Samaropsis Leslii sp. nov. The seed on which this species is founded was discovered by Mr T. N. Leshe in the Ecca beds (Permo-Carboniferous) of Vereeniging, South Africa, a locahty from which the same geologist has obtained leaves of Cordaites, Psyg- mophyllum, Glossopteris and other genera^. In the shghtly 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 Fia. 503. Samaropsis Leslii. From Vereeniging, S. Africa.
