CARDIOCARPALES 



[CH. 



that of Samaropsis (Samarospermum) moravica while sometimes, 

 as in the example shown in fig. '502, F, the broad border is pre- 

 served only at the sides. These seeds are abundant in the Santa 

 Catharina beds, where they were discovered by Dr Esdras do 

 Prado Seixas, in association with leaves of Gangamopteris, and 

 White thinks that they were borne on the fertile leaves of that 

 genus which he has named Arberia 1 . Although there is as yet 

 no proof of a connexion between Gangamopteris and seeds of this 

 or any other type it is almost certain that it was a seed-producing 

 plant. 



Samaropsis Leslii sp. nov. 



The seed on which this species is founded was discovered by 

 Mr T. N. Leslie in the Ecca beds (Permo-Carboniferous) of 

 Vereeniging, South Africa, a locality 

 from which the same geologist has 

 obtained leaves of Cordaites, Psyg- 

 mophyllum, Glossopteris and other 

 genera 2 . In the slightly cordate base 

 and tapered apex (fig. 503) the nucule 

 agrees closely with those of European 

 examples, but the Vereeniging type is 

 distinguished by its larger dimensions 

 and by the wider border indicating 

 a thick sarcotesta continued basally 

 into a stout stalk. The apex is 

 emarginate and a median rib marks 

 the position of a vascular strand. 

 There is no evidence as to the nature 

 of the parent-plant. 



Samaropsis indica (Zeiller). 



Prof. Zeiller 3 described this 

 species as Cardiocarpus indicus 

 from the Karharbari (Lower Gondwana) beds of India. An 

 examination of the type-specimens enables me to confirm the
