirectly sug- 
gested by Arber, tothe species described by Carruthers from Brazil.
