Arberia minasica n. sp. 
Pl. VII Figs. 8, 9. 10. 
Fertile scale-fronds, small, round to oval in contour, briefily and 
rather narrowly pedicellate, more or less concave-convexr, very deeply 
dessected along a narrow, rapidly difuse axis in numerous oblique, 
linear, divergent, often recurved divisions which, near the apex, 
may, fork again into short, narow, devaricate, and, so far as obser’ 
ved abruptly truncate subdivions ; lanuna thick, flat, and coarsely 
striaterugose in the distal portions ; nervation derived from seve- 
ral vertical parellel, coarse primary nerves which fork to provide 
a secondary nerve for each division of the leaf, the divisional 
nerve bifurcating to supply a branch for each subdivision, and 
at the same time spreading in a broard fascicle on approaching 
the truncate apices in which the fascicles abruptly abut; fru- 
ctification probably a seed borne at the apex lof each subvision 
or lobe. 
The aspect of the inflorescences here described is so well shown 
by the fragments photographed. in Pl. VIII, figs, 8, 9, 10, as to 
require little further description. At first glance they suggest a 
small, deeply dissected, rugose or coriaceous, recurvate and truncate 
lobed Aphlebia. The base is narrow, and the entire fossil has the 
appearance of having been rather thick in texture. 
The nerves are distant and strong beneath the striate-rugose epi- 
dermis, which becomes especially tibrous in aspect in the flattened 
lobe. The latter, particulary those near the base, curve more or less 
distinctly toward the ventral side which is concave. 
With these scales, which are not rare in the Gangamopteris 
bed northeast of Minas, are large numbers ofa species of Samaropsis 
Seixasi, sometimes in such position and orientation as to raise the 
question as to whether they have not once been, if they are not 
now, in actual union. The question of organic union is one difficult 
of decision on account of the partial maceration of most of this 
material and the frequent discoloration of the rock by iron in pro- 
ximity to the vegetable remains. But in two examples, one of which 
is shown in fig. 8, there seems still to be vascular connection 
between the truncate lobe and the base of the immature nutlet. In 
support of the hypothesis of derivation of the Samaropsis from Ar-
