204 FLOEA OF LOWEE COAL MEASUEES OP MISSOUEI. 



specimens, supplemented by a large number of detached and only partially 

 compressed bolsters. Associated with this species are also certain leaves 

 which, to judge by circumstantial evidence, are not likely to have grown 

 on any other type of cortex. 



As fructifications of this genus fi-agments of cortex, cones, scales, or 

 sporocysts, and Cordaianthus-like racemes, have been described by various 

 authors. Of these supposed fruits I have seen only certain Lepidocystes or 

 Polysporia, and the singular remains figured by Lesquereux^ as belong- 

 ing' to L. dikdatus, a species very closely related to L. Van Ingeni. The 

 originals of the figures of the supposed fruits, now in the Lacoe collection 

 in the United States National Museum, are certainly both problematical 

 and interesting ; but while they no doubt represent a single type by them- 

 selves, there hardly seems to be sufficient reason for consideiing them as 

 pertaining to LepidopMoios, and I shall not therefore further discuss their 

 structui-e or relation in this place. 



The fragments of cone described by Goldenberg^ and Von RoehP 

 probably belong to some large species of Lepidophyllum, such as L. majus. 

 The similarity of the bracts of these cone fragments to the leaves on the 

 branch of the Lepidophloios acerosiis L. and H., illustrated by Kidston,* is 

 at least very suggestive. In another place I have described as Lepidopliyllum 

 (Lepidostrobus) missowriensis, a species frequently found associated with 

 fragments of the Lepidophloios. The fragment, PI. LX, Fig. 1, apparently 

 representing a cone of this species, which I am inclined to consider as 

 referable to the Lepidopldoios, merits a comparison with the bracts or leaves 

 figured by Goldenberg and Kidston. It is perhaps a significant fact that 

 generally in the American Coal Measures some large Lepidopliyllum is 

 reported from the same locality as one of these species of Lepidophloios. 

 Examples are Lepidophloios dilatatus and Lepidophyllwn Mansfieldi from 

 Cannelton, Pennsylvania, Lepidophloios auricidatus and Lepidophyllwn auric- 

 ulatum from Morris, Illinois. Caution, however, must always be used in 

 considering the argument of coincidental occurrence. 



Quite unlike any desci'ibed Paleozoic Lycopodineous fruit are the
