Remarks. — I previously regarded Calamites undulatus, Sternb., as a varietal form — 

 probably of Calamites SucJcowii, Brongt. — but now believe it to be a distinct species. 

 Calamites undulatus is most easily distinguished from Calamites SucJcoivii by the ribs 

 being undulate (but this character may be removed by pressure), and by their termin- 

 ating at the nodes in sharp triangular points — not being rounded, as in Calamites 

 Suckoivii.
