The seeds from Minas havea number of close relatives in the Nor- 
-thern Permo-Carboniferous flora, though none of the latter approach 
so closely the combined features of nucellus and wing, as to make 
difficult the specific distinction, 
The form of the nucellus closely approaches that of the seed 
published by Schmalhausen (1) asa Ginkgo-fruit, from Siberia. 
As noted in my remarks on Arberia there is some evidence, 
insufficient as yet, indicating a union of Cardiocarpon Seicasi with 
the truncate lobes of Arberia minasica, fertile leaves possibly belonging 
to Gangamopteris obovata. However, in view of the general asso- 
ciation of the Samaropsis forms in members of the Cordaiteae in the 
Northern flora, and with Noeggerathiopsis in the Southern, I place the 
species with the Cordaitales. Yetit is certains that not all of the

Seeds very small, nearly round, with a rather broad chalaz ; 
nucellus ovate-round, 5 mm or less tr altitude and 3,5 mm in trans- 
verse diameter, slightly spicwiale, densely striate ; sclerotest well 
marked, narrow at base and nearly 76 mm at widest near the apex ; 
sarcotest very thin al the base, dnd broadening upward to a width of 
1.5mm at the apex which ts slightly enarginate to short micropylar
