84 LYCOPODIALES [CH. 



Inferior Oolite rocks of the Yorkshire coast bearing "small 

 round crowded leaves," which was afterwards described by 

 Lindley from additional material obtained from Cloughton 

 near Scarborough as Lycopodites falcatus. The example re- 

 presented in fig. 137 shows the dichotomously branched shoots 

 bearing two rows of broadly falcate leaves. A careful examina- 

 tion of the type-specimen^ revealed traces of what appeared to be 

 smaller leaves, but there is no satisfactory proof of heterophylly. 

 No sporangia or spores have been found. This British species 

 has been recorded from Lower Jurassic or Rhaetic rocks of 

 Bornholm^ and a similar though probably not identical type, 

 Lycopodites Victoriae^, has been recognised in Jurassic strata 

 of Australia (South Gippsland, Victoria). An Indian plant 

 described by Oldham and Morris* from the Jurassic flora of the 

 Eajmahal hills as Araucarites (?) gracilis and subsequently 

 transferred by Feistmantel to Schimper's genus Cheirolepis^ 

 may be identical with the Yorkshire species. The Jurassic 

 fragments described by Heer from Siberia as Lycopodites 

 tenerrimus^ may be lycopodiaceous, but they are of no botanical 

 interest. 



Other examples of Mesozoic Lycopods have been recorded, 

 but in the absence of well-preserved shoots and sporangia they 

 are noteworthy only as pointing to a wide distribution of Lyco- 

 podites in Jurassic and Cretaceous floras'". 



From Tertiary strata species of supposed herbaceous lycopods 

 have been figured by several authors, one of the best of which 

 is Selaginella Berthoudi Lesq.* from Tertiary beds in Colorado. 

 This species agrees very closely in the two forms of leaf 

 with Selaginella grandis, but as the specimens are sterile we 

 have not sufficient justification for the employment of the 

 generic name Selaginellites.
