768 MR ROBERT KIDSTON ON THE FOSSIL PLANTS OF 



Stigmaria rimosiformis may belong to the genus Stigmariopsis, Grand' Eury. The 

 internal structure of these two rhizomes is unknown, but the ridges on the surface are 

 probably the external indications of sclerenchymatous bands in the outer cortex, which 

 is one of the characters of Stigmariopsis, but is a character not observed in any 

 specimens of undoubted Stigmaria which have shown their internal organisation. 

 Locality A. 



Fossil Plants of the Lower Coal Measures. 



All the fossil plants from this division were collected from the coals at present being 

 worked at Rowanburn. 



In addition to the specimens collected by ourselves, Mr Kenneth Bowie showed us 

 examples of Catamites undulatus, Sternb., and Catamites Cistii, Brongt. 



Filicacese.
