CARBONIFEROUS LYCOPODS AND SPHENOPHYLLS. 33 



Subsequently' Brongniart removed from the genus all the plants 

 originally placed in it except the Lycopodites falcatiis, L. and H., 

 from the Oolite." 



In 1855 Goldenberg added to the genus six new species fi-om 

 the Carboniferous of Saarbruck.^ 



Of these several have a great similarity in appearance to recent 

 Lycopods, especially in their foliage to some Selaginelhe. His 

 Lycopodites primoevus* and Lycopodites macrophyllus^ are described 

 as having distichous leaves. In i-eferring to these plants Solms- 

 Laubach points out that "it is only in the case of a few of the 

 heterophyllous Selaginella-like forms that the presence of the 

 small ventral leaves can be ascertained ; if the impression is seen 

 from above, they are of course concealed, but in the opposite 

 position also, they are usually withdrawn from observation 

 through their clinging close to the stem. For this reason all 

 Lycopoditte with distichous leaves may be reckoned without 

 hesitation among the heterophyllus forms. "^ 



Schimper places Goldenberg's Lycopodites denticulatus, L. 

 leptostachijs, and L. elomjatus' with leaves surrounding the stem 

 on all sides in Lycopodium} 



The position here taken by Schimper in the present state of 

 our knowledge seems scarcely tenable, as there are certain 

 important points in their structure of which our knowledge is too 

 incomplete to warrant our referring them to Lycopodium. It 

 therefore seems much more satisfactory to include at present all 

 in Lycopodites. 



Geinitz figures a very fine example of Lycopodites Gutbieri, 

 Gopp., showing the heterophyllous branches and terminal cones, 

 from Bockwa, Saxony." This and the majority of Goldenberg's 

 figures have been reproduced by Schimper.'"
