﻿WHITEj THE SEEDS OF ANEIMITES 33 I 



reasonable confidence be provisionally included within the broader 

 scope of an order, the Lyginodendrales. In accordance with the 

 classification of the supposed Cycadofilic types recently proposed by 

 Professor Lester F. Ward, 1 this order will fall within the class 

 Pteridospermav and the phylum Pteridospermaphyta. 



The discovery of Pteridospermic characters in Ancimites, in which 

 they had not been suspected, throws serious suspicion on the sterile- 

 frond genera, Eremopteris 3 Pseudopccoptcris, and Triphyllopteris, 

 which appear to be most closely connected to Ancimites by the 

 characters of their fronds, and whose fructification is wholly un- 

 recognized. 



The habitual association of Wardia with the foliage of Ancimites 

 (Adiantites) at a number of localities suggests that the seeds from 

 Altendorf figured by Stur 1 as Rhabdocarpus conclucformis Goepp., 

 which resembles Wardia in many respects, may possibly be the fruit 

 of one of the species, also from Altendorf, described and figured 

 by the same author as Adiantites antiquus and A. Machaneki.
